Cooper Energy: Primary target flows oil in initial testing of Bunian-3 ST2 well

By Romel S. Gurky

ASX-listed Cooper Energy Limited announced Monday that testing of the Bunian-3 ST2 development well in Sukanti KSO, South Sumatra, has begun successfully with oil flows from the primary target TRM3 sand.

Following an initial cleanup period, the TRM3 sand flowed for 2 hours at a stabilised flow rate equivalent to 1,742 barrels per day of oil through a ? inch choke, with a flowing tubing head pressure of 500 psi, the company said in a statement.

?The flow consisted of oil and gas with no water. Measurements to quantify the gas rate are ongoing. The flow rate achieved was limited by the capacity of available surface facilities. Oil flows are being directed to a temporary production facility and produced oil is being trucked directly to market,? Cooper said.

The company added that further flow testing of the TRM3 sand is being conducted to gather additional data. On completion of the initial evaluation of the TRM3 sand, flow testing of the K1 sand will be conducted (refer Figure 1 schematic cross section following). Analysis of the increase in reserves will be completed after the completion of the production tests.

Cooper Energy Managing Director David Maxwell said ?these encouraging initial results are consistent with post drill expectations and will assist with the identification of additional reserves in this reservoir?.

The drilling rig was released on April 23 and has been moved off site while maintenance work is carried out prior to commencing the drilling of Tangai-5.

Joint Venture participants in the KSO Tangai-Sukananti Block are Cooper Energy Ltd (Operator 55%) and Mega Adhyaksa Pratama Sukananti Ltd (45%).
