Texas Petroleum Co.'s Mata field is an 84,453-acre concession separated into 3 blocks that contain a total of 463 reservoirs. It is one of E. Venezuela's major fields and currently produces an average of 22,500 bpd. Production is highly diversified, i.e., natural flow, gas lift, hydraulic pump, and rod pumping. Crude gravities range from 10/sup 0/ to 50/sup 0/ API, so production is divided into 2 streams: the Mata Mesa 30/sup 0/ API and Mata Merey 17/sup 0/ to 22/sup 0/ API. At present, 78% of the production is from secondary recovery projects. The first application of secondary recovery was initiated in 1957 with a gas injection project. There are 18 gas injection projects now in operation, producing 44% of the total field production. Waterflooding, initiated in 1969 with a pilot project in a 2-well reservoir, proved highly successful, and consequently, has been extended to 19 reservoirs producing 34% of the current field production. Other subjects discussed include geology, rock properties, fluid characteristics, production history, well completion, artificial lift methods, stimulation treatments, gas injection, and waterfloods.
