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.

Revised Drilling Practices Lead to Lateral-Length Gains in Marcellus Shale
A drilling team has focused on increasing lateral lengths in the Marcellus Shale. The team determined which operational practices would need to be revised in order to drill and case laterals in excess of 18,000 ft.
Thailand Joint-Development Project Delivers MWD/LWD Benefits
A joint-development project has delivered a high-temperature measurement-while-drilling/logging-while-drilling (MWD/LWD) suite rated for 200°C. Results to date are compared with previous performance in the Gulf of Thailand (GoT).
Drilling: What Can We Do To Thrive?
Falling oil prices are the acid test of drilling efficiency. SPE Technical Director Jeff Moss of ExxonMobil talks about ways to build in lasting savings as part of this special report.
