The American trade corporation, ERHC announced that preliminary analysis of the Tarach-1, situated in Kenya’s Block 11A, drilling results reveals encouraging information for further exploration, Oil News Kenya informed.
ERHC’s President and CEO, Peter Ntephe, said that the well came across oil shows and highly-elevated gas reading, indicating the presence of a working petroleum system with the strong possibility of significant hydrocarbon generation, according to Ecofin Agency. The well encountered two different hydrocarbon charged intervals, the first extending more than 100 meters.
The Tarach-1 exploratory well began drilling activities in April and has been plugged after drilling was completed as post-well analysis continues. The objective of the well was to establish a working petroleum system and test a three-way structural closure trapping against a North-South trending normal fault. Furthermore, Tarach-1 was drilled from a 20-inch surface casing through intermediate casings down to 2,442 meters and set a seven-inch liner down to total depth (TD) of 3,000 meters with the Tarach-1 prospect’s mean estimate of oil prospective unrisked resources earlier estimated at 66m barrels.
Block 11A is operated by CEPSA with 55% alongside State-run National Oil Corporation of Kenya (NOCK) and ERHC with 10% and 35% respectively.
