RoyalGate Energy said it will drill the Tulip Upper Isongo discovery and Tulip Massive Isongo prospect in Equatorial Guinea.
The Z-1 well is set to be drilled in the first quarter of 2016 close to the location of previous offset wells and in the vicinity of known producers.
Located to the north of Bioko Island and south of the Marathon Oil-operated Alba field, Block Z has estimated gas reserves of more than 3.6 tcf.
President of RoyalGate Energy Frank Ene said: “We are proud to announce the drilling program for the Z-1 well.
“This is the continuation of what we see as a long term partnership with Equatorial Guinea and we see a lot of development potential for Block Z.
“We are bullish about the prospectivity of this block and our other assets in Equatorial Guinea.”
A 600 square kilometer 3D seismic campaign in 2014 showed the Tulip, Daisy, Buttercup and Sunflower prospects.
Block Z also contains the Gardenia discovery, made in 2004.
RoyalGate Energy entered the block as operator in 2013.
The company is scheduled to hold a technical committee meeting for Block Z with the Ministry of Mines, Industry and Energy and selected contractors on October 22 in Djibloho, Equatorial Guinea.
