WELL SUMMARY

The Semi-submersible MODU Ocean Bounty commenced the rig move from Bayu-3 at 10:30hrs on 21st April 1996, and arrived on location at Jahal-1 on 22 nd April 1996. A second approach to the Jahal-1 location was required as the rig drifted too far of line on the first attempt. Anchors were run. A Kenter link on anchor number 4 parted and was rejoined on the rig.

Jahal-1 was spudded on 23 rd April 1996 (the sea floor was tagged at 427.3m). The 36 in hole was drilled with a 12.25 in pilot bit/36 in Kvernex heleopener combination. The hole inclination at TD (467m) was 2.0 with MWD survey and 1.25º Totco survey. The 20 in/30in casing and PGB were run and cemented at 465m. The rig was repositioned to hold the PGB angles to 1.5º port and 1.75º port/fwd while WOC. Upon repositioning the rig, the PGB angles were 1.75º port and 2.0º port/fwd. While drilling the 17.5 in wellhead was run and cemented at 1040.31m. The BOP stack was run and tested.

The cement plug was set in the 8.5 in hole section from 3355m to 3250m. a kick-off cement plug was set from 2900m to 2770m. The hole was displaced back to 1.055G SBM and the hole was sidetracked to 20º inclination at an azimuth of 190º. The sidetrack section was drilled to core point at 3303m MD using two steel tooth bits, one PDC and one TCI all run PDMs.

The well plugged and abandoned. Anchors were pulled and the rig was released at 02.30hrs on 3rd june 1996.
