Análisis técnico de problemas durante la perforación de pozos direccionales ubicados en el campo sacha

Abstract

With the passage of time, more companies enter the oil business and use directional wells in their drilling programs, generating more efficient and reliable processes. So it is necessary to have basic knowledge in the extensive subject of directional drilling. The present work describes in general the standard design of a modified J-type directional well and the operations to be followed for the drilling of the same. In addition, an analysis of the daily reports of drilling operations of 5 directional wells, located in the Sacha field. It identified the problems that have occurred during the drilling of the study wells, the causes that originated them and the consequences that they represent. It presented technical solutions that can be implemented to reduce the operational risks and the drilling time of each perforated section, representing the results obtained in graphs the depth vs time, with a shorter drilling time when applying the solutions to a well.
