Oil major Shell is planning to start exploration drilling offshore Tanzania later this year, according to partner Ophir Energy.
The US$20 million drilling program, due to start in Q4, will comprise two wells on Blocks 1 and 4 and target 1 Tcf of gas, says Ophir. Shell became operator on the blocks after taking over BG Group earlier this year. The well on Block 1 will target Kitatange, with an estimated mean recoverable volume of 1.1 Tcf.
The well on Block 4 will target Bunju with an estimated 1.4 Tcf. The wells, which have been given 40 per cent chance of success, will fulfill outstanding exploration requirements on the licenses.
FEED is expected to start following the completion of the LNG site acquisition, the geotechnical investigations and engineering studies. Concept selection for the upstream part of the project which will determine the configuration and production rates from each of the fields.
Ophir’s COO Bill Higgs said: “Shell sees this as an LNG project that ranks well in their portfolio. Shell is currently looking for ways to reduce the cost structure for the LNG project.”
Meanwhile, Ophir has reduced the expected cost to first gas on its Equatorial Guinea Fortuna floating LNG project from $450-500 million down to US$450 million. A final investment decision is expected by year end 2016.
Ophir is also planning to drill its first well in off the Ivory Coast, in deep water. The Ayame prospect is the main target, containing 240 MMboe expected recoverable resources with 80% chance of success.
The firm is also considering drilling in deep water offshore Gabon, in an area seen as an emerging oil play on the west African margin.
It is also looking at possibly drilling in deep water offshore Myanmar, in the Rakhine basin, in 2017.
