Increasing Production with Better Well Placement in
Unconventional Shale Reservoirs - Challenges and Solutions

Abstract:
The idea that the stimulation process "will take care of the geology" in unconventional reservoirs is proving false.
Unconventional reservoirs are often regarded as resource plays with little demand for reservoir analysis beyond simple geosteering techniques during the development campaign. This leads to the common practice of stimulating wells with equally spaced stages and treating all the stages exactly the same, with no regard to the nature of the rock being treated. As a result, production can vary from each stage, with some stages either not contributing or doing poorly.
Clearly, the stimulation process alone cannot mitigate the impact of geology in unconventional reservoirs; however, mechanisms do exist for improving results in these reservoirs. Mapping the distribution of geomechanical properties for optimal stimulation is one example of unconventional thinking that can be applied. The practice of "steering to brittleness" or similar techniques can have a direct impact beyond simple well placement. Given a map of geomechanical properties along the wellbore, completion engineers can optimize the position of plugs or packers, and stimulation engineers can fine tune the design of the treatment applied to the rock. By re-establishing the link between production and geology, these methods can decrease the exploitation costs of unconventional reservoirs.
Biography:
Jason Pitcher is the Director of Greystone North LLC consulting. Previously he was the Director of Consulting Practic at Cameron, based in Houston, Texas. He received his bachelors of Science degree in Geology from the University of Derby and his masters of Science degree in Mineral Exploration from Imperial College in London. Jason has over 24 years of experience in oil and gas assets, having worked in multiple areas of drilling, completion and production solutions delivery. He holds a BS in Geology from the University of Derby and an MS in mineral exploration from Imperial College London. He has developed and managed well placement operations around the world, taught geosteering for international geoscience organisations and works diligently on SPE committees. He has co-authored over 25 papers and articles on LWD tools, petrophysics, geosteering, and in recent years, unconventional reservoir exploration and exploitation.
Jason was an SPE Distinguished Lecturer for the 2012-13 lecture season.
