Production of natural gas from tight sandstone reservoirs is a complex interplay of flow from rock matrix to natural fractures, flow within complex networks of natural fractures, and flow within different complex networks of hydraulic fractures.
In cases of such high complexity, no single technology or scientific discipline can alone tell the story. Instead, only an integrated workflow combining the clues from the various disciplines: seismic, rock mechanics, petrophysics, geology, and production, can stand a chance of realistically capturing the complexity of flow in fractured tight gas systems. The Mamm Creek field project includes all of these disciplines with goals ranging from theory, through lab experiments to practical oil and gas field applications.

04:20 – 05:00 Discussion – focused on these themes:
- What are the big unknowns in tight gas exploration and production, and how do we address those from the perspectives of each discipline?
- How can the proposed in-situ lab help narrow the uncertainties?
- Hydraulic fracturing is very controversial – is this because of an ill-informed public or the wrong technology?
