Elaboración y evaluación de un tratamiento mejorador de movilidad para crudos pesados en operaciones de estimulación química.

Abstract

In the deposits you can find different types of oil; Depending on their API gravity, they are classified as: light crude, medium crude, heavy crude and extra heavy crude. Heavy and extra-heavy crudes are of great importance in the world economy because 70% of the oil corresponds to them, and their production is much more complex, as they require additional treatments, which makes the use of alternative technologies fundamental and important. For the profitable production of said oil. Surfactants are chemical substances widely used in the oil industry in different fields such as drilling, cementing, and fracturing in matrix stimulations. In the latter they are very important due to their ability to decrease the interfacial tension, improve mobility between the crude / water formation and alter the wettability of the rock. The efficiency of a matrix stimulation treatment depends on the proper formulation of the products to be injected into the formation or well, depending on the type of damage. This project presents the process of preparation and evaluation of a product that will be used by the company Guacamaya Oil Services S.A.S., in matrix stimulation treatments. The products used in stimulation treatments must be selected by numerous laboratory tests to verify their behavior and ensure that no adverse effects occur when being injected into the formation or the well. Generally, the formulation of the treatments is carried out through trial and error tests due to the complex composition of the oil. The laboratory tests in the project are divided into three parts: initial characterization of the work crudes, compatibility of the mobility and solvent agents in different ratios until obtaining the desired products and tests of the final products with the oil to be treated. In the initial stage of characterization of the crude, tests are carried out such as determination of API gravity, BSW, asphaltene quantity, oliensis and viscosity, tests recommended by the American Society for Testing and Materials, this in order to know the properties of the raw materials on which the final products will later be tested. Once the crude are characterized, XX
