Note: This procedure commences with operations to abandon the open perforations 1 O,292!.1 0,352' MD. Due to the unsatisfactory performance of this interval, a decision has been made not to pursue the perforations proposed as Zone #2 and Zone #3 in the original completion procedure. Instead, the following uphole intervals (9440'-9456',8212'-8271', and 8048'-8142' MD) are recommended to be tested. The procedure to test these intervals is as follows: Additional Note: Steps #1-8 have been completed as of February 15, 2002. The reader is directed to Step #9 to review well work proposed to be accomplished point forward. 9.440' Sand Total 9.440' -9,456' 16' NOTE: The SBHP of this Tyonek sand is approximately 2,905 psia (0.453 psi/ft gradient) at 6,413' TVD. 1. Resume operation of Halliburton test equipment. 2. MIRU Schlumberger wireline service with full lubricator and pressure control equipment. Hold Safety and environmental awareness meeting. Pressure test lubricator with 1700 psig wellhead gas pressure. PU and RIH with an empty cement bailer on wireline. Open cement bailer and retrieve a fluid sample from around 10,000' MD. POOH and recover fluid sample. Make arrangements to package the fluid sample and transport it to CT&E Environmental Services (200 W. Potter Drive, Anchorage, 99518 907-562-2343 Attn: Steven Ede) for a full water analysis including chloride count. 3. Plug back Zone #1 (10,292'-10,352' MD) as follows: PU Halliburton 4-1/2" 10K EZ-DRILL cast iron bridge plug w/Baker #1 0 setting tool and GR tool. RIH, correlate depth and set CIBP at 10,250'. Note fluid level while setting plug. POOH with setting tool. Blow down well to separator. 4. PU and RIH with 3.375" HSD guns loaded 6 SPF 60 degree-phased with PJ 3406 HMX 22.7 gram charges to perforate 9440'-9456' MD. API target (5,713 psi) performance is 0.45" entrance hole and 38.6" penetration. Correlate depth with CBT run 12-Nov-2001. RDMO Schlumberger wireline. Fluid level is expected at approximately 7900' MD from last pressure bomb gradient stops in this wellbore. 5. Flow test well to unload liquid. Approximately 23.6 bbls of fluid should be resident in wellbore from fluid level to mid perf at 9948'. If necessary, maximum drawdown is permitted for this interval. Once stabilized flow is attained, it is recommended to attempt to establish stabilized flow with 1000 psi FCP. The unloading rate up 4-1/2" casing is 4.5 MMCFGPD @ 1,000 psig FCP. Consult Anchorage office D. Brimberry for drawdown limitations 907-564-6402. Establish deliverability and obtain gas samples to determine gas analysis flowing well as per direction of onsite production engineer. Contact Anchorage engineering with transient test questions Ben Schoffmann 907-564-6471. Following clean up and constant gas rate, prepare for pressure transient work. NO FLOW CONTINGEf" )(Steps #6 & #7 ) ) If wellbore does not flow, proceed to Step #6. If well flows, proceed to Step #8. 6. RU Slickline company. Hold Safety and environmental awareness meeting. Pressure test lubricator to 4,000 psi. RIH with stand and tandem quartz electronic gauges using roller stem and weight bars as necessary. Make gradient stops to determine fluid level with 2 hour stop on bottom at 9,408' mid perf. COH making same gradient stops. RD slickline equipment. 7. RU BJ Services CT and nitrogen unit. Hook up flowback iron. Fully function and pressure test BOP and rams. RIH w/slick nozzle and jet well to unload liquid. Exact CT procedure will be defined at later time, if necessary. 8. Resume flow test of well as outlined above. · Test is expected to consist of a 24-48 hour stabilized flow period. · A PBU may be elected to determine permeability, skin, pressure, and commercial viability of Tyonek Interval including stimulation potential. · If a PBU is ordered, perform work outlined in the document titled "Ninilchik Field - GO #2 Transient Test Procedure-001".

Dear Mr. Berga: Enclosed is the approved application for permit to drill the above referenced well. . The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. A weekly status report is required from the time the well is spudded until it is suspended or plugged and abandoned. The report should be a generalized synopsis of the week's activities and is exclusively for the Commission's internal use. All dry ditch sample sets submitted to the Commission must be in no greater than 30' sample intervals from below the permafrost or from where samples are first caught and 10' sample intervals through target zones. Annular disposal has not been requested as part of the Permit to Drill application for Marathon Grassim Oskolkoff #2. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

Prior to drilling out of casing strings, test BOPs and casing to the specified pressure listed in the BOP Program section. Plot test and record volume required on the drilling report. Leak-off tests (LOT) are to be conducted as described below: 1. Drill 20' to 25' of new formation below the casing shoe and condition the mud to the same properties in and out. 2. Pull drill string into the casing shoe and close ram preventer, and line up to the choke manifold with a closed choke. 3. Begin slowly pumping fluid down the drill string at 1/2 bpm while recording casing and drillpipe pressures at 1/2 bbl intervals. A running plot of pressure versus volume should be kept by the drilling foreman while the test is in progress. 4. Stop pumping when the pressure curve departs form a straight line sufficiently to indicate leakage into the formation. Record as ppg equivalent mud density in the IADC and morning reports. 5. Monitor and plot pressure drop and time after shut-in for 10 minutes or until the shut-in pressure stabilizes. Bit Program The following guidelines are recommended for use on this well. Actual drilling conditions and dull grading should be used to select the proper bit for the next interval. Insure to have 8-1/2" mill tooth bit for drill out of 20" shoe track.

Existing Roads Existing roads that will be used for access to the MGO #2 well are shown on the attached map. Ninilchik, Alaska, is the nearest town to the site. 2. Access Roads to be Constructed or Reconstructed An existing road and pad on the Oskolkoff property will be utilized. 3. Location of Existing Wells Well MGO #2 will be the second well drilled from the newly constructed pad. The nearest well is the Marathon Grassim Oskolkoff #1, which is approximately 50 feet north 4. Location of Existing and/or Proposed Facilities No facilities are proposed at this time. 5. Location of Water Supply A water well that is located on the pad will be utilized. 6. Construction Materials The existing pad will be utilized. 7. Method of Handling Waste Disposal a) Mud and Cuttings Cuttings will be dewatered on location. The cuttings and excess mud will be hauled to Pad 41-18 in the Kenai Gas Field for disposal into Well KU 11-17, a Class II disposal well (AOGCC Disposal Injection Order No.9, Permit #81-176). N:\DRLG\W ELLS\MG02\SU RFUSE.doc ) Surface Use Plan Marathon Grassim Oskolkoff #2 Well Page 2 b) Garbage All household and approved industrial garbage will be hauled to the Kenai Peninsula Borough Soldotna Landfill. c) Completion Fluids Clear fluids will be hauled to Pad 34-31 of the Kenai Gas Field and injected in Well WD #1, an approved disposal well (AOGCC Permit #7-194). d) Chemicals Unused chemicals will be returned to the vendor who provided them. Efforts will be made to minimize the use of all chemicals. e) Sewage Sewage will be hauled to the Kenai sanitation facility. 8. Ancillary Facilities A minimal camp will be established on the pad to house various supervisory and service company personnel. Approximately four trailer house type structures will be required for this purpose. Bottled water will be used for human consumption. Potable water will be obtained from the water well on the pad. Town & Country will collect and transport sanitary wastes to their ADC approved disposal facility. No additional structures will be necessary. 9. Plans for Reclamation of the Surface Well MGO #2 will be drilled from an existing pad. Reclamation of the pad, if required by the landowner, will occur after abandonment of MGO #1 and MGO #2. 10.

"'·"11 } ') BHL and Target Proximity Determination Marathon GO #1 and #2 Marathon has drilled the Grassim Oskolkoff #1 (GO #1, PTO 200-082) from a surface location in the Ninilchik vicinity on the Kenai Peninsula. Marathon is proposing to drill a second well (GO #2, PTD 201-096) approximately 50' away at surface. The plot provided in the application for GO #2 is rather large scale and the purpose of this document is to provide a record of the determination of the wellbore proximities both at the top of the proposed producing interval (Target 1) and at TD. Since these wells are intended as gas wells, statewide rules specify a minimum distance between the wells of 3000'. I have examined the information available for the GO#1 (planned and actual) and the GO#2. Based on the calculations documented below, the planned GO#2 wellpath is 3171' SSE of the actual GO#1 at the top of the pay (-4000' TVO) and 4303' SSW of the actual GO#1 at TO (-8500' TVD) GO#1---Actual Target (4000') GO#2---Proposed Path (4000') GO #1---Actual BHL from 407 GO #2-BHL proposed 916 F8L, 1353 FEL, 815, T1N, R13W, 8M 3293 F8L, 76 FEL, 822, T1N, R13W, 8M 1935 F8L, 2767 FEL, 815, T1N, R13W, 8M 3293' F8L, 741' FWL, 822, T1N, R13W, 8M Following are the respective calculations for target and BHL locations. GO #1 Target is [916 + (5280 - 3293)] = 2903 feet north of GO #2 GO #1 Target is [ 1353- 76) ] = 1277 feet west of GO #2 The resulting distance between the targets is (2903^2 + 1277^2)**1/2 = 3171' GO #1 is [1935 + (5280 - 3293)] = 3922 feet north of GO #2 GO #1 is [ (5280 - 2767) - 741) ] = 1772 feet east of GO #2 The resulting distance between the BHLs is (3922^2 + 1772^2)**1/2 = 4303' Based on the above, the proposed target and BHL locations for GO #2 meets statewide well separation requirements.

Upon drilling out the drive pipe, erratic torque was experienced along with the mud motor stalling with little to no weight on the bit. All symptoms indicated that the bottom of the drive pipe had been pinched. A flat bottom mill run (BHA#2) was made to open the pipe up. It was followed up with a conventional slick rotary assembly including a junk sub (BHA#3) to drill 50' of new hole and assure that there were no more obstructions nor any junk left in the hole. · The kick-off was commenced with a traditional steerable assembly (BHA#4) containing a 12-118" string stabilizer located just above the mud motor. Directional control was attainable until 791' at which point the assembly suddenly began hanging up in the sticky plastic shale formations. Sliding became extremely difficult if not impossible. A BHA trip was required to remove the string stabilizer. The assembly was therefore pulled out of the hole at 865' to remove the above-mentioned stabilizer. · Drilling resumed with the modified BHA#5 down to 1562', and again sliding became gradually worse with each set. It was obviously not beneficial to just continue struggling along at such a rate. A group discussion was conducted concerning all involved to get opinions and weigh all options as to what action(s) could be taken to possibly rectify the problem. A decision was agreed upon to pull out of the hole and lay down all the slick 8" monel drill collars and run D-raw algorithms to correct for any magnetic interference. This alternative was not originally implemented due to a potential +/- 4° variance on the azimuth values which was highly influenced by a combination of the due west hole direction and the somewhat high hole angle. It would also be recommended to try using a 12" or 11- 15/16" UBHS sleeve on the mud motor to further reduce any possible hanging problems while drilling in slide mode. · The above mentioned modified BHA#6 would successfully drill down to the proposed 9-5/8" casing point at 2500' without any problems. · The casing was run and cemented in place at 2500', also without any incidents. The entire run for this hole section consisted of drilling a total of 2357' in 79.6 actual hours on bottom resulting an overall average rate of penetration of 29.6 ft/hr. Also, the 12-114" section was drilled entirely with roller cone bits to assure good steerability for directional control. Mb 1 Db 8-1/2" Hole Section · A 6-3/4" Inteq AutoTrak rotary steerable system (BHA#7) would be utilized to assure the highest possibility of drilling a smooth gauge hole and essentially without any variable doglegs in the drop section which allows for the best chances of getting the 7" casing to bottom. It was run in conjunction with a 8-112" Hughes Christensen DP0622 PDC bit, which has been designed specifically for drilling in the Cook Inlet area. A couple of problems while drilling this section were anticipated by all involved with a high probability that may substantially reduce the overall drilling performance: 1.) The rig's limitation of surface RPM's would not be sufficient enough to utilize the PDC bit's drilling capability. 2.) The maximum allowable pressure on the pump liners would be exceeded as a result of the tluid volume output requirement for optimum hole cleaning properties. In lieu of these limitations, the drilling operation would take part in an attempt to prove that the objecti ve well's 8-1/2" hole could be success full y drilled outside of the rig's boundaries. ') ) · Drilling the 8-112" hole section commenced as the cement and PDC drillable float equipment were drilled out and a leak-off test was performed. While drilling, short trips were made every 1000 ft. back to the 9-5/8" casing shoe. Each stand was back-reamed up and washed down once prior to making each connection. By the time the hole depth had reached 4507 ft., the flow rate had been gradually reduced from 520 gpm to 460 gpm in an effort to prevent exceeding the pump liners' maximum operating pressure of 2150 psi. Upon a short trip, while inside the shoe were the liners changed out from 5-112" to 5" in an effort to avoid further reducing the flow rate. The top drive was only capable of turning at a rate of 70 surface RPM's in low gear. Several unsuccesful attempts were made to drill in high gear which was capable of rotating as fast as 135 RPM's. The high torque could not be overcome and the system would continuously stall out as a result. This was no longer an option. The assembly continued drilling with down to 6500' at which point would a trip be made to pick up the triple combo L WD tools. It was recommended to drill further with the PDC bit to assure that T.D could be undoubtedly reached with the next bit run regardless of what type of bit used. A total of 4007 ft of hole was drilled in 126.1 actual hours on bottom drilling time for a resultant penetration rate of 31.8 ft./hr. The bit was pulled above the rotary, inspected, and was virtually untouched. There were no signs of any wear on the 19mm cutters and it was still in gauge. A 13mm impact cutter located on the nose was missing which had no impact on it's actual drilling performance. Upon a surface test, it was discovered that one of the ribs on the steering unit of the AutoTrak tool had no hydraulic pressure applying on it. Therefore the tool was laid out and replaced. Unfortunately, the new steering unit that was picked up would not communicate with the RNT tool. Another tool was then picked up and it tested rme along with the triple combo logging tools. · The PDC bit was laid out and an insert bit was picked up (BHA#8) in attempt to increase the penetration rate. Questions of concern were discussed about running the insert bit with so much hole left to drill. It seemed unlikely that the insert bit could out-drill the PDC bit and make it to T.D without making another bit trip. Therefore re-running the DP0622 was the recommended bit of choice. A MADD pass was made upon running in the hole to log a section from 5000 ft. to bottom at 6507 ft. Drilling resumed with the insert bit on the AutoTrak system. The new bit tugged along drilling at a significantly slower rate. Nothing more could be done concerning the rig's limitations to improve matters, it was something that just had to be dealt with. A short trip was made 7185 ft. and again, the flow rate required a gradual reduction from 430 gpm to 383 gpm to maintain below the pump liners' maximum operating pressure of 2597 psi. The hole was drilled down to 7788 ft. at which point a bit trip was made due to the high hours on it. The bit drilled a total of 1281 ft. in 71.8 actual hours on bottom drilling time for a resultant penetration rate of 17.8 ft./hr. The bit looked fine upon surface inspection. · A new insert bit of the same type was picked up (BHA#9) and run in the hole. Upon tagging bottom, the bit had problems drilling. High torque was experienced and the assembly literally would not drill. The ribs on the Autotrak tool were turned off and no improvement was noticed. This created a very slight variation from the proposed well plan as the required dogleg was not achieved and slightly larger doglegs were now required as a result. The hole section appeared to have been correlating with the MGO#l well which convinced all that the problem was simply the formation itself. The Lube-Tex concentration in the mud system was increased to 3-112% and a significant improvement was noticed. The torque dropped off and smoothed out, and the penetration rate also showed signs of improvement. At 8232 ft. a short trip was made back to 6600 ft. Backreaming was required from bottom to 7700 ft. and the rest pulled rme. The remainder of the 8-112" hole section was reached at 8530 ft. (7" casing point) without any further incidents The hole is lined up at this point to drill straight to the GO #2 lower target at 8500 ft. (TVD). A wiper trip was made to the shoe and ran back to bottom with out any problems whatsoever. All indications show the hole to be in excellent condition. The bit was pulled out of the hole and also looked fine upon surface inspection. A total of 742 ft. were drilled in 52.7 actual drilling hours on bottom for a resultant penetration rate of 14.1 ft./hr. · The AutoTrak system performed absolutely flawless while drilling. It is believed that the HC DP0622 PDC bit could have not only drilled the 8-112" hole section at nearly twice the penetration rate, but also would have eliminated a bit trip out of the hole. Should this be the case, it would have significantly reduced the cost of this hole section and also increased the overall drilling performance by a significant amount as well. Mb 1 Rm 1 1m 1 Em 1 Kt ) ) 7" Hole Section · A 7" hole would be drilled using a Hughes Christensen DOSRWD which used the same concept as a hi-center bit. This would assure the best chance of getting the 4 '12" liner all the way down and also a good cement bond. The DOSRWD technology was chosen over a conventional bi-center bit for its proven ability of directional control. The conventional bi-center bit type has a notorious reputation for being erratic and unpredictable. · The cement and float equipment were drilled out along with 20 feet of new hole, displaced with new Ao-Pro mud and a leak-off test performed. Drilling resumed at 8550' and occasional slides were required as the bha had a very slight left-hand walk tendency. Sliding was difficult at fIrst, but not impossible. No fIll was left in the hole. · Short trips prove to be no problem because the tools are smaller than the drilled hole size, relieving the worry of hole swabbing. · The DOSRWD and 4 3,4" STR444 far exceeded our expectations. It drilled 3496', well TD. The slides to control along the planned trajectory were only 3.19% of the total footage drilled. Although the sliding penetration rate was slow, it was very controllable. The rotating ROP was far greater than we expected. I can't imagine a stable motor assembly doing a better job. I believe that there will be further need of this technology on future wells in this part of Alaska. Tw = ') BOTTOM HOLE ASSEMB~} INTECI.

Daily Drilling Report ) ) 1. Introduction Introduction Baker Hughes INTEQ was contracted to provide AutoTrak rotary closed loop drilling services for the 8 %" sections of the Grassim Oskolkoff MGO #2 hole. The primary reason for using this system was to evaluate and gain operational experience with AutoTrak prior to its possible application to subsequent extended reach drilling projects. By virtue of constant rotation and steering, the AutoTrak tool has been shown to improve drilling efficiency and hole quality in such applications. The AutoTrak service was utilised in the 8 %" Section. Grassim Oskolkoff MGO #2 was an US"-Type well. The AutoTrak service was used to drill the tangent section at an angle of 270 degrees azimuth and 65 degrees inclination before dropping to 14 degrees inclination before penetrating the target. , i ') ) 2. RiQ-uP A full MWD surface system was rigged up from the previous hole section drilled using NaviTrak (Directional-Only) tools. The bypass system required for surface to downhole communication was installed behind the standpipe on the drillfloor, such that rig operations would not be affected. An LCD display was provided at the driller's console to display drilling, formation and ECD data real-time. 3. DrillinQ Directional DrillinQ Summary Grassim Oskolkoff MGO #2 The first AutoTrak run, using Hughes Christensen's 8-1/2" DP0622 pdc bit, went very well. AutoTrak responded exceptionally well when downlink commands were sent. D.L.S. needed during this run was achieved as expected. However, drilling with the top drive in high gear was not possible. High Gear could not be used during the subsequent AutoTrak runs as well. Because of these limits, 70-75 rpm's was the maximum rpm achievable. Frequent short trips were planned to assist in hole cleaning. This assembly was pulled due to excessive on bottom torque. Because of the excessive torque seen, it was decided to pickup a tri-cone bit (Smith's 15GFDG). In an attempt to reduce the excessive torque while drilling, this bit was chosen. However, it made no difference at all. By having a tri-cone bit in the hole, it subsequently led to an additional bit run. The same AutoTrak tool was run and achieved the same excellent results as did the two previous runs. Another Smith (15GFDGPD) was picked up for the third and final Autotrak run. An important point to note is that when bits other than PDC's designed exclusively for AutoTrak are used, the actual cost savings associated with Autotark's utilization are usually negated. - ') ) Well: Grassim Oskolkoff MGO #2 AutoTrak Run 1 (2500ft - 6506ft) AutoTrak Generation 2.5 tool SIN ASS1 001 0244 was picked up. The tool had been pre-programmed on deck and all that was required on the drillfloor was a quick tool communication check and sensor verification. It was made up to a 8 Y2 HC DP0622 PDC bit, dressed with nozzles to a TFA of 0.9073 sq.in. A shallow hole test was performed at approximately 1000 feet. All data was as expected and tripping in hole continued. Drilling commenced at 2500 feet having downlinked to take the AutoTrak tool out of ribs-off mode and into hold mode. Surveys were taken at each connection. These were then used as the definitive surveys for all calculations. Maintained wellpath over the section by downlinking to the AutoTrak tool. Generally this involved small "nudges" to the walk rates and target inclination. After drilling to 6506 feet, the assembly was tripped out of hole to check the bit due to concern with slow ROP. Total hours for this 4006 ft run were 1 05 hours drilling and 158.4 hours circulating. AutoTrak Run 2 (6506ft -7789ft) AutoTrak Generation 2.5 tool SIN ASS10010244 was laid down as a precaution after noticing suspicious behavior in one of the hydraulic ribs. AutoTrak Generation 2.5 tool SIN ASS1 0017259 was picked up along with Triple Combo tools. The tool was re-programmed on deck to run with the Triple Combo suite. All that was required on the drillfloor was a quick tool communication check and sensor verification. It was made up to a 8 Y2 Smith 15GFDG tricone bit, dressed with nozzles to a TFA of 1.325 sq.in. A shallow hole test was performed at approximately 100Oft. All data was as expected and tripping in hole continued. The previously drilled hole section was logged at 180 ft/hr from 5500 feet to 6506 feet with the Triple Combo suite. Drilling commenced at 6506 feet having downlinked to take the AutoTrak tool out of ribs-off mode and into hold mode. Surveys were taken at each connection. These were then used as the definitive surveys for all calculations. Maintained wellpath over the section by downlinking to the AutoTrak tool. Generally this involved small "nudges" to the walk rates and target inclination. After drilling to 7789 feet, the assembly was tripped out of hole to check the bit due to concern with slow ROP. Total hours for this 1283 ft run were 71.4 hours drilling and 102.7 hours circulating. AutoTrak Run 3 (7789ft - 8530ft) AutoTrak Generation 2.5 tool SIN ASS10017259 and Triple Combo tools were rerun after picking up a new. 8 Y2 Smith 15GFDG tricone bit, dressed with nozzles to a TFA of 2.350 sq.in. All that was required on the drillfloor was a quick tool communication check and sensor verification. A shallow hole test was performed at approximately 100Oft. All data was as expected and tripping in hole continued. Drilling commenced at 7789 feet having downlinked to take the AutoTrak tool out of ribs-off mode and into hold mode. ~ ') ) Surveys were taken at each connection. These were then used as the definitive surveys for all calculations. Maintained wellpath over the section by downlinking to the AutoTrak tool. Generally this involved small "nudges" to the walk rates and target inclination. After drilling to 8530 feet, the assembly was tripped out of hole to run wireline logs and casing. Total hours for this 741 ft run were 52.7 hours drilling and 65.4 hours circulating.

LOQ Performance Report This report covers log performance of the RNT sub 20016 run with AutoTrak tools ASS 10017259 and 10017259. The logs provided on the rig were Measured While Drilling (MWD) and Recorded While Drilling (RWD) logs for the original 8 1/2" hole section on a depth scale of 1 :240 MD, 1 :240 TVD, 1 :600 MD and 1 :600 TVD. Well: MGO #2 8 1/2" Hole Section drilled with AutoTrak ( 2500 feet - 8330 feet) Introd uction Integrated in the AutoTrak tool is an RNT (Reservoir Navigation Tool) dual transmitter compensated resistivity device. A Triple Combo suite was run above the AutoTrak tool during the last two runs. Tool Performance 8 112" Hole Section All resistivity and gamma ray measurements in the 8 Y2 inch hole section were taken with the same logging sub RNT 20016 This section was logged in three runs. During the last two runs a Triple Combo suit was added to the logging package. Reaming for Triple Combo data began at 5500 feet MD and continuous log was acquired to TO. LOQQinQ Conditions Real time data was acquired at 0.5 bits/see with 100 % decodeability. Data density was moderate. Hole conditions were excellent over the complete section and did not detract from the log quality. An occasional gap was noted realtime data. These coincided with downlinks (Transmitting directional commands to the tool from surface) while drilling and transmitting surveys while drilling. This did not however affect the quality of the memory data, which was excellent. 5. Downlink Summary During the course of drilling operations one bypass actuator basket was used BSS 6219. A total of 74 downlinks were attempted with 70 being successful. The initial equivalent nozzle size was increased from 19.0 to 12.6 when the initial two downlinks failed. Following this adjustment only one further downlink was unsuccessf ul.

Comments and Recommendations Discussion & Conclusion This was a very successful deployment of AutoTrak. All objectives were either met or exceeded. Hole Cleaning: The primary problems encountered stemmed from poor hole cleaning. Poor hole cleaning was likely aggrevated by low RPMs used while drilling. The capability to turn at desired RPM (-150) was not possible due to rig limitations. Observations were: . When drilling through the coal beds on this well, the cuttings over the shakers were seen to be very large and had not been cut by the bit. Caliper readings through these beds show the hole to be between one and two inches over gauge. . While drilling ahead at 70 RPM, high values of "Stick-Slip" were transmitted by the AutoTrak tool. Values of "Stick-Slip" were much lower in the upper part of the 8 112 inch hole section were it was possible to rotate at 130 RPM. Due to the inability of the drilling rig to turn at a higher RPM in th elower 8 112 inch hole section, the slick slip was not able to be eliminated. High values of "Stick-Slip" can cause damage to MWD tools and should be avoided whenever possible. Hole Gauge: Caliper readings show the hole to be between 8 3,4" and 9". The only section to show considerable wash were coal beds. The caliper show the hole to between one and two inches over gauge in these beds. Any area subjected to extended circulation also exhibited varying degrees of wash. Log Quality: Log quality was very high. Deviation Control: The well path (a 65 deg tangent with a drop to 14 degrees) did not offer a real challenge to the known steering capabilities of the AutoTrak system. However, without doubt the ability to set and hold inclination as desired helped to minimise wellbore tortuosity. This in itself is a major contributing factor in the ability to drill extended reach wells.

Could use more pressurelpump capacity for bit hydraulics, more flow for hole cleaning, and more RPM for the POC. Changing pump liners will drop flow rate close to ATK dropout and reduce hole cleaning. However, will need the extra pressure capacity to compensate for increasing pressure drop across drill string. Please discuss the increased pressure drop from Nuclear subs, and increased drag/torque from Density stabilizer. Is it possible to run nukes as a MAD pass? Resistivity will be real-time no matter what. The use of a mud motor will increase RPM at the expense of pressure drop. Suggest the use of Low flow turbines on future wells. With 10% safety factor we could pump 495gpm through a low flow. All considered, we are still drilling pretty good, and are slightly under the time curve.

Pick up weight without rotation is 95k to as much as 125k, with 3 - 4 feet of fill. Pick up weight with rotation is 70k and smooth. The risk of damaging a rib/hydraulic seal would seem to be less while rotating than without rotation, and hole cleaning is also improved. Stick slip is continuously reading 5 to 6, but lateral and axial vibration remain 0 to 2. This is not atypical and stick-slip by itself does not seem to be too harmful to the tools. In low gear at 60 tò 70 RPM there is no room to adjust RPM to minimize stick slip anyway.

KEMALAWATI ( ( n EPOC=H 4 (!!!) Marathon Oil Company - Grassim Oskolkoff #2 ( DRILLING SUMMARY PROSPECTUS The objective of Marathon's GRASSIM OSKOLKOFF #2 was to drill a hole to evaluate and establish a productive gas well in the Tyonek Formation. The surface location was Grassim Oskolkoff property at mile marker 124 on the Sterling Highway. The procedure was to spud a well and step out directionally to the west. BRIEF REVIEW OF ACTIVITY ( The drilling rig was Marathon's Glacier Drilling Rig #1. A 13 3/8" conductor pipe was set to 143'. 12 %" hole was drilled building 3 deg/100' and holding an azimuth of 270 deg. The well was spudded on 15 September 2001. 9 5/8" casing was set at 2498'. 8 %" hole was drilled using Baker Hughes Inteq's AutoTrak Rotary Steering Assembly. The 65 deg hole angle and 270 deg azimuth was maintained to 6923'. Then the hole angle was dropped at 3 deg per 100' as per well plan until 13 % deg was reached at 8530'. The 270 deg azimuth was held constant. Wireline logs were run on drill pipe by Schlumberger and 7" casing was set at 8523'. A 7" hole was drilled using a 4 %" pilot bit with a 7" DOSRWD. Azimuth and inclination were maintained at approximately 270.0 deg and 12.0 deg respectively. A final depth of 12026' MD and 8483' TVD was reached on 26 October 2001. Schlumberger e-Iogs were run and 4 %" casing was set. There were no significant problems encountered during the drilling, logging and completion phases of this well. LOGGING PROCEDURES Epoch Well Services provided RIGWA TCH 2000™ Drilling Monitoring services and DML TM Mudlogging Service. Hydrogen flame ionization total gas and chromatograph detectors were employed to detect and analyze formation gases. Constant mud gas was generated by an air motor driven gas trap located at the shale shaker header box and extracted continuously from the trap to the unit by sample pumps. The gas trap was cleaned and positioned to obtain optimum sampling, and the gas system was tested and calibrated regularly. Cuttings samples were collected at regular 10' - 20' intervals as directed by Marathon's sampling program and drill rate allowed. t ~ EPOCH 5 (!!)Marathon Oil Company - Grassim Oskolkoff #2 ( CAlLY CHRONOLOGY 9/1512001: Nipple up diverter stack.
