The well came on strong. The well then slowly increased in GOR till a CIBP was set in Dec -1993. This had little effect on the GOR. A subsequent plug was set in June -1994 which dropped the GOR, without damaging the oil rate. The well predictably slowly increased in GOR in Oct -2000. Multiple plugs were set/milled, etc. for the next year plus, till May - 2002 when the right combination was found restoring the wells production. The well has slowly increased to its current GOR. REASON FOR SIDETRACK: E -25 is not showing healing characteristics and has degraded to < 10 %. There are no further wellwork . options on this well. The proposed plan for E -25A is to drill a through tubing sidetrack with the SLB/Nordic 2 Coiled Tubing Drilling rig on or around April 15, 2013. The existing perforations will be isolated by the primary liner cement job. The sidetrack, E -25A, will exit the existing 5.5" liner, kick off and land in the Ivishak Zone 1A, then toe up in mid Ivishak Zone 1B. The following describes work planned and is submitted as an attachment to Form 10 -403. A schematic diagram of the proposed sidetrack is attached for reference. 4 ic 1i r w, 'C� !4 4 7 T R I- � 040 "snore, / P vl � �C f'�r� / A, .5 14.-r l/ l 0v la i ,4v/r6 /'GCXi i 0 j 114,'S cues" /' ��TicyC4a i" a'9 "' '1 0 fro/' 112;5 Pre -Rig Work: (scheduled to begin on March 10, 2013) 1.

Page l of 1 Subject: FW: INTENT PLUG for RE -DRILL WELLS: Corrected From: Davies, Stephen F (DOA) Sent: Monday, February 08, 2010 10:52 AM To: Foerster, Catherine P (DOA); McMains, Stephen E (DOA); Schwartz, Guy L (DOA); Saltmarsh, Arthur C (DOA); Aubert, Winton G (DOA) Subject: RE: INTENT PLUG for RE -DRILL WELLS: Corrected Revised procedure with an additional step per Cathy's comment: INTENT PLUG for RE -DRILL WELLS (IPBRD) Type Work Code in RBDMS 1. When a Form 10 -403 is submitted requesting approval to plug a well for redrill, the initial reviewer (Art or Steve D.) will check to make sure that the "Plug for Redrill" box in the upper left corner of the 403 form is checked. If the "Abandon" box is checked, we will cross that erroneous entry out and initial it on both copies of the Form 10 -403 (AOGCC's and operator's copies). 2. On the Form 10 -403 if "Abandon" is checked in Box 15 (Well Status after proposed work), Art or Steve D. will cross that erroneous entry out and initial it on both copies of the Form 10 -403 (AOGCC's and • operator's copies). Instead, we will check the "Suspended" box. Guy and Winton will serve as quality control for steps 1 and 2. 3. When Steve McMains receives the Form 10 -403 with a check in the "Plug for Redrill" box, he will enter the existing code "IBPRD" into RBDMS. This code automatically generates a comment under the History tab stating "Intent: Plug for Redrill." 4. When Steve McMains receives any Form 10 -407, he will check the History tab in RBDMS for this comment. If he sees the "Intent: Plug for Redrill" code, and cannot find any evidence that a subsequent re -drill has been COMPLETED, he will assign a status of SUSPENDED to the well bore in RBDMS, no matter what status is listed on the 10 -407. Steve will also change the status on the 10 -407 form to SUSPENDED, and will date and initial his change. If Steve does not see the "Intent: Plug for Redrill" comment or code, he will enter the status listed on the Form 10 -407 into RBDMS. 5. When the Form 10 -407 for the redrill is received, Steve M. will change the original well's status from suspended to abandoned. 6. The first week of every January and July, Steve M. and Steve D. will check the "Well by Type Work Outstanding" user query in RBDMS to ensure that all of the Plug for Redrill wells have been handled properly. At this same time, Steve M. and Steve D. will also review the list of suspended wells for accuracy.

Chatterton, Chairman 0il and Gas Conservation Commission State of Alaska 3001 Porcupine Drive Anchorage, AK. 99501 sR ENG SR ENG~~~I STANDARD ALASKA PRODUCTION A-A Dear Mr. Chatterton: Standard Alaska Production Company is requesting administrative approval, as outlined in Conservation Order No. 213, Rule 2, to waive productivity profile requirements for new high angle wells~and E-28. Both wells were drilled with "inverted" high angle wellbores (see Attachment). At present we are closely monitoring the production behavior of wells E-25 and E-28. While we believe it is possible to run a coiled tubing conveyed suite of production logs for these wellbore geometries, we do not believe at present that the value of the information obtained justifies the Costs and risks involved. While 1210 and 755 gross feet of perforations are open, only 94 and 93 vertical feet of the reservoir is exposed to E-25 and E-28 wellbores respectively. In the future, if production characteristics change sufficiently to warrant some kind of remedial work, it is likely that we would obtain these production logs. If you require further information to support these requests, please do not hesitate to contact J. T. Brown at (907) 564-4629. Very truly yours, T. N.

The permit to drill does 'not in4~mnify you from the probable need to obtain additional permits required by law from other ' governmental agencies prior to commencing operations at the well site. To aid us'in scheduling field work. please notify this office 24 hours prior to commencing installation of the blowout prevention equipment so that a representative of the Commission may be present to witness testing of the equipment before the surface casing shoe is drilled. Where a dtverter system is required, please also notify this office 24 hours prior to commencing equipment,installation so that the Commission may witness testing b~fo~e drilling below the shoe of the conductor pipe.
