Single-Diameter Technology Capable of Increasing Extended-Reach Drilling by 50%


The potential coupling of two leading-edge technologies has garnered much attention for its substantial business case regarding field development optimization. This specific application consists of marrying single-diameter technology and extended reach drilling (ERD). Using these two technologies as companion pieces in a drilling design can positively impact capital cost structure, resulting in economically superior alternative development scenarios. Single-diameter technology, a natural derivative of the conventional solid expandable tubular system, provides the foundation for a significant increase in the lateral reach of many extended-reach wellbores. This extended lateral reach results in increased reservoir contact that can lead to increased production per well. Increased lateral reach and production per well can ultimately reduce the required field well counts and infrastructure, resulting in improved field development economics. This paper will describe how combining these technologies mitigates critical factors that limit achievable reach including dogleg severity, casing openhole size vs. drillstring size, and ultimately torque and drag. Using solid expandable tubular single-diameter technology with significant friction reduction could extend the current ERD envelope 25 to 100%. More efficient reserves access, economic benefits and technical advantages will also be presented. In conclusion, this paper will discuss the technology’s proven, simulated and engineered potential and how it can put more reserves within reach.
