Course Content

There are numerous reasons to promote Cased Hole Formation Evaluation in unconventional reservoirs. Basic cased hole measurements have been offered as commercial measurements for over 50 years but their applications have primarily been reservoir monitoring or as a contingency in cases where openhole logs could not be run. This talk will suggest that CHFE be utilized as an alternative to standard openhole formation evaluation logging to alleviate the risks traditionally associated with openhole logging in horizontal wellbores. This information can then be used to scientifically design a more efficient completion.

Speaker

icon James Hemingway joined Schlumberger in 1979 and has held various petrophysical and engineering positions for most of that time. He has been heavily involved in evaluating unconventional reservoirs using electromagnetic and nuclear measurements. James holds degrees in chemistry and chemical engineering.

He worked on various Enhanced Oil Recovery projects in California for 8 years where he developed techniques for reservoir evaluation using high frequency electromagnetic propagation as well cased hole techniques primarily based on pulsed neutron measurements. James later moved into an engineering role working of various pulsed neutron projects. While working in Paris a few years later he launched an initiative to be called Formation Evaluation Behind Casing (CHFE) with added measurements that did not need to be combined with openhole measurements for completion design.

His primary objective for the past 25 years has been to develop viable techniques for formation evaluation behind casing. Seeing the increasing number of wells that do not have openhole formation evaluation measurements has led to a culture of well planning that does not include openhole logging for formation evaluation. After experimenting with various inelastic ratio measurements and gamma-gamma density measurements to fill in the missing pieces for a reasonably comprehensive formation evaluation behind casing a new measurement was added to the industries capabilities. These capabilities allow the industry to properly evaluate unconventional wells in environments where openhole logging is considered too expensive and risky.

James was a Distinguished Lecturer for the Society of Petrophysicists and Well Log Analysts in 2000-2001 and 2011-2012 on cased hole logging technologies. And a Distinguished Lecturer for the SPE in 2014-2015. James retired in December 2016. In 2018 he assumed the role of Vice President Technology for the Society of Petrophysicists and Well Log Analysts (SPWLA) and currently serves as president of the SPWLA.
