  • What’s new in well logging and formation evaluation

    Stephen Prensky

    The drilling of horizontal wells has been increasing dramatically, due in great measure to the strong interest in unconventional reservoirs where these wells are critical to development economics. Consequently, many of the recent advancements in wireline and logging-while-drilling (LWD) technology covered in this article are designed to assist in the placement (geosteering), completion (cement integrity and fracture treatment), and production optimization (well intervention) of horizontal wells. The continued consolidation in 2010 of logging and petrophysical service providers means that these innovations are increasingly being provided by a few large companies.
