After adding its third new oil field this year, GeoPark Ltd. plans to drill seven wells on the Llanos 34 block during this year’s third quarter to further delineate southern Jacana and northern Tigana oil fields.
The operator completed the Curucucu 1 exploration well on a new fault trend east of the Tigana-Jacana fault trend on Llanos 34 block in Colombia (OGJ Online, Oct. 14, 2016). The well was drilled to a total depth of 14,600 ft. An electric submersible pump tested the Guadalupe formation at a production rate of 1,700 bo/d through a 100/64-in. choke. The 15.8° gravity oil maintained 70 psi wellhead pressure with a 0.4% water cut. Geopark said additional production history is required to determine stabilized flow rates, but petrophysical log analysis indicated potentially productive hydrocarbons in the shallower Mirador formation.
The operator drilled Curucucu 1 from an existing well pad in the recently discovered Jacamar oil field. The well’s 9,000-ft lateral extension set a horizontal record for Llanos 34 block. Curucucu is adjacent to Jacamar field and marks the eleventh oil field discovered on Llanos 34 block, since Geopark’s 2012 acquisition. The operator has discovered 13 oil fields in Colombia.
Geopark is operator of Llanos 34 with 45% working interest.
