L INTRODUCTION Drilling operations for Northwest Eileen #1-01 were initiated 02-11-97, by BP Exploration - Shared Services Drilling. The well was drilled by Nabors Alaska Drilling Rig 18-E on an ice pad location that had been constructed earlier in the winter. The ice pad was located in Section 34, Township 12 North, Range 11 East in the west end of the Prudhoe Bay Unit. The well was planned as a moderate reach directional hole to penetrate targeted sands found in the Kuparuk Formation predicted on this location. North West Eileen 1-01 was drilled to a total depth of 10,531' on 3- 04-98. The total number of operating days that was required to reach this depth were 22 days including the spud in date. Operations to plug and abandon the well were completed 3-06-98, after completing Logging Operations for the 6" hole section of this well. A Sperry-Sun Logging Systems LS2000 Unit was in operation from surface to TD providing full mud logging and applied drilling technology services. The 2000 Unit and crew provided assistance in the drilling of NEW 1-01 by monitoring essential drilling parameters and gas levels. Also provided were fluid hydraulics information, pore pressure vs. necessary mud weight evaluations, and a wide range of geologic interpretations and sampling services. Additional services included the integration of real-time Gamma Ray and EWR information from data supplied by a separate MWD company, Anadrill Schlumberger. The following pages of this report are designed to supply concise historical data of the events that occurred on NEW 1-01, along with some analysis and recommendations for specific problems that were experienced during different sections of the hole. All of the information compiled in this report was acquired and recorded by the LS2000 Unit at the well site. The sensors incorporated in this unit are independent from the rig sensors and may differ slightly from those reported by the rig contractor. In addition, any evaluations in this report regarding formation evaluations, pore pressure estimates, or other geologic interpretations are made entirely by Sperry-Sun personnel from examination of the data collected by the LS2000 Unit and reference material made available by the Operator at the rig site.

TD 10531'MD 72~' TVD WELL SUMMARY BY INTERVALS Interval: 110'-3,355' Days: 4 Average WOB: 25 klb Hole Size: 12.25" Average RPM: 160 No. Bits: 1 Average GPM: 555 gpm Rotating Hours: 21.2 Average SPP: 1850 psi Deviation: 0 - 60.4 deg Average ROP: 153 ft/hr Mud Weight: 8.7-10.3 ppg Mud Type: Spud Mud Nabors Alaska Drilling Rig 18-E was. positioned on location prior to the spud in date of 02-11-98. Structural 20' drive pipe had been set to a depth of 110'. After completing the rig up, a surface diverter system was installed and tested. Drilling operations were initiated by drilling out the structural casing with Bit No. 1 that was nm into the hole on a directional assembly'with a 1.5 degree motor. The directional part of the well was started at approximately 300' occasionally sliding to build angle and maintain direction. The angle of the hole was steadily built to a maximum for this interval of 60.4 degrees recorded from a survey taken at 3,270'. Penetration rates for the first bit run were good while drilling through the Permafrost in mostly gravel and sand. Gravel drilled in this formation was not very large in diameter and did not appear to slough excessively. The mud weight was gradually increased beginning at 1,200' to a weight of 10.2 ppg by 1,500' in anticipation of drilling into hydrates expected in this area. A short trip back to 655' was performed at 1,410' to condition the hole. The maximum gas readings recorded from the this trip was 18 units. Our estimate for the base of the base of the Permafrost was logged at approximately 1,840'. Gas hydrates were encountered just below this threshold beginning at 1,875'. High background gas readings averaging 3,000 units were logged while drilling to 2,150'. The background reduced to an average of 500 units until penetrating what appeared to be a second hydrate zone starting at 2,400'. High gas readings averaging 2,000 -3,000 units and consistent connection gas readings were logged for the remainder of the 12 ¼" interval making it difficult to estimate any additional hydrate zones strictly from gas readings. Electric logs were not needed for the 12 ¼" section. A 14 stand short trip was performed at 2,708' and recorded a maximum trip gas reading of 7,865 units. Bit No. 1 was then used to drill to the interval depth of 3,355'. The hole was conditioned with a wiper trip back to 260' in preparation for nmning casing. The maximum trip gas recorded circulating after this trip was 2,822 units. 9 5/8" - 40 lb/ft casing was run to a shoe depth of 3,340'. The casing was then cemented in place using a two stage cement job. ' This interval of the well is believed to be near normal pressure. High background gas and connection gas readings were logged after penetrating into gas hydrates starting at 1,875'. These gas readings were believed to be associated with melting hydrates rather than free gas bleeding into the well bore. A gradient of 8.5 ppg was estimated for the Permafrost section. This estimate was raised to 9.2 ppg upon penetrating the trapped hydrates at 1,875'. The estimate was reduced to 9.0 ppg relative to the clay formation at the casing seat. The average mud weight used below the Permafrost was 10.2-10.3 ppg and appeared to provide for an adequate overbalance condition to stabilize the well bore. Interval: 3,355' to 9,718' Days: Hole Size: No. Bits: Rotating Hours: Deviation: Mud Weight: 11 Average WOB: 5-12(PDC) klb 8 1/2" Average RPM: 305 2 Average GPM: 560 gpm 44.4 Average SPP: 2350 psi 65.2-21.1 deg Average ROP: 143 ft/hr 9.2/10.1 ppg Mud Type: LSND Discussion: The blow out preventer stack was nippled up and tested. The 9 5/8" surface casing was tested to 3,500 psi for 30 minutes prior to drilling out of the casing cement. Bit No. 2, a 8 1/2" PDC type bit, was used to drill out of the 9 5/8" surface casing along with 20 feet of new hole to 3,375' on 2- 15-98. The hole was then circulated with 9.3 ppg LSND mud in preparation for running a leak off test. The test that was performed at this depth yielded a fracture pressure equivalent to 13.3 ppg. The 13.3 ppg value observed at this casing seat is normal for this area of the North Slope. Bit No. 2, run on a directional assembly with a 1.5 degree motor, was used to drill ahead after completing the leak off test. High background gas readings were encountered from two sands drilled in the Ugnu between 3,410'-3,570'. Chromatograph breakdowns of the gas encountered in these sands were predominately methane. Hydrocarbon shows that were logged from these sands indicated the presence of low gravity oil. A short trip was made at 4,702' to condition the hole pulling the bit back to the 9 5/8" shoe. After drilling ahead, the maximum gas recorded from this trip was 145 units. The pore pressure estimate for the Ugnu was reduced to 8.7-8.8 ppg relative to the lack of connection gas and the low short trip gas reading. Low background gas readings continued while drilling in the Ugnu Sands to a depth of 5,200' maintaining the mud weight at 9.3/9.4 ppg. From this depth, moderately high background gas readings were recorded in individual sands for the remainder of the Ugnu Formation. Shows of fluorescence logged in these sands were believed to be associated with low gravity oil. Another short trip (15 stands) was performed at 6,228' to condition the hole. The maximum gas recorded after drilling continued with Bit No. 2 was 540 units. A significant change in the type of background gas was noted after drilling through a tight sand starting at 6,600'. Chromatograph breakdowns from high background gas readings from this zone contained good quantities of ethane though pentane. In addition, shows of oil fluorescence improved considerably and indicated the presence of lighter gravity oil. High background gas and fair quality oil shows were logged in two separate zones of the West Sak - Schrader Bluff Formation extending from 6,600'-6,645' and 6,680'-6,745'. The lower of these two zones appeared to have the best porosity and recorded a maximum gas reading of 5,400 units at 6,715'. The remainder of the West Sak - Schrader Bluff sands exhibited oil shows of poor quality mainly because of poor porosity estimates. The lithology changed to predominately siltstone below the sands in the West Sak - Schrader Bluff Formation. Occasional connection gas readings were also recorded in this change. A short trip back to 6,277' was performed at 7,759' to condition the hole. The maximum gas reading from bottoms up was 1,637 units. The pore pressure estimate was raised to 9.2 ppg to reflect the change in gas parameters and hole conditions while drilling in the Seabee Formation. Drilling continued with Bit No. 2 occasionally sliding to reduce the angle as directed by the well plan. The formation pressure estimate was raised to 9.4/9.5 ppg after penetrating below 9,300' in the Torok Formation based on a notable increase in background and connection gas readings. The formation pressure estimate was again raised to 9.6/9.7 ppg after penetrating the top of the HRZ. The total depth for this interval of 9,718' was reached on 2-19-98. The mud weight was raised to 9.8 ppg prior to conditioning the hole with a wiper trip to the 9 5/8" casing shoe. The maximum trip gas recorded from this trip was 1,625 units. Bit No. 2 was then pulled out of the hole to run electric logs. The first two wire line runs were made without problems; however, Run #3 included a RFT Tool to take fluid and pressure samples and would not go past 4,200'. A fourth run to take side wall cores also failed to get past 4,200' +/-, an area of the hole that recorded the maximum surveyed hole angle. The hole was then conditioned with a wiper trip using Bit No. 3 run on a conventional bottom hole assembly. The maximum gas recorded from this trip was 1,030 units. Bit No. 3 was then pulled out of the hole running a multishot survey on the way out. Side wall cores were then taken in the open hole on wire line. 7" - 26 lb/ft casing was then run to bottom at 9,718' without encountering problems. This casing was cemented in place using a two stage cement job. Full mud returns to surface were recorded while running casing and pumping and displacing the first stage cement. Mud returns were lost to the formation while pumping and displacing the second stage. Two show reports were completed for this section of the hole and included evaluations for the Ugnu and West Sak - Schrader Bluff Formations. Oil shows of fluorescence and cut were recorded in drill cutting samples collected throughout both formations. Analysis from gas readings and cuttings fluorescence taken in the Ugnu indicated the presence of low gravity oil in individual zones primarily in the upper part of this formation. This evaluation changed somewhat after penetrating into the West Sak - Schrader Bluff which appeared to contain lighter gravity oil. Although the overall show rating for this zone was poor, this was mainly due to poor porosity estimates. The oil in the sands below 6,600' appeared to be of good quality, particularly between 6,680'-6,735'. Please refer to the Conclusion and Show Report Sections of this report for additional analysis. The lithologies of this section consisted of gravel, sand, clay, siltstone, shale, sandstone, coal, and thin tuff beds. No abnormal gas readings were encountered, however high background gas readings were logged in the Ugnu and Schrader Bluff Formations where hydrocarbon shows were prevalent. The pore pressure estimate for this section of the hole ranged from 8.7 to 9.7 ppg establishing an increasing gradient below 7,600'. Hole problems for the interval were moderate and were mostly associated with problems encountered while trying to nm wire line logs. Interval: 9,718' to 10,531' Days: Hole Size: No. Bits: Rotating Hours: Deviation: Mud Weight: 7 (to TD) Average WOB: 12/12 klb 6" Average RPM: 75/265 (PDC) 3 Average GPM: 157/220 gpm 62.8 Average SPP: 2300/3600 psi 17.4 - 12.5 deg Average ROP: 13 flJhr 12.2 ppg Mud Type: KCL Poly Discussion: The blow out preventers were modified changing out the pipe rams for 3 ½" pipe and tested prior to running in the hole with Bit No. 4~, a 6" insert bit. The casing was tested to 3,500 psi prior to drilling out the ES Cementer from 7,294' which was associated with the first stage cement job. The second stage cement was tagged at 9,545'. After drilling cement to 9,632', the casing was tested again to 3,500 psi and held at that pressure for 30 minutes. The rest of the cement, float equipment, and casing shoe were then drilled along with 27' of new hole to 9,745'. A formation integrity test was taken yielding a pressure equivalent of 16.2 ppg. The hole was then displaced with weighted 12.2 ppg KCL Poly mud in anticipation of coting abnormal injection pressures predicted to be found in the Kupamk Formation. This mud weight was determined from the maximum recorded flow pressures from this formation in nearby Kuparuk production wells. Drilling rates were slow for Bit No. 4 averaging about 12 fph. The main contributing factor for the slow penetration rates was the observed overbalance supplied by the 12.2 ppg coring fluid drilling in a shale/siltstone formation in the area of 9.8 ppg pore pressure. Bit No. 4 was used to drill to 10,025', the selected core point for this well using MWD data to correlate with nearby wells. The hole was then conditioned with a 3 stand short trip and additional circulating time. Bit No. 5 was made up on a 60' core barrel and rrm into the hole. Core No. 1 was cut from 10,025'-10,085' and recovered 56' of formation. This bit was again run in the hole for a second core on a 90' core barrel. Core No. 2 was cut from 10,085'-10,156' and recovered 27' of formation. Background gas readings for both core hms were low averaging 50-60 units. In addition, oil fluorescence evaluations from drill cutting samples from both cores indicated that the Kupamk "C" target on this well appeared wet. Bit No. 6, a PDC type bit, was run into the hole after laying down the 90' core barrel. This bit was used to drill the remainder of the 6" interval to the total depth of 10,531' for NWE 1-01 on 3-4-98. Low background gas readings and poor show of fluorescence were logged throughout this interval The hole was then conditioned with a short trip back to the 7" casing shoe recording a maximum trip gas reading of 85 units. Bit No. 6 was pulled out of the hole and the well was evaluated with wire line logs. Two show reports were filled out for the 6" interval of this well relative to the targeted zone of interest. Minor oil shows of fluorescence and cut were recorded in drill cutting samples collected in this interval. Ratio analysis from gas readings taken in this zone indicated the presence of minor amounts of residual oil. The lithologies of this interval consisted of shale, siltstone, and sandstone. Hole problems for the interval were minor and included slow penetration rates due to mechanical factors. The 12.2 ppg mud weight used to drill this sectio.n provided sufficient overbalance to safely drill through the observed pressures that appeared to be much less than this gradient. GENERAL: CONCLUSIONS The drilling program for NWE 1-01 was designed to penetrate to an estimated measured depth of 10,500' and evaluate sands located in the Kupamk Formation predicted below 6,500' true vertical depth. This well is now one of four wells that have been drilled in this area to evaluate the Northwest Eileen Prospect. NWE 1-01 was drilled to 10,531' in 22 days and reached the projected total depth for the hole close to the 20 days originally estimated to drill this well. Initial plans called for testing the well through a production liner. The original plans to test the well were abandoned because the lack of hydrocarbon shows in the targeted zone. The well was abandoned with a temporary plug and re-entered' later in the drilling season to side track the original hole to attempt to find oil higher up the structure. Hole problems that were experienced in the first interval of the well consisted of high background gas encountered while drilling through hydrates. The gas hydrates drilled on this well did not cause adverse problems and was handled safely by the rig crews. Using gas background gas and resistivity data, there appear to be three separate zones that contain hydrates extending from 1,875'- 2,150', 2,400'-2,760', and 3,060'-3,150'. In the deviated section of the hole, the angle build and direction was performed adequately as only minor amounts of drag were experienced on trips. The probable causes for the drag were swelling clays and some wall cake buildup in sands. The short trips employed while drilling this section proved to be an adequate means to clean and condition the hole. The kick off point for this well was started in the first well bore interval below 300'. From here, the hole angle was gradually built to an average of 55-60 degrees and an azimuth of 235 +/- degrees by 2,850 ' This angle and direction was maintained until 8,600' were the angle was dropped to an average of 12 degrees by 9,900'. Good penetration rates were observed on this well with the proper use of rock and PDC type bits while drilling through a variety of different types of formations. One PDC bit was used to drill the entire 8 ½" interval - over 6,300' of formation. Slow penetration rates were experienced in the 6" hole interval and were due to mechanical factors related to the overbalance associated with the 12.2 ppg mud used in this section in conjunction with drilling shale estimated to contain 9.8 ppg pore pressure. Some minor hole problems were experienced in the 8 1/2" drilled section in the form of mud lost to the hole while cementing the 7" casing during the second stage cement job. Another notable problem was experienced and included trying to evaluate this section with wire line logs. The MDT and side wall coring tools would not go below 4,200' which was probably due to the high degree of hole angle. This was an area of the hole that recorded the maximum dog leg section of 4.75 degrees/100' and the maximum surveyed hole angle of 65.21 degrees taken at 4,327'. PORE PRESSURE: Pore pressure estimates for this well were made generally from observing overall mud gas readings relative to the current mud weight in conjunction with analysis of trend data established by resistivity data. "Dc" Exponent data for this well was inconclusive primarily because of the extensive use of PDC type bits. NWE 1-01 appeared to be near normally pressured extending from the surface to 5,000' TVD. Using the Condensed Resistivity Plot (refer to Section F) for reference, the beginning of an increasing pore pressure gradient is believed to start at 5,500' TVD. Pore pressure estimates were steadily raised to 9.4 ppg near the bottom of the Seabee Formation and to 9.6 ppg for the Torok. An estimate of 9.7 ppg was made for the HRZ and Kuparuk D Shale drilled between 6,350'-6,725' TVD. The Kupamk C Sand on this location was drilled with 12.2 ppg mud. This weight was chosen using offset data from nearby wells and applying the maximum case possible from data taken from production wells in the eastern Kupan~ Unit. Background gas and trip gas readings were very low drilling and coring through the entire Kupamk section and implied that the 12.2 ppg mud weight that was used probably supplied over .5 -1.0 ppg of overbalance. It is difficult to establish a pore pressure estimate using mud logging data for this zone when the mud weight used to drill exceeds this level of overbalance. RFT data from this zone taken after the completion of electric logs indicated that the Kupamk in this area had not been artificially charged. Pressure data from the C Sand suggested a formation pressure of about 10.2 ppg. ZONES OF INTEREST: Good shows of oil cut fluorescence were first noted on the mud logs from depths beginning around 3,410' in the Ugnu. These Shows lacked primary fluorescence color and intensity. Although high background readings were recorded in the Ugnu Sands, chromatograph breakdowns of trap line gas readings were predominately methane. This type of fluorescence, combined with relatively low recorded amounts of C2-C3 gases, indicated the presence of good quantities of heavy oil primarily in the top Ugnu Sands. Good shows of fluorescence were logged in the West Sak - Schrader Bluff beginning at 6,600' extending through individual sands to 7,450'. Sands logged in this zone had much better quality of primary fluorescence, high background gas readings, and very good ethane through pentane values from chromatograph analysis of the background gas. In our opinion, the presence of the observed good quantities of C2 - C5 is a good indicator that the oil in this zone has not undergone the same degree of bio-degradation as the oil found in the Ugnu. The West Sak - Schrader Bluff Sands on this well appeared to contain good quality oil, however data interpretation of the mud logs and gas ratio analysis suggest that porosity within this formation may be low. There were two zones that may have some reservoir potential extending from 6,600'-6,615' and 6,680'-6,735' The primary target for this well was the Kupm'uk C Sand. The better part of this sand was logged between 10,050'-10,090' with good porosity between 10,065'-10,090' indicated by the observed penetration rates. However, analysis of the gas readings and fluorescence from this zone indicated that the C Sand was predominately water bearing. Ratio analysis of chromatograph readings taken from steam still samples indicated that the zone contained minor amounts of residual oil.

reports for NWE 1-01. These reports are based on chromatograph evaluations of gases normally retrieved from mud samples injected into Sperry-Sun's Steam Still apparatus; consequently, interpretations made on each report reflect this procedure. The first two of the show reports in this report did not use a steam still apparatus to extract the gas for analysis and are so noted on the reports. Show reports are not always included in the well report analysis because of restricted information requirements placed on some wildcat wells. They do offer some insight of fluid content on potent/al producing zones of good permeability; however, they are often inadequate on tight zones or when mud-gas samples are taken while coring.

Formation Evaluation Hydrocarbon Ratios B.O. Pixler, SPE-AIME, Baroid Div. National Lead Co. Introduction Mud logging was first offered commercially in Aug., 1939. This logging method quieldy gained favor among many operators because the type of fluid in the formation could be determined within minutes after the formation was drilled. The presence and magni- tude of the methane show was and is the most im- portant factor in mud log interpretation. However this magnitude in some instances was improperly understood, and as a consequence some operators still do not use mud logging, even though the early technique frequently made the difference between a successful well and an abandoned hole. Both the "hot wire" log of gas combustibles in the sample and the percent-of-gas log obtained with the conventional gas trap and the gas chromatograph indicate only that the reservoir in question contains hydrocarbons. These methods do not necessarily indicate the quantitative amounts of the various hydrocarbons in the mud. The addition of a new Steam Still-Reflux gas sam- pling system to gas chromatography enables accurate determination of the composition of the mud gas sample. A knowledge of gas composition makes it possible to establish the relationship of methane to the heavier hydrocarbon shows. An awareness of this relationship led to a new, additional mud log inter- pretative technique that permits relating the quanti- tative amounts of methane (C~), ethane (C:), pro- pane (Ca), butane (C0, and pentane (C0 to in-place reservoir fluid content. by Analysis of A long-accepted premise is that as formations are drilled, the drilling mud filtrate partially flushes the formation fluid ahead of the bit. It was generally thought that the formations were flushed to an irre- ducible minimum- generally considered to be about 30 perEent of in-place fluid. Experience in mud log- ging, however, has shown that this rarely happens. This partial flushing does not prevent mud logging from successfully determining productive or non- productive formations. Experienced logging engi- neers, in possession of quantitative gas analyses, make interpretations that take into account the flushing that results in rocks of various permeabilities, the effect of overbalanced mud weight and the effect of initial filtrate loss. Method Ordinarily, when formation cuttings are drilled they retain much of the formation pore fluid. This fluid is released to the mud columa as the cuttings travel up the annulus. Most of the formation fluid in the cut- tings will be "produced" into the drilling mud during the top 500 ft of hole travel. Conventionally, a mud sample is diverted to a mechanically operated gas trap to obtain a sample of the gas in the mud. The effi- ciency of this trap is from 15 to 70 percent, depending upon the gel strength of the mud, the amount of mud flowing through the trap and the rotation speed of the trap impeller. The magnitude of the conventional' The ratio o/ methane to the heavier hydrocarbon components ~ ethane, propane, butane, and pentane - is indicative of gas, oil and water productive potential. The Steam Still-Reflux Unit, used in conjunction with mud logs and gas chromatographs yields a quantitative analysis from which this ratio can be plotted. gas show. is, therefore, quantitative only to the air-gas sample obtained. The sample is accurately analyzed by the ga~ chromatograph; but, because thc sample furnished by the conventional gas trap represents only a fraction of the gas present in the mud, and because that fraction is not representative of the total gases in the mud, the results are still only qualitative. When the Steam Still-Reflux Unit is used to obtain the gas sample, the gas sample will represent almost 100 percent of the hydrocarbon fxactions C~ through C~ that were in the mud sample. This enables the chromatograph analysis to be related quantitatively to the mud, and the readings to be reported as parts per million of each hydrocarbon vapor (C~ through C~) to mud volume. Because the cuttings from a particular formation "'produce'" the gas they contain into the drilling mud, it was reasonable to assume that this same formation, if completed, would produce gases of a.similar com- position. This assumption led to a comparison of ppm Logs of hydrocarbon vapors with similar data from producing wells. Plots were made of the ratio of methane to each of the heavier hydrocarbons fxom many analyses of wellhead samples. These plots were compared with plots, made from ppm Logs, of gas in mud. Both groups of plots showed definite patterns between (1) the magnitude of the ratios of methane to each of the heavier hydrocarbons, and (2) the slope of the lines of the plotted ratios. These, in mm, indicate productive potential and reservoir The Steam Still-Reflux Unit consists of a small steam boiler, mud-injection port, mud-steam mixing chamber, Reflux-Condensing Unit and a gas-extrac- tion port. Five ml of mud are injected into the purged mud-steam mixing chamber. The mud is rolled with 2,000 to 4,000 volumes of steam. The hydrocarbons (C, through Cs) extracted from the mud are collected at the Reflux-Condensing Unit, withdrawn with a syringe, diluted to the standard clxromatograph sam- ple size and injected into the chromatograph for analysis. The Reflux-Condensing Unit removes only the lighter paraffin series hydrocarbons from the mud sample tested. For example, if the mud contains diesel oil, the more complex hydrocarbons- CG and above --condense and drop back into the mud-steam mix- ing chamber. Therefore, regardless of whether the fluid phase of the mud is oil or water, the gas sample analyzed contains 'only the light fractions through Cs, and the analysis is representative of the formation gas. The full importance of determining formation gas composition has not always been apparent. At first it was observed that if the magnitude of butane in the mud was greater than the magnitude of either propane or ethane, the zone in question would pro- duce water and hydrocarbons. Later, the ratios of methane to each of the heavier hydrocarbon com- ponents were plotted on semilog paper. Hydrocarbon ratio plots obtained from ppm Logs and available data from wellhead gas sample analyses were com- pared. The comparison of the plots from ppm Logs and wellhead gas analysis data showed a striking cor- relation. The correlation demonstrated that ppm Logs made with Steam Still-Reflux samples could be in- terpreted in terms of in-place formation content. The magnitude of the methane-to-ethane ratio de-' term|nes if the reservoir contains gas or oil or if it is nonproductive. The slope of the line of the ratio plot of C~/C~, C~/C,, C~/C,, and C~/C8 indicates whether the reservoir will produce hydrocarbons or hydro- carbons and water. Positive line slopes indicate pro- duction; negative slopes indicate water-bearing for- mations. An undersaturated reservoir may show a negative slope, but such occurrences are rare. The ratio plots may not be definitive for low permeability zones, but unusually steep plots indicate tight zones.

The lower the C,/C... ratio, the richer the gas or the lower the oil gravity. If the ratio of C~/C.. is below about 2 or above about 65 the zone is nonproductive. Field Examples Fig. I shows average hydrocarbon ratio plots from limestone reservoirs in the Rocky Mountain area. Plot 1 is derived from analyses of gases from Mis- sissippian oil-producing reservoirs. The C,/C= ratio is 3.5. The slope of the line is positive and not steep. Plot 2 was obtained from analyses of gases from wells producing gas-condensate from the Silurian. The C,/C.. ratio is 12; the line slope is again positive and not steep. Plot 3 is from gas-condensate wells pro- ducing from the Ordovician. The C~/C.. ratio is 15 and, again, the slope of the line is not steep; all three plots show slopes favorable for production. 'Plot 4 shows ratios obtained from an analysis of gas from the Lower Ordovician, which produced gas and water. The plot shows a negative slope of the section from the C:/C~ ratio to the C,/Ca ratio. Many tests have verified the fact that if a ratio plot shows a negative slope, the zone in question is water-bearing. Fig. 2 shows plotted hydrocarbon ratios for pro- ductive reservoirs in South Texas. Plot 1 was made from an analysis of a wellhead sample of gas- condensate produced from a Frio sand, Hidalgo County. The production is rich in liquid hydrocar- bons as indicated by the low C:/C: ratio. Plot 2 is from an analysis of a wellhead gas sample from an l l,000-ft oil reservoir, North Lindsey field. The pentane was not reported, but the low C:/C: ratio indicates oil production. Plot 3 was obtained from a gas show at 12,690 ft on the ppi Log of the State Tract 49 No. 1 Well, Nueces County, Tex. Formation tests resulted in gas production. Experience shows that if the C~/C: ratio is above 65 the zone is too tight for commercial production. Fig. 3 shows the ratio plots obtained from ppi Logs on Texas Gulf Coast wells that were nonproductive in the zones of interest. Plot 1 is from the ppi Log of the R. A. Tally No. 1 Well, Victoria County, Tex. The C~/C.. ratio was 470. The zone was tested ex- tensively but it was a low permeability reservoir that could not be commercially completed. Plots 2 and 3 are from the State Tract 49 No. 1 Well, Nueces Count),, Tex. Plot 2 was from a sand encountered at about 8,060 ft. The relatively high ratios of C~/C2, C~/C.% C,/C,, and C~/Cs indicated that the zone was nonproductive because of the low permeability. This was subsequently verified by testing. Plot 3 was ob- tained from a sand at 9,130 ft. The negative slope of the ratio plot, C~/C., to C~/Ca, indicated that the zone was water-bearing. Subsequent formation tests showed water and non-commercial amounts of gas. Plot 4 was obtained from the ppi Log of the Kovar No. 1 Well, Victoria County, Tex. The sand encoun- tered from which the plot was made is at 10,120 ft. The gas show appeared to be good, but a negative slope of the C~/C, ratio to the C~/C4 ratio was posi- tive identification of a water-bearing formation. Evaluation Technique It is apparent that with this evaluation system, poten- tial production can be accurately predicted. The only significant time lapse between penetration of the formation and evaluation of its productive possibili- ties is the time required to pump the mud from the bottom of the hole to the surface and analyze it by the Steam Still-Reflux and Chromatograph method. Fig. 4 shows the evaluation technique, which may be described as follows. First, record the net increase of each gas com- ponent over the background gas; next, plot the ratios 4000 3000 · /. ...... 800! , 300 ...... 200 ...............

Application The ppm Log is only one of many totals that are ordinarily used for formation evaluation. But in many instances, the ppm Log has furnished the vital infor- marion necessary to make the final decision on a well. One well drilled in inland waters of Louisiana had what appeared on the ppm Log to be a good sand body, but the ppm Log showed only a nominal in- crease in gas. After the sand was penetrated and the well deepened, hole trouble was encountered. No other information of interest was available on the sand. The cost of the side-tracking to investigate the sand was sizable. Tight hole conditions and the low magnitude of the gas show indicated that the sand had good permeability and that possibly formation hydrocarbons had been flushed ahead of the bit. A plot of the hydrocarbon ratios indicated oil produc- tion. Therefore, at considerable expense, the sand was investigated and a new oil field was found. An interesting well recently drilled in St. Martin Parish, La., was the No. I St. Martin Bank and Trust located on the southeast flank of the Arise La Butte Dome. A good sand encountered at about 8,000 ft showed Oil, but the negative slope of the ratio plot indicated that the sand was water-beating. The well was deepened to approximately 9,600 ft. One of the partners, a successful independent with a talent for finding oil by "feel" and by prudent use of the latest technology, decided that the formations in which the well was being drilled were tilted to almost vertical.

The sand that was drilled at g,000 ft in the first hole was encountered in the directional hole at approximately 7,400 ft and the entire sand was hydrocarbon saturated. The ppm Log and the ratio plots from the sand in the sidetrack hole are shown in Fig. 5. Table 1 shows the mud gas components related to percent of total gas. In actual practice the ppm gas shows obtained from the ppm Log are not converted to percent of total gas; but note the general decrease in percent methane in the lower section of the sand compared with that in the upper section. The magnitude of the gas show in the straight hole and in the sidetrack hole was significant. An accurate determination, how- ever, of the composition of the gas in both cases led to correct conclusions on the potential productivity of the sand at the different depths in each hole. Note that the ratio Plot 1 at the top of the sand indicates a gas cap. As shown in Table 1, the gas was 93.1 percent methane. Subsequent plots indicated that production would be oil. In each of these cases the C~/C: ratio was less than 9. The lowest ratio, 4.5, is shown in Plot 6, which was made from the show at TABLE I~MUD GAS COMPONENTS, PERCENT OF TOTAL GAS Depth - (fi:) C, C: C, C, C.~ 7,460 93.1 3.6 1.5 1.2 0.6 7,475 82.4 9.6 5.9 1.4 0.7 7,485 74.4 13.3 10.0 1.6 0.7 7,490 78.0 11.4 8.6 1.4 0.6 7,500 77.0 14.3 7.2 1.1 0.4 7,515 76.1 17.1 5.! 1.4 0.3 the bottom of the sand.

Conclusions Only qualitative shows of hydrocarbons in the mud can be derived from conventional mud logs. I2 chromatography is used, only a general indication of in-place gas composition is obtainable. Such hydro- carbon shows may be reported as units of gas or percent hydrocarbons or parts per million of gas in thc air-gas mixture tested. Only the presence in rela- tive amounts, not the actual quantity, of hydrocar- bens in mud is indicated, and other supplemental information may be necessary to evaluate the forma- tion in terms of potential productivity. However, if the composition of the gas sample obtained from the mud is representative of the in-place formation gas, then the gas analysis is accurate. The use of the Steam Still-Reflux Unit makes possible a report of forma- tion gas composition on the ppm Log. Meaningful ratio plots of gas composition can then be made. Even though many factors affect the amount of reservoir fluid released to the drilling mud, reservoir potential productive capabilities can be determined by a study of the ratio of methane to each of the heavier hydro- carbon components. The hydrocarbon ratio plot is a unique technique and provides the operator with new information for evaluating productive possibilities of exploratory wells. Computer programs involving percent gas in mud (ppm Log) and gas composition are being used in special cases to determine reservoir potential produc- tion. The use of computers in mud log interpretation, although new, will contribute significantly towards a better application of the data. shown on the ppm Log. 3'PT Original manuscript received in Society of Petroleum Engineers office Aug. 5, 1968.

GUIDELINES FOR USI[NG PPM RATIO PLOTS TO EVALUATE HYRDROCARBON SHOWS ('REVISED 9/27/89 TO COVER "METHANE ONLY" SHOWS) A show that has only methane or primarily methane CAN be indicative of a productive zone. Many wells in the Gulf of Mexico produce only methane or methane and saltwater. CYhe commercial productivity of a GAS/SALTWATER well is based on the relative 'proportions of gas versus saltwater saturations determined by resistivity measurements.) a) Fill out a SHOW REPORT in a zone that meets the requirements of a show based on the definition even if it contains methane only. b) State in the LOGGER'S OPINION that this is a "methane only" show. c) Also state that C1 only CAN be indicative of dry-gas production BUT usually has saltwater associated with it. After making the ppm plot and observing for a neeative slope, checking for a chloride, increase (by titration or conductivity) OR observing a resistivity decrease on an MWD log, appropriately "X" the .GAS or .GAS' and WATER indication in the ZONE PRODUC'IXON ANALYSIS paragraph on page 1, including the depth of the water contact if detectable and the footage of the show. C1/C2 between 2 and 15 indicates OIL. You should see some fluorescence in the mud or cuttings but not necessarily. a) -.Values in the range of 2 -4 indicate Iow gravity oil (10- 15 on the API gravity comparison scale.) A low gravity oil can have a bronze, brown or dull orange fluorescence and be very dark brown to black in color. b) Values in the range of 4-- 8 indicate medium gravity oil (15 - 35 on the APl gravity comparison scale.) A medium gravity oil will have a cream to bright yellow fluorescence and be light to medium brown in color. c) Values in the range of 8 - 15 indicate high gravity oil (35+ on the APT gravity comparison scale.) A high gravity oil will have bright blue to blue-white fl. uorescence and be clear in color. SEE NOTE BELOW. C1/C2 ratios in the 15 to 65 range indicate GAS. Any fluorescence associated with a GAS zone indicates the presence of condensate. SEE NOTE BELOW. a) Values in the 15 - 20 range indicates gas rich in heavies, C4 and C5 ppms, and would most likely be associated with condensate. b) Values in the 20 - 50 range indicates gas rich in mid ranged hydrocarbons, C°_ and C.3 ppms. NOTE: ., e c) Values in the 50 - 65 range indicates gas rich in the lighter fraction, C1 ppms. Cl/C2 ratios in the i0 - 20 range ca_.gn indicate the presence of CONDENSATE or DISTILLATE. Indications would be the presence of bright yellow or blue white fluorescence OR cut. (Condensate is a hydrocarbon that is a GAS under the temperatures and pressures of the reservoir but "condenses" to a LIQUID when it reaches the surface. It would compare to gasoline in appearance and physical characteristics and was in fact called "drip gas" in the early oilfield. Ci/C2 ratios less than 2 and greater than 65 indicate NON-PRODUCIBLE HYDROC~ONS. a) A hydrocarbon with a value less than 2 indicates an OIL with a gravity so low (the oil is very thick) that it can't be produced. b) A hydrocarbon with a value greater than 65 indicates a light GAS, mostly C1, but the low permeability nature of the formation makes it non- producible. The slope of the line of all plotted ratios indicates if the zone will produce hydrocarbons only OR hydrocarbons and water. Line slope also provides some indication as to the formation permeability. a) An ~all nositive slope, up and to the right, indicate HYDROC~ONS ONLY. b) If an.v. of the line segments have a negative slope, down and to the right, .HYDROCARBONS AND SALTWATER is indicated. Obviously, the mud chlorides SHOULD increase but not necessarily. A steep line slope indicates reduced permeability AND the steeper the slope, the lower the permeability. Steep is a relative term BUT the dashed lines separating the GAS, OIL and NON-PRODUCIBLE areas of the graph are there for comparison. OIL plots whose line slope is somewhat steener than the MIDDLE dashed line indicate low perme, abilitv. OIL plots whose line slope is equal to or less than the MIDDLE dashed line indicate _good l~ermeabilitv. _ GAS plots whose line slope is s_omewhat steet~er than the TOP dashed line indicate Iow permeability. __ GAS plots whose line slope is equal to or less than the TOP dashed line indicate ~ood p.e,rmeabilitv.

SUBJECT: Petroleum Inspector E9NJBJFE.DOC Diverter Test, Nabors 18E BPX exploratory NEW 1-01 Sec 34, T12N, R11E, UM PTD #98-0013 Tuesday, February 10, 1998; I witnessed the Diverter function test on Nabors rig 18E preparing to spud BPX exploratory well NWE 1-01. I arrived to find the rig ready to test but still hooking up the panic lines. I made a cursory tour of the rig and its surrounding area and found all to be in good shape except that the 10" vent lines needed to be tied down. The general direction of the primary vent line was pointed in a direction that if used might cut off access or egress of the ice road to the pad. The alternate flare route could be used to allow escape if needed. On future wells I would suggest that more thought be placed on pad and ice road layout. The function test, went well with closure time on the 20" annular of 50 seconds which is about average for this size equipment. I observed the proper sequence of closure with the vent line valve. The accumulator recharge time of 1 minute 40 seconds was adequate. The gas detectors were in need of calibration and would be done before spudding. SUMMARY: The Diverter function test I witnessed on Nabors rig 18E went well with two failures observed.

Diverter, BOPE and mud fluid system schematics will be provided when determining rig (rig will be in the current fleet of north slope rigs and the schematics should therefore be on file with AOGCC). The Kuparuk reservoir will be drilled under the assumption that it is at the abnormal pore pressure of 0.62 psi/ft or 11.9 ppg EMW. Maximum anticipated bottom hole pressure is 4108 psi at 6640'TVDss. Maximum anticipated surface pressure assuming gas in entire annulus (0.1 ppg) is 3444 psi. Hazards · Ugnu may be slightly overpressure due to water disposal at GC-2 which is 10.5 miles to the east. · Two faults are present within the planned wellbore projection. These faults will be discussed within the well plan and measures will be taken to control lost circulation or other problems associated with drilling across the faults. · Based on offset well data, there are known accumulations of frozen gas hydrates in the area. (See attached discussion). The Kuparuk interval is potentially overpressured due to gas injection in the Kuparuk Operating Unit. Recent well data suggests that a pore pressure of 0.62 psi/ft is possible. Disposal Cuttings should be hauled to the ball mill at CC-2A. Fluid Handling: Haul all drilling and completion fluids and other class II wastes to CC-2A for injection. Haul all Class I wastes to Pad 3 for disposal.

Once ice construction is completed, an IPA drilling rig (currently unsure which rig will drill 1-01 I) will move out to the ice pad via an ice road departing the Spine road and rig up on well NWE 1-01. The rig will be placed on rig mats and herculite. Drilling Operations: (All depths are approximate) The ice pad will be constructed and a well cellar excavated before the rig arrives on location. The conductor hole will be pre-drilled and the 20" conductor set and cemented before the rig's arrival and while the camp is set up. Move in, rig up. Accept rig for operations. Nipple up diverter and function test same. The well will be drilled as a S-shape wellbore. The 12-1/4" hole section will be directionally drilled from 400'md and will contain a gradual build section in order to line out to a ,-,59° tangent angle at the surface casing point at 4055' MD. Run and cement 9-5/8", 40# casing to surface utilizing a two-stage cementing equipment. Install blowout prevention equipment consisting of 5,000 psi W.P. pipe rams, blind rams, and 5,000psi annular preventer. Test BOP's. Maximum anticipated possible reservoir pressure is 4108 psi (11.9 ppg EMW) at 6640' TVDss. Maximum possible surface pressure is 3444 psi based on a gas column to surface from 6640' TVDss. Mud logging facilities and operations will be on location and functional from spud to TD of the well. Formation leak-off tests will be performed 20' below the 9-5/8" and 7" casing shoes. In addition a 'jug' formation test will be performed prior to drilling into the Kuparuk D shale. The 7" hole section will be drilled tangent to ,-,8140'md and then will begin a 3°/100 drop section in order to position the well vertically before coring the Kuparuk C interval. A formation 'jug' test will be performed prior to reaching the Kuparuk D interval in order to verify the integrity of the intermediate formations drilled. If the 'jug' test results in a formation integrity to provide sufficient well control kick tolerance then the intermediate section will be drilled to the base of the Kuparuk D shales and then the Kuparuk C sands will be cored with an 8-1/2" hole size (Longstring Design). However, if the 'jug' test shows inadequate formation integrity - the 7" casing will be top set above the Kuparuk D shale and the next hole section will be drilled with a smaller hole size. The logging sweep in the intermediate hole section will include the platform express and dipole sonic. Side Wall Cores will also be obtained if hydrocarbons are observed while drilling this hole section. Run and cement 7", 26# L-80 casing as per the jug test results bringing top of cement to 1000' above the top Kuparuk. Drill a vertical 6" hole to TD. Run logs (platform express, dipole sonic, CMR, RFTs, FMS) on eline. Clean out hole. Run and cement 4-1/2" liner. Run 3-1/2" completion string. The well is planned to be tested after the rig is moved off of the well. The well is planned to be suspended with the completion string left in the wellbore. If the well is abandoned, the appropriate plugs and markers according to AOGCC regulations will be met. The pad will be cleaned up of any surface debris. BP EXPLORATION To: Bob Crandall From: Greg West Subject: Date: 1/19/97 Shallow Gas Hazards on North West Eileen 1-01 Appraisal Well Based on review of a seismic traverse line that includes analogue wells Arco NW Eileen St #1, Mobil West Kuparuk St #1, and Socal 33-29E, no shallow gas pockets are expected on the North West Eileen 1-01 well· No seismic anomalies were seen at any of the three analogue wells or at the proposed ice pad NWE 1. However, the North West Eileen area does not have any high resolution seismic and offset data will therefore be used as the primary source to evaluate potential drilling hazards which could include shallow gas and/or hydrates. · ,;~ ; ~ Based on review of offset drilling data, the F~eR~I to encounter hydrates while drilling surface hole at NWE 1-01~h. Review of off-set well data reveals presence of hydrates near the base of the permafrost. The offset wells reviewed include Mobil West Kuparuk State #1, NW Eileen State #1 & #2, West Sak 24, KRU lC-12, Prudhoe Bay Z pad, and Milne Point K pad. When a hydrate zone is encountered, the relative warmth of the drilling mud will decompose the hydrates and gasify the mud. The hydrates adjacent to the wellbore will continue to decompose and gasify the drilling mud as long as drilling operations continue to introduce heat into the hydrate-bearing interval. While encountering shallow hydrates has been known to cause severe problems in other parts of the world, this occurrence is well known and handled frequently at Prudhoe Z-Pad and Milne Point. The use of high density mud weight (,-.10.2 ppg) and the additive Lecithin, are two proactive safety measures that will be employed in the drilling operation. Data from off-set wells shows gas hydrates to most likely exist at the base of the permafrost in several layers beginning at 1500' tvd to 2450' tvd with a total thickness of 171' to 349'. The base of the permafrost in NWE 1-01 is expected to be ,..2200' tvdss. Operating procedure will be to add Lecithin to the drilling fluid when gas cut mud is found by the mud logger. The mud weight will continually increase from 8.6 ppg at spud to 10.2 ppg at ,--1600' tvd and remain so until surface hole TD. These actions continually prove to be sufficient when gas hydrates are encountered at Milne Point and Prudhoe Z-Pad. The drilling rig for NWE 1-01 will also be equipped with the following gas detection systems as a proactive measure to monitor shallow gas and/or hydrates: · Rig gas sensors located at the pits, cellar, & rig floor · PVT system · Trip tank · Well Mud Loggers North West Eileen 1-01 - Shallow Gas Hazards - Specialized personnel - Total Hydrocarbon Analyzer (FID) - Gas Chromatogragh (FID) Usual SSD procedures will be followed to minimize any potential for a shallow gas kick. Sufficient hydrostatic column will always be maintained while drilling the well and the correct tripping procedures will be followed while tripping in and out of the hole. If a shallow gas kick is taken prior to setting surface casing, the gas kick will not be shut-in, but diverted through the diverter system. If you have any questions, please give me a call at 564-4803. North West Eileen 1-01 - Shallow Gas Hazards 2 North West Eileen 1-01 Pore Pressure / Fracture Gradients · Pore Pressure ~,.~0il &..".;as c0~-~s, u0~,::~.~! Review of seismic dat~ in the vicinit~ of North West Eileen 1-01 (NWE 1-01) in conjunction with offset well records (mud logs, sonic logs) has indicated thst no abnormal pressures are expected in the ~WE 1-01 area ~side from the Ugnu which has potenti~ll~ been charged from produced water injection and the Kuparuk C sand interval which has potentially been overcharged from gas injection in the Kuparuk River Operating Unit. The Ugnu sands are charged in many parts of Prudhoe Bay and the pore pressure is expected to be ,-,9.0-9.2 ppg in that interval. An abnormal pressure of 0.62 psi/ft or 11.9 ppg EMW is potential in the Kuparuk C sand interval due to gas injection. The over-pressure gradient originates from the Kuparuk River Unit gas injection strategy which originates at DS I-C. This overpressure was confirmed most recently in the 1C-12 well drilled by the Arco Kuparuk drilling group. The abnormal pore pressure may be baffled by two significant faults which are located to the west of the NWE 1-01 bottom hole location; however SSD will plan the well assuming the abnormal gradient mentioned above. Mud weights which provide 100-200 psi overbalance will be used to ensure hydrostatic control. The well is planned to TD at the top of the Miluveach or base Kuparuk. · Fracture Gradient Information available from the offset wells have been reviewed to provide a best estimate of fracture gradients to be expected. 9-5/8" casing point (,-,2710'TVDss) should provide a fracture gradient of 12.2- 13.5 ppg EMW. This leak off result will provide sufficient kick tolerance to drill to planned TD of the 8-1/2" hole section in the Kuparuk D shale at ,-,6615'TVDss. Fracture Gradient at the 7" shoe will be approximately 13.0 - 14.5 ppg EMW, sufficient to drill to the planned TD of 7450'TVDss. · Kick tolerance monitoring and pore pressure determination techniques Kick tolerance volume will be continually updated as the well is in progress, incorporating the most up-to-date data available from the well. The real-time resistivity log incorporated in the MWD assembly will enhance the mud logging crew's ability to monitor for change in pore pressure in addition to the normal techniques of D-Exp. projections, cuttings quality, connection gases etc. North West Eileen 1-01 Anticipated Pore Pressure/Mud Weight/Fracture Gradient 1000 20O0 3000 4000 5000 6000 7O0O 8O0O ppg EMW 8 9 10 11 12 13 14 15 ~aise Mud'~,.'eig hi ~, ~// F°r HydrateS;~':~ ~ Max Frac Grad '.~.
