Resumen
Once oil has been extracted from land or marine deposits, it is processed by three recovery techniques (primary, secondary, and tertiary) to eliminate or separate all the desired components from those that are not, such as water and salts. In fact approximately 15% of the well potential is recovered from the primary technique associated with the process of extracting oil via the natural rise of hydrocarbons to the surface of the earth, or using pump jacks mainly. The second includes the injection of gas or water to the well to displace the oil and move it from its resting rock, and the tertiary technique, also called enhanced oil recovery, is used to extract the remaining oil from reservoirs where primary and secondary techniques are no longer cost effective. EOR includes use of thermal, gas chemical hydrodynamics, or combined EOR. This technique includes use of the Gunbarrel tank, which can obtain high efficiency and identify the variables of operation; it is important to model this process considering a distributor as a horizontal tube located at the bottom of this tank where the oil flows through small holes. The improvement of the hydraulic design of the distributor in a separator tank using computational fluid dynamics, reporting six cases, was carried out in this work. The results show a preliminary model design of this internal distributor that improves when used with 10 holes starting with a diameter of 6 × 10−4 m for the first hole increasing each one by 6 × 10−5 m.
