On 5 May 2020, Hocol Petroleum, a 100% subsidiary of Ecopetrol, announced that the Bullerengue 3 shallower-pool wildcat (SPW) discovered gas in several sand intervals in a shallower reservoir than the Bullerengue 1 discovery, which produces from Eocene sandstones of the Chengue Formation. It is speculated that the Bullerengue 3 discovered gas in the Miocene-Oligocene sandstones of the Cienaga de Oro Formation. The company indicated that they are doing several production tests since 17 November 2019.  The Bullerengue 3 SPW lies in the SSJN 1 Block in the Atlantico Department in the Lower Magdalena Basin. The 920.11 sq km SSJN 1 Block is owned and operated by Lewis Energy with 50% working interest, and non-operating partner Hocol with the remaining 50% working interest since December 2009 when Hocol farmed in. The original 1,672.7 sq km SSJN 1 Block was officially awarded to Lewis Energy in December 2008, and in July 2019, 752.28 sq km were relinquished.  Background Information  The Bullerengue gas/condensate field was discovered in October 2015 by the Bullerengue 1 new-field wildcat (NFW). The NFW was drilled to a TD of 2,286 m (7,500 ft) where it tested 2.5 MMcfg/d and 50 barrels of condensate in an unreported reservoir. Five other wells have been drilled in the structure: Bullerengue Sur 1 to 4 and Bullerengue SW 1. The Bullerengue Sur 1 exploratory well found 25 m (80 ft) of Eocene Age gas pay over several horizons, Ecopetrol SA announced on 27 December 2019. The field started production in October 2015.  In December 2019, Ecopetrol SA announced that Hocol Petroleum Ltd, their 100% owned subsidiary, and Lewis Energy Colombia are evaluating the Lewis Energy-operated Bullerengue SW-1 outpost well on contract block SSJN 1 in the Lower Magdalena Basin. The Bullerengue SW-1 outpost spudded in July 2019 and is located about 3 km southwest of the Bullerengue 1 gas/condensate discovery well.
Bullerengue 3 expl. (Lewis Energy 50 % op, Hocol 50%) in SSJN1 block, in Caribbean, reportedly gas find in prospect shallower than the 2015 Bullerengue-1 discovery now on stream, several intvs encountered, no details.
