Supervisor FROM' Chuck Scheve; SUBJECT' Petroleum Inspector DATE: April 20, 2001 Safety Valve Tests Prudhoe Bay Unit K Pad~ Friday, April 20~ 2001: I traveled to BPXs K Pad and witnessed the 30-day retest of the safety valve systems. As the attached AOGC'C Safety Valve System Test Report indicates I witnessed the testing of 11 wells and 22 components with 3 failures. The pilots on wells K-06, K- 07 and K-09 tripped below the required set point. The pilot on well K-09 was retested and operated properly. Wells K-06 and K-07 normally flow into the Iow- pressure system (at 200 to 300 psi) but were recently switched into the'high- pressure system. The pilots on these two wells were left in the iow ~pressure setting (125 psi) and tdpped near this set point but were failed on this test due to the :higher flowing tubing pressure required to produce into the high pressure system. These two pilots were adjusted to the higher set pressure (550 psi) and retested at,this time. Merv Liddelow performed the testing today; he demonstrated good test procedures and was a pleasure to work with. A walk through inspection of the well houses on this pad was performed during the SVS testing with no problems noted. All well houses inspected were reasonably clean and all equipment appeared to be in fair conditions. Summary: ! witnessed the 30-day retest of the safety valve systems at BPXs K- _ Pad in the Prudhoe Bay Field.

Diverter, BOPE and drilling fluid system schematics on file with AOGCC. NO ANNULAR INJECTION IN THIS WELL. K~16A Class II drilling wastes will be disposed at CC-2A grind and inject facility. If Class I wastes are generated, they will be taken to Pad 3 disposal site. Bottom hole pressure in the target sand is 3,500 psi at 8,800' TVDss (estimated) or 7.2 EMW. The overbalance with 8.9 QuickdrilN is 572 psi, or 1.25 PPG. This is the highest bottom hole pressure expected in the wellbore trajectory. Maximum shut-in casing pressure is 2,620 psi (assumes 0.1 psi/ft gas gradient to surface). Drilling Discussion Well Objective The Pad K development seeks to exploit the target Gravity Drainage in the base of Zone 1 with well K- 16A and to leave the well set up for additional sidetracks into the surrounding area. The trajectory of the well is to expose as many basal mouth bar deposits, allowing gravity drainage from fluvial and distributory channels above. The objective of the well is to drill an essentially horizontal section through Zone 1 basal 13P sand'and follow the structure, optimizing standoff from gas, and Kavik. This well path optimizes exposure to the base of Zone 1 above the Kavik, standoff from GOC and faults for good cement zonal isolation. The cement program has been extensively modified to successfully run 2 RH turbulators/jt, eliminate the inner string & improve liner flexibility. Additionally, the program developed with the Asset, the Fluids Company, The Rig Team, Baker, B J, and Halliburton allowed partial reciprocation in K-06A and full reciprocation while cementing in K-20A. Excess cement was circulated out the long way to eliminate liner top/tool release problems. The well path of K-06A crossed 3 major faults without losses, K-16A has the potential for small faults which also present some potential, though thought to be minimal. Drilling Objective The objective is to chemically cut and pull the existing 4 V2" completion tubing at 9470 MD. The 6" whipstock sidetrack will exit the 7" casing at this point, into the TSAD @8309 TVDss, landing into the base of Z1 @8690 TVDss (10,016'MD), with TD of the 6" hole section in the base of Zone 1 at 8695 TVDss and 12,107 MD. Directionally drill with first Build&Turn Tri-Cone Assy BHA equipped with MWD/GR/Dir from 9470 MD to 10,016' MD. The Second Lateral BHA will add Res and will build to 90 degrees @ TI (Poly 1) @ 10,015 MD, and TD @ 12,107'MD @ 88 degrees. A CTU~memory CNL will be run after the rig moves off the well and prior to putting the well on production to determine the GOC. The target risk is low and confined mainly to structurally small faults and uncertainty of exact GOC. A high quality cement job, obtainable with a modified conventional 2 RH turbolators/jt, cementing program developed on K-06A/K-20A and continued here on K-19A, has obtained good isolation. Better standoff/centralization with engineered displacements & sweeps, with in-guage wellbore improve bonding, minimize channels which cause premature coning, and the use of clean & non- damaging perforating pills eliminates damage during perforation and subsequent protection from seawater/brines containing corrosion inhibitors. Eliminating the inner string increases flexibility of liner w/2 turb/jt, and has shown promise of eliminating cleanout runs, and improving perf gun placement. The K-19A well will be completed as a Zone 1 producer with a 4 ½", L-80, 12.6//liner, (4) GLM's and WOA tailpipe assy. The GLM's will be run at the MDs to be determined by the Asset/Pad Engineer. DRILLING HAZARDS AND CONTINGENCIES Always have two levels of tested isolation before NU/ND. SURFACE CLOSE APPROACH WELL SHUT-INS There are 2 wells, K-03 & K-13, within 40' which will need to be shut in during MIRU and RDMO. This will be identified via Shut In Memo, Pre-Rig, and the final approved Well Plan. DRILLING CLOSE APPROACH WELL SHUT-INS No downhole shut-ins identified on Sperry Sun directional well plans or by Asset due to close approach requirements. HOLE PROBLEMS This well will cross small known faults, with a small predicted possibility for lost circulation, or gas cut mud and gas kicks after crossing any of the faults. The faults are not prognosed to be problematic, however, their depths were identified earlier, and normal precautionary measures will be taken. Lost circulation, if it occurs, will be handled using a comprehensive lost circulation decision tree. All rig personnel should be aware and ready to effectively react to any gas kick potential. Ready to shut in any kicks and weight-up and safely circulate-out the kick. Differential sticking is a possibility while drilling across any of the faults. However, fluid design is such that differential sticking has not been a problem, even when drilling and completing with >2000 psi overbalance. Casing Shoe Kick Tolerance The smallest kick tolerance for the kick off window is calculated as infinite of influx assuming a swabbed gas influx at the top of the Sag River along the planned directional path. Based on 8.7 ppg MW (SAD 13P 8,800' TVD 7.2 ppg reservoir pore pressure), and min. frac at the window 10.0 ppg. The casing window will withstand complete (gas) evacuation to surface based on predicted pressures. Pre-Rig / Pre-Drill Work 1. RU wireline and retrieve the 4.5" SSSV. Valve nipple is set at 2103'MD. Test 9-5/8" packoff and tubing hanger packoff to 5000 psi and carefully cycle LDS. 2. Circulate Seawater as needed to prepare well for perforation & Slotted Liner squeeze abandonment. 3. Perf interval above slotted liner is inside the 7" liner. 4. P&A slotted liner, and perfs, with cement top > 100 above perfs. Lay in cement with CTU, WOC, cleanout and test for 30 minutes at 3000 psi. 5. Cut the 4.5" tbg in the middle of a full joint of tubing at .--9495'MD for setting whipstock. 6. Test 7" to 3000 psi before cut or retest both IA and tubing after cut. 7. If a chemical cut, follow recommended practices for successful chemical cuts, including double anchors, and balanced IA/tubing hydrostatic. 8. Displace the tubing and wellbore to 8.5 ppg seawater 9. Freeze protect top 2200'MD with diesel. 10. Bleed tubing and annuli pressures to zero. 11. Set a BPV in the tubing hanger and test from below to 1000 psi. Secure the well 12. Remove the well house and flowlines. If necessary, level the pad. K-03 & K-13 are within 40' of the K-16 wellhead. Ensure that well is shut-in during MIRU and during RDMO operations with as little shut-in time as possible. Please provide total well preparation cost on the handover form. Rig Sidetrack Procedure o 3. MIRU. Coordinate with Pad Engineer prior to MIRU D-16 that surface close approach wells are shut in. Minimize shut in times during MIRU and RDMO with Pad Engineer. Obtain PE handover notes, completed, confirming well status before completing handover. Test packoffs to 5000 psi if not confirmed in pre-rig work.. Bleed off pressures to zero. Pull BPV. Circulate out freeze protection (if required) and circulate well with seawater. Install TWCV and test to 1000 psi. ND tree and send to DSM for refurbishing. NU BOP and notify AOGCC to witness or obtain waiver. Perform a full BOP test- 250/5000, annular 250/3500. Pull TWCV. 4. Pull the 3 V2" tubing completion from cut at 9470'. Call DSM for Norm readings if scale is present. Inspect quality of cut and report to SLB for database. o Viscosify seawater or used Quickdril to > to beginning milling ops. -80K LSRV, & >20 initial gels w/XC polymer prior o PU Baker Bottom Set WindowMaster One-Trip Mill and RIH to Set and orient on tubing stub @ *-9495 MD'.

Inspect mill for confirmation of window integrity. Use ditch magnets and keep them clean. Monitor metal and scale returns. Clean pits and take on new 80K LSRV 6 % KCL / 5 % Lubetex drill-in fluid. The fluid will shear down rapidly on first circulations, and sending out above 80K will ensure that the fluid is easier to maintain at the start. ~ o PU STR-20DX 6" insert bit and Sperry BHA#1 (See BHA Attachment) Sidetrack/Build/Turn assembly with MWD/Dir/GR/tools and kick-off directionally drilling 6" hole from TSAG to BHA#1 landing pt @ 10,016'MD (8620 TVDss) in Zone lB.. 8. PU BHA #2 Lateral PDC Assembly with 6" insert bit with MWD/Dir/GR/Res tools. Continue with this assembly to lateral TD at 12,107'MD (8695'TVDss). 9. Optimize gas standoff and Kavik basal standoff, while crossing a series of small faults. Prepare for losses associated with faults, though not expected as highly probable or likely. 10. Keep Fluid specs maintained at all times for optimum performance. Keep solids low and change out fluid if sliding becomes difficult. If there are any ROP/sliding problems, call to discuss. Keep active Lubetex concentration at 5 % and utilize Lubetex spotting pills (and beads if necessary) if drilling hard, or sticky formation. 11. At TD circulate and condition the wellbore as in K-06A/K-20A/K-19A "Conventional Production Cementing Pump Down Job, Modified Procedure" for optimum wellbore conditions for running and cementing liner, conventionally, with 2 RH turbulators/jt to just above GOC. 12. We will be repeating all steps (though some will be deleted as K-06A/K-20A/K-19A results confirm) except where the attached document has been modified. Run tandem scraper/bit run to top of float shoe based on results of prior 2 wells. This will be test number 4, unless the Asset Engineer decides to drop this on this well. One objective of this cement technique is to eliminate this cleanout run. 13. Run and cement 4.5" liner with the'modified conventional program from K-06A/K-20A/K- 19A (attached). Displace cement with 150,000 cps/5% Lubetex/6% KC1 perf pill -- to liner volume plus 30 bbls excess pill for cement pusher pill. Displace pills with circulating Quickdril-N. Reference procedure for rig floor cement manifold setup to divert cement wash water to slop tank, avoiding cement shoe contamination or contamination to perf pill, and minimizing shut down to a few minutes. After plug bumps, and liner hanger and liner top packer are set, keep 1000 psi on drillpipe/liner. When you rotate 6 turns to the right and release from setting tool, the 1000 psi and the 30 bbl 150,000 LSRV/5% Lubetex, lead fluid, will act as a pusher pill to start moving the excess cement up the annulus. Pump at max rate set back down on liner top with slack weight of 40K to confirm liner top packer set, while circulating at max rate (with C-2 running tool only) Test liner lap to 3000 psi. Follow recommended practice for liner top 150' inside 7". While circulating out the excess cement, stay on pit fluid until you get clean returns and then circulate to clean seawater. 14. 150,000 cps 5% clarified Xanthan 6% KC1 perf pill inside liner is to prevent sticking perf guns during 100 psi underbalanced perforation on K-19A and to minimize formation damage, especially from fluid loss of inhibitor-treated brines, and to avoid sticking guns in influx of perf debris. POOH ' for perf guns. Run DPC Halliburton 2-3/4" RDX DP (12.5 gm), 4 spf, random orientation, 60 degree phasing perforating guns with Champ Perf packer. Perforate 100 psi underbalance. (Perforating memo will be distributed after logs, identifying intervals and procedures.) POOH & lay down guns. 15. Complete well with 4 1/2", L-80 tubing, Baker 4.5x7" S-3 packer set at 9320 MD (150' inside of window of 7" at 9470'. Completion string will include (4) GLM's and WOA tailpipe assembly, WLEG spaced & stung into top of liner tieback sleeve, and modified X nipple profile instead of SSSV. (Note: Have Camco pin the RP for 2400 psi nominal instead of 2900 and paint with white stripes to denote change. When testing tubing to 3500, only bleed tubing to 2000 psi prior to testing IA to 3000 to leave a 1000 psi differential across RP and prevent shear. Carefully bleed off IA & tubing pressures to avoid shearing RP. Contact ODE and Camco for details when you get to this step or reference attached document (also in rig files). This is our fifth well on which we have utilized this modified procedure with solid success. Space WLEG to place inside of 4.5" liner tieback sleeve when tubing is landed. Pull up and reverse circulate filtered seawater with Corexit @ 25 gal/100 bbls. 16. Position WLEG inside 4.5" tieback sleeve, land tubing and drop packer setting ball. Set the packer and test the tubing to 3500 psi for 30 min. Only bleed to 2000 psi. Test annulus to 3000 for 30 min. Slowly bleed tubing and record pressure differential when RP shears. Do not freeze protect yet. 17. Install TWCV in the tubing hanger and test from the annulus to 1000 psi. 18. Nipple down BOP equipment. 19. NU and test tree to 5000 psi. (Notify AOGCC in advance to witness or waiver) Pull TWCV. 20. Displace the annulus with diesel to 2000', overdisplacing sufficient volume through top GLM to freeze protect tubing to 2000', chasing with seawater. Install BPV, test from below, and secure the tree. 21. RDMO, pick up matting boards and herculite, clean area, perform a post rig site inspection with Pad Operator, and handover/release rig to Production. 22. Notify PE' s that tie-in will require dual P-Pilot to complete and put well on production. Minimize shut-in time of K- 1'7 A. 8I 11· 9· 6· · 1 ·12 · 2^ ·14 · 4 K PAD~''~ VICINITY MAP N.T.S.

If Class I wastes are generated, they will be taken to Pad 3 disposal site. Bottom hole pressure in the target sand is 3,500 psi at 8,800' TVDss (estimated) or 7.2 EMW. The overbalance with 8.9 QuickdrilN is 572 psi, or 1.25 PPG. This is the highest bottom hole pressure expected in the wellbore trajectory. Maximum shut-in casing pressure is 2,620 psi (assumes 0.1 psi/ft gas gradient to surface). Drilling Discussion Well Objective The Pad K development seeks to exploit the target Gravity Drainage in the base of Zone 1 with well K- 16A and to leave the well set up for additional sidetracks into the surrounding area. The trajectory of the well is to expose as many basal mouth bar deposits, allowing gravity drainage from fluvial and distributory channels above. The objective of the well is to drill an essentially horizontal section through Zone 1 basal 13P sand and follow the structure, optimizing standoff from gas, and Kavik. This well path optimizes exposure to the base of Zone 1 above the Kavik, standoff from GOC and faults for good cement zonal isolation. The cement program has been extensively modified to successfully run 2 RH turbulators/jt, eliminate the inner string & improve liner flexibility. Additionally, the program developed with the Asset, the Fluids Company, The Rig Team, Baker, BJ, and Halliburton allowed partial reciprocation in K-06A and full reciprocation while cementing in K-20A. Excess cement was circulated out the long way to eliminate liner top/tool release problems. The well path of K-06A crossed 3 major faults without losses, K-16A has the potential for small faults which also present some potential, though thought to be minimal. Drilling Obiecfive The objective is to chemically cut and pull the existing 4 1/2" completion tubing at 9470 MD. The 6" whipstock sidetrack will exit the 7" casing at this point, into the TSAD @8309 TVDss, landing into the base of Z1 @8690 TVDss (10,016'MD), with TD of the 6" hole section in the base of Zone 1 at 8695 TVDss and 12,107 MD. Directionally drill with first Build&Turn Tri-Cone Assy BHA equipped with MWD/GR/DIr from 9470 MD to 10,016' MD. The Second Lateral BHA will add Res and will build to 90 degrees @ T1 (Poly 1) @ 10,015 MD, and TD @ 12,107'MD @ 88 degrees. A CTU memory CNL will be run after the rig moves off the well and prior to putting the well on production to determine the GOC. The target risk is low and confined mainly to structurally small faults and uncertainty of exact GOC. A high quality cement job, obtainable with a modified conventional 2 RH turbolators/jt, cementing program developed on K-06A/K-20A and continued here on K-19A, has obtained good isolation. Better standoff/centralization with engineered displacements & sweeps, with in-guage wellbore improve bonding, minimize channels which cause premature coning, and the use of clean & non- damaging perforating pills eliminates damage during perforation and subsequent protection from seawater/brines containing corrosion inhibitors. Eliminating the inner string increases flexibility of liner w/2 turb/jt, and has shown promise of eliminating cleanout runs, and improving perf gun placement. The K-19A well will be completed as a Zone 1 producer with a 4 ¥2", L-80, 12.64/liner, (4) GLM's and WOA tailpipe assy. The GLM's will be run at the MDs to be determined by the Asset/Pad Engineer. DRILLING HAZARDS AND CONTINGENCIES Always have two levels of tested isolation before NU/ND. SURFACE CLOSE APPROACH WELL SHUT-INS There are 2 wells, K-03 & K-13, within 40' which will need to be shut in during MIRU and RDMO. This will be identified via Shut In Memo, Pre-Rig, and the final approved Well Plan. DRILLING CLOSE APPROACH WELL SHUT-INS No downhole shut-ins identified on Sperry Sun directional well plans or by Asset due to close approach requirements. HOLE PROBLEMS This well will cross small known faults, with a small predicted possibility for lost circulation, or gas cut mud and gas kicks after crossing any of the faults. The faults are not prognosed to be problematic, however, their depths were identified earlier, and normal precautionary measures will be taken. Lost circulation, if it occurs, will be handled using a comprehensive lost circulation decision tree. All rig personnel should be aware and ready to effectively react to any gas kick potential. Ready to shut in any kicks and weight-up and safely circulate-out the kick. Differential sticking is a possibility while drilling across any of the faults. However, fluid design is such that differential sticking has not been a problem, even when drilling and completing with >2000 psi overbalance. Casing Shoe Kick Tolerance The smallest kick tolerance for the kick off window is calculated as infinite of influx assuming a swabbed gas influx at the top of the Sag River along the planned directional path. Based on 8.7 ppg MW (SAD 13P 8,800' TVD 7.2 ppg reservoir pore pressure), and min. frac at the window 10.0 ppg. The casing window will withstand complete (gas) evacuation to surface based on predicted pressures. Pre-Rig / Pre-Drill Work 1. RU wireline and retrieve the 4.5" SSSV. Valve nipple is set at 2103'MD. Test 9-5/8" packoff and tubing hanger packoff to 5000 psi and carefully cycle LDS. 2. Circulate Seawater as needed to prepare well for perforation & Slotted Liner squeeze abandonment. 3. Perf interval above slotted liner is inside the 7" liner. 4. P&A slotted liner, and perfs, with cement top > 100 above perfs. Lay in cement with CTU, WOC, cleanout and test for 30 minutes at 3000 psi. 5. Cut the 4.5" tbg in the middle of a full joint of tubing at -9495'MD for setting whipstock. 6. Test 7" to 3000 psi before cut or retest both IA and tubing after cut. 7. If a chemical cut, follow recommended practices for successful chemical cuts, including double anchors, and balanced IA/tubing hydrostatic. 8. Displace the tubing and wellbore to 8.5 ppg seawater 9. Freeze protect top 2200'MD with diesel. 10. Bleed tubing and almuli pressures to zero. 11. Set a BPV in the tubing hanger and test from below to 1000 psi. Secure the well 12. Remove the well house and flowlines. If necessary, level the pad. K-03 & K-13 are within 40' of the K-16 wellhead. Ensure that well is shut-in during MIRU and during RDMO operations with as little shut-in time as possible. Please provide total well preparation cost on the handover form. Rig Sidetrack Procedure . . . MIRU. Coordinate with Pad Engineer prior to MIRU D-16 that surface close approach wells are shut in. Minimize shut in times during MIRU and RDMO with Pad Engineer. Obtain PE handover notes, completed, confirming well status before completing handover. Test packoffs to 5000 psi if not confirmed in pre-rig work.. Bleed off pressures to zero. Pull BPV. Circulate out freeze protection (if required) and circulate well with seawater. Install TWCV and test to 1000 psi. ND tree and send to DSM for refurbishing. NU BOP and notify AOGCC to witness or obtain waiver. Perform a full BOP test- 250/5000, annular 250/3500. Pull TWCV. . Pull the 3 V2" tubing completion from cut at 9470'.

PU BHA #2 Lateral PDC Assembly with 6" insert bit with MWD/Dir/GR/Res tools. Continue with this assembly to lateral TD at 12,107'MD (8695'TVDss). 9. Optimize gas standoff and Kavik basal standoff, while crossing a series of small faults. Prepare for losses associated with faults, though not expected as highly probable or likely. 10. Keep Fluid specs maintained at all times for optimum performance. Keep solids low and change out fluid if sliding becomes difficult. If there are any ROP/sliding problems, call to discuss. Keep active Lubetex concentration at 5 % and utilize Lubetex spotting pills (and beads if necessary) if drilling hard, or sticky formation. 11. At TD circulate and condition the wellbore as in K-06A/K-20A/K-19A "Conventional Production Cementing Pump Down Job, Modified Procedure" for optimum wellbore conditions for running and cementing liner, conventionally, with 2 RH turbulators/jt to just above GOC. 12. We will be repeating all steps (though some will be deleted as K-06A/K-20A/K-19A results confirm) except where the attached document has been modified. Run tandem scraper/bit run to top of float shoe based on results of prior 2 wells. This will be test number 4, unless the Asset Engineer decides to drop this on this well. One objective of this cement technique is to eliminate this cleanout run. 13. Run and cement 4.5" liner with the modified conventional program from K-06A/K-20A/K-19A (attached). Displace cement with 150,000 cps/5% Lubetex/6% KC1 perf pill = to liner volume plus 30 bbls excess pill for cement pusher pill. Displace pills with circulating Quickdril-N. Reference procedure for rig floor cement manifold setup to divert cement wash water to slop tank, avoiding cement shoe contamination or contamination to perf pill, and minimizing shut down to a few minutes. After plug bumps, and liner hanger and liner top packer are set, keep 1000 psi on drillpipe/liner. When you rotate 6 turns to the right and release from setting tool, the 1000 psi and the 30 bbl 150,000 LSRV/5% Lubetex, lead fluid, will act as a pusher pill to start moving the excess cement up the annulus. Pump at max rate set back down on liner top with slack weight of 40K to confirm liner top packer set, while circulating at max rate (with C-2 running tool only) Test liner lap to 3000 psi. Follow recommended practice for liner top 150' inside 7". While circulating out the excess cement, stay on pit fluid until you get clean returns and then circulate to clean seawater. 14. 150,000 cps 5% clarified Xanthan 6% KC1 perf pill inside liner is to prevent sticking perf guns during 100 psi underbalanced perforation on K-19A and to minimize formation damage, especially from fluid loss of inhibitor-treated brines, and to avoid sticking guns in influx of perf debris. POOH for perf guns. Run DPC Halliburton 2-3/4" RDX DP (12.5 gm), 4 spf, random orientation, 60 degree phasing perforating guns with Champ Perf packer. Perforate 100 psi underbalance. (Perforating memo will be distributed after logs, identifying intervals and procedures.) POOH & lay down guns. 15. Complete well with 4 1/2", L-80 tubing, Baker 4.5x7" S-3 packer set at 9320 MD (150' inside of window of 7" at 9470'. Completion string will include (4) GLM's and WOA tailpipe assembly, WLEG spaced & stung into top of liner tieback sleeve, and modified X nipple profile instead of SSSV. (Note: Have Camco pin the RP for 2400 psi nominal instead of 2900 and paint with white stripes to denote change. When testing tubing to 3500, only bleed tubing to 2000 psi prior to testing IA to 3000 to leave a 1000 psi differential across RP and prevent shear. Carefully bleed off IA & tubing pressures to avoid shearing RP. Contact ODE and Camco for details when you get to this step or reference attached document (also in rig files). This is our fifth well on which we have utilized this modified procedure with solid success. Space WLEG to place inside of 4.5" liner tieback sleeve when tubing is landed. Pull up and reverse circulate filtered seawater with Corexit @ 25 gaul00 bbls. 16. Position WLEG inside 4.5" tieback sleeve, land tubing and drop packer setting ball. Set the packer and test the tubing to 3500 psi for 30 min. Only bleed to 2000 psi. Test annulus to 3000 for 30 min. Slowly bleed tubing and record pressure differential when RP shears. Do not freeze protect yet. 17. Install TWCV in the tubing hanger and test from the annulus to 1000 psi. 18. Nipple down BOP equipment. 19. NU and test tree to 5000 psi. (Notify AOGCC in advance to witness or waiver) Pull TWCV. 20. Displace the annulus with diesel to 2000', overdisplacing sufficient volume through top GLM to freeze protect tubing to 2000', chasing with seawater. Install BPV, test from below, and secure the tree. 21. RDMO, pick up matting boards and herculite, clean area, perform a post rig site inspection with Pad Operator, and handover/release rig to Production. 22. Notify PE' s that tie-in will require dual P-Pilot to complete and put well on production.
