Reservoir Characterization Project: Basin-Centered Gas Accumulation

BCGA - Characteristics WATER Conventional structural gas accumulation Shale Oil Tight Oil Tight Gas Shale Gas Oil Shale Bituminous Sand/Heavy Oil Conventional structural oil accumulation Coalbed gas or Conventional stratigraphic oil accumulation Shallow Biogenic Methane Conventional stratigraphic gas accumulation WATER Tight Oil Shale Gas -0.6% Ro Tight Oil Oil Generation Window 1.3% Ro Tight Gas Gas Generation Window Tight Gas Overpressured Cell (Modified from Sonnenberg, 2017) Tens of miles RCP In pursuit of new ideas Low-permo-porosity Permo-porosity enhanced by natural fractures High pressure The top seal crosses the stratigraphic layers Lack of down-dip water contact High gas saturation (Sonnenberg 2017 and Camp 6 2008)
