Sonoro begins drill stem test at LG-1 Up-dip well

By Romel S. Gurky

Calgary-based junior oil and gas firm Sonoro Energy Ltd. provided on Tuesday an update to drilling operations at its LG-1 Up-dip well, with drill stem testing having commenced on the Budong Budong Production Sharing Contract in West Sulawesi.

The company said in a statement that following successful logging of the open hole section from 297m to 549mKB, it has identified prospective oil and gas zones for further testing to determine indicative potential flow rates and reservoir conditions.

Sonoro said the testing intervals have been further approved by upstream oil and gas authority SKK MIGAS. ?This Testing program has been specifically designed to meet data gathering requirements to support a potential plan of development to the government should results warrant it,? the company said. The intervals currently being tested are between:
? 474m to 495.5mKB;
? 375m to 401mKB; and
? 333m to 353mKB.

Note that as there are several stacked sand layers in between claystone, these intervals do not reflect an actual net sand pay but the areas over which the Testing packers are expected to be set.

?The commencement of testing should not be interpreted to mean that commercial rates may be achieved. Final test results of oil and gas productivity, if any, are required to help the company in assessing commerciality of the project,? Sonoro said.
