Phoenix Global Resources starts western Vaca Muerta production

Phoenix Global Resources (PGR) started Vaca Muerta formation production in Confluencia Norte block in Rio Negro, Argentina.

The company completed its first pad of three unconventional wells, which began production in mid-October. The development confirms the presence of the Vaca Muerta formation at the westernmost edge of the block, said partner GeoPark Ltd. in a release Nov. 12.

The pad includes a vertical pilot well, drilled specifically for data acquisition, along with three horizontal wells reaching a total measured depth of 6,300 m, with 3,000 m of lateral extension. 

A high intensity fracturing program was executed across 135 stages, resulting in a current gross production rate of 4,000 bo/d during the ongoing flowback and well testing phase, with production currently being transported to and marketed through Mata Mora Norte block infrastructure. 

The wells are expected to reach their peak production within 90 days of the production start.

As part of its exploration commitment in Confluencia Norte and Sur blocks, PGR has completed the acquisition of 228 sq km of 3D seismic data, which is currently undergoing interpretation. The data is expected to help define the upcoming drilling program, which includes a further four wells that PGR will drill as part of its commitment. 

In May 2024, GeoPark signed a deal with PGR, a subsidiary of Mercuria Energy Trading, to acquire non-operated working interest in four adjacent unconventional blocks in the oil window of the Vaca Muerta formation. GeoPark now holds 50% interest in Confluencia Norte block and 45% interest in Mata Mora Norte block (OGJ Online, May 13, 2024).
