Análisis de Factibilidad para la Aplicación de Liner Drilling en la Perforación de Pozos en los campos Tapi-Tetete Y Yuca

Abstract

Conventional drilling is currently becoming increasingly complicated for drilling engineers and geologists. Because the fields face operational problems related to the incompatibility of well pressures, complex geological structures and temperatures. Causing complications in the construction of the well: collapses in the walls, sticking of drilling tools or fluid losses, producing more non-productive time (NPT) and additional costs. One of the solutions to the problems is the implementation of the Liner Drilling technique, as a means to mitigate operational risks and reduce non-productive time. The study of different technologies allows its use to be suitable for different types of fields, such as Tapi-Tetete and Yuca; In the present investigation real well data was collected in the respective fields that have been drilled conventionally, to perform a technical-economic analysis, implementing the Liner Drilling technique through pipe design calculations, torque and drag simulations, tension, buckling and hydraulic analysis; The costs of each of the operations are evaluated by comparing conventional and non-conventional drilling, determining the economic impact of this innovative technique, in order to evaluate the feasibility of the Liner Drilling technique in the respective study wells.
