Drilling: Optimizing Extended Reach, Horizontal, and High DLS Operations for Better ProductivityWith the rising demand for oil and gas, the industry is continually seeking ways to optimize production rates by exploring new drilling techniques and technologies. Extended reach, horizontal, and high DLS (dogleg severity) drilling are some of the most common techniques used in unconventional and challenging wells.High DLS wells can pose significant challenges to drilling operations due to their complex geometries and low tolerances for error. As a result, drilling engineers must employ advanced drilling equipment and techniques tailored to overcome the challenges.One of the most critical aspects of high DLS drilling is the drill bit. High pressure drilling bits can penetrate even the hardest formations and reduce drilling time. They can handle extreme conditions, high-temperature gradients, high angle drilling, and lateral displacement, making them ideal for unconventional well schemes.In addition to high DLS wells, extended reach and horizontal drilling also require specific attention and meticulous planning. Extended-reach drilling techniques can reach distances up to 40,000 feet and require precise directional control and an appropriate drilling program tailored to the formation.Horizontal drilling is a technique that involves deviating the wellbore from vertical to horizontal, thereby increasing the amount of oil or gas exposed to the wellbore. It offers several benefits, such as improved reservoir performance, reduced surface footprint, and minimized environmental impact.To optimize extended reach, horizontal, and high DLS drilling operations, significant investments in advanced drilling technologies are necessary. Logging-While-Drilling (LWD) and Measurement-While-Drilling (MWD) tools present a value-added solution to these challenges by providing real-time data that informs operators on downhole conditions.LWD and MWD tools can also be used to obtain vital information about the rock formation through gamma ray, resistivity, and sonic logging. These tools enhance drilling accuracy, provide geosteering, and enable drilling curves that match the targeted reservoirs.The use of pad drilling techniques can also boost optimization efforts by minimizing rig moves, reducing non-productive time, and enhancing efficiency. Pad drilling techniques involve drilling multiple wells from a single pad, eliminating the need to move rigs between wells, leading to cost savings and reduced environmental impact.In conclusion, optimizing extended reach, horizontal, and high DLS drilling operations is essential to ensure improved productivity and better well placement in complicated unconventional oil and gas well schemes. The use of advanced drilling technologies such as high pressure drilling bits, LWD/MWD tools, and pad drilling techniques can optimize drilling operations and improve the industry's overall performance.
