Calvalley Petroleum Inc., Calgary, has started production from Hiswah oil field on Malik Block 9 in Yemen. Calvalley is the operator and has 50% working interest.

The Hiswah-6 horizontal well went on stream Dec. 10. Initial production is constrained to 2,000 b/d by the capacity of a terminal to which the oil is being delivered by truck. This bottleneck is expected to be relieved within 2 months, when Calvalley expects production of 10,000 b/d.

Calvalley is designing and building a pipeline that it expects to be operational in the fourth quarter of 2006.

Four other Hiswah wells are expected to be brought on stream during the next few months. Calvalley completed its fifth horizontal development well in the Sayun-Masila basin last month (OGJ Online, Nov. 21, 2005).

Calvalley estimates full productive capacity from existing wells on Block 9 to be more than 20,000 b/d. The company declared Block 9 commercial after four discoveries (OGJ Online, June 23, 2005).
