On 5 March 2020, Frontera Energy Corp indicated that the Contrapunteo 1 outpost well on CPE 6 Block in the Llanos Basin found oil and that it has been completed.  The Contrapunteo 1 outpost well spudded on 13 November 2019 and it reached a total vertical depth (TVD) of 3,038 ft (926 m) presumably in December 2019. The well was targeting the âC7â Oligocene sandstones of the Carbonera Formation, and it is the second appraisal well drilled to delineate the Coplero 1 discovery. The first one was the Galope 1 outpost well.  The 2,399.85 sq km CPE 6 Block is owned and operated by Frontera with 50% working interest and Repsol with the remaining interest. The block was officially awarded in September 2011 to operator Meta Petroleum Ltd with 50% working interest and partner Talisman Oil & Gas Ltd with the remaining interest. In May 2015, Repsol acquired Talisman and therefore became partner in the CPE 6 Block, and in December 2017 Meta Petroleum changed its name to Frontera Energy.  Background Information  The CPE 6 Block is located along the heavy oil trend, about 70 km southwest of the Rubiales/Quifa Fields. The block has relatively good 2D seismic coverage and 3D only to the northern part where the Hamaca field and Coplero discovery are located.   The Hamaca field was discovered by the Manacacias 1 new-field wildcat (NFW) spudded on 19 April 1989 and completed on 10 May 1989. The NFW reached a total depth (TD) of 3,925 ft (1,196 m) and the main target were the Oligocene sandstones of the Carbonera Formation. The Hamaca field is online since December 2013 and as of end of 2019 it has produced 2.3 MMbo.  In August 2019 Frontera confirmed oil in the Coplero 1 NFW well on the CPE 6 Block, about 6 km southeast of the Hamaca field. The NFW spudded on 27 July 2019 and on 30 July 2019, it reached a TD of 3,150 ft (960 m). The Coplero 1 encountered 8 ft (2.4 m) oil pay in the Oligocene sandstones of the âC7â Member of the Carbonera Formation where logging revealed a clean sand system with 32% porosity.  On 27 September 2019, Frontera spudded the Galope 1 outpost, on the CPE 6 Block, to evaluate the Coplero discovery. The well reached a TD of 8,126 ft (2,477 m) and encountered 10.5 ft (3.2 m) of net oil pay in the Oligocene sandstones of the âC7Bâ Member of the Carbonera Formation. The well is assumed to have been completed and tested in December 2019.
