UK-based exploration and production company Block Energy has restarted production at well 16aZ, which is located at its West Rustavi field in Georgia.

The well was forced to cut back operations in April when production rates of 1,100bopd far exceeded the 325bopd target.

It returned to production averaging 360boe/d on varying choking sizes since 11 July.

Block Energy said that a minimum of 1,200 barrels of drilling fluid were lost to the well at the time of drilling and completion operations.

The company transports the produced oil to a Georgian Oil and Gas Corporation (GOGC)-owned facility, which is located 30km along the Khakheti motorway from West Rustavi.

Earlier this month, Block Energy signed an agreement with GOGC to gain access to the 90,000bbls storage capacity.

Preparations are underway for horizontal sidetracking of well 38Z, which is adjacent to well 16aZ.

The production of well 16aZ is part of the company’s fully funded £12m programme to realise West Rustavi’s potential, demonstrated by the test production rates of 1,100bbl/d.

Block Energy CEO Paul Haywood said: “The well produced exceptional test rates earlier this year and offers excellent netbacks of $35/bbl at $65/bbl Brent.

“With the resumption of production at well 16aZ, our fully funded back-to-back multi-well drilling programme continues to gather momentum.

“Three of West Rustavi’s other wells will also be sidetracked in the Middle Eocene structure, and two of them tested for their historic gas discoveries in the Lower Eocene.”

Meanwhile, the company continues to produce oil at its Norio and Satskhenisi licences, at an average production rate of 26boe/d.
