Drilling Innovation

From the beginning, the name of the game has been innovation. No single word has characterized drilling design and operations more completely during the 160 years since Colonel Drake first probed the Pennsylvania landscape for oil. This fundamental aspect of our business applies now more than ever across geographical and corporate boundaries.

Examples of evolution in well construction during the past several years include new horizontal-well applications, breakthroughs in bit and ­directional-drilling technology, synthetic fluids, fracture-stimulation advancements, managed-pressure drilling, and the digital revolution.

All this being said, few could have imagined the present state of the industry unfolding with the development of unconventional resources. During the past 7 years alone, US oil production has again become a dominant global force, doubling from 5.5 million to more than 11 million B/D. Even greater effects on gas reserves have been realized with the expansion of infrastructure to deliver a rising tide of new gas production to consumers. Around the globe, the ultimate benefits of these current trends remain to be seen as new reserves continue to be identified within most of the world’s oil- and gas-producing regions.

Papers selected for this feature serve as superb examples of drilling evolution in a variety of locations, including US onshore, offshore Thailand, deepwater Gulf of Mexico, Sakhalin Island, and the North Sea. In each case, evolution in well design, equipment, and operational procedures has occurred, resulting in dramatic advancements in technical feasibility, efficiency, and safety. Paper SPE 191783, “Drilling Extended Laterals in the Marcellus Shale,” reveals advancements underpinning new unconventional production in that area as well as in the Permian Basin, the Bakken, the Eagle Ford, and the Utica fields. Successful results published by international and offshore operators in Papers SPE 191054 and OTC 29065 highlight not simply new tools or procedures but also far-reaching breakthroughs that fundamentally alter the outlook and value of these types of assets. Papers referenced in the pages that follow offer but a glimpse into a greater library and wealth of knowledge available to SPE readers desiring to remain connected with drilling innovations.
