摘要

In western Venezuela, accesing low-pressure, depletedreservoirs is a challenge that has to be overcome in orderto recover high volumes of remnant hydrocarbons, in thearea of Lake Maracaibo (Lagomar, Tía Juana andLagunillas fields, among others). In these fields, theutilization of conventional fluids becomes technicallydifficult and low profitable, because the hydrostaticpressure exerted by the fluid column is higher thanreservoir pressure, causing fluid losses and formationdamage, with the following consequences: increase in thecost of workover operations, potential fracturing of theformation, formation damage, delayed production and finally, complete loss of the well. The technology ofaerated O/W emulsion for workover operations, is analternative to solve these problems. The successfulapplication of this technology begins with an adequateselection of the wells and a proper design of theformulation.This work covers the development, technical featuresand application of the technology of aerated emulsionutilizing static mixers that allowed to homogenize atriphasic system (air, oil and water) into one phase. Thistechnology also allowed to restore the originalmechanical conditions of the well that other conventionalsystems failed to accomplish. As a consequence, expected
