AED, as operator of Block L, Brunei, updated on the initial results of the Production Logging Tool (PLT) and other processes as part of the Lempuyang-1 well testing in Brunei, Block L.

Trevor Slater, Country Manager for Brunei said, "At least one sand in the Pink zone had been flowing small quantities of gas during the latter part of the test which confirms the presence of mobile hydrocarbons in the targeted clinoform sand package. We will now proceed to test the Blue zone which is located approximately 200m shallower than the Pink Zone."

The PLT was used to measure pressure and inflow opposite each of the perforated Pink sands. The logging run demonstrated that almost 90% of the water produced originated from a single 3 metre thick sand perforated near the bottom of the Pink zone, and only 10% from the upper portion of the Pink zone. The PLT confirmed high reservoir pressures consistent with those observed during drilling. The gas analysis shows a dry gas with a high C1 content, along with C2's through to C5's. There will be continued assessment of the source and nature of the gas from Lempuyang-1.

While, the gas rates from the Pink zone are low, the presence of gas in the Lempuyang prospect is positive. We are further encouraged by the quality of the reservoir sand. The high average permeability (100 mD) and significantly high abnormal pressures demonstrate that the reservoir can produce at much higher rates than previously thought. The targeted clinoform sands therefore warrant further evaluation in assessing the field potential.

Drilling information and petrophysical analysis suggests that the upper Blue zone has the strongest hydrocarbon potential within the entire Lempuyang-1 well. The Blue zone test is set to commence shortly, once additional testing equipment becomes available.
