Ramba Energy – an oil and gas exploration and production company with interests in Indonesia – has discovered 222 feet of gross pay at the Lemang Block, onshore Sumatra, Indonesia.
Testing results from the Selong-1 well – the first well to be drilled by Ramba at the Lemang Block – flowed up to 790 barrels of oil per day from a depth of 5,375 feet to 5,385 feet in the Lower Talang Akar Formation and up to 16.8 million standard cubic feet of natural gas per day at a depth of 4,735 feet to 4,751 feet from the Upper Talang Akar Formation.
The Selong-1 well, drilled using the 1500HP NOV Ideal Rig to a total depth of 6,600 feet, has been temporarily suspended as a discovery well. More tests and possibly additional zones may be tested in the future, the company disclosed in a statement.
Commenting on Selong-1's results, Ramba’s CEO David Aditya Soeryadjaya said, "With testing results from the Selong-1 well delivering up to 3,500 barrels of oil equivalent per day, we believe this increases the probability of success for the Akatara-1 well. The positive result also increases our confidence in the commercial potential of the Selong and Akatara prospects, and the overall potential of the Lemang Block."
Ramba's second scheduled exploration well is the Akatara-1 well, which the company plans to complete in early 2013. Excluding mobilization, the drilling of Akatara-1 is expected to take around 26 days, with a possible additional 25 days for testing and analysis, Ramba revealed. Akatara-1 will also be drilled using the 1500HP NOV Ideal Rig.
DeGolyer & MacNaughton, a petroleum consultancy, estimates the Lemang block to hold gross recoverable prospective resources of 511 million barrels of oil and 468 billion cubic feet of gas.
