Estudio para la reutilización de los fluidos de perforación en las secciones de 12 ¼ y 8 ½ para los pozos direccionales perforados del campo Tiputini.

Abstract

The following study aims to analyze the reuse of drilling fluids in the 12 ¼ "and 8 ½" sections for the directional wells drilled in the Tiputini field and to establish the best technical and economical reuse proposal for this purpose. Performed laboratory tests on the drilling fluid in two parts, the first to a fluid prepared in the laboratory and the second to a fluid prepared in the field; these tests were carried out during seven consecutive days to visualize the degradation that their properties suffer in the time. The results of the tests indicate that the most relevant degradation of the stored fluid is in the yield point, viscosity, and filtration properties; Mainly due to the chemical degradation of the polymers contained in the fluid as a consequence of the content of reactive solids and bacteria that accumulates in the drilling process; Which is evaluated through the value of MBT. Finally, with the results of the tests carried out, the best proposal is proposed for the reuse of the fluid, which is to reuse the fluid in the same section and in the largest possible volume.
