You should be able to find all of the operational specifics in the remarks section at the end of the report. As far as the pit gain we saw when we drilled out the top plug, it is hard to say for sure how we got the 14 bbl pit gain, but our best guess was trapped pressure underneath the plugs. The shoe track was full of hard cement and the casing test was rock solid, so it appears we somehow introduced air in the system below our top plug when we dropped it. We did not find anything unusual with out cement job, but it was definitely a great catch by the driller to stay on top of it when drilling out the plugs. As the reports say, after we had killed the well, we continued to drill out the shoe track, displaced to 8.8 ppg LSND, and had no further issues with the well flowing.

I was going through the drilling reports and couldn't figure out how you get pressure tested surface casing, then get 14 bbl gain on pits before drilling out the shoe track. Strange incident. Also on the surface cement the report is not clear on how much cement was returned to surface. Can you clarify that ??

At p gg p 15:45 after drilling 1', Driller noticed a 12% increase in flow and a 12 bbl pit gain. Flow checked well, well was flowing. Well was shut in using annular. Initial shut in pressure was 10 psi on drill pipe and 0 psi on Casing. Final shut in pressure was 20 psi on drill pipe and 10 psi on casing. Inform AOGCC u Representative Chuck Scheve the well was shut m. Circulate Bottoms up through the choke, no change in drilling fluids. Weight up drilling fluid from 9.3 ppg to 9.5 ppg. Monitor shut in pressure, 0 psi drill pipe, 0 psi casing pressure. Open annular and monitor well, well static. Test casing to 1,000 psi, good test.

Based upon calculations below, BOP equipment will be tested to 3,500 psi. Due to surface pressures not - exceeding 3,000psi it will not be necessary to have two sets of pipe rams installed at all times. BOP regular test frequency will be 14 days, with a function test every 7 days. Diverter, BOPE and drilling fluid system schematics on file with the AOGCC. Variance Request • To avoid the risk of plugging the flow line with large rocks and wood encountered while drilling surface hole, it is requested to drill without a flow paddle for the first portion of the surface hole. After drilling past the larger rocks and wood sections, the flow paddle will be put back in the flow line. • To mitigate any risk involved with no flow paddle, the following steps will be taken while the flow paddle is removed from the flow line. Ensure PVT alarms are used and the pit levels are accurately monitored for any pit gain. Visually look down the riser during connections to ensure the well is not flowing.

The target sands in the Schrader are potentially over - pressured do to nearby water injection from L -215i and L -216i. A maximum pressure of 9.3 ppg EMW can be expected in the N and 0 Sands. II. Hydrates and Shallow gas A. Gas Hydrates are expected at L -pad from the SV5 thru the SV1 sands below the base of the Permafrost. Setting surface casing below deepest SV1 sand hydrate zone will isolate gas bearing intervals from the intermediate section. If hydrates are encountered, recommended practices and precautions for drilling hydrates should be followed in the surface hole. III. Lost Circulation /Breathing A.

Nabors 7ES Close Approach Analysis We have examined the potential intersections of subject well with all other potentially conflicting wells, according to the BPA Directional Survey handbook (BPA -D -004) dated 09/99. Method of analysis: 1. A list of wells to be analyzed is created in Compass by performing a global scan with an initial search radius of two hundred feet with an increment of one hundred feet for every one thousand feet of measured depth in the subject well. 2. Wells are analyzed using the Compass Anti - collision module (BP Company setup) with major risk safety factors applied. For problem wells that are plugged and abandoned or that can be shut in, risk -based safety factor may be used, with client notification. 3. All depths are relative to the planned well profile. Survey Program: Instrument Type Start Depth End Depth GYD GC SS 28.50' and 1000.00' and MWD 1000.00' and 2400.00' and MWD + IFR + MS 1000.00' and 13825.61' and Close Approach Analysis results: Under method (2), note. All drilled wells pass major risk. All data documenting these procedures is available for inspection at the Drilling & Measurements Directional Planning Center. Close Approach Drilling Aids to be provided: A drilling map and traveling cylinder will be provided.

He was going to look into it and get back with me, but it sounds like if they did and it incorrectly, then most likely there had been something incorrect about the landing procedure. Normally they will latch into the collet with the LEM, pull out of the collet to ensure they are landed correctly, then latch back into the collet and resume the setting sequence. Ken said he will look into it and get back with me. When I spoke with SLB yesterday, they said the yield for 11.0 ppg LiteCrete is 1.84 cuftlsack because they have recently begun measuring their yields slightly differently. Instead of measuring the yield by the sack of cement, they have been loading out their cement by the sack of blend. This means their yield will include all the dry additives in the slurry. With a yield of 1.84 cuft/sack, the volume of LiteCrete will be 667 cu ft or 363 sacks. Please let me know if you have any further questions. Also, I forgot to mention yesterday, but please treat the Spider Map below as confidential as it shows our OWC. The geo told me this is probably the easiest map to read. Let me know if you need any further clarification.

On the MWD for setting the LEM I was going by experience over at CPAI. They had an instance where the LEM landed 180deg out of alignment. It can happen though not very likely. With that many LEMs stacked on top of each other going back to fix something would be costly !!! Oh... the 11 ppg Litecrete yield still doesn't add up for volume needed. Either the yield is off or the total sacks required. Should have PTD approved shortly.

We are using the Shear Disk to isolate the upper Nb sands so we can flow back the Nb sands first, then break the shear disk and flow back the lower laterals. The Magnum Shear Disk is a ceramic disk that can be sheared with slickline, and is capable of 10k psi differential. The USIT will be used to evaluate cement quality and ensure we have good cement to mill our windows. This will be a critical step in the well. We are not planning on taking any "special steps" to mitigate casing wear. Casing wear has not been a problem for any of our multi -lats, especially since we are able to drill through the Schrader formation so fast. V -207 was a multi -lat drilled last year with roughly the same footage and we did not have any problems with that well. Also, the natural lubricity of the Oil -based mud should help us with minimizing torque and casing wear. I double checked with SLB today and he corrected me with the yield of 1.11 cuft/sack for the 11.0 ppg LiteCrete slurry. The correct yield should be 1.84 cuft/sack for this slurry. Sorry about the typo and let me know if you have any further questions about this. We know the LEMs are oriented properly because there is an orienting sub above the LEM that lines up the LEM correctly inside the hook hanger and latches it to the Hook Hanger. It is a simple, yet reliable system. Baker has designed 4 different LEM profiles that will allow us to access 4 different legs for post -rig work The fifth widow will utilize a Sliding Sleeve design, so we will be unable to access that let after the well is completed. I will get you a spider map tomorrow (as soon as the geologist gets it to me). For now, I have attached one from the Tech package. Please let me know if you have any further questions.

I have a couple of questions and comments. 1) There is mention of a USIT log to be run (requested by asset) but I don't see it in the general procedure. 2) On that note .. with all the drilling to be done are you considering a follow -up caliper or USIT log to look for casing wear in the 7 5/8 ". What are you doing to mitigate casing wear? 3) I noticed on page 4 in the 7 5/8" casing cement summary that the 11.0 ppg Litecrete yield is listed at 1.11 ft3 /sack. I believe there is a typo there.... 4) With this many LEM installations are you going to use MWD to insure they are set (oriented) properly? I need to catch up with Baker to see how they are doing this many Hook Hanger installs. I am not sure how the ISO sleeves and diverters will be indexed for the proper lateral with this many LEM's installed. If you have info on this new LEM system I would be appreciative. 5) I will approve the variance to remove paddle for first 1000' of surface hole. 6) Is there any surface view plot spider map available that shows all the laterals? This is certainly a ground breaking well. Good luck.
