A subsidiary of CruzSur Energy Corp., Vancouver, BC, wants to test an old well near a recent technical discovery on the Maria Conchita block in the Department of La Guajira, Colombia.
The subsidiary, MKMS Enerji Sucursal Colombia, is seeking modification to an environmental license that would allow it to test the Aruchara-1 well drilled by Texaco in 1980. MKMS operates the 60,076-acre block.
Test results would supplement information from its technical discovery, Istanbul-1, drilled while CruzSur’s name was PentaNova Energy Corp. (OGJ Online, Apr. 6, 2018).
The Istanbul-1, Aruchara-1, and Tinka-1, drilled by Ecopetrol in 1988, all have tested natural gas from Miocene strata on the block.
MKMS has submitted an evaluation program to be completed within 1 year, which can be extended by a year with the drilling of a commitment well.
CruzSur said its subsidiary is studying options for reentering Istanbul-1 to test zones that appear to be gas-bearing but were not part of the original test.
MKMS has notified the National Hydrocarbons Agency that it will not proceed with a third exploration phase, although it might do so after the evaluation program. It has relinquished about 46% of the acreage not covered by the evaluation program.
