APA Corporation has announced an oil discovery offshore Suriname at Baja-1 in Block 53 and provided an update on recent drilling operations at Dikkop-1 in Block 58.
Baja-1 was drilled to a depth of 5,290 metres and encountered 34 metres of net oil pay in a single interval within the Campanian. Preliminary fluid and log analysis indicates light oil with a gas-oil ratio (GOR) of 1,600 to 2,200 standard cubic feet per barrel, in good quality reservoir. The discovery at Baja-1 is a down-dip lobe of the same depositional system as the Krabdagu discovery, 11.5 kilometres to the west in Block 58. Evaluation of open-hole well logs, cores and reservoir fluids is ongoing.
“Our success at Baja marks the sixth oil discovery we have participated in offshore Suriname, and the first on Block 53,” says John J. Christmann, APA CEO and president. “This result confirms our geologic model for the Campanian in the area and helps to de-risk other prospects in the southern portion of both Blocks 53 and 58.”
APA recently received regulatory approval regarding an amendment to the Block 53 Production Sharing Contract (PSC), which provides options to extend the exploration period of the PSC by up to 4 years. The company is currently progressing the formalisation of the election of the first 1-year extension, for which all work commitments are complete.
APA is operator and holds a 45% working interest in Block 53, with Petronas holding a 30% working interest and CEPSA holding a 25% working interest. Baja-1 was drilled using the Noble Gerry de Souza in water depths of approximately 1,140 metres. The drillship will mobilise to Block 58 following the completion of current operations, where it will drill the Awari exploration prospect, approximately 27 kilometres (north) of the Maka Central discovery.
APA also announced that operations have concluded on the Dikkop exploration well in Block 58. The well encountered water-bearing sandstones in the targeted interval and has been plugged and abandoned. TotalEnergies is the operator with a 50% working interest, and APA holds the remaining 50% working interest. The drillship Maersk Valiant will be moving to the Sapakara field to drill a second appraisal well at Sapakara South, where the joint venture conducted a successful flow test late last year.
