HOUSTON — Flow test results from the Krabdagu oil discovery offshore Suriname confirm the need for appraisal drilling, said partner APA Corp.
The Maersk Valiant drillship drilled the KBD-1 well on Block 58, operated by TotalEnergies.
Test data collected from the Upper Campanian and Lower Campanian intervals suggest in-place reserves of respectively 100 MMbbl and 80 MMbl connected to the well.
The Upper Campanian interval delivered 32 m (105 ft) of net oil pay in good-quality reservoir with 400-500 millidarcy permeability, 35°API and with a gas-oil ratio (GOR) of 2,000 to 2,300 cf/bbl.
Within the Lower Campanian interval, the well encountered 32 m (105 ft) of net oil pay, 60-80 millidarcy permeability, 37°API, and a GOR of 2,500 to 2,800 cf/bbl.
APA said appraisal drilling would be needed to confirm additional resources and to determine optimal development well locations.
In addition, the exploration well penetrated another lower GOR interval in the Upper Campanian, but not in a location suitable for flow testing. This shallower zone will require a flow test from a more optimal location.
“The results from the Krabdagu flow test in the two lower intervals are in line with our expectations and provide data that accelerates our understanding of the field and will shape future activity,” said John J. Christmann IV, APA’s CEO and president. “The connected resource demonstrated from the flow tests at Krabdagu combined with the results from Sapakara South are a significant step forward in advancing a project in this area of Block 58.”
At present Maersk Valiant is drilling the Dikkop exploration well in the central portion of Block 58, with further exploration and appraisal activities likely to follow in this region.
