The tool was run in the up-flow configuration with the annulus open and returning approximately 940 bpd tO the surface. The up-flow survey was then repeated with the annulus closed. The tool was then changed to the down-flow configuration and a down-flow survey was completed, This report presents the most likely interpretation which could be derived from the measured data. Because of the complicated nature of the tubular configuration In this well other possible flow paths may exist which could lead to the observed results. Summary of Findings: The Short String Sliding Sleeve at 10215 is leaking. There is a small leak at or just above the Dual Packer at 10249. A T~!bin9 leak ex, ists.b,etween 2500 a,,n, d 30.00 feet .... The 9 5/8" casing has a leak(s) between 3000 and 5000 feet. Down flow is occurring outside the 13 3/8" easing from 500 to 1000+ feet. ii .......... i .__ WFL Discussion: . With the tubing x 9 5/8'.annulus open during Injection the well was returning -940 bpd to the surface. This flow originates in small part at or just above the Dual Packer at 10249 and mainly from the SS sliding sleeve at 10215 feet. With the tubing x 9 5/8" annulus closed this flow continues at a reduced rate up to between 5000 and 3000 feet where it exits through a.hole or holes in the 9 5/8" casing. Annular down:flow is seen beginning between 2500 and 3000 feet indicating at least one of the tubing strings is leaking in this interval. This flow Is believed to exit the 9 5/8" cssing through a hole or holes between 3000 and 5000 feet. This flow continues down the 9 5/8" x 13 3/8"/OH annulus to below 10245 ff where it exits into the formation. The effect of this exit Is seen on the shut-in temperature log. The shut-in temperature Icg aisc confirms a down flow to be occurring outside the 13 3/8" casing from above 500 feet to below 1000 feet where it exits into the formation.

Our goal was to prove no holes in the casing and request a variance, which would have saved us over $8MM in repairs. Unfortunately, all the WFL's suggested holes in the casing. Even though only one of the temperature surveys showed a hole in the casing (which didn't correlate with a hole suggested by the WFL), we were so confident that the WFL's were correct we decided to bit the bullet and work the wells over and repair the casing holes. When we went to do the work there was good news and bad news. The good news was there was only one hole in any of the casings (the one the temp survey clearly showed - G-36DPN) and we were able to save over $3MM in repair costs. The bad news was we still spent over $4MM in workover costs which may have been unnecessary if we were able to obtain variances on them. I have attached three examples: G-36DPN G-22 G-16 WFL showed multiple leaks between 3000 and 5000 MD. Temp survey showed leak between 10,200 and 10,300 MD. Pressure testing confirmed leak identified by Temp survey and proved leak identified by WFL to be nonexistent. WFL showed multiple leaks between 4750 and 6000 MD. Temp survey showed possible leak between 8,900 and 9,400 MD. Pressure testing proved no leaks exist. WFL showed leak between 6300 and 6500 ft. Temp survey had minor temp variations over the length of the log but was interpreted as noise. Pressure testing proved no leaks exist. If I can be of further assistance please don't hesitate to call me at 263-7830 or Steve Tyler at 263-7649. Sincerely, Reasons for no WFL's on Baker. doc Christopher A.

With the annulus closed a reduced llow rate of about 100 bpd Is indicated moving up from below 12110 feet.

No further up flow was seen above this point with the annulus closed. Down-flow measurements Indicate a hole in the tubing between 3500 and 4000 feet where flow ia measured in the tubing x 7" annulus, This flow appear9 to continue down to -6400 feet where it merges with the up-flow, exits the 7" casing and flows down the 7"x 9 5/8" annulus.

A rate of 256 bpd is shown to be leaking past the dual packer at 10249 feet. This rate increases at the station at 10205 feet indl(;ating a significant leak In the short string sliding sleeve at 10215 feet. An additional small leak was indicated in the long string sliding sleeve at 10178 allhough this Increase ie near the resolution of the WFL measurements. With the tubing to 9 5/8" annulus ~losed no flow was seen leaking up past the dual packer at 10249 however at rate of about 200 bpd appears to ofigtnate at the LS sliding sleeve at 10178. This up-flow continues up Ihs tubing x g 5/8" annulus until between 6000 to 3000 feet where It exits the 9 5/8" casing. An additional up-flow was measured at 10500 ff which may be flowing up the 7" x 9 5/8" annulus. Down-flew possibly in the tubing x 9 5/8" annulus la seen at 500 and 2.000 feet. This flow appears to exit the g 6/8" casing between 1000 and 2500 feet and continues down outside the 9 5/8" casing past the lowest WFL elation at 10550 feet..

Below is a brief discussion: With the tubing to g 5/8" annulus open during injection the well was returning 1043 bbls to the surface. This flow appears to be coming in small part from the L$ sliding sleeve at 9082 and mainly from the SS sliding sleeve at 9051. No flow Is seen coming up past the packer at 9119 feet. ,. With the tubing to 9 5/8" annulus closed no up-flow was seen in the welt, Instead down-flow begins between 2400 and 2500 feet Indicating at least one of the tubing strtngs is leaking in this interval, Increases in the down-flow rate between 2400 and 2650 Indicate the possibility of multiple leaks, This flow continues down the tubing x 9 5/8" annulus to around 4000 ft wllere changes in velocity Indicate it possibly exits into the g 5/8" x 13 3/8" annulus and continues down. Between 61500 and 7000 feet the down-flow stops indicating lhe flow has exited into the formation, I hope to have the G-40 and G-36DPN interpretations out shortly.

The WFL Down Flow rates were calculated for the 9 5/8" x 13 3/8" annular area .. from surface to the boltom of the 13 3/8" at 5548'. Below Ihls point the area was assumed to be the full g 5/8" x 12.25" OH annulus. Increase or decreases In this annular area would have a corresponding effect on the calculated flow rates, The data Indicates Down Flow starting between 1800' and 2000' and continuing down beyond the lagt station at 9500'. The possibility exists that the Indicated Down Flow may be in the tubing x 9 5/8" annulus from 2000' to 4750' at which point it converges with the Up Flow and exits the 9 5/8" through the same point and continues down outside the 9 6/8'. The tubing spinner surveys both show an unexplained drop in Injection rata below -1000' which may best be explained by a ID reduction above this point (scale?), The Long String survey shows an additional slight drop Just below 1500' which could account for Ihs start of the WFL Down Flow Indication mentioned above.

The spinner data appears to be verified by' the temperature data whlch shows cooler temperatures in the Short String which would be expected at a htgher Injection rate.

This flow appears to originate from the sliding sleeves at 9762 and 9760 In the long anu short strings. No flow is seen coming up past the packer al g789 feet. With the tubing to 9 5/8" annulus closed up-flow continues at a reduced rate. This flow travels up the tubing x 9 §/8" annulus until between 3350 and 3250 ft where It exits the 9 5/8" casing, An additional up-flow la measured across the lower packer at 10378. Down-flow In the tubing x 9 5/8" casing is seen starting between 900 and 1200 feet. This flow continues down and appeam to exit the 9 5/8" casing in the same Interval as the up flow mentioned above (--3300 fl). This combined flow then travels down the g 5/8" x 13 3/8"/OH annulus to the reservoir at or below 10000 lest. Workin[j on G-36DPN now. SCANNED DEC 1 ~ 2002 Regards, Rob...

I. Supervisor g/¢_rl,,~ FROM' Lou Grimaldi~ Petroleum Inspector FILE NO: SUBJECT: AU9JDSFE.DOC BOP Test, Grayling UNOCAL G-36RD McArthur River Field PTD #87-0049 Sunday, April 19, 1998; I witnessed the weekly BOP test on the Grayling rig #54 working over UNOCAL well #G-36RD in the McArthur River Field. I arrived to find the rig almost ready to test. I witnessed three Mechanical Integrity tests (see JU9JDSFE.DOC) while I waited for the rig to finish tripping out and set the test plug. The test, once started went very well and I was impressed with the procedure used. All BOPE components were tested with no failures observed. The gas detectors were tested and initially there was a problem with the H2S detectors but it was found to be bad sample gas. A new bottle was obtained and the detectors functioned properly. It should be noted that this rig has worked over three water injectors and done much fishing, these two circumstances are hard on equipment and usually a failure or two is to be expected. This was not the case today and as noted above all equipment worked properly. SUMMARY: The weekly BOPE test I witnessed on UNOCAL's Grayling rig #54 revealed the following; Test time 4 hours, No Failures. Attachments: AU9JDSFE.XLS CC; Dan Williamson (Unocal Drilling Supt.)

The well is currently a shut-in water injector with a dual completion in the G-zone and the West Forelands. The well is shut-in due to tubing leaks in both strings of tubing and a leaking dual packer. The proposed workover will remove the dual tubing and dual packer. The long string tubing will be removed above a lower single packer which will allow perforations in the Hemlock Benches 1, 3 and 4 to be added after the rig workover. A new single packer and single 3-1/2" injection tubing will be run above the present G-zone completion. During the workover, a test packer will be run to evaluate the integrity of the 9-5/8" casing. Workover Procedure: 1. Check tubing for pressure. Ensure annulus is full of liquid. 2. Install back pressure valve. ND tree. 3. NU BOPE, pull BPV and install 2-way check. Test BOPE with 24 hr notice given to AOGCC for ' witness. 4. Pull 2-way check valve. Engage short string tubing hanger with landing joint. 5. Pull tubing 10' and monitor well, circulate FIW down tubing and up annulus (1-1/2 well volumes) to ensure well is clear of gas. 6. I~OOH laying down short string tubing. 7. Pull long string tubing and dual RDH retrievable packer. (Long string is parted below dual packer at 11,329') 8. RIH with 9-5/8" test packer and set packer just above 7" liner top at 10,354'. Pressure test 9-5/8" casing to 2010 psi. 9. Fish remainder of long string tubing down to suspected parted tubing above lower packer at 12,507'. 10. Run completion with hydraulic set permanent injection packer and 3-1/2" tubing. I 11. Set packer at ~D/8037' TVD. Pressure test annulus to 2010 psi. (.25 x TVD of packer) 12. Set BPV and ND BOPE. NU tree and retest annulus to 2010 psi with AOGOO witness for injection well MIT. 13. Release rig. Start water injection. AOGCCprocG36.DOQ UNOCAL ) Grayling Well ~J6RD Rig Workover AFE #130341 14.

A rate of 256 bpd is shown to be leaking past the dual packer at 10249 feet, This rate increases at the station at 10205 feet indicating significant leak In the short string sliding sleeve at 10215 feet. An additional small leak was indicated in the long string sliding sleeve at 10178 although this increase ie near the resolution of the WFL measurements. With the tubing to 9 5/8" annulus closed no flow was seen leaking up past the dual packer at 10249 however at rate of about 200 bpd appears to originate at lhe LS sliding sleeve a! 10178, This up-flow continues up the tubing x 9 5/8" annulus until between 5000 to 3000 feet where It exlta the 9 5/8" casing. An additional up-flow was measured at 10500 ff which may be flowing up the 7" x 9 5/8" annulus. Down-flow possibly in the tubing x 9 5/8" annulus is seen at 500 and 2000 feet. This flow appears to exit the 9 6/8" casing between 1000 and 2500 feet and continues down outside the 9 5/8" casing past the lowest WFL station at 10550 feet,.

Dear Blair: Water-flow logs were run on G-36DPN and G-40 on January 25 and January 23, respectively. The initial results from these logs indicated that there are leaks in thc %5/8" casing suings. Each well was shut-in following the analysis of the logs. Copies of the WFL interpretations will be sent this Friday for these wells and G-5. Attached is a copy of the G-22 WFL interpretation by Rob North of C~osource. These wells are preliminarily scheduled to be repaired for late 1998 aad early 1999.
