Transoceanآ’s first east coast well on 23rd February

Vol 7, PW 22 (28 Jan 04) Exploration & Production

Also proceeding to schedule is ONGCs deepwater drilling campaign on the east coast of India, despite some bar room gossip of technical problems with Transoceans deepwater drillship Discoverer Seven Seas.

PETROWATCH learns, however, that the rumours are exaggerated. Rig inspectors from ModuSpec are on board Seven Seas carrying out an audit and have raised outstanding issues of equipment that needs replacing but nothing thats a showstopper, we learn.

Its routine stuff, nothing major. On 23rd February, Seven Seas hopes to spud its first well at the KG-OSDW/DW block sitting in the Krishna Godavari basin offshore Andhra Pradesh, kicking off the second leg of ONGCs deepwater drilling programme.

After leaving South Africa, the Dynamically Positioned Class II drillship will sail into Indian waters from Sri Lanka and reach the Indian port of Kakinada on 14th February. Depending on the weather it could reach a couple of days earlier, or a couple of days later, we learn.

Transocean has informed us that it plans to get all necessary clearances like defence and customs from Kakinada itself, reveals ONGC. For Transocean, this should be a formality.

It has already been through this routine with Discoverer 534 when it drilled in the same area for Reliance. At present, the Transocean rig is in Dubai loading logging tools and well testing equipment.

ONGCs deepwater team will inspect the material at Kakinada and then the ship will proceed towards the location. KG-OSDW/DW sits in water depths ranging from 1,100 metres to 1,800 metres.

At her first location, Seven Seas will drill in water depths of 1,470 meters. The first one is a directional well with a vertical depth of about 3,850 meters.

Earlier, ONGCs deepwater drillship Sagar Vijay drilled two wells at 900 metres water depth reaching up to 2,107 meters below the seabed. Our team is now interpreting logs acquired from the two Sagar Vijay wells, adds ONGC.

We will soon know at what depth hydrocarbons can be encountered.
