Perth-based Baraka today said the land-drilling rig ZJ50LDB is still onsite at Heron-1 in Block 20 and as of yesterday, the operation was displacing drill mud in preparation for well testing.
In a drilling update, the company said the past week has been spent installing the test equipment and performing operational and safety checks.
“Based on hydrocarbon shows observed in the well and preliminary wireline log interpretation, the operator has identified two zones within the cased 12¼-inch hole which are considered worth testing,” Baraka said.
These test intervals are 2152-2159m in the Turionian limestone reservoir and 1856.5-1863.5m in the Lower Campanian sandstone reservoir.
“The main objective of these tests is to confirm the existence of movable hydrocarbons that, if present, may be produced at potentially economic flow rates," the company said
The testing is expected to take over a week to complete, as the two tests will involve the well being shut-in for pressure monitoring for several days.
The results of Heron-1 and its implication for the prospectivity of Block 20 will be assessed by the joint venture and a meeting will be held in early second quarter of 2007 to discuss the forward work program in the permit, Baraka said.
Interests in Heron-1 are CNPC (65%) and Baraka (35%).
