GeoPark Ltd. announced the startup of production at the Confluencia Norte Block in Rio Negro, Argentina, on Nov. 12.

GeoPark holds a 50% working interest in the block and operator Phoenix Global Resources (PGR) holds the remaining 50%.

The Confluencia Norte Block recently completed its first pad of three unconventional wells, which began production in mid-October. The pad includes a vertical pilot well and three horizontal wells reaching a total measured depth of 6,300 m. Gross production has reached 4,000 bbl/d, with production being transported to the Mata Mora Norte Block facility. The wells are expected to reach peak production within 90 days.

“The start of production at the Confluencia Norte Block in Rio Negro Province is a significant milestone, marking our first major exploration achievement in Vaca Muerta and validating the immense potential that underpinned our entry into this world-class basin,” GeoPark CEO Andrés Ocampo said in a press release.

As part of its exploration commitment in the Confluencia Norte and Sur blocks, PGR has completed the acquisition of 228 sq km of 3D seismic data, which is currently undergoing interpretation. PGR and GeoPark are working closely to expand the exploration and development of these assets.
