Transocean to scrap rig Jack Bates in December

Vol 22, PW 4 (29 Nov 18) Exploration & Production

ONGC is preparing to release two offshore rigs currently drilling at its KG-DWN-98/2 block: Transocean-owned semi submersible Jack Bates and Aban Offshore's deepwater drillship Aban Abraham.

Bates is expected to come off contract mid-December when she finishes and plugs well PDM-F, spud in early November in water depths of 474 metres before the Blow Out Preventer (BOP) was lowered on November 15. After Bates is released she will be moved offshore Kakinada and from there to the Alang ship breaking yard in Gujarat.

ONGC had hired Bates on July 8, 2016 at $127,000/day on a two-year contract. Also at the same block, Abraham is expected to come off contract on November 30 after cement plugs are lowered into well A-2-B in water depths of 683 metres.

Well A-2-B at the Cluster 2 fields was earlier drilled by SSV Louisiana under a batch-drilling assignment and plugged for later re-entry. Abraham re-entered A-2-B on October 21 after installing the BOP.

Sources say ONGC has used Abraham to do Drill Stem Tests at well A-2-B. After Abraham is released, she will move to Kakinada and after three or four days begin her four day journey to offshore Sri Lanka where she will be 'warm stacked' (maintained as if on contract) off China-operated Hambantota port, awaiting her next contract.

ONGC hired Abraham on June 24, 2016 at $105,582/day for two years.
