Here you go dai:
A 36" x 42" hole is planned to be drilled from 508 m to 574 m TVD. After completion of the section, a 30" x 36" conduit is installed and cast with cement.
The section will be drilled with seawater and periodically cleaned with highly viscous mud pellets. After drilling to the planned depth, the hole is displaced to 1.30 sg of water-based displacement fluid. Drilling cuttings and excess cement are discharged to the seabed.
A 26" hole is planned to be drilled from 574 m to 1,530 m TVD. After completion of the section, a 20" surface pipe with a wellhead is installed and cemented to the surface.
The section will be drilled with seawater and periodically cleaned with highly viscous mud pellets. After drilling to the planned depth, the hole is displaced to 1.30 sg of AQUA-DRILL water-based drilling fluid. Drilling cuttings and excess cement are discharged to the seabed. After the cement job is complete, a high-pressure riser and BOP will be installed on the wellhead.
If shallow gas is encountered, the 20" surface pipe with wellhead will be installed above the gas zone to be able to drill through the gas zone with the BOP installed on the well (option).
A 17 1⁄2" x 20" hole is planned to be drilled from 1530 m to 2113 m TVD. After completion of the section, a 17" extension pipe is installed which is cast with cement.
The section will be drilled with either AQUA-DRILL water-based or DELTA-TEQ oil-based drilling fluid which is gradually weighed up from 1.30-1.50 sg. Both fluid systems are included in the application.
A 16" x 17 1⁄2" hole is planned to be drilled from 2113 m to 2700 m TVD. After completion of the section, a 13" casing is installed which is cast with cement.
The section will be drilled with DELTA-TEQ oil-based drilling fluid which is gradually weighted up from 1.70 sg to approximately 1.80 sg.
A 12 1⁄4" hole is planned to be drilled from 2,700 m to 3,360 m MD / 3,270 m TVD. After completion of the section, a 9" cement-cast casing will be installed.
The section will be drilled with DELTA-TEQ oil-based drilling fluid which is gradually weighted up from 1.76 sg to approximately 1.80 sg.
An 81⁄2" hole planned to be drilled from 3360mMD / 3270mTVD to 3909mMD / 3824m TVD. The section will be drilled with DELTA-TEQ oil-based drilling fluid with a weight of approximately 1.80 sg.
If hydrocarbons are found, it is planned to install a 7" extension pipe in the well and perform a well test. The 7" extension pipe will be installed at approximately 3908 m MD / 3823 m TVD and cast with cement.
