LONDON – Serica Energy plans to drill at least two exploration wells next year offshore the UK.

The company has a 100% interest in contiguous part-blocks 210/19a and 210/20a. Both are adjacent to the producing Otter oilfield.

Serica has identified four oil prospects on the blocks. Two of the Jurassic Brent group candidates are down-faulted traps, and another is a conventional Brent fault block. The fourth is in a Jurassic reservoir known as the Home Sand.

The company plans to drill a well to test the South Otter prospect, but first needs to find a farm-in partner.

In the East Irish Sea off northwest England, Serica holds 65% of blocks 113/26b and 113/27c. It plans to drill a well on the Sherwood sand Doyle gas prospect in the northern part of 113/27c.

Offshore western Ireland, Serica has 50% of Slyne basin blocks 27/4, 27/5 (west), and 27/9, containing the Liffey and Boyne prospects. In 2009, Serica discovered shallow Jurassic sub-commercial oil while drilling the Bandon exploration well 27/4-1. At Liffey and Boyne, there is evidence of deeper Jurassic oil and gas potential.

The company has acquired site survey data ahead of a drilling program to test these prospects, and again is seeking a farm-in partner.

Finally, in the northeast of the Rockall basin, also off western Ireland, Serica has 100% of blocks 5/17, 5/18, 5/22, 5/23, 5/27, and 5/28, which hold the 30-sq km (11.6-sq mi) Muckish prospect in 1,450 m (4,757 ft) water depth. In this case too, Serica hopes a farm-in will spur drilling action.
