Drilling in the Appalachian Basin in Pennsylvania has evolved since its inception. Operators have shifted their focus from mere wellbore delivery to delivering wells in the shortest amount of time to reduce risks and costs and drive efficiency. The complete paper presents a case study in which offline cementing improved operational efficiency by reducing drilling times and provided significant cost savings.
Introduction
For decades, the focus during drilling operations has been on achieving faster rate of penetration (ROP) and drilling time to reduce well costs. However, the significance of ROP improvement accounts for less than 25% of the full well-construction cycle.
