History of E-20B: E-20B was completed as a CTD sidetrack in 2012. Unfortunately it came on with high GOR and has never been competitive and has no future wellwork options. The well has passed integrity and is fit for a sidetrack. Proposed plan for E-20C: Drill a through tubing sidetrack with the Nordic 1 Coiled Tubing Drilling rig on or around December 1St, 2015. The E 20C sidetrack will be a single string exit from the existing 3- 3/16" liner. A packer whipstock will be set with the rig allowing isolation from the parent perforations. The planned well kicks-off in Zone 4, builds through the conglomerates and will land and target reserves in Zones 1A/1 B. The proposed sidetrack is a -1150' horizontal Ivishak Zone 1 producer to be completed with a 2-3/8" L-80 solid liner, cemented in place and selectively perforated. This Sundry covers plugging the existing E-20B perforations via the packer whipstock set with the rig and liner cement lob or liner top packer, if the liner lap pressure test fails (alternate plug placement per 20 MC 25.112(i)). The following describes the work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the current well and proposed sidetrack is attached for reference.

Those wells that are not re-drilled immediately are identified every 6 months and assigned a current status of"Suspended." Step Task Responsible 1 The initial reviewer will check to ensure that the "Plug for Redrill" box Geologist S in the upper left corner of Form 10-403 is checked. If the "Abandon" or "Suspend"boxes are also checked, cross out that erroneous entry and initial it on both copies of the Form 10-403 (AOGCC's and operator's copies). 2 If the "Abandon" box is checked in Box 15 (Well Status after proposed Geologist Ais work) the initial reviewer will cross out that erroneous entry and initial then / it on both copies of the Form 10-403 (AOGCC's and operator's copies). �/ Instead, check the "Suspended" box and initial that change. Drilling Engineer The drilling engineers will serve as quality control for steps 1 and 2. (QC) 3 When the Stat Tech receives a Form 10-403 with a check in the "Plug Stat Tech for Redrill"box, they will enter the Typ_Work code "IPBRD" into the History tab for the well in RBDMS. This code automatically generates a comment in the well history that states "Intent: Plug for Redrill." 4 When the Stat Tech receives any Form 10-407, they will check the Stat Tech History tab in RBDMS for the "Intent: Plug for Redrill" code (IPBRD). If present and there is no evidence that a subsequent re-drill has been COMPLETED, the Stat Tech will assign a status of SUSPENDED to the well bore in RBDMS no matter what status is listed on the 10-407. The Stat Tech will also change the status on the 10-407 form to SUSPENDED, and date and initial this change. If the Stat Tech does not see the "Intent: Plug for Redrill" comment or code, they will enter the status listed on the Form 10-407 into RBDMS. 5 When the Form 10-407 for the redrill is received, the Stat Tech will Stat Tech change the original well's status from SUSPENDED to ABANDONED. 6 The first week of every January and July, the Stat Tech and one of the Stat Tech Geologists will check the "Well by Type Work Outstanding" user query Geologist in RBDMS to ensure that all of the Plug for Redrill wells have been handled properly. At this same time, they will also review the list of suspended wells for accuracy.

IN CASE OF A LEAK THE UPPER COMBIS'S MANUAL VALVE ON THE KOOMEY WOULD BE POSITIONED IN "NEUTRAL"TO ISOLATE THE LINE. FOLLOWING THAT,THE LOWER COMBIS WOULD BE CLOSED.

This is really only a change in liner tieback length and is and not part of the drilled section. A sundry to make this change is not required , I will place this email in our file as a record.

We originally had top of liner&cement at 9490'md &would like to change that to^'9090'md.This will slightly change our cement volumes by an extra 1.5bbls for a total of 15bbls.These changes will help in our future plans for this well.

Mud Program: • Milling/drilling: 8.6 ppg Power Pro for milling window and drilling (-631 psi overbalance). Disposal: • All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. • All Class I wastes will go to Pad 3 for disposal. Hole size: • 4.125" hole: 9,530' and - 10,771' and Casing Program: E-20B Production String Interval: • 3-1/2", L-80 9.2 lb/ft STL solid liner, 9,490' and - 9,520' and • 3-1/4", L-80 6.6 lb/ft TC-Il solid liner, 9,520' and - 10,771' and • The primary barrier for this operation: a minimum EMW of 8.4 ppg. • A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. ■ This liner will be cemented in place. o A minimum of 15bbls of 15.8 ppg Class G cement will be used for protection liner cementing. (Assuming 4-1/8" hole size as specified above with 40% excess in open hole & 170' of 4-1/2" liner sump to CIBP at 9,700' md). o TOC planned at 9,490' md. Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3,500 psi. • The annular preventer will be tested to 250 psi and 3,500 psi. Directional • See attached directional plan. Maximum planned hole angle is 84.97°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property - 7,600'. • Distance to nearest well within pool - 1650'. Logging • MWD directional, Gamma Ray and Resistivity will be run over all of the open hole section. • Cased hole GR/CCL logs will be run. Anti-Collision Failures: • None. Hazards • The maximum recorded H2S level on E pad was 110 ppm on well E-102 on 5/11/2011. • Lost circulation risk is considered high due to the location of the well path in the Midfield Graben. Reservoir Pressure • The reservoir pressure on E-20B is expected to be 3,304 psi at 8,800' TVDSS. (7.2 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,424 psi. • An EMW of 8.4 ppg for this well will provide 539 psi over-balance to the reservoir. 1.1;1, Matthew Ross bD CC: Well File CTD Engineer Sondra Stewman/Joe Lastufka TREE= 4-1/16"CIW _ WELLHEAD= FMC E_2 0 A 4-1/2"CFFUAET ACTUATOR= OTIS KB.ELEV= 60.54' BF.ELEV= 32.01' L I ' ' KOP= 3000' —LL� Max Angle= 37 @ 4100' 34' —I5-1/2"X 4-1/2"XO,ID=3.958" _Datum MD= 9800' I I 2112' —14-1/2"HES X NIP,ID=3.813" Datum TVD= 8800'SS 13-3/8"CSG,72#, L-80,ID=12.347" —I 2699' {--, , GAS LIFT MANDRELS ST MD TVD DEV TYPE VLV LATCH PORT DATE 4 3430 3416 19 KBG2 DMY BK 0 08/12/11 L. 3 6181 5705 34 KBG2 DMY BK 0 04/30/05 2 7967 7214 29 KBG2 DMY BK 0 10/16/04 Minimum ID = 3.725" @ 9261' 1; I� 1 9085 8185 26 KBG2 DMY BK 0 10/16/04 4-1/2" HES XN NIPPLE 1i ►. 11 ►. —4400' —I EST.TOP OF CEMENT 14 �1 t' ,' 8607' H 7"HES FLOAT COLLAR w/3/8"ORIFACE HOLE 1 ► 8624' —17"BKR LOC&SEAL ASSY(3 SETS),ID=6.17" I 7"TIEBACK/SCAB LNR 26#,L-80 8625' I 8625' I9-5/8"X 7"BKR ZXP LNR TOP PKR BTC-M,.0383 bpf,ID=6.276" 1w/TIEBACK SLV,ID=6.30" 8642' —19-5/8"X 7"BKR HMC LNR HGNR,ID=6.310" MILLOUT WINDOW(E-20A) 8767'-8783' TOP OF WHIPSTOCK(10/02/04) —I 8767' 9-5/8"EZSV(10/01/04) -j 8810' 69195' —14-1/2"HES X NIP, ID=3.813" 9216' I—7"X 4-1/2"BKR S-3 PKR,ID=3.875" 9240' —14-1/2"HES X NIP,ID=3.813" TBG STUB(09/30/04) --I 8870' O�1.14 SAL 9240' —4-1/2"XX PLUG(08/12/11) [IOW 111.. _ " '� 9261' —14-1/2"HES XN NIP,ID=3.725" 5-1/2"TBG, 17#,L-80,ID=4.892" --I 8909' ��'���������, �� .1r 9266' 7"X 5"BKR ZKP LNR TOP PKR 1111) 1 w/TIEBACK SLV,ID=4.44" TOP OF 7"LNR 8959' 1 x.111.1 r�����i 9273' —4-1/2"WLEG,ID=3.958" I 4-1/2"TBG, 12.6#,L-80,ID=3.958" --I 9051' 1' `•> -4,:,...1. 9-5/8"CSG,47#,L-80, ID=8.681" — 9458' 400.0 \ 9279' 7"X 5"BKR FLEX- O . 1.6.6.6.6.6.6.6.1 Pr.
