Análisis técnico de los problemas operacionales durante la perforación de pozos direccionales del campo Shushufindi

Abstract

This paper presents the most relevant aspects of the Shushufindi field, the largest in the Eastern Ecuador Basin, location, lithology, stratigraphy, production and pressure reviews and other important points to have a clear and detailed characterization of the field. It is also mentioned in a theoretical way concise information of all aspects referring to directional drilling, concepts, equipment, techniques, tools and operational problems that can arise in a drilling job. For the analysis of the problems themselves, we start by describing in a general way and by perforated section the standard design of a directional well, (generalized design model for the drilling of a shushufindi field well), such as: drills, BHA's, drilling fluids, drilling parameters required, types of casing lowered, cementing carried out and the operational sequence, ending with the study of each well and a matrix of the main operational problems found in the drilling. Finally each problem is shown per section and the event is detailed adding the contribution of a solution proposal for each problem and a description is made about the new technical solutions that can be implemented to reduce the operational risks and the drilling time of each perforated section.
