Date of Examination: 8 August 2006 Field Investigator: Robert Lewellen, Ph.D. Accompanying Pioneer Representative: Don Graka. • Utilizing helicopter support, Lewellen and Graka examined the tundra conditions at the Cronus project location. Also, on site, were Gary Schultz and Larry Byrne of DNR, State of Alaska. From the air, approaching with the helicopter, we were unable to spot any disturbance. The pilots finally located the drill pad well site and landed. The four of us walked over the tundra and completely missed the disturbed areas between the drill pad and the water source lake. Lewellen finally found the old GPS point and got back to where the disturbance was examined on July 26, 2006. The field examination revealed a significant regrowth of new sprouts; compare the photographs from 26 July versus 8 August. I cannot see any long term problems with this drill site and associated roads. Gary Schultz told me that he did not think there was any long term disturbance. We all agreed that the problem was the travel over a tundra terrain which did not have an adequate processed snow cover. Larry Byrne mentioned that there were differences between the terrain at Hailstorm and the terrain at Cronus. He was pointing out the relative smooth wet sedge meadows of Hailstorm and the tussock dominated areas of Cronus. He was implying that the road construction techniques had to be different. The difference in terrain is not of any significance because any type of tundra terrain has to be protected. It is the degree of work and snow/ice material required to provide the protection. The road building techniques are the same from Alaska to Minnesota and Canada to Finland. When I left Prudhoe, I saw Dave Cruz in the airport. He brought up the Cronus site voluntarily. He mentioned something about the Volvo water trucks were out of the road alignment, and traveling on tundra which had insufficient protection. The information in my report of 26 July is still valid; there was a lack of training for the individual equipment operators and a lack of supervision. Any operator should know when to stop his equipment and notify the supervisor there is a problem with inadequate tundra protection. Lewedden Arctic Research, Inc.

However, one interesting aspect appears in photo image # 1397. When I turned over this piece of tussock (which had been separated from a tussock) the vegetation had sprouted on the side lying against the tundra surface. The plants were growing on both the fragment and on the tundra surface, but were light green, and yellow from the lack of sun. But, the plants were growing. The dark aspect of this fragment is because the tussock was predominately made of peaty organic material and very little mineral soil.

Please note that any disposal into the surface/production casing annulus of a well approved for annular disposal must comply with the requirements and limitations of 20 AAC 25.080. As provided in AS 31.05.080, within 20 days after written notice of this decision, or such further time as the Commission grants for good cause shown, a person affected by it may file with the Commission an application for rehearing. A request for rehearing is considered timely if it is received by 4:30 PM on the 23rd day following the date of this letter, or the next working day if the 23rd day falls on a holiday or weekend. A person may not appeal a Commission decision to Superior Court unless rehearing h.as been requested.

("Pioneer") requests approval for annular disposal in the subject well. This note analyzes information submitted by the ap- plicant and recommends approval of this request for annular disposal. Hailstorm #1 9-5/8" surface casing was set at 2940' and cemented with 406 bbls lead cement followed by 45 bbls tail cement, totaling about 175% excess cement relative to gauge wellbore. 10 bbls of lead cement circulated to surface during initial placement, during which full returns circulated. Successful placement of such volumes of cement indicates that Hailstorm #1's surface casing is ade- quately cemented. The formation below the 9-5/8" casing shoe supported an 11.8 ppg EMW leak off testa Applied. pressure dropped 58 psi (from 523 psi) during pump in and de- clined to 465 psi in 10 minutes. Hailstorm #1 was then drilled to 9496', and 7" casing set and cemented at 9460'. There are no wells within Hailstorm #1's AOR. Based upon information submitted, AOGCC recommends approval of Pioneer's request for annular disposal in Well Hailstorm #1 (PTD 205-185).

After several attempts at jarring the fish free over the weekend, we tripped in the hole early yesterday morning (28Jan06) and spotted a 259 sack 17.0 ppg Premium cement plug from the top of the fish at 5,009' to 4,398'. 4,398' was confirmed this morning at 0530 hrs when we tagged the top of cement with our BHA. We axe currently in the hole with a directional BHA, taking surveys via a gyroscope. We will time drill the first. 5 feet to get off of the cement plug and into new formation and then we are going to directionally drill due west (270 deg azimuth) at a 4 degree/100 feet dog leg severity for a couple of stands and. then turn it back down .and drop it back to vertical. The ultimate goal is to .have 50 feet of departure from the fish and the original hole when we get the drill string back to vertical. The expected deviation of the hole will not exceed 15 degrees. Please let me know if you need any additional information, Winton.

This permit to drill does not exempt you from obtaining additional permits or approvals required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. 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. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. Please provide at least twenty-four (24) hours notice for a representative of the Commission to witness any required test. Contact the Commission's petroleum field inspector at (907) 659-3607 (pager). Sincerely, DATED this 't day of month, 2005 cc: Department of Fish 8a Game, Habitat Section w/o encl.

(PNRA) hereby applies for a Permit to Drill an onshore exploratory test well from the referenced location. The well is designed to penetrate, evaluate and test the production potential of the Ivishak sand.' As indicated in the attachments, the drilling program will entail drilling a 12%4" surface hole to approximately 2,995 ft. MD/TVD, where surface casing will be set. An 8'/s" vertical wellbore will be drilled to the top of the Sag River ~-- formation at approximately 9,440 ft. MD/TV re intermediate casing wiN be set. The well will be finished with a 6%8" vertical hole to 1 ,3 ft. MD/TVD through the Ivishak target interval. E-line logs will be run at the end of the 12%4 ; '/", and 6%" hole sections. If the Ivishak target is determined to be productive, a 4'h" liner will be run for possible future testing. It is anticipated that there will time to conduct a well test on the Hailstorm #1 this season, if deemed necessary. ~ The proposed casing program will utilize 95/" surface casing, 7" intermediate casing and a 4'/" production liner (if completed). Please find attached information as required by 20 AAC 25.005 (a) and (c) for your review. Pertinent information attached to this application includes the following: 1) Fee of $100 payable to the State of Alaska per 20 AAC 25.005 (c) (1). 2) Form 10-401 Application for Permit to Drill per 20 AAC 25.005 (a). 3) A plat showing the surface location proposed for the well per 20 AAC 25.005 (c) (2). 4) A copy of the proposed drilling program per 20 AAC 25.005 (c) (13). 700 G STREET.

A wellbore schematic is also attached visually depicting the proposed well. 9) The drilling fluid program as required by 20 AAC 25.033 is attached in this Application for Permit to Drill package. 10) Complete logging and mud logging operations are planned and descriptions are attached. 11) PNRA does not anticipate the presence of H2S in the formations to be / encountered in this well. However, H2S monitoring equipment will be functioning on the rig as standard operating procedure for all wells drilled by that rig. A copy of Doyon's H2S Contingency Plan has been attached to this application and is intended to be filed with the AOGCC as PNRA's contingency plan for H2S for all wells drilled on the North Slope while using the Doyon Akita Artic Fox Rig #1. PNRA proposes the following additions to this drilling permit: 1) PNRA requests authorization for the disposal of drilling waste via the annulus and will do so by filing with the AOGCC a 10-403 supplement with additional information as required under 20 AAC 25.080 when the intermediate interva{ has been drilled and cased. 2) Regarding diverter use, PNRA requests an exception to 20 AAC 25.035 (c) (1) (A) & (B). PNRA plans to use a 12" diverter vent line while drilling the 12'/4' surface ~ hole. 3) PNRA would like to request a waiver for porosity logs in the surface hole in accordance with 20 AAC 25.071 (c). The geologic staff has determined that /. resistivity and gamma ray logs will be run and will provide data in the 12'/4' surface hole, but no data will be obtained from the porosity logs due to lithology and hole conditions. 4) PNRA requests a variance to 20 AAC 25.035 (e) (1) (B) (i). PNRA requests that it / not be required to change out the pipe rams to fit the liner while running the 4'/2' production liner for the following reasons: a. the time required to run the liner is similar in nature to bottom hole assemblies (BHA), which do not necessitate a pipe ram change; Alaska Oil & Gas Conservation Commission November 15, 2005 Page 3 of 3 b. a crossover from the liner running threads to the drillpipe threads is always available on the rig floor to allow for a change over for the rams to close against; and c. the annular preventer could be closed on the liner at any time with the float equipment preventing any kick from flowing inside the liner. The following are PNRA's designated contacts for reporting responsibilities to the Commission: 1) Completion Report Vance Hazzard, Drilling Superintendent (20 AAC 25.070) 907/343-2116 hazzardv@pioneernrc. com 2) Geologic Data and Logs Tavia Bicklein, Senior Operations Geologist (20 AAC 25.071) 907/343-2133 bickleit@pioneernrc.com The anticipated spud date for this well is December 6, 2005.

It is requested to remain on file with the AOGCC for future well permit applications. DISPOSAL: Annular Injection: An annular injection permit will be filed for this well once the cementing of the intermediate casing is completed. Cuttings Handling: Cuttings generated from drilling operations will be processed and disposed of at the Grind and Inject Facility at Prudhoe Bay Unit Drillsite 4. Fluid Handling: All Class I fluids will be processed and disposed of at the Prudhoe Bay Unit Pad 3 waste injection facility.. All Class 11 fluids will be processed and disposed of at the Grind and Inject Facility at Prudhoe Bay Unit Drillsite 4. SURFACE HOLE SECTION: • Mudloggers will be rigged up throughout the entire section. ~ • No significant drilling problems have been identified in the surface hole interval based on offset data. Good hole cleaning and management of required mud properties are key to a successful interval. • Minor tight hole conditions have been noted in the shale intervals immediately below the permafrost during short trips. • Differential sticking could be problematic in this hole section adjacent to the permeable SV sands. Avoid leaving drill string stationary for extended periods, tighten fluid loss properties of mud, and string in Barofibre as required prior to penetrating sand intervals. • Lost circulation has not been noted while drilling any of the offset wells and no losses were noted while running and cementing surface casing. Be sure to condition and thin mud appropriately prior to pulling out of the hole to run casing, and once on bottom with casing, bring circulation up slowly and reduce mud viscosities before pumping cement. • Hole stabilization in the shallow unconsolidated intervals can be problematic if mud properties are relaxed. Hi viscosities as used elsewhere on the North Slope should be sufficient to control any potential running gravels. • Gas hydrates may be present near the base of the permafrost. Mudloggers will be used continuously on Hailstorm #1 to help identify and trend any increase in background gas readings. If gas hydrates are encountered, mud weight may be increased to 10.0 ppg and treated with 2 ppb DRILTREAT ( cithi Additional measures include reducing flow rates to 450 to 500 gpm, control drilling through th zone at 40 to 60 feet per hour and keeping the mud temperature cool Pioneer Natural Resources Alaska, Inc. Last Revised: November 15, 2005 Hailstorm #1 Permit Application INTERMEDIATE SECTION: • • BOPE will be nippled up and tested prior to drilling the intermediate section. • Mudloggers will be rigged up throughout the entire section. • Mudloggers will be used continuously on this well to help identify and trend any increase in background gas readings. Surface casing will be set prior to any intervals with previously noted gas shows to facilitate nippling up the BOP's. A minimum of 9.0 ppg is recommended. • To prevent the initiation of lost circulation, the rheology of the system has been reduced while still -- providing ample hole cleaning. Maintaining a low ECD while. circulating and eliminating high pressure spikes while tripping should reduce the risk of lost returns. • Two forms of stuck pipe are possible. One is from hole pack-off as related to poor hole cleaning, i.e. a cuttings bed.. Stuck pipe can occur if a cuttings bed forms, or if the wellbore exhibits severe instability. The best cure is to pro-actively prevent the occurrence of either scenario in the first place, and if they do occur, correct drilling practices must be employed. If pulling up into a tight spot, do not jar up further, but attempt to get below the problem. Backreaming a large cuttings bed is an invitation to packing off and resulting stuck pipe, and backreaming must be done with care and-only when necessary. If stuck pipe occurs across a sand and there are indications of differential sticking, there are drilling fluid solutions. If possible, reducing the fluid density by a minimum of 0:5 ppg may provide some relief. • The HRZ and Kingak can be problematic. Ensure the mud weight is .10.0 ppg prior to entering the HRZ and reduce the HTHP to less than 10cc. Due to .the short length between the HRZ and Kingak, the weight needed for the Kingak will be applied for the HRZ. Should any signs of shale splintering be seen, immediately raise the mud weight a minimum of 0.4 ppg. Keep instantaneous surge/swab limited. Awareness by the rig crews as to the fragility of these shales to mechanical disturbance is of great importance. PRODUCTION SECTION: • Mudloggers will be rigged up throughout the entire section. Gas in the Sag River or Ivishak will be ~'' circulated out as required. • The drilling liner shoe will be drilled out with the inhibited mud system used in the intermediate hole. The hole will then be displaced with a 9.3 ppg drill-in fluid.. • Differential sticking is not anticipated but the drill string should not be left stationary for any length of time. / • Losses are not expected but calcium carbonate (CaCO3) will be maintained in the system. • The Ivishak formation has a conglomerate section present at times in the area. Whole Vosses can occur if significant overbalance is present and lost circulation material has not been adequately added to the system. • .The well is not planned to penetrate the Lisburne limestone, but will penetrate the Kavik Shale. The onsite geologist will be in charge of picking the base of the Ivishak and it is planned to drill enough rathole to bury open hole logs and provide room to drop off perforation guns should a completion be made. However, if the Lisburne is penetrated, the LCM Decision Tree will be in place on the rig.

Drilling Hazards and Risk Analysis of the Proposed Hailstorm #1 Well (To be located 3,543' FSL, 5,009' FEL, Section 2, T9N, R13E, UM) The purpose of this letter is to document PNRA's drilling hazard evaluation for the proposed Hailstorm No. 1 Well, estimated to spud December of 2005. In our shallow hazard and pore pressure risk analysis of this well we examined interpretation of the 3D seismic data, seismic velocity information and available relevant offset well data. Our evaluation of this data shows no indications of apparent drilling hazards or risks. The analyses of this data are not definitive, however. Therefore, PNRA will work on the assumption that the possibility of encountering drilling hazards exists and work to establish drilling processes to mitigate those risks. Log and drilling data from nearby wells used in our analysis includes the Hemi Springs Unit #3 (closest to prospect, 2.5 miles southeast), the Hemi Springs State #1, and the Sequoia #1. The Storms 3D seismic survey was used for much of the analysis (Figure 1). The survey was acquired in 2005 and encompasses all the wells listed above. Permafrost, Gas Hydrates, Shallow Gas In the Storms area the depth to base of permafrost varies from approximately -1500 ft. SS in the west to -2000 ft. SS in the east. The base of permafrost is poorly imaged on the Storms 3D because of permafrost's transitional nature and low fold at those depths. / The USGS Open File Report #2004-1454 by Timothy S. Collett indicates the Storms 3D, the NE Storms Unit, and the surface location for the Hailstorm #1 lie just southeast of the Eileen gas hydrate trend (Figure 2). None of the wells within the Storms 3D area, particularly the Hemi Springs Unit #3 well that is 2.5 miles southeast of the Hailstorm #l, encountered gas hydrates. Since gas hydrates have similar acoustic properties to permafrost, seismic is not useful for direct detection. Seismic data can be used to identify gas bearing sands that intersect the base of the permafrost and have the potential to form hydrates. 3D seismic data from the Storms survey (Figure 1) was used to further evaluate the presence of potential shallow hazards. To investigate the possibility of shallow gas bearing sands at the Hailstorm #1 location a structure map of the base of permafrost (Figure 3) was converted to a time horizon using • • velocity surveys from wells within the survey. Figures 4 and 5 show the base of permafrost time horizon on Inline 3757 and Xline 5897 through the Hailstorm #1 location. Amplitudes were then extracted for that time horizon. The resulting amplitude map (Figure 6) shows a series of NW-SE striking events that intersect the base of permafrost and represent reflectors dipping to the northeast. There is very little change in these amplitudes across the survey suggesting they represent lithologic changes and not the presence of hydrocarbons. In the Hemi Springs Unit #3 the interval just below permafrost is mostly shale with a few interbedded sandstones and conglomerates. There were no oil or gas shows in this interval in the Hemi Springs Unit #3. The amplitude map does display a relatively high trough amplitude near the location of the Hailstorm #1 (Green Horizon, Figures 4 and 5). This probably represents a sandy interval similar to those seen in the Hemi Springs Unit #3. This event was mapped to see if a structural trap was present or if the there was an amplitude anomaly suggesting the presence of hydrocarbons. Figure land 8 are time structure maps on the Green Horizon. They show a possible trap northwest of the NE Storms Unit. It is possible that the trap could include the Hailstorm #1 location if the trap was very large, extending beyond the Storms 3D. The amplitude map of the Green Horizon (Figure 9) displays a very patchy distribution of amplitudes that do not conform to structure and probably represent changes in lithology and not the presence of hydrocarbons. The amplitude map also shows evidence of an "acquisition footprint" that must be taken into account in the interpretation. Faults The current interpretation of the seismic survey does not show any shallow faults that will be intersected by the drilling of the Hailstorm #1. At depth, the wellbore could cut a fault at approximately the LCU (-8300 SS). This fault does not extend above the HRZ. Pressure Analysis of well data and seismic velocities indicate that the Hailstorm #1 well will penetrate a normally pressured section from spud to final TD. Mud weight and sonic log data from the Hemi Springs State #l, Hemi Springs Unit #3, and the Sequoia #1 were compared to seismic velocities from the Storms 3D survey. The comparison is also made to the Hailstorm #1 location and shows that the well should penetrate a normally pressured section. Figure 10 shows well and seismic velocity data from the Hemi Springs Unit #3 well which is 2.5 miles southeast of the Hailstorm #1 location. On the left graph mud weights from the drilling of the well are plotted versus depth (measured from seismic datum = 0'). On the right graph sonic interval transit times (ITT) are plotted versus depth. The nearest velocity analysis from Storms 3D survey, converted to ITT, is plotted with the sonic log. There is a good correlation between sonic and seismic ITT. The sonic ITT shows a normally pressured, hydrostatic gradient from the base of the permafrost to the Ivishak. The exceptions to this gradient are the organic rich shales of the Brookian, HRZ, and Kingak which are lower velocity due to their lithologic composition. The mud weights also suggest a normally pressured section with values between 91bs/gal and 11 lbs/gal. • Figures 11 and 12 are similar plots for the Hemi Springs State #1 and the Sequoia #1. Both wells show normal pressure gradients. Figure 13 is the ITT plot for the Hailstorm #1 location. Three nearby velocity analyses are plotted along with the sonic log from the Hemi Springs Unit #3. Figure 14 shows the Hailstorm #1 seismic ITT plotted with seismic ITT from Hemi Springs Unit #3 and Hemi Springs State #1. These data suggests that the section at the Hailstorm #1 should be normally pressured similar to that found in the Hemi Springs Unit #3 and Hemi Springs State #1. Conclusions Our evaluation of this data shows no indications of apparent drilling hazards or risks. / The analyses of this data are not definitive, however. Therefore, PNRA will work on the assumption that the possibility of encountering drilling hazards exists and work to establish drilling processes to mitigate those risks. iizn. -~~ ~ ... - PBU ., .,~- 19. --PBU B:~-~~__.. ..~~,,..:'-ao Pf~^•I n7-'~4A,-^oo -~~' .:..~.~.o~~n~o^F-4!SRI11f1-CYIA~n ,n on-J2¢ ~ ~ pBPBU Z-18 11 f PBU W-07~ ~rNU r-2o ~P6u ,,rIPBU Y-31 IY-1Ran__~PBU A-._ROPBU B-28AU B- 7, 9U OF 38:.. _7^_ - •• 8~BU A-39"O'ooii PBU DS07-04'- PBU DS02-14~ "IPE v u•ur " ~~ „PBU r-18 `PUT RIVER 33-1113 ~ ' B-23...,x,,. _Jr_ Fd~ PRUDHOE BA JU P-13 PUT RIVco n+>RII R-zF~oA ".. .~'r %-78^^ ^-~~.:; .RI Kuparuk River Unit 134 KUi ~ ~.,.S E EILEEN ST-11 BJU P-173U FPBU Y-2csx"r~" Y-~' •~-• -""~"" 02APBU PWD _ ~ °.'

Safe ~ Drilling of Wells Containing Hydrogen Sulfide as stipulated by 20 AAC 25.065(b) of the Alaska Oil and gas Conservation Commission Regulations. (Note: As of 2!4!00, API no longer lists API standard RP 43, referenced by the AOGCC. A revised standard is currently being developed) The forecast geology and near by drilling history indicates hydrogen sulfide is highly unlikely to be encountered in quantities dangerous to personnel or equipment. However, since there is no absolute assurance that hydrogen sulfide will not be encountered, this contingency plan provides for early detection and suspension of drilling operations before hydrogen. sulfide would be dangerous to personnel or equipment. Further, the plan provides for orderly evacuation of personnel, and protective equipment for those who may be required to shut in a well. Should hydrogen sulfide be encountered, the plan includes steps to safely handle the situation. IL Physical Properties of Hydrogen Sulfide H2S is a colorless, transparent gas with characteristic rotten egg odor. The disagreeable odor of H2S occurs only at relatively low concentrations. Those who have been rendered unconscious from high concentrations and survived, reported that they did not notice the rotten egg odor, but rather that it had a sickening sweet odor. H2S is a deadly and extremely toxic gas. H2S is readily dispersed by wind movement. H2S burns with a blue flame, producing S02, which is also a toxic gas H2S is flammable in the range of 4.3 to 46.0 percent in air. H2S has a vapor density of 1.189 (compared to 1.00 for dry air). Therefore, H2S is considered heavier than air and in concentrated form may collect in low places. H2S is highly corrosive to certain metals Doyon Drilling Inc.

Title: Hydrogen Sulfide Contingency Plan ~ 2 ~ Page 4 of 10 Author: Mike Peters Owner: HSE Director H2S is readily soluble in petroleum hydrocarbons and is soluble in water at room temperatures, at the ratio of three volumes of water. Such things as heating and agitation of the water will reduce the concentration. This solubility and the effect of heat can account, for example, for open drainage ditches evolving dangerous amounts of H2S during the heat of the day in cases where there was no significant amount found during the cool morning hours. III. Physiological Effects of Hydrogen Sulfide There are three principal effects from exposure to H2S: 1) The irritant action of high concentration on the mucous membrane 2) The effects on the eyes that may result from repeated exposures to low concentrations as well as short exposures to high concentrations 3) The more significant effect -paralysis of the respiratory nerve endings for exposure to high concentrations of 500 to 700 ppm or more Eyes can be affected by H2S exposure. It is believed that the effect on the eyes is due to the. caustic action of sodium sulfide formed by interaction of the H2S and the alkali of the cells in the presence of moisture in the eyes. Symptoms and effects of exposure to the eyes that have been reported include • Blurred vision, as though viewing objects through a silk screen • Appearance of colored rings around street or other lamps • Car lights which appear to be dumbbell shaped, blurred .and surrounded by colored halos • Red and inflamed eyes somewhat resembling "pink eye" • The eyelids may go into spasms and are difficult to open. These symptoms may disappear overnight or may persist into the next day. Hydrogen sulfide may have a slight anesthetic effect on the eyes. Often the symptoms do not occur until the 2"d to 4m day of exposure. Estimates of minimum concentrations of H2S that are required to cause eye effects are reported ranging from 4 to 25 ppm. Aside from the irritant effects on the eyes, the principal mode of entry into the body is through the lungs. Skin contact even in high concentrations is not considered significant. It has been reported that a perforated eardrum can be a roui~of significant exposure. There is less resistance to outside atmosphere via the perforation than via the breathing apparatus; and therefore, it is reported H2S can be inhaled through the ear under such circumstances. Earwax and earplugs offer little protection. Persons seriously exposed to H2S but who recover may suffer some lung irritation that can lead to pulmonary edema or bronchial pneumonia. The. systematic effects for absorption of H2S in the blood stream via the lungs is by far the most significant effect. Under normal circumstances, when absorbed into the blood stream, H2S at low concentration is oxidized rapidly to pharmacological inert compounds such as thiosulfate or sulfate. When the amount absorbed into the blood stream exceeds that which is readily oxidized systematic poisoning results in a general action on the nervous system; labored respiration occurs shortly, and respiratory paralysis may follow Doyon Drilling Inc.

Death then occurs from asphyxiation, unless the exposed person is removed immediately to fresh air and breathing is stimulated by artificial respiration before heart action has ceased. In high concentration of gas the mechanics of this respiratory paralysis (formerly thought to involve a chemical reaction with the respiratory enzymes or with hemoglobin or both) are now believed to be reflexes resulting from irritation of the carotid sinus. Moderately high concentrations on the other hand cause an arrest of breathing, but not respiratory paralysis, after over stimulation of the respiration center. In such cases resumption of breathing would probably occur after removal from exposure, even without artificial. respiration. Recovery from acute exposure to H2S is usually considered complete, although sometimes prolonged for as much as several weeks, unless there has been damage to the brain due to prolonged oxygen deficiency. Transient and sometime permanent psychic or nervous changes may be encountered if there has been. damage to the brain. In cases of chronic exposures, symptoms that occur include headaches, dizziness, nausea or gastrointestinal disturbances, dryness and sensation of pain in the nose, throat and chest, and coughing, Physioloctical Response to Various Concentrations of Hydrogen Sulfide Information as to the concentrations of H2S that are detectable by smell vary considerably. Following are some general guidelines as to the detection of H2S as they relate to parts per million (ppm): • 0.13 ppm: Minimal perceptible odor • 4.60 ppm: Easily detectable, moderate odor • 10 ppm: Beginning eye irritation • 27.0 ppm: Strong, unpleasant odor, but not intolerable. • 100 ppm: Coughing, eye irritation, loss of sense of smell after two to five minutes • 200-300 ppm: Marked conjunctivitis (eye irritation) and respiratory tract irritation after one hour of exposure • 500-700 ppm: Loss of consciousness and possible death in thirty minutes to one hour • I00-1000 ppm: Rapid unconsciousness, cessation (stopping oe pausing) of respiration and death • 1000-2000 ppm: Unconsciousness at once, with early cessation of respiration and death in a few minutes. Death may occur even if individual is removed to fresh air at once Doyon Drilling Inc. PAPER COPIES ARE UNCONTROLLED. THIS COPY VALID ONLY AT TIME OF PRINTING.

Physical Properties of Sulfur Dioxide Sulfur .Dioxide is colorless gas or liquid. It has a pungent odor and is not flammable. It is formed when hydrogen sulfide is burned. The vapor density is 2.264 (compared to 0.0 for air). Anhydrous sulfur dioxide is not corrosive to steel or other commonly used metals. In moist environments, it combines with water to form sulfurous acid, but it only very slowly oxidizes to sulfuric acid. In the presence of water, sulfur dioxide is corrosive to steel and other metals. Concentrations of 6 to 12 ppm cause immediate irritation of the nose and throat. The average individual can detect a level of 0.3 to 1 ppm possibly by taste rather than by sense of smell V. Physiological Properties of Sulfur Dioxide Sulfur dioxide is intensely irritating to the eyes, throat, and upper respiratory system. Its. irritant properties are due to the rapidity with which it forms sulfurous acid on contact with moist membranes. An estimated 90% of all S02 inhaled is absorbed in the upper respiratory passages with only slight penetration in the lower respiratory tract. Sulfur dioxide exerts its toxic influences on humans through acute and possible chronic effects. Acute symptoms effect the eye, mucosol, and upper respiratory tract irritation. Potential chronic effects include nasopharangitis, reduction of pulmonary function and increased resistance to airflow. Chronic effects of sulfur dioxide exposure may result from repeated bronchoconstriction. While bronchoconstriction is not itself a chronic effect, it is believed that continual exposure can lead to substantial permanent pulmonary function due to the aging process. VI. H2S Detection/Monitoring and Equipment a. Although hydrogen sulfide is not expected, monitoring is needed to alert personnel immediately to the presence of hydrogen sulfide in the event it is encountered. To provide the necessary warning, there are H2S detectors placed at the shale shaker, pit room, bell nipple, cellar, and on the rig floor. Warning lights and alarms will alert all crews if any of the detectors sense H2S. An amber warning light will come on at a low reading of 10 ppm. A high level siren will come on at 20 ppm. H2S detectors will be calibrated before spudding, when BOPs are tested, when a State Inspector requests it, and at least every six months. b. Portable H2S monitors will be available for spat-checking of H2S. These will be located in the doghouse on the rig floor. All monitors will be calibrated monthly by the rig electrician. Below the protective casing, daily mud checks will be made to determine the presence of sulfides in the mud. d. Two signs of warning the possibility of encountering H2s will be displayed on location. One at the entrance of the rig, the other at the entrance to the pad. Doyon Drilling Inc. PAPER COPIES ARE UNCONTROLLED. THIS COPY VALID ONLY AT TIME OF PRINTING.

Special Operations a. Corin During drilling operations below surface casing, it may be decided to core, which takes on critical complexities if attempting to do so in a sour well. Specific coring procedures will be issued for cutting cores. The following practices should be followed during coring operations. After a core has been cut, circulate bottoms up and monitor mud for H2S. If coring rate indicates porous zone has been cut, put breathing equipment on 30 minutes before bottoms up reaches surface. 2. Unless the hole conditions (and/or H2S detector) indicate extreme conditions, put on breathing equipment 10 stands before core barrel reaches the surface. XII.

Drop back to zero with a 3*1100* dogleg Summary of Results: Day 1, February 3, 2006 Sperry drilling services personnel arrive on location. Start up directional paper work for the job and measure the directional tools for BHA Made up BHA and orient motor for offset. Day 2, February 4, 2006 R.LH with BHA for the correction run. We had to reamlwash from 5048' to 5336' to we coulf get back to bottom. I start the drop section according to plan with a 15' 8t a 20' set slide a~ 180* toolface gravity. After seing my slide and notice that the motor was not very strong for performance I start sliding 25' set and full single at 1 SO* toolface gravity. I would of P.O.O.H to set the motor higher but after talking it with the company rep and his upper personnel they say to not worry because iYs a big target and just continue to slide to drop angle so we get veritcal.The drilling is averaging around 30 to 60'ltrr and thaYs taking in all the hard formation that we had to drill. Drilled from 5336' to 5512'. Day 3, February 5, 2006 Drilling ahead from 5563' to 6112' with the continue of dropping are angle to 0*. Pm sliding full single at 180* Toolface, the motor performance sfill only gives from 1 * to 3 *1100'. Day 4, February 6; 2006 Drilled to 6144', circulate the hole clean and survey. Star pulling out of hole and reach the depth of 5220' we start pulling tight up to 46k over string weight so make up kelly and start reaming out and washing the tight hole up to 5212'. The rest of the trip went good but when we reach the Hw we notice that the drilling pipe tally was out by being 31.05' deeper then we had. We correct the survey back with the 31.05' that encounter so the survey match the wellbore depth. We pull back to surface to check are MWD tool after having some problem with taking survey during the BHA 1 run. They end up laying down the tool and send it back to the shop for a full test and troubleshooting. We pickup the MWD tool and start R.I.H. Day 5, February 7, 200b Started the day by finnishing are trip back to bottom. Slide from 6175' to 6520' according to toolface needed in Magnetic to turn the wellbore around to the south East so the wellbore gets back closer to original plan. Drill from 6144' to 6971'. Day 6, Febn~ary £, 2006 Page 3 Sperry-Sun Drifting Sen%lces I' , Pioneer Natural Resourr;es Alaska Hailstorm Drill to 7131' and I slide to locate the wellbore to the south East so the well path would come closer to plan. We circulate the well and did a short wiper trip back to 43(10'. We had a tight spot F(6337' to 6240' and circulate and ream through it and Finnish are trip. Drilled from 7131 ` to 7764'. Day 7, February 9, 2006 We drilled from 7764' to 8209'. We start pulling out of the hole for a short wiper trip and we hit a tight spot at the MD of ?600' and 7660', we pull up to SOK over string weight. Ream the tight spot and circulate through it and continue with the wiper trip. Running beak to bottom went good. When an bottom we circulate and ream the last single prior to get back drilling. Day 8, February 10, 2006 We drilled from 8209' to 8945', they was no sliding needed as required by geologist. The word is to rotate to TD. Day 9, February 11, 2006 Drilt from 8945' to TD of 9525'. Circulate bottom up and they decide to drill and other 20'. Circulate hole clean again and P.O.O.H to lay down tools. '' Day 10, February 12, 2006 Finnish to trip out of hole and lay down tools.

Orient weflbore according to new plan for the correction run and drop the angle back to zero. RESULTS; Make up BHA and trip the hole for correcting the wellbore. When reach bottom at the depth of 53551 started with a 15' slide ~ 180* toolface gravity, the next joint t slide 2d' at 180* toolface gravity all by expecting to get a 7 are 8* build rate motor pertormance but when i seen the result and k was only giving 1.5* to 2*/100' build rate I start to slide full single at 180* tootface. The result was not very succesfull and I brought the idea to the company man of maybe P.O.O.H to set the motor up to be able to uptain big~r dogleg, he told me that Pioneer won' t to worry about it and just keep sliding until we get vertical because the target is big. I just continue with sliding everything and trying different things to help the drop rate. We Finnish off at the depth of 6144' according to pipe taly and circubte to clan hole prior to trip out for a wiper run. When we reach the depth of 5224' the hole start to pull tigh up to 40K over pull on string weight so we made up the kelly and start working are way out by reaming and washing the tigh spot all the way back to 5212'. We notice to that are pipe tally was out by 31' by having one more joint in the hole that we had counted when R.I.H. The en'or was made when the rig was R.I.H and they did not notice a joint of Dp on top of the Hw. We fix the survey by adding the depth of that single back on top each survey. ii ~~ i~ s 1 _.,_ _- ....___..._.~.....____._...-_..._. _.-__ i. e ~f s . .

Orth, R. ' McNiel Date: 2/12/2006 Well: Hailstorm #1 Hole Section: Intermediate What went as, or better than, planned? ' Great detection. From the time the MWD engineers arrived on location to picking up the first MWD tool was 7 hours. What experienced difficulty? The MWD tool had difficulty determining if the pumps were on or off. This was caused by the pressure downhole not building up, or bleeding off quickly. With care during pump cyclings this problem was neutralized. After the drillstring became stuck and was jarred on while tripping out of the hole, the MWD tool failed at surface post run 100. Causing 7.5 Hours of downtime because of no availability of a backup tool. Recommendations? With using high chloride mud systems at low pressure fosses, lower the MWD delta pressure lower than normal (3750p to a 2750p). Were there any innovations and/or cost savings realized on this well?
