Fax (907) 344-2823 INTRODUCTION Core Laboratories was requested to perform a sidewall core analysis study on behalf of ARCO Alaska, Inc. for samples recovered from the Colville River #1 Well. Presented herein are the results of this study. Rotary sidewall cores were submitted. A service description with methodology is presented in section 1. The sidewall core analysis results are presented in section 2. Section 3 contains shipping transmittals. We sincerely appreciate this opportunity to be of service and hope these data prove beneficial in your exploration efforts. TABLE OF CONTENTS Section 1 SIDEWALL CORE ANALYSIS, SERVICE DESCRIPTION AND METHODOLOGY SIDEWALL CORE ANALYSIS, TABULAR RESULTS TRANSMITTALS SIDEWALL CORE ANALYSIS SERVICE DESCRIPTION AND METHODOLOGY SECTION 1 SIDEWALL CORE Fi el d Procedures Core Laboratories was not represented at the wellsite. Twenty rotary sidewall samples were sent by air freight to Core Laboratories' Anchorage facility in April of 1993. The rotary sidewalls were preserved in sidewall glass jars. Core Processing Sample Preparation Dean-Stark Sidewall Samples Eighteen samples were selected for Dean-Stark analysis. Two samples failed in the permeameter. They were first cleaned of drilling mud and cut into shapes approximating right cylinders dry. The samples were then weighed, placed in thimbles, and loaded into the Dean Stark. Analysis Techniques Dean-Stark Fluid Saturation Measurements Water was extracted from the sidewall samples by Dean-Stark technique using toluene. Samples were left in Dean-Stark for 24 hours. Recovered waters were measured and the samples were placed in a Dean-Stark with chloroform for hydrocarbon extraction for a minimum of 48 hours. Extracted samples were dried in a convection oven at 240 degrees F. for a minimum of 24 hours, and cooled in a desiccator to room temperature before porosity and permeability were measured. Saturations by Dean-Stark methods were calculated using Equations 1 and 2. So : [((W1 - W2 - H20)/Do)/Vp] x 100 Sw : [H20/Vp] x 100 (1) (2) Where: So = Oil Saturations, Percent Sw = Water Saturation, Percent W1 = Natural Weight W2 : Extracted and Dried Weight H20 : Extracted Water, Density Assumed 1.0 gm/cc Do : Density of Oil Vp : Pore Volume Grain Density Grain volume determinations were performed according to Boyle~s Law utilizing the Helium Porosimeter. Grain density was calculated using Equation 3. Dg : Mg/Vg (3) Where: Dg = Grain Density Vg = Grain Volume Mg = Grain Mass Atmospheric Porosity The samples were measured for bulk volume by mercury displacement at ambient conditions. Porosity was calculated using Equation 4. P : [(Vb-Vg) / Vb)] x 100 (4) Where: P: Porosity, Percent Vb = Bulk Volume V9 = Grain Volume Atmospheric Permeability to Air Samples were loaded into a Hassler type core holder at a confining pressure of 400 psig. Permeability calculations were performed as defined by Darcy~s Equation for compressible fluids, Equation 6. Pa x v x 1000 Qa x L x L K - x (6) (P1 - P2)(P1 +P2) 2 Vb Where: K = Permeability v = Gas Viscosity P1 - P2 = Differential Pressure P1 + P2 = Mean Pressure Pa = Atmospheric Pressure Qa = F1 ow Rate L = Length Vb : Bulk Volume Sample Disposition The sidewall samples are at Core Laboratories Anchorage office, and will be sent to Bayview shortly.

A cement retainer had been set at 200' before I arrived at the location, and the BOP stack had been removed. Th~ open-ended 5 1/2" DP was run in the hole to the cement retainer. Fresh water~'v~~e DP to flush the mud out of the 9 5/9" closing. A cement slurry consisting of 95 sks of Class C -- 16 bbls @ 15.6#/gal -- was pumped down the DP and circulated back to the surface with good cement returns. I told G.W. Craig to be sure to cut the casing off 3' minimum before the tundra level before installing the marker post. Saturday, April 10, 1993: I was contacted by G.W. Craig, Arco rep, informing me that he was going to cut the casing off on Colville River #1 and install the P&A marker. I went to the location and checked the cement in the casing strings. The cement was 6" below the top of the casing when the final cut was made. As the attached pictures show, this was filled up, the plate was welded on, and the marker post was then welded off to the plate and the hole was backfilled. The casing was cut off 3'+ below the tundra before the plate was welded on. The information on the marker post does not coincide with the PTD information. The location was moved due to the original location being in a lake. AAI should send a sundry notice with an as-built drawing. attachments STATE OF ALASKA ALASKA OIL AND GAS CONSERVATION COMMISSION Surface Abandonment / Location Clearance Report ( Title 20 AAC 25, Article 2 ) .......... i ........................................ i il i ......... .

When I arrived, the plug had already been pumped and the rig was waiting for the cement to harden (12-hour cure). An attempt was made to tag the plug and was unsuccessful -- the cement was not set up sufficiently. We waited an additional six hours to no avail. By all appearances, the cement had gotten contaminated. The old cement was circulated out and new cement was pumped. I left location at this time.

Johnston, Chairman Alaska Oil and Gas Conservation Commission 3001 Porcupine Drive Anchorage, Alaska 99501-3192 Re: Application for Sundry Approval ARCO Colville River #1 Dear Commissioner Johnston, ARCO Alaska, Inc. hereby requests approval of a change in the length of conductor casing in and the method of abandonment of the ARCO Colville River #1. The conductor is currently permitted for setting at 120' below pad grade and the well to be abandoned 20' below ground level. ARCO would like to modify the conductor setting depth to 80' below pad grade and the abandonment plan to leave the well abandoned as a typical onshore well. Our Application for Permit to Drill this well inadvertently treated this well as one to be drilled in the active delta of the Colville River. In it, we specified a 120' setting depth for the conductor and a subsurface abandoment. This well is in fact located on stable tundra approximately two miles east of the Colville River and should have been proposed as an onshore well with an 80' conductor and an abandonment at ground level with a well marker as required in 20 AAC 25.120. Both of the two nearest offsetting wells, the Union Kookpik #1 and the ARCO Fiord #1, indicate there are no adverse hole or pressure conditions to demonstrate a need to set the conductor any deeper than 80'. If you have questions or require additional information, please contact Bill Penrose at 263-4511 or myself at 263-4962 in our Anchorage office. Sincerely, A.

Johnston, Chairman Alaska Oil and Gas Conservation Commission 3001 Porcupine Drive Anchorage, Alaska 99501-3192 Re: Application for Permit to Drill ARCO Colville River #1 Dear Commissioner Johnston, Attached is ARCO Alaska, Inc.'s application for a Permit to Drill an onshore exploratory well, the ARCO Colville River #1, on State lands near the mouth of the Colville River. The proposed well location is approximately 8 miles south of the ARCO Fiord #1. The wellsite will be accessed by way of an ice road extending westward from Kuparuk Drill Site 3H. ARCO plans to use Rowan Drilling Company's Rig 33 to drill this well from an ice pad during the winter of 1992-93. Attached find the information required by 20 AAC 25.005(c) and 20 AAC 25.061. All waste drilling mud and cuttings generated dudng the ddlling of Colville River #1 will be hauled to the Kuparuk River Field for temporary storage and eventual processing by a ball mill that will grind the cuttings prior to their being injected down an approved Class II disposal well. The TD of this well will be at the base of the Nuiqsut Formation that directly underlies the Kuparuk Formation. H2S has not been encountered in this region in any stratum shallower than the Lisburne Formation. Therefore, ARCO has not included an H2S contingency plan with this application. However, all ddlling mud, cores and produced fluids exiting the wellbore will be monitored for detectable levels of H2S. The Commission is requested to keep confidential the following attachments to this permit application that are drawn from research and data proprietary to ARCO Alaska, Inc.: Pressure Information Proposed Drilling Fluid Program Pressure Analysis Proposed Drilling Program ARCO Alaska, [nc. is a Subsidiary of AtlanticRichfieldCompany /',i~ -!', i,.-' (; PROPOSED DRILLING PROGRAM ARCO Colville River #1 (Per 20 AAC 25.005(c)(10)) Application for Permit to Drill Colville River #1 . . . . . , . . . 10. 11. 12. 13. 14. 15. 16.

The analysis was performed using ARCO's "GAS" (Geopressure Analysis System) software. Figure 1 shows the existing well data used to determine the regional compaction trend. The coefficients for this compaction trend are listed in the appendix. The offset well sonic data is then converted to mud weight equivalents using another equation called the 'pressure translation gradient'. This is compared to the existing mud weight data from the offset well. The coefficients of the pressure translation gradient are reworked until a close match is obtained between the mud weight actually used and the calculated mud weights from the sonic values. This step is called the well calibration phase and the results are shown in Figure 2. The actual coefficients used are detailed in the appendix. The seismic data is incorporated in the form of detailed velocity analyses around the proposed well site. The velocity analyses are converted to interval transit time (ITT) both in time (Figure 3) and in depth (Figure 4), and then converted to mud weight equivalents using the same coefficients derived from the offset well data. Figures 5 and 6 detail this mud weight equivalent data both in time and in depth. The actual seismic velocity functions used are listed in the appendix. For this well the seismic line used was WKE92-14 and the well location is at SP 1660 CDP 3318. The proposed well is a planned straight hole so no deviation information was used. Seismic velocities were calculated across CDPs 3302 to 334O. The geopressure analysis shows a slight anomaly beginning at approximately 3,000'. This is due to a small decrease in RMS velocity centered about 800 ms in time. This manifests itself as a possible geopressure zone. From the surface to 3,000' the mud weight shows a normal gradient pattern, going from approximately 9.0 ppg to 9.8 ppg at 3,000'. At 3,000' there is an abrupt increase to approximately 10.5 ppg at 3,200'. It stays constant at 10.5 ppg down to 3,900', where it drops back to 10.0 ppg, and then trends back to 9.0 ppg by 4,800'. It again kicks out at about 6,400' to a pressure equivalent of 9.7 ppg and then slowly increases to about 10.0 ppg at the expected TD of 7,300'. This is shown on the color plots and on the single trace extraction at the well site (Figure 7). Additionally, seismic velocity (ITT vs. depth) at the proposed well site is shown in Figure 8. This data shows a possibility of a geopressure Application for Permit to Drill Colville River #1 zone centered about 3,500'. Currently, we have no other reason for this behavior of the seismic velocities, other than a slight over pressured zone. Also attached is a summary plot which shows anticipated pore pressure, mud weight and fracture gradient curves. The fracture gradient is derived from leak- off tests conducted last year in the ARCO Fiord #1 and ARCO Kalubik #1 wells. In addition, other data was gathered from pressure integrity tests conducted by other operators on wells in the Colville Delta. Application for Permit to Drill Colville River #1 APPENDIX Compaction Trend The compaction trend is expressed as a linear function' y=a+bz For this project the coefficients are: a = 2.24463 b = -4.909665e-05 Pressure Translation Function Within the GAS system the user may define the pressure translation function, to better match the existing pressure data as described by the mud weights used in the offset well. This function is described by the 3rd order polynomial: y: at + x( a2 +x (a3 + a4x)) For this project the coefficients are: al = 0.51 a2 = 5.093 e-04 a3 = 4.33 e-05 a4 = 0.0 Application for Permit to Drill Colville River #1 I ~' I1' ' ' I II I III I'1 '1 I II I1'"'1 ~11'1 Coiville River #1 input data (Fiord #1) D 1000 400{) 5000 6000 '?000 Figure Colville River #1 Well Calibration (Fiord #1) SUF ['RESS ,?~VG bk, NI~ TRANSIT TIME DERI.,,EE MI'ID WEIGHT 1008. 2000. 3( 00. ,:!000.

All tight hole should be reamed. Pit volumes should be monitored and all solids control equipment should be turned off. The hole fill should be monitored on each trip to insure exact fluid displacement. 6.) Maximum utilization of solids control equipment is recommended throughout the surface hole drilling operations.

Treatments with PAC/Drispac polymers should be used throughout this section of the hole to control the API fluid loss in the 8 to 10 cc range or as required based on actual well bore conditions. Low viscosity or high viscosity PAC/Drispac products (PAC-L/PAC-R ~ Drispac SL/Drispac R) are available for which ever application is appropriate. 5.~ Control excessive theological conditions with additions of Therma-Thin on an as needed basis. Therma-Thin is an effective polymer deflocculant designed to provide effective theological stabilization. Additions of Desco-CF may be required to control excessive gel strengths and should be used moderately on an as needed basis. 6.) It is recommended to make additions of prehydrated Aquagel to improve filter cake quality and aid in the control of the API fluid loss. The commercial bentonite content should be maint~ned in the 2 to 6 ppb range. Additional Aquagel additions may be considered as hole conditions dictate. 7.) Maintain the pH in the 9.0 to 9.5 range with additions of Caustic Soda. Note: Caustic Soda should be used in the Aquagel prehydration process to increase the pH in the range of 9.0 . 8.) Utilize all solids control equipment for maximum solids removal.

GPM liP:..__ Bb Memorandum S[a[e of A]aska Oil and {]as Conservation Commission To: Russ Douglass / Fro: Jack Hartz December 30, 1992 Subj: Big Bend #1 Request for Exception to Diverter Line Bifurcation The ARCO request for exception to 20 ACC 25.035 (b) 1 is predicated on design and performance of diversion equipment on the Cirque #1 blowout and the impact of the failed diverter line on subsequent operations. The blowout illustrates the need to provide diversion away from the rig for the purpose of evacuating personnel from the rig, camp or well pad. The direction of diversion had no bearing on the subsequent operations because of diverter line erosion failures within the substructure and doWnstream of virtually every directional change feature in the line. There were no apparent failures of target tees. Perhaps'this suggests that maintaining integrity of divert line to a point away from the rig is paramount and bifurcation is only useful if it can be accomplished at a point a reasonable distance away from the rig or ignition sources. The API Recommended Practice, RP 64 July 1 1991, does not require as a standard practice, multi directional diversion of well fluids during diversion operations. They state a single vent line downwind from the rig and facilities is typically used. API suggests that operators may want to have vent lines go in 2 directions to allow for changes in prevailing winds. Within the same RP they cite offshore platforms where one diverter line is used due to prevailing winds. ARCO's request falls within the range of API guidelines as stated in RP 64. The AOGCC regulation allows the Commission discretion to approve variances or exceptions to the requirements spelled out in 20 ACC 25.035 (b) 1. The requirement to bifurcate the vent line is an attempt to allow for wind direction changes and appears to add flexibility to the system. In the case of Cirque #1, the diverter line erosion failure negated the diverter system's fundamental utility and no flexibility was attained. Integrity of the diverter line and associated equipment appears to be the most critical factor in safe operations of the diverter equipment. Page 2 1992 Reserves Estimate Diverter line size plays a critical role in diversion operations. Flexibility, while an ideal situation may in fact lead to false security and cause operational difficulty. An article in Oil and Gas Journal, Dec.2, 1991 (enclosed) cites size and straight runs as primary considerations for diverter system design. For example a size increase from 10"(minimum size in 20 ACC 25.035 (b) 1) to 16" diameter increases cross sectional flow area from 79 to 200 square inches and thereby decreases velocity by a factor of 2.6 . The authors indicate that halving velocity will decrease the erosional wear rate by a factor of 6. Wind data analysis and the Focus model results would appe. ar to indicate that gas velocity will overcome wind forces and disperse the gas to less than the LEL before it returns to the diverter vent outlet for those cases studied. In a conversation with M.Winfree, he indicated the momentum jet dispersion model is in common use in facilities design. I have no experience with it and cannot judge the results. Conceptually, it sounds reasonable and serves to strengthen ARCO's case. Given the experience at Cirque #1, bifurcation will cause failure of the diverter line under conditions of gas/sand mixture flows because of the directional change. One issue is placing the failure point a safe distance from ignition sources. In this case as well as in the regulation, 100' is the minimum distance. The next argument is why require a feature which will cause a failure? I believe the steps taken to avoid uncontrolled flows, kicks and blowouts which ARCO has identified and are apparently incorporating into their procedures are far more important than bifurcation. In the absence of compelling evidence to the contrary, I don't support mandatory bifurcation of the diverter line. I believe the Commission should favorably consider the request and perhaps consider rewriting the regulation with these size and straight line features in mind. In the future, it would be advantageous to discuss with industry the advantages and disadvantages of different diverter configurations and resolve to a mutually beneficial system. Larger diverte, safer for shallow gas control David Mills Glasgow Polytechnic Glasgow, Scotland Einar Dyhr Copeman Engineering Copenhagen, Denmark Reducing the back pressure buildup on the wellhead during shallow gas control minimizes the risk of the gas broaching the seabed around the con- ductor pipe. This allows for an orderly procedure to divert the gas. Most diverter systems cause the gas/sand mixture to approach critical velocity, re- Suiting in extreme wear and short life expectancy of the surface piping. Calculations based on standard drilling pro- grams indicate that only a few existing diveder systems can handle a sizeable volume of shallow gas without creating excess back pressure on the wellhead. During the past 10 years six jack up rigs have been totally destroyed by shallow gas blowouts. Estimates for the to- tal losses sustained by oil companies and drilling con- tractors from these accidents has been well over $1 billion. The following cause the most severe damage from shallow gas blowouts: · Erosion of the seabed and possible cratering of the 'rig from gas around the conduc- tor pipe · Wear on the diverter sys- tem from the high velocity gas- /sand mixture, with possible fire threat to the dg. The diverter systems most commonly used on jack up dgs have flow capacities inad- equate to dived large volumes of gas from a large shallow gas reservoir without building excessive back pressure in the well. The large pressure buildup may subsequently fracture the formation at the conductor casing shoe. If the well is flowed, the diverter pipe will act as a long choke, causing the gas/sand Fig. 1 Schematic of well with 16-in. diveder ' ...i,"; :;:i .... 4./.:. !.6'In' dlverter line : . ..... -~. -,.:., '-'-' 'v;: 40-ff long -- ' · ' Dlverter / [ I housing . ~.~ Variable - ' - I ~_~ Pressure reading, P2~ ' choke : --': ~ I II2°f~''' ':'~ ~L~ ! ~i) Pressure ~eading, P1 Water line 84 it RKB at ~- Mud line at 224 ft RKB -~ 36-in. casing shoe at 550 ft RKB 26-1n. open hole Shallow gas formation at 1,475 It RKB mixture to reach critical speed. This, in turn, will cause the diverter pipe to wear down in a matter of minutes, resulting in a gas fire hazard below the drill floor. Several industry studies have pointed out the problems associated with excessively long or small diameter pipe used for diverting the gas overboard. Following the West Vanguard accident in Norway, Statoil investigated new ways to extend the service life of the p~ping system. Some sugges- .tions included the hardfacing of pipes and bends as well as testing of a variable choke mounted on the overboard end of the diverter pipe. The latest rig design in_the Norwegian North Sea requires a minimum diameter of 16 in. -for diverter lines, which should run overbSard p"'5~'s-~l~. On a Norsk Hydro ~in the North Sea, the diverter line diameter has been increased to 16 in., and a fixed choke with an ID of 12 in. has been mounted on the overboard end. These changes result in a reduced velocity through the diverter,s Outside Norway the most common diveder pipe diame- ters are between 8 and 12 in. Oil companies, rig design- ers, and drilling contractors have indicated a need to de- velop design criteria for shal- Iow gas surface equipment. :T~n criteria include a minimum ga_s_. ~15~"!..~.~_ .of excessive back pressure bu-[i~'~'~ and 'b~l~-ula"lFO-ds s' oh"'5~~e expected life of the surface system while flow- ing a gas/sand mixture.

This pressure dif- ference provides the driving force for the gas flow, and equilibrium conditions prevail if it is balanced by the gas flow resistance. It is possible to cal- culate with accuracy the gas flow rate and the resulting pressure and velocity profiles for any '_'iven drilling program and surface pipe system. As a result of the turbulence and the high gas velocity at the wellhead, padicles of sand may be carried in suspension by the gas. Gas velocities will not have to be high to convey sand vertically, padicularly if the gas is pressurized. The pressure gradient of the flow increases as the concen- tration of sand in the gas in- creases. Steady state condi- tigris also prevail in this situa- tion. For a given pressure drop, however, the rate of gas flow decreases with an increase in sand concentration. It is also possible to calculate the pres- sure and velocity profiles for gas/sand suspension flows. However, the result depends on the concentration of the sand in the gas, and this may dot be known With any certain- ty. The concentration of sand may also change with respect to time, further complicating the problem. Pipe surfaces erode rapidly with the increasing sand im- paction. The rate of erosive wear depends on the surface material, the impact geometry, the sand, and the flow condi- tions.

Flow central The pressure gradient in- creases with the increase in sand concentration; for a giv- en system pressure drop, the gas flow rate, and hence ye- Iocity, falls. The net effect of reduction in velocity and in- crease in concentration does not result in a significant change in the wear rate. To reduce the wear rate, both the velocity and sand concentra- tion must drop. This can be achieved through the use of an artificial resistance in the flow, or a choking mechanism. The best location for a 'choke is at the very end of the diverter (the location of gas discharge to the atmosphere). The use of a variable choke on the diverter makes it possi- ble to control the flow para- meters, further reducing wear to the diverter system. Application of the choke changes the system resis- tance and alters both gas and sand flow. Choking the flow changes the pressure profile in the system and results in a higher back pressure. Be- cause gas ts compressible, its density increases, resulting in a decrease of flow velocity. The combined effect of a reduction in the gas velocity together with a reduction in sand concentration should sig- nificantly decrease erosive wear. Test work with a variable choke valve has shown that the wear rate is remarkably Iow? If the variable choke be- comes worn such that the throat area increases gradual- ly with time, the desired up- stream or discharge condi- tions can still be maintained with minor adjustments? These choke adjustments can be manual or automatic. It is difficult to determine exactly how much sand the gas conveys and whether the rate of sand flow changes with respect to time. Reasonable assumptions for sand concen- tration values allow approxi- mate calculations. For accu- rate prediction of pressure and velocity profiles, however, it is necessary to obtain some data on the flow parameters. Ideally the mass flow rate or velocity of the gas can be determined, together with the mass flow rate or concentra- tion of the sand. However, ._ these values are vidually im- possible to measure in a well control situation. It is possible, however, to determine quite reliably the pressure gradient in the sys- tern and the absolute pressure at some reference point with two pressure sensors located on the conductor pipe below the diverter (Fig. 1). With the appropriate gas compressibil- ity models for gas/solids sus- pension flows, il is possible to calculate lhe pressure profile throughout the entire cased system. With the pressure data and a computer analysis for a giv- en well configuration and drill- ing assembly, the pressure at any critical point of the system, such as the casing shoe, can be determined instantly. As drilling proceeds, the well con- ditions at the casing shoe change, but the required pres- sure information can be updat- ed. Computer predictions for casing shoe pressure can be fed as input to the choke valve control system. By this means, the choke valve can be auto- matically operated to limit the pressure at lhe casing shoe. In turn, this will limit the gas velocities in the wellhead and surface piping system. Diveder analysis For an example analysis, shallow gas is encountered in a well at a depth of 1,475 ft during hole opening opera- tions. Gas Js swabbed in while pulling out of the hole with the bottom hole assembly at ap- proximately 1,400 ft. The bot- tom hole pressure of the meth- ane gas is 675 psig at 15° C. and 1,475 ft. A convenient starting point for an analysis of shallow gas control is to consider gas flow only. The conductor pipe and diverter arrangement are shown in Fig. 1. Fig. 2 presents the results of the pressure profile analysis for the well. The pressure at the casing shoe reaches about 385 psi when the well flows pure gas. The gas pressure reaches 110 psi (aP) greater than the esti- mated fracture pressure. This clearly presents an ex- lremely dangerous situation. In ordinary well control situa- tic, 110 psi may not be a significant pressure, but in a shallow gas flow it may be enough to cause broaching of the seabed around the con- ductor pipe. The pressure of gas with sand in suspension is not likely to be significantly different from that shown in Fig. 2. The pressure profile shows that the diveder system itself, having a diameter significantly smaller than that of the casing, chokes the gas flow (Fig. 2). T_he only way to relieve this situation is to [~ddc~ i'h~ ~[~- t~nce to fololb-~ irl the su~ the diameter of the diveder P JEff' This has the effect of in- creasing the mass flow rate of the gas through the system. The gas velocity profile changes, resulting in a lower- ing of the pressure at the cas- ing shoe. The diveder ~s a ~ure at the ~sin~~. from 16 in. to 20 in. recovers the prewous example. Any f~r- ther increase in diveder size enables the pressure to drop below the fracture pressure limit. This safe zone allows for lhe operation of a variable choke on the end of the ali- verier line. Manipulation of a variable choke results in reduced wear to lhe system and increases the potential for gaining conlrol of lhe well.~ References 1.

The major concerns associated with this request are: 1) After extensive study of the Cirque #1 blowout and the performance of the diverter equipment on Doyon Rig 14, we have determined that one 16" line with no 90° turns is optimum. 2) To expect valves to operate and seal during high volume flows is not practical. 3) Effective operation of remote valves positioned 100 feet from the rig would be limited. 4) Prevailing winds on the North Slope of Alaska dudng the winter drilling season are generally from SW to NE. With perpendicular placement of the diverter line, there would be a minimum likelihood of gas blowing back toward an ignition source (see attached weather data). 5) A gas dispersion model named "FOCUS" was used to simulate flow from a single 16" line at varying rates and wind speeds aimed towards the rig (see attached results from this simulation). We believe that proper placement of the diverter line with respect to prevailing winds combined with the elimination of turns in the line will make bifurcation of the line unnecessary. David W.

Discussion of Gas Dispersion Analysis This computer simulation of the dispersion of a gas stream away from the end of the diverter line is for the worst case scenario where the wind is blowing directly toward the rig from the end of the diverter line. The diverter line will be pointed in a direction perpendicular to the prevailing winds in the area. The Iow volume amount is 10 million cubic feet of gas per day with the high volume at 60 million cubic feet of gas per day. The gas was assumed to be essentially methane (90% C1, 8% C2, and 2% C3). The Iow wind velocity was assumed at 1 mph. The high velocity of 10 mph was chosen because it is four times the average wind velocity from the SSE. The graph depicts a dotted envelope that is the lower explosion level (LEL) for the gas described above. The outer solid line is a 50% level of the LEL. This adds a safety factor to the diverter design. Recall that ARCO is requiring all contractors to provide at least 100 feet of 16" diverter line away from the w~lll;)0r~. Even in the worst case scenario, the LEL area is well away from the drilling dg. Application for Permit to Drill Colville River #1 4 I~1 . 20. i0.
