Oil moves through shale rocks, even though the physical structure of such rocks suggests it should not. That is only one of the confusing aspects of how best to exploit the shale oil plays, according to a rock mechanics expert.

Geosteering requires sophisticated technologies, mounds of data — and co-operation. Yet the teams tasked with drilling unconventional wells are often judged on conflicting performance metrics. However, mutual understanding can help geosteering teams overcome drilling challenges to deliver successful horizontal wells.
