HOUSTON, Mar. 14 -- Toreador Resources Corp. and partners have made two additional gas discoveries in the South Akcakoca subbasin in the Black Sea off Turkey.
The Atwood Oceanics Inc. Southern Cross semisubmersible drilled the Guluc-1 exploration well on a separate structure on the same geological trend as the recently announced Akcakoca and Akcakoca East discoveries (OGJ Online, Feb. 8, 2007).
Guluc-1 encountered gas-bearing sands in six zones between 1,226 m and 1,453 m TVD in the same Eocene-age Kusuri formation as in the other wells in the South Akcakoca subbasin. The well tested 17 MMcfd of gas from 37 m of perforations across all six zones on a 48/64-in. choke with flowing pressure of 1,180 psi.
The Alapli-1 exploration well, drilled using the Prometheus jack up, is on a separate structure to the northeast of Akkaya field currently under development. Alapli-1 encountered gas-bearing sands in three zones between 1,068 m and 1,242 m TVD. The two lower zones, with 12 m of net pay, tested 6.8 MMcfd of gas on a 32/64-in. choke with a flowing pressure of 1,064 psi. The upper zone at 1,239 to 1,242 m TVD will be tested soon.
The Atwood Southern Cross rig, having completed its initial three-well program in the South Akcakoca subbasin, will now be released to work for another operator off Bulgaria. And the Prometheus jack up will drill a well for one of the partners in another permit area before coming back to the South Akcakoca subbasin to set the Ayazli tripod and topsides in late April.
The topsides for the Akkaya production tripod already have been set and secured.
