Discoverer spuds another ONGC well

Vol 10, PW 24 (05 Apr 07) News in Brief

Transocean deepwater drillship Discoverer Seven Seas has begun drilling another well for ONGC.

This well is on eastern offshore Mahanadi basin NELP-I block MN-DWN-98/3. Well A-1 is the first on this block and was spud on 28th March in 1100 metres water depth and has been set a TD of 2465 metres.

Says an industry source: “The conductor casing has just been set and mud is being circulated.â€‌ ONGC is hoping for a hydrocarbon discovery at this well, in line with other recent finds in the Mahanadi basin.

By the end of this month Discoverer Seven Seas will be the only charter-hired deepwater rig with ONGC after Belford Dolphin is de-mobilised. When DSS was hired many faulted the choice of what was described as, “an ageing, leaky boatâ€‌.

Despite several mishaps, Discoverer Seven Seas has made more discoveries for ONGC than the ultra-modern Belford Dolphin. Discoverer’s contract ended in February this year, but ONGC has re-hired her for another three years.
