In the last two decades the participation of heavy oils in the global volumes of production of oil has been constantly increasing and so the requirement for the development and adjusts of the existing technologies within the different stages of the extraction process of the petroleum.

For the specific case of the production of these oils to achieve the goal of making this flow economically viable up to the Surface is normally the bigger risk with their high viscosity being the main risk. In this way the use of the cyclic injection of steam is the improved and most commonly used method of recovery which increases the temperature of the oil and decreases its viscosity while allows an easier extraction of the resource.

Therefore a research was developed showing how the change of temperature decreases the efficiency of the pump due to the increase of the slippage which in turn is due to drop in the viscosity of the oil and, like in some wells, depending on the permeability of the sand a peak is shown in the efficiency at the beginning of the production because of a momentary pressurization of the well. All this based on slippage formulas developed by different authors, lab tests and field data acquired in the Zone of Moriche, municipality of Puerto Boyacá, where the steam injection is currently used for the extraction of petroleum.

Finally, these data were the start point to develop a new design of pump which adapts to the temperature changes and is more efficient under the conditions of steam injection than the conventional pumps, all this seeking the optimization of the petroleum extraction process in the industry.
