We’ve recently learned that horizontal velocity changes may have significant implications to well productivity, and these horizontal variations are generally attributed to geomechanical stress changes in rock fabric.
In this case study – targeting the Spirit River, Wilrich and Falher F formations – we’re examining three wells that are drilled with similar completion methods, but the orientation of each well and the resulting production is very different.
This allows us to highlight the relationship between drilling direction in relation to the local azimuthal stress vectors with production.
Eric Keyser is an exploration geophysicist, part of the team that recommended the 11-22 Blackstone well that established the cumulative gas record for Alberta (336 BCF). He has extensive domestic and international interpretation experience in Canada (Deep Basin, Foothills, Beaufort, Mackenzie Delta, NWT, Grand Banks, Scotian Shelf), United States (Gulf Coast, Rocky Mountains, Offshore California, Alaska), Venezuela, Ecuador, Peru, Chile, Brazil, Bolivia, Australia, New Zealand, United Kingdom, Gabon, Congo, Angola, Tunisia, Algeria and the South China Sea.
