| Description/Abstract | The Colombian Oil Co. (Ecopetrol) was the former Tropical Oil Co. that ended its activities in Colombia after a decision of the government to obtain all the oil concessions. The Tropical Oil Co. operated primarily in the De Mares Field. This company used 3 well completion systems: slotted liner, combined string, and casing. The latter currently is in use to control sand inlet using a cluster shot. Ecopetrol uses gravel and/or coconut shells to pack the grooved tubing. Well stimulation has been done with several systems, including hydraulic fracturing, block buster, carbon dioxide treatment, hydrochloric acid treatment, varsol treatment, and coconut shells packing. Production systems currently used include mechanical pumping, centrifugal pumping, and hydraulic pumping. Ecopetrol has made an investigation to evaluate which system is the most convenient from the aspect of economic feasibility, considering production ranges and costs. |
