A well drilled to assess potential of the western flank of Taq Taq oil field in the Kurdish region of Iraq is on production, reports Genel Energy PLC, London.
The TT-20z horizontal sidetrack well started production at an initial rate of 2,000 b/d through a 24/64-in. choke, boosting gross Taq Taq output to 15,500 b/d of oil.
Genel said it expects flow to increase from the TT-20z well, which produced during tests at a combined maximum rate of 4,000 b/d of oil through a 40/64-in. choke from three zones.
The rig has spudded the TT-33 well on the field’s southern flank.
In February, Genel reported that the TT-32 well on the field’s northern flank had begun production at an initial rate of 3,100 b/d of oil on a 24/64-in choke.
During tests, the well flowed from three zones at a maximum individual zone rate of 5,500 b/d through a 34/64-in. choke.
The well encountered the free-water level at 1,458 m, 29 m deeper than the predrilling estimate and 57 m above the original field-wide free-water level.
The oil column at the TT-32 well location is 169 m.
An earlier well on the northern flank, TT-29w, went onto production late in 2017 after flowing oil at individual zone rates up to 6,400 b/d through a 40/64-in. choke during tests of six zones in Cretaceous Shiranish and Kometan reservoirs (OGJ Online, Mar. 31, 2017).
The well went online at a restricted rate of 3,200 b/d of oil from the Lower Shiranish reservoir. The oil-water contact in the TT-29w well is at least 45 m deeper than expected before drilling.
Genel jointly operates the Taq Taq production sharing contract, with a 44% working interest, with Addax Petroleum, a Sinopec Group company.
