Brief Well Summary The A-29 well developed a leak at the choke and was shut down. During this shutdown it was discovered that several valves would not seat and had to be greased to get them to seal. A decision was made to shut the well in until the rig was available to skid over the well to change the valves. The rig itself would not be utilized other than the winch line, but needs to be over the well for alignment purposes to remove and replace affected valves. Brief Procedure: 1. Move Monopod Platform Rig#56 over Well Slot A-29. 2. Set BPV. 3. Disconnect flow line. 4. Remove treecap,cross and three valves. Replace same with like in kind. 5. Re-connect flow line. 6. Remove BPV. 7. Return to injection. Attachments: 1. As-built Well Schematic 2.

Unocal notified the Commission on February 23, 2009 that Trading Bay State A -29RD exhibited a significant pressure increase in the well's tubing - casing annulus. Pressure was detected on February 21, 2009 and the well was immediately shut in pending diagnostic tests. Union submitted a request dated February 25, 2009 to perform a 30 -day injection test followed by a static temperature survey to confirm casing integrity. At the Commission's request, Union proceeded with the temperature survey without the 30 -day injection. The temperature survey performed on March 18, 2009 confirms the injected fluids are exiting the well at the perforations and all injected fluids are contained within the injection interval authorized by AIO 12. Union also performed a wellhead inspection and confirms that there are no integrity concerns and that pressures are contained within the wellbore. An aquifer . exemption is in effect for all aquifers lying directly below Trading Bay Field [40 CFR 147.102(b)(2)(iv)]. Based on the diagnostic test results, Union has elected to perform no corrective action at this time on Trading Bay State A -29RD. The Commission believes that the well's condition does not compromise overall well integrity so as to threaten the environment or human safety. The Commission's administrative approval to inject in Trading Bay State A -29RD is conditioned upon the following: i 1. Injection is limited to WATER ONLY; AIO 12.002 • • March 23, 2009 Page 2 of 2 2. Union shall monitor and record tubing, inner annulus, and outer annulus pressures and injection rate daily; 3. Union shall submit to the Commission a monthly report of well pressures and injection rates; 4. Union shall perform a temperature survey at intervals not to exceed every 2 years in lieu of the mechanical integrity test as outlined in Rule 5 of AIO 12 to demonstrate continued production casing integrity; 5. Union must immediately shut in the well and notify the Commission if there is any change in the well's mechanical condition; and 6. After well shut in due to a change in the well's mechanical condition, Commission approval shall be required to restart injection. 7.

If the notice was mailed, then the period of time shall be 23 days. An application for reconsideration must set out the respect in which the order or decision is believed to be erroneous. The Commission shall grant or refuse the application for reconsideration in whole or in part within 10 days after it is filed. Failure to act on it within 10 -days is a denial of reconsideration. If the Commission denies reconsideration, upon denial, this order or decision and the denial of reconsideration are FINAL and may be appealed to superior court. The appeal MUST be filed within 33 days after the date on which the Commission mails, OR 30 days if the Commission otherwise distributes, the order or decision denying reconsideration, UNLESS the denial is by inaction, in which case the appeal MUST be filed within 40 days after the date on which the application for reconsideration was filed. If the Commission grants an application for reconsideration, this order or decision does not become final. Rather, the order or decision on reconsideration will be the FINAL order or decision of the Commission, and it may be appealed to superior court. That appeal MUST be filed within 33 days after the date on which the Commission mails, OR 30 days if the Commission otherwise distributes, the order or decision on reconsideration. As provided in AS 31.05.080(b), "[t]he questions reviewed on appeal are limited to the questions presented to the Commission by the application for reconsideration." In computing a period of time above, the date of the event or default after which the designated period begins to run is not included in the period; the last day of the period is included, unless it falls on a weekend or state holiday, in which event the period runs until 5:00 p.m. on the next day that does not fall on a weekend or state holiday.

The survey confirms that all fluid was being injected into the zone of interest. I apologize for the delay in submitting this survey, but we had some surface equipment problems that temporarily prevented us from running wireline surveys. During the time that we were waiting to get the equipment repaired we were able to perform an inspection of the A-29RD wellhead and confirmed that there are no integrity issues in the wellhead. I have attached a summary of the wellhead inspection. As you consider the status of A-29RD you may want to consider that while this well only has one string of tubulars across the completion interval, the well is not a true monobore due to the fact that there are multiple strings of casing isolating the shallow water and hydrocarbon bearing intervals. If you have any questions or would like to discuss this well in more detail please contact me at 263-7658. I look forward to your recommendations on how best to move forward with plans to utilize this wellbore. «A-29RD Mar 09 vs Jun 07 Temp Log Comparison.ZlP» «A-29 wellhead report.pdf» 3/23/2009 • • etrron ~-. , Chevron Wellhead Report Platform or Field: Monopod Well Number: A-29 Date: 3/12/2009 Casin Pro ram: 20 X 16 X 13 3/8 X 9 5/8 X 4 1/2 Wellhead Description: Starting head, OCT, 2 step unihead, 21 1/4 2M API FE X 20 SOW, has 16" and 13 3/8 casing hung off in head.

Following the completion of the 30 day test, a static temperature survey will be run. The purpose of the test is to confirm casing integrity with the goal of returning the well to long term injection. Well A-29RD (API # 50-733-2024-501-00, PTD #202-004) was shut-in shortly after midnight on February 21, 2009, when casing pressure increased from zero to 1,800 psi. The well remains shut-in. This well typically injected 9,000 BWPD or 75% of the total Monopod injection of 12,000 BWPD. Without this well, it has been necessary to shut-in the entire Monopod waterflood. Well A-29RD was redrilled as an injector in 2002. The well has a bottom-hole location on the northern nose of the McArthur River Field. The well provides pressure support to offset producers A-15RD2 and K-13RD2. A recent pulse test confirmed that A-29RD positively benefits both producers. The well is unique in that it is completed as a monobore completion across the perforated interval. A copy of the schematic is attached to this request. Following is the proposed procedure for bringing the well back on injection. 1) Obtain permission to inject. 2) Inject into the well until the injection rate has stabilized. (Limit the length of the test to 30 days.) 3) Run a follow-up temperature survey. 4) Request Administrative Approval to continue injection depending on results of the survey. If Administrative Approval for continued injection is granted, the daily rates and pressures will be monitored and temperature surveys will be repeated every two years.

The subject well was completed as a Class II enhanced recovery (EOR) well in August 2002. The casing x tubing or inner annulus (IA) of the well does not extend to near the injection zone as on a traditional completion. The Commission approved this design deviation while the well was being drilled, however in consideration of the design compron1Ìse specific MIT test requirements were established. The requirements included a pressure test of the 4-1/2" tubing/liner using a wireline set plug and a temperature survey on a 2-year schedule. Due to the potential risk of not being able to recover a wire line set plug and the inability to replace voidage in the reservoir, Unocal is requesting that the pressure test requirement be waived. Unocal intends to perform the temperature log as required. Your proposal is accepted, however additional integrity demonstrations may be determined necessary based on Unocal's analysis of the planned survey and comparison with prior surveys. When you submit the latest survey information, you should include an interpretation of the surveys. Your discussion should also address the "character" of the log which has been attributed to the wellbore crossing the Trading Bay Fault. We look forward to your assessment of the surveys. Please keep us advised of when the work will be conducted. Sincerely, ~~~4 Thomas E. Maunder, PE Sr. Petroleum Engineer Unocal Alaska Resources Unocal Corporation 909 West 9th Avenue, P.O. Box 196247 Anchorage, Alaska 99519-6247 Telephone (907) 276-7600 UNOCAL8 FIB 2 5 2005 February 22, 2005 Alaska Oil and Gas Conservation Committee 333 W ih Ave. #100 Anchorage, Alaska 99501-3539 Attn: Tom Maunder Re: Monopod A-29 RD MIT Dear Mr. Maunder: The original Sundry approval (No. 302-242 dated August 1, 2002) for injection well A- 29RD contained the stipulation that if the well should cease production, offset producers K-13RD and A-15 RD2 be shut-in. The precise quote is as follows: "The inability to replace reservoir voidage (i.e. operate well A-29 RD) will require the production wells accessing that area to cease production until the reservoir injection can be restored." Offset producers K-13 RD and A-15RD currently produce over 720 BOPD. This represents a significant portion of the TBU and TBF production. Well A-29 RD is scheduled for an MIT in 2005. Due to the critical nature of this well, Unocal would like to request that the standard procedure be waived for this well and that a temperature survey be run to confirm that injected fluid is entering the desired zone. The risk of setting a plug in the tubing to conduct a standard MIT test represents too great a risk to offset production. Unocal has experienced problems pulling plugs following MIT's in the past. A baseline temperature survey was run in well A-29 RD on August 8, 2002 followed by a dynamic survey on November 6, 2002. Both of these surveys will provide a basis for comparison to verify that injected fluids are entering the Hemlock reservoir and are not exiting the tubing into any other reservoirs. Unocal will conduct a standard MIT on the 7"x 9/5/8" casing annulus, by pressure testing the annulus to 1,750 psi. Unocal requests your concurrence that a temperature survey will satisfy the requirements for an MIT of the tubing in well A-29 RD. r;~ XalK Steve Lambert Advising Reservoir Engineer cc: Dave Cole Larry Greenstein ,if TOC at 7350' MD ~ « . . .. . ;:~: :~:~ /5711' TVD . . ~ - ... .. . . . . . ... . . . . .. .. :::: :::: ",". ,,'." ... . . . . .. . ... . .

What you are proposing is acceptable, however additional work may be necessary depending on the determination from your analysis of the new temperature survey and comparison with the prior surveys. In addition to submitting a plot of the temperature surveys, your submission should also include Unocal's interpretation of the survey(s). I have looked at the prior surveys and according to the notes I have, some of the "extreme" character evident is attributed to crossing the Trading Bay fault.

This well was recently drilled as a water injector and passed an MIT for the tubing (3,500#) and casing (1,720#) on August 6,2002. Since this well does not have a packer, additional test's have been performed to-document placement of injection water into the intended production reservoir. 411~ :L//J/O$ The temperature survey is plotted along with the baseline survey done August 8, 2002. A-29RD had been placed on injection for 45 days at approximately 7,500 bid. The well was shut in for 12 hours before running the test. The survey shows no significant cooling anomalies above the TBD Hemlock reservoir. The EOR zone Hemlock perforation is represented by 45° cooling event at 12,912' MD in the data. I have enclosed plots of the temperature surveys (in Measured Depth and TVDSS) and a current well bore schematic.

The only slight anomaly I see in the survey is between 6000' - 7000' MD. This is the area where we crossed the TB Fault and drilled several hundred feet of coal. We plan to start injection as soon as our surface injection line hook up is completed (hopefully tomorrow sometime). We will be monitoring pressures on the tubing and annulus as we do on other injection wells. r--"~, jection is started to submit this temp I would like to wait until the rerun of the temp surve\f survey and the rerun survey, if that's OK with you. «A29RDQuickTempSurvey081202.zip» Res.

Shane Hauck was the Unocal representative in charge of the test, which was performed in a safe and proficient manner. The pre-test pressures were observed to be stable at 0 PSI. The standard annulus pressure test was then performed with the tubing pressure maintaining 3500 PSI during the 30 minute test. The annulus pressure dropped 60 PSI during the 30 minute test. Thepress1.lre test was extended an additional 30 minutes to. further determine mechanical integrity. The annulus pressure dropped 20 PSI in the second 30 minutes and stabilized at 1700 PSI, passing theMIT.

Harrison Drilling Manager U nocal PO Box 196247 Anchorage AK 99519 Re: Trading Bay Field A-29 RD Union Oil Company of California (Unocal) Permit No: 202-004 Surface Location: 1623' FSL, 570' FEL, S4,T9N, R13W, SM Bottomhole Location: 4398' FSL, 1284' FEL, S16, T9N, R13W, SM Dear Mr. Harrison: Enclosed is the approved application for permit to redrill the above referenced well. A spacing exception as required by Rule 5 of Conservation Order 80 was issued May 22, 2002 for the proposed well. The 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. 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 note that disposal of any fluids generated from this drilling operation that are pumped down the surface/production casing annulus of the Grayling G-22 well must comply with the requirements and limitations of 20 AAC 25.080. Approval of this permit to drill does not authorize disposal of drilling waste in a volume greater than 35,000 barrels through the annular space of a single well or to use that well for disposal purposes for a period longer than one year. Unocal further requested waiver of the requirements of 20 AAC 25.412 (b) where the distance between the top perforation and the packer is required to be 200' or less. In A-29RD, the planned configuration of the well requires the packer be placed approximately 4,200 feet above the uppermost perforation. The 200- foot distance specified in our regulations allows a casing by tubing annulus to exist within relative proximity of the injection perforations. This allows monitoring of the annulus, which ensures protection of freshwater sources and isolation of injected fluids to the intended injection zone. Although all aquifers in McArthur River and Pennit No: 202-004 May 31,2002 Page 2 of2 Trading Bay Fields have been exempted by EPA (40 CFR 147.102 (b)(2)(ii) and (iv), the Commission still remains concerned that injected fluids are limited to the intended reservoir stratum. For A-29RD, the Commission requires a cement evaluation log across the cemented interval at the bottom of the well (from approximately 13418' to 12,000' MD) and across log- determined confining zones above the 4 ~-inch liner top. Unocal must perform a normal annulus pressure test to demonstrate integrity, and conduct a full bore pressure test prior to perforating. U sing temperature surveys to demonstrate well integrity is an acceptable practice. A baseline temperature survey must be acquired prior to placing the well into service. A second temperature survey must be conducted after the well has been in service for approximately 60 days. The Commission will determine the interval for subsequent temperature surveys after examining the initial surveys. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25 035. Sufficient notice (approximately 24 hours) must be given to allow a representative of the Commission to witness a test ofBOPE installed prior to drilling new hole. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

Monopod A-29RD Hazard Analysis for APD 20AAC 25.005 (c) 4 (A) The Long and short strings have been shut in since August '83, and the latest slick line job on March 25, 1985 tagged solid fill at 2,412' and 597' inside long string and short string respectively, far above uppermost (dual) production packer at 7,360'. The abandonment plan is to cut long string at approximately 1900' MO and the short string at 500' and then backoff short string to approximately 1900' (below the fill). The potential hazard here is the trapped pressure below the fill that will be released when the tubing backoff is carried out. A hot tap tool will be ready on location to release trap pressure upon tubing recovery. j (B) Shallow kick off at 1800' gives a marginal kick tolerance, Le., 22.8 bbls to drill to 7000' TVO of 8- 1/2" hole using 9.2 ppg mud, 0.73 psi/ft fracture gradient and 8.3 ppg EMW pore pressure. Good drilling/tripping practice and reliable PVT equipment shall be able to mitigate this marginal kick tolerance. Another safe guard is that the 6" hole section can be started shallower if needed, without reducing TO of the well. ~/ (C) The Hemlock production in the area has an H2S content of up to 400 ppm. Prior to drilling the A- 15RO, a full cascade system and individual SCBA's will be in place. An H2S Safety Technician will service the equipment, conduct drills and refresh crew members in the proper use of the equipment.

The fracture gradient value of 14.1 ppg for the 9-5/8" proposed shoe at 1633' TVD is based on the FIT performed on A-15RD2 at 1183' MD. The actual fracture gradient for A-29RD should be higher due to the deeper KOP and the FIT on A-15RD2 was not a leak-off.

A separate Sundry Application (Form 10-403) was previously sent to you and approved on 1/4/02 (Approval #301-352) for the proposed abandonment of A-29 well. The planned kick-off depth at that time was 1100' but now the kick-off depth has been changed down to 1 800' . A-29RD will consist of approximately 7400' of 8-1/2" and 4300' of 6" holes drilled with oil based mud. Any liquid waste will be disposed in the annulus of Grayling G#22 well and the OBM cuttings will be disposed in Bruce#3 disposal well, transported via shuttle boat(s). A-29RD will be an injector drilled to the Northern Nose structure to support offtake from A- 15RD2 and K-13RD2. Wireline triple-combo logs will be run in the 8-1/2" hole section and an LWD run will be made on the last 6" bit run. Unocal requests a waiver for 20 AAC 25.412(b) "packer must be placed within 200' measured depth above the top of the perforations." The proposed 7" liner casing point will result in an injection packer above the top of the 4-1/2" liner top which is considerably higher than 200' above the top injection perforation (packer at 8800' and top perf at 13007'). This is due to the long distance that is required to be drilled from the initial KOP of 1800' to TD of 13418'. It would not be feasible to attempt to drill the 8-1/2" hole all the way down to near the top of the Hemlock at 13007'. This would result in too many days with the hole open even with oil based mud and hole stability would be a problem. Therefore, Unocal proposes to split up the hole sections such that neither the 8-1/2" or the 6" hole section will be open for a long period of time. However, this will result in the 4-1/2" x 7" injection packer being well above the perforations. Unocal proposes that a ~periodic temperature survey could be performed to verify that integrity exists between the injection packer at 8800' and the top perf at 13007'. This would be in addition to the normal requirement of a pressure MIT on the annulus above the packer. RECEI\/ED ORIGINAL tv'1 !\\f -'; 7 ')fjn? ¡ ir"".! ¡ ¡ ""~Vl... Alaska Oil & Gas Cons.

The well will be re- drilled to the Northern West flank of the northern nose Hemlock Structure as a water injector to support K-13RD2 and proposed A-15Rd producing wells. The "B" zone perforations were covered by debris or fill above uppermost perforations as well as more fill at 2,412' inside long string. The "A" zone was reported producing coal leaving a fill tagged at 597' MD in the short string. Upon retrieval of long and short strings, a 9-5/8" cement retainer will be set approximately at 1,900' to squeeze abandon the well. Prior to abandonment, the well should be able to be killed with 8.5+ ppg Filtered inlet water, however, we will be prepared for 9.8 ppg if need be. Application Form 403 covers the preliminary abandonment operations. Subsequently, a two string (13-3/8" and 9-5/8") window exit will be cut and two (2) sections of holes, Le.,8-1/2" and 6" will be drilled to TO prior to running 4-1/2" tubing completion for water injection. A separate Permit to Drill Application Form 401 will be submitted for the proposed redrill of A-29Rd.

Please consider the fotlowing corrections/additions to the application: 1 )The Form 10-401 section #18 has the incorrect top of the 7" liner, it should read top of liner at 900' MD/875' TVD instead of 0' MD/O' TVD. 2) The liner cement density for the 7" liner will not be all 15.8 ppg. There will be 1000' of 15.8 ppg tail slurry and the rest will be 12.0 ppg lead cmt in order to maintain good returns throughout the job and bring cmt up the top of the 7" liner at 900'. So, the corrected 7" liner cmt volume calculations will be as follows: 15.8 ppg tail = 3 bbls of shoe track plus 1000' x .02258 bbl/ft x 1.2 excess = 3 bbls + 27 bbls = 30 bbls or 168 cuft or 142 sx of 1. 19 cuft/sk tail /' slurry. 12.0 ppg tail slurry = 6510' .. 1000' tail.. 900' liner top = 4610' x .022,58 x 1.2 = 125 bbls or 702 cuft or 275 sx of 2.55 cuftlsk lead slurry. ,/",' The 20% excess calculation above may be altered depending on actual washout observed by dropping a mud marker on circulation at bottom. 3) The 4-1/2" liner cement volume needs to be adjusted. It is anticipated that no hydrocarbons will be present above the proposed Hemlock injection perfs. Unocal proposes to pump a lesser volume of cmt than the original APD of 617 cuft if no hydrocarbons are present in the intervals above the Hemlock. This would avoid circulating cmt above the liner top which would result in a risk of sticking the drill string and would cause an extra clean out trip. This smaller volume of cmt would also avoid the risk of losing returns into the proposed Hemlock completion interval. Unocal proposes covering the proposed top Hemlock perf of 11900' with 1000' ..//' of 15.8 ppg slurry. This proposed revision would result in a c~lculated cmt volume of 1.2 bbl of shoe track plus (12226' TD- 10900' TOC:! 1326') x .0153 bbUft of 6" x 4-1/2"// annulus x 1.2 excess = 1.2 +24.3 = 25.5 bbls or 143 cuft or 121 sx of 15.8 v' ppg 1.19 yield emt. 4) The proposed monobore design with the injection packer effectively being the liner top packer at appx 6310' needs a waiver from you because it will be much greater than 200' above the perfs. 10f2 r Or, ~ \J.Ç ç~ ,/' 2/28/0212:15 PM A-29RD APD corrections and additions ') ") There should not be any hydrocarbons from the 6310' down to the Hemlock perfs at 11900' but as we discussed on the phone, but this is not enough of a reason for you to grant a waiver for the packer being so far above the perfs. Unocal proposes to run a temperature log periodically to verify that the proposed 4..1/2" liner is not leaking above the perfs. If AOGCC concurs, then you will stipulate the frequency that this temperature log needs to be run while A-29RD is on injection.

By letter to the Department of Natural Resources (DNR) dated December 29, 2001, Unocal apprised the DNR of this agreement and copied the Alaska Oil and Gas Conservation Commission on the same. To reiterate, Unocal and Forest now share a common equity ownership of 53.20% and 46.80% respectively, in the oil-bearing horizons for both the TBU and TBF. Thus, irrespective of individual lease ownerships, the relative aligned interests inside the TBU and TBF are the same. Please let me know if you have questions regarding this transmittal.

This is disappointing since in the success case for A-15RD voidage replacement in the Northern Nose will be delayed. I have communicated this information to the Commissioners and Senior Staff. They share the disappointment, but have pointed out that there are still a number of questions to answer with regard to the Northern Nose. Therefore, we propose a meeting be arranged to review the presently available information on the Northern Nose oil accumulation. We view this as a follow on to the original meeting held in our office after the successful completion of the King Salmon well. We are open to a suggested meeting date, however Commissioner Seamount and myself will not be available the week of January 21 and he will be not be available the Friday preceding or Monday following. Please check with Jeff and any others who would be involved and get back to me with a suggested time. Good luck with A-15RD.

The abandonment plan is to cut long string at approximately 1 ,200' and the short string at 500' and then backoff short string to approximately 1,200' (below the fill). The potential hazard here is the trapped pressure below the filt that will be released when the tubing backoff is carried out. A hot tap tool will be ready on location to release trap pressure upon tubing recovery. (B) Shallow kick off at 1,100' gives a marginal kick tolerance, Le., 15 bbls to drill to 5,500' TVO of 8- 1/2" hole using 9.4 ppg mud, 0.78 psi/ft fracture gradient and 8.6 ppg EMW pore pressure. Good drilling/tripping practice and reliable PVT equipment shall be able to mitigate this marginal kick tolerance. Another safe guard is that the 6" hole section can be started shallower if needed, without reducing TO of the well. (C) The Hemlock production in the area has an H2S content of up to 400 ppm. Prior to drilling the A- 15RO, a full cascade system and individual SCBA's will be in place. An H2S Safety Technician will service the equipment, conduct drills and refresh crew members in the proper use of the equipment.

The Hazards Like many chemicals used in oil and gas drilling, oil-base mud can be hazardous to your health if handled improperly. When working with oil-base mud be aware of the following hazards: Oil-base mud is difficult to remove from the skin. Oil-base mud, and some of the chemicals used in it, can be quite irritating to the skin and eyes. Mist and vapor from oil-base mud, especially in the area around the shakers, can be irritating to the respiratory system. Oil-base mud is difficult to remove from clothes. If clothing is not properly laundered, mud residue in the material can cause skin irritation. How to Protect Yourself Always have the Material Safety Data Sheets (MSDSs) available on location for all chemicals that you handle. Read and follow all instructions on the MSDSs. Use the Personal Protective Equipment (PPE) described below. Avoid unnecessary contact with the mud. Wipe mud off your skin as soon as possible and wash with soap. If mud soaks through your clothes, change and wash as soon as possible. Use good personal hygiene, wash thoroughly after each tour. Oil-base mud is very slippery. Keep decks and stairs clean. Personal Protective Equipment (PPE) Eyes - chemical splash goggles. Body - use leak-proof clothing such as TyveÕdisposable coveralls in warm weather, slicker suits in cold weather. Hands - use leak-proof gloves made of nitrile, neoprene or equivalent Feet - wear leak-proof boots made of neoprene, urethane/vinyl or equivalent. Respiratory -use a NIOSH-approved P95 half-mask disposable or reusable particulate mask for mist/aerosol; use a NIOSH/MSHA- approved organic vapor respirator for vapors. Skin Care The most common health problem with handling oil-base mud is dermatitis or skin irritation. The following 3-step program is designed to help you prevent dermatitis -Protection - before contact with the mud apply a barrier cream to areas that are not easily covered by some other form of PPE. Use a barrier cream specifically designed to protect against oil-based or solvent hazards. Barrier creams should be used in addition to the P P E mentioned above, not as a substitute for it. -Cleaning - wash frequently, and use a soap designed to remove oil and grease from skin, such as the waterless soap preparations used by mechanics. Do not wash your skin with diesel or rig wash. -Reconditioning - contact with the mud and frequent washing of the skin can result in loss of the skin's natural oils and moisture. To prevent dry, chaffed, and irritated skin apply a reconditioning skin lotion after work and as needed. Over-the- counter hydrocortisone cream may be used to relieve minor skin irritation. Follow instructions and precautions provided by the manufacturer. If left untreated minor skin irritation can progress and result in intense itching and blisters which can become infected. Cases of severe dermatitis, especially if infection is suspected, should be referred to a doctor immediately. Laundering Recommendations Be sure that your work clothes are clean before wearing them. For clothing that is heavily soiled with oil-base mud this will require special laundering procedures. Laundering procedures must be adapted to available equipment and conditions; however ,the following suggestions have been proven to be effective: -Do not overload washers. -Designate one washer for washing only muddy clothes. Clothes which are no soiled with oil-base mud should be washed in a separate washer. -The washer used for muddy clothes should be cleaned periodically by running a wash cycle with hot water and detergent only (no clothes). -Run muddy clothes through at least 2 wash cycles using hot water and regular laundry detergent. Additional cycles may be necessary for extremely muddy clothes. -If repeated washing is not possible or practical, pre-soak muddy clothes 1-2 hours in a laundry detergent solution before laundering. This can be done in a container such as a clean 55 gal drum or large plastic trash can. - Workers who handle muddy clothing should observe the precautions outlined above. ) ) II HMIS Hazard Ratings* I I Product II Function II Health II Flammability II Reactivity II PPE ** I VERSACLEAN Mineral oil-base drilling fluid *1 1 0 J VERSADRIL Diesel oil-base drilling fluid *2 2 0 J VERSACOAT Surfactant *2 3 0 J VERSAMUL Basic Emulsifier package 1 2 0 J VERSAMOD Rheology modifier 1 2 0 J VERSATHIN Defloculant 1 2 0 J VERSAWET Wetting Agent 1 1 0 J VERSA HRP Viscosifier 1 1 0 J EMI-157 Control HTHP Fluid Loss 1 1 0 J CLEAN UP Detergent 2 1 0 J LIME Calcium source, alkalinity 2 0 0 E CALCIUM Control salt content of internal 1 0 1 E CHLORI DE (DRY) phase CALCIUM Brine, Internal phase 1 0 0 J CHLORIDE (BRINE) M-I BAR Weighting agent *1 0 0 E VG PLUS Organophic Clay viscosifier *1 0 0 E * HAZARDOUS MATERIALS IDENTIFICATION SYSTEM (HMIS) HAZARD RATINGS: 4 Severe hazard 3 Serious hazard 2 Moderate hazard 1 Slight hazard 0 Minimal hazard * An asterisk next to the health rating indi cates that a chronic hazard is associated with the material HMIS is a registered trademark of the Na- tional Paint and Coatings Association ** HMIS PERSONAL PROTECTIVE EQUIPMENT INDEX A - Safety Glasses B - Safety Glasses, Gloves C - Safety Glasses, Gloves, Synthetic Apron D - Face Shield, Gloves, Synthetic Apron E - Safety Glasses, Gloves, Dust Respirator F - Safety Glasses, Gloves, Synthetic Apron, Dust Respirator G - Safety Glasses, Gloves, Vapor Respirator.
