Descripción
El objetivo de este trabajo es evaluar técnicamente dos nuevas tecnologías (ensanchadores y centralizadores Protech CRB) implementadas por la compañía equión energía Limitada para reducir tiempos de viajes y tiempos de corridas de revestimientos durante la perforación de pozos en el Piedemonte Llanero Colombiano.
Para lograr lo anterior, se reunió y limpió la información necesaria de los reportes diarios de perforación de ocho pozos de correlación (offset) seleccionados y se comparó con la de los dos pozos donde se implementaron las tecnologías. Datos de tiempos y velocidades de viajes y corridas de revestimientos, tasas de penetración (ROP) y tiempos planos (fl at times) fueron analizados y posteriormente cuantificados, para determinar el impacto operacional y económico de los ensanchamientos de hueco y las corridas con centralizadores Protech CRB.
En los resultados obtenidos, se observan los beneficios alcanzados con la implementación de las nuevas tecnologías y su rentabilidad. se destaca su aporte a las buenas condiciones del pozo, que reducen riesgos comunes de presentar tiempos no productivos (nPt) durante las actividades de perforación, relacionados con eventos de pega de tubería, pérdida de integridad del revestimiento y trabajos remediales de cementación, y los costos adicionales que pueden generar.
The aim of this project is the technical evaluation of two new technologies (hole enlargers and Protech CRB centralizers) implemented by the company equion energia Limited to reduce pipe tripping and casing/liner running times during the drilling of wells at Colombian Piedemonte Llanero oilfi elds. In order to accomplish this goal, information contained in daily drilling reports from eight different offset wells was gathered and compared to the one from the two wells were technologies were applied. Data of time summaries, pipe tripping and casing/liner run velocities, as well as rates of penetration (ROP) and flat times were analyzed and therefore quantified to determine the operational and economic impact of hole enlargements and Protech CRB centralizers performance. Finally, this project results clearly show the advantages reached with the implementation of the new technologies and its profit.It is important to highlight their contribution to improve hole conditions, which reduce common risks that could lead to havenon-productive times (NPT) during drilling operations. For example, stuck pipe events, casing integrity failure and remedial cementing jobs, along with the additional costs they may generate.
