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 have non-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.
