LGO to log first Goudron redevelopment well

Leni Gas & Oil PLC (LGO), London, will run electric logs to total depth of 4,212 ft in its first well of a 30-well redevelopment program for Goudron oil field in Trinidad and Tobago.

The well, GY-664, encountered oil-bearing Miocene-Pliocene sandstones with thicknesses totaling an estimated 1,300 ft: more than 350 in the Goudron formation, about 720 ft in the Gros Morne formation, and 100 ft in the Lower Cruse formation.

LGO will set 7-in. casing after logging.

It’s doing the work under an incremental production service contract it acquired for reactivation of the field in October 2012, when production was less than 40 b/d. LGO it has produced more than 100,000 bbl from the field since then.

The license, in which LGO holds a 100% interest, covers 2,875 acres near a wildlife sanctuary in southeastern Trinidad. The field was discovered in 1927 and developed by Texaco during 1956-86. It has direct access to a pipeline to state-owned Petrotrin’s 168,000-b/d Point-a-Pierre refinery.

LGO has reactivated 70 old wells and raised Goudron field output to about 300 b/d.

In an April presentation, the company said that in addition to reactivating wells it had refurbished storage facilities and doubled sales-tank capacity, repaired bridges and roads, installed a new camp, extended and restored electrical power, and built water-treatment facilities.

It its budget LGO assumes output of 65 b/d/well from Goudron redevelopment drilling. The company says some wells might produce as much as 160 b/d each.

On pump, the field has produced a total of less than 4 million bbl from primary production.

LGO said proved and probable reserves in currently productive zones are estimated at 7.2 million bbl. Proved, probable, and possible reserves are 30 million bbl.

Contingent resources, based on enhanced recovery, might be as high as 60 million bbl, LGO said.
