ONGC is testing troubled deepwater appraisal well KT-2 at KG-DWN-98/2 after reaching 5425 metres TD.

“We found oil traces,” confirms a source. Results will be sent to the DGH soon.

” Transocean’s GSF 140 has spent more than a year drilling KT-2 - a HP/HT well beset by problems. On June 18, ONGC carried out Drill Stem Tests in a 322-metre zone between 5103 and 5425 metres.

GSF 140 is expected to move to block G4 next, but ONGC has told Transocean to wait. At the same block, GSF Explorer continues to drill development well KG-DWN-98/2-J-AA in water depths of 90 metres.

By June 18, Explorer drilled J-AA to 5827 metres of its targeted 6423 metres TD. Also on the east coast, Noble drillship Noble Duchess is drilling a well at the G-1 nomination area near G-1-9, which had a high profile gas leak in 2012.

Duchess spud appraisal well G-1-9#sub on May 20 in water depths of 282 metres and will drill it to 2267 metres TD. By June 18, Duchess drilled G-1-9#sub to 409 metres.

"We're targeting younger Pliocene era formations," says ONGC. Transocean-managed semi-submersible Actinia continues to drill appraisal well GS-29-10 at east coast nomination block GS-29.

By June 18, Actinia had drilled GS-29-10 to 2412 metres, another 127 metres since our last update on May 5.
