Abstract: Most of the wells in the oilfield Turija are operating with sucker rod pumps, where casing pressure at around 15 bar, and with marginal production rates. The high value of casing pressure indicates high pressure on the face of the formation and depends directly on well productivity. In addition, with increasing value of the casing pressure gas column in the annulus is moving the dynamic fluid level near pump intake and more gas is entering the pump, it results in decreasing pump efficiency. Reduced pump efficiency has a big impact on pump failure resulting in increased lifting costs. The beam gas compressor sucks the gas from the casing and boosts it into the flowline. Backpressure is relieved and allows more hydrocarbons to flow into the well. Based on study, industry known technology is once more proven as a reliable technology for solving casing gas problem and increasing productivity of the oil field.
