REMARK I OBSERVATION

Bottoms up sample from 2216m confirmed basementcuttings. 12 1/411 hole appears to be drilled 4m shallow.Loggers depth on run #1 showed TD to be 221 Om and 95/8" shoe to be at 1878m as expected.

Array Sonic module failed when tested on surface. thiswas replaced by a SHC sonic tool.

SOLUTION I RECOMMENDATION

8 1/2" bit may have caught a ledge when washing tobottom and when rotation started this may have starteddrilling new hole from ledge - this could explain why thelogging tool will not get any deeper and we have aloggers TO 10m higher than the initial drillers TO.

Please nnd attached the DDR for 23n.1 June 1998. The daily cost calculation included on this reportcontains 50% of the rig mobilisation from Singapore and Seychelles, 50% of the de-mobilisation of therig and also mob/demob of supply boats. This accounts for the large incremental increase on to-daysreport.

Repaired washed out air fine with pre-fabricated sectionwhile handling tools for new BHA and fe-aligning Diverter.New air line installation fabricated to maximize distancefrom Guide lines in order to avoid reoccurrence.

Vhile RIH after repairs to air line, the driller pumped up(he compensator system, as both the compensator andguide wire tensioning system work off the same repairedair line which had been bled off. When bedding in the bitand trying to adjust the compensator, however,insufficient air pressure to the compensator was availableto hold the string, allowing the bit to spud into the btm ofthe hole wi 40klbs.

Summary of DP washouts: Washout # 1 fl White Ibis, onrep.16, was reported as 2 ft below tool jt (0.61 m), not 2m,7 std below RT. Washout # 2, rep 19, was 0.74m belowthe tool jt (box) on the middle jt of std 8 off btm. On theYolla well, washout # 1, rep # 35, was 0.61 m below tool jt(box) on 16th std below RT; washout #21 rep # 35, wasO.61m above tool jt (pin) on the 22nd std below RT. Allare strikingly similar, Digital photos of the 1st 3 havealready been sent to Premier, Geelong (4th in mailbag).NB: the internal upset on this pipe is +/- a.6m from thetool jt.


Diverter alignment: This is the old stlye diverter, withouta ''V'' shaped dog which locks into a corresponding "V'recess, preventing torque-ing out of alignment.Previously here, they used a cover plate and bolted thisdown, but experienced problems pulling the bolts due tothe torque forces against them.The air storage bottle bank had been bled off for repairs,but the compressors slowly provided enough air topressurize the string compensator while RIH.Unbeknownst to the driller, the guidewire tensioningsystem was pressured up before the system'saccumulator bottles were fully charged. This had theeffect of bleeding off the compensator air. Problemsolution: communicationlll and separate air supplies(compressors) for each system.

Repaired washed out air line with pre-fabricated sectionwhile handling tools for new BHA and re-aligning Diverter.New air line installation fabricated to maximize distancefrom Guide lines in order to avoid reoccurrence.

While RIH after repairs to air line, the driller pumped upthe compensator system, as both the compensator andguide wire tensioning system work off the same repairedair line which had been bled off. When bedding in the bitand trying to adjust the compensator, however,insufficient air pressure to the compensator was availableto hold the string, allowing the bit to spud into the btm ofthe hole wI 40klbs.

Summary of OP washouts: Washout # 1 fl White Ibis, onrep.16, was reported as 2 ft below tool jt (0.61 m), not 2m,7 std below RT, Washout # 2, rep 19, was 0.74m belowthe tool jt (box) on the middle jt of std 8 off btm. On theYolla well, washout # 1, rep # 35, was 0.61 m below tool jt(box) on 16th std below RT; washout #2, rep # 35, was0.61 m above tool jt (pin) on the 22nd std below RT. Allare strikingly similar. Digital photos of the 1st 3 havealready been sent to Premier, Geelong (4th in mailbag).NB: the internal upset on this pipe is +1- O.6m from thetool jt.


Diverter alignment: This is the old stlye diverter, withouta "V' shaped dog which locks into a corresponding "V"recess, preventing torque-ing out of alignment.Previously here, they used a cover plate and bolted thisdown, but experienced problems pulling the bolts due tothe torque forc~s against them.The air storage bottle bank had been bled off for repairs,but the compressors slowly provided enough air topressurize the string compensator while RIH.Unbeknownst to the driller, the guidewire tensioningsystem was pressured up before the system'saccumulator bottles were fully charged. This had theeffect of bleeding off the compensator air. Problemsolution: communication!!! and separate air supplies(compressors) for each system.

All 3 wash outs during the 2 wells have occurred inapproximately the same area of the jt, while the jt was inthe same part of the upper string. where the jts aresupporting the max. weight. This supports the hypothesisthat corrosion is not the mechanism causing these washouts, but perhaps the jts have not received the correctpost·heat treatment after the fusion of the pipe & the tooljoint. As a result, this area of the jt is now hard & brittle,Ind is not flexing to the same degree as the remainder of

I the joint.


Laboratory of the washed joints is recommended toconfirm the mechanism involved.

REMARK 1OBSERVATION

Unable to jump ROV due to lack of response to surfacecommands. ROV unit had been tested daily -all okay- butintermittent fault developed as it was prepared to jumpimmediately prior to spUdding. Troubleshooting revealedthat the problem may lie in the control wires in thetelemetry system between the unit's computer and that inthe control cabin.The Anderdrift tool was checked and pulses recordedwhile MU the BHA, before spudding. Upon drilling the 1stsingle into the seabed, a survey was attempted and onlyone pulse (Sdeg) was recorded. When the survey wasrepeated, no pulses were observed. Subsequentattempts at surveys .were also unsuccessful, as no pulseswere observed.

SOLUTION 1RECOMMENDATION

After discussion with town, it was decided to spud "blind"as weather conditions were good and the BHA in themoonpool was hanging vertically. ROV repairs would beeffected before the interval was drilled and the BHAready to be pulled above the seabed.

The internal flask may have been damaged or pluggedwith debris while spudding. The backup tool will need tomade up into the string in order to break out the sub anddress the tool with a new flask.
