Horse Hill Developments Ltd. (HHDL) plans horizontal drilling this year at Horse Hill field, which is undergoing an extended production test near Gatwick Airport outside London, reports parent company UK Oil & Gas PLC.

HHDL will drill the Horse Hill-2 horizontal well into the Upper Jurassic Portland sandstone and a horizontal sidetrack into the Upper Jurassic Kimmeridge limestone in the Horse Hill-1 discovery well on PEDL 137 (OGJ Online, Oct. 27, 2016).

The company has restarted flow from a 114-ft vertical perforated Portland section in Horse Hill-1 after a 6-month shut-in. The rate is being held at a stable rate of 208-218 b/d of oil with no water, below the calculated optimum sustained rate of 362 b/d.

The Weald basin well has produced more than 5,100 bbl of Portland oil to date.

As Portland flow resumed, Kimmeridge test production in Horse Hill-1 was shut in for a further long-term pressure build-up test. The well has produced more than 30,200 bbl of 40° gravity oil from the formation with no water.

Most of the test production has been trucked to Perency’s Hamble oil terminal.

Portland test production will be switched to Horse Hill-2 when drilling of that well is complete.

Kimmeridge test production in Horse Hill-1 then will resume followed by further long-term production testing of the planned Horse Hill-1z sidetrack.
