Three flare gas measurement campaigns sponsored by Climate and Clean Air Coalition (CCAC) were conducted in Colombia during the periods of 10 to 14 July 2017, and 8 to 12 July and 15 to 19 July 2019, respectively. Eight flaring oil and gas production facilities (Sites 1 to 8) were surveyed during these campaigns. Each site was nominated by its operator for inclusion in the study based on an objective screening process. A site was selected either because it was known to have large flaring rates, or because it was deemed representative of highly replicable flaring reduction opportunities.
The results have been processed to evaluate potential high-impact opportunities to cost effectively reduce flaring and associated black carbon (BC) emissions. A prefeasibility assessment of the practical mitigation options applicable to each flaring reduction opportunity was performed to determine the optimum mitigation solution. At least two of these opportunities have been advanced to the to the refined business case level for consideration by the operator and potential financiers.
A separate report is provided for each site to provide a standalone assessment of its flaring reduction opportunity and to allow easy promotion of the opportunity. This report presents the results for Site 4 operated by Operator 1. This site features a satellite oil battery, which receives production from two oil wells located onsite. Effluent from the two wells is separated into water, oil and associated gas for production accounting metering. Subsequently, the oil and water are recombined and pumped into a flow-line for transport to a central treating facility. The associated gas production in excess of onsite fuel needs is flared. There is no nearby gas gathering system (GGS) and the closest oil treat facility is located 17 km away.
Both an anonymized and unanonymized version of this report has been prepared in both English and Spanish. The anonymized version is for presentation to the CCAC and the unanonymized version is for presentation to the operator.
