The Cladhan South prospect is located on Blocks 210/29c and 210/30b. Sterling Resources holds 12.5%; TAQA holds 12.5%; Wintershall holds 25%; Valiant Exploration holds 30%; and Agora Oil and Gas holds 20%.
Cladhan South is an Upper Jurassic channelised sand play immediately to the south of the existing Cladhan discovery with gross prospective resources estimated internally by Valiant to be 13 MMboe. The well was drilled by the Sedco 704 (mid-water semisub). The well encountered multiple Upper Jurassic sand channels on prognosis, none of which were thought to be hydrocarbon-bearing. A further South Cladhan exploration well, 210/29c-5, spudded in November 2012 failed to encounter hydrocarbons. Development throughout 2014 continued according to the FDP, with two high-angle production wells and one high angle water injection well. The first development well, P1, encountered a 2,300 ft reservoir with 815 ft net pay. The P2 development well met thinner than anticipated sands at the bottom of the well and little pay. Drilling also penetrated the suspended 210/29a-6 well and sidetracked it to the eastern portion of Cladhan field.
Cladhan reached first-oil during the fourth quarter of 2015, but output was lower than anticipated with a “marginal contribution” during the quarter. Production throughout the first half of 2016 averaged 8.756 bpd with average uptime of 82%
