The drilling industry has undergone a revolution in the past decade, with horizontal drilling becoming the norm for the development of many unconventional and conventional reservoirs. Horizontal wells pose unique challenges for log interpretation and formation evaluation. Most of the logging technology in use was developed for evaluating vertical wells.

The measurement responses observed in horizontal wells are often different from vertical wells in the same reservoir. It is important to understand how standard logging “quad-combo” measurements are affected by the orientation change from vertical to horizontal. Sometimes these changes are misinterpreted or assumed to be tool malfunctions. By understanding the changes in the measurement responses, we can take full advantage of the information they provide to understand the formations surrounding the borehole. This talk will address some of these issues and discuss the various applications for real-time LWD measurement to improv drilling efficiency and safety.

Michael Gillen is the global director for formation evaluation services at Baker Hughes. With 34 years of logging and formation evaluation experience, Gillen began his career as a field engineer with Dresser Atlas in 1981. He later joined Numar, where modern nuclear magnetic resonance technology was first developed for well logging. Joining Baker Hughes in 2000, Gillen was responsible for introducing several new wireline technologies before moving to the Drilling Services group to lead the LWD team. He holds a BS degree in engineering from the University of Colorado and an MBA degree from Pennsylvania State University. Gillen has published several papers on new wireline and LWD technologies and interpretation techniques and holds two patents in the field.
