Subsurface complexities related to the formation of Peripheral Foreland Basins (PFBs) can have significant impacts on unconventional resource development within their respective basin. In the Arkoma Basin of Southeast Oklahoma, a PFB formed during the Marathon Orogeny, the onset of thrusting and tectonic loading induced a complex series of dip-slip and strike-slip faults during basin formation.

Existing interpretation of these subsurface hazards are thought to have substantial effect on rock quality, water intrusion, and parent-child interactions during development (among others).

Foundation Energy Management (FEM) employed a series of technologies to increase their understanding of the reservoir and its hazards. These technologies include geochemical liquids analysis from wellbore cuttings via Rock Volatiles Stratigraphy (RVStrat), passive acoustic imaging sensors (known as Measuring while Fracing or MWF), and precision injection of proppant, water, and gas tracers during the stimulation treatment. These technologies were applied to a pair of infill development wells in an existing unit. The goals of the project were meant to increase understanding of the following parameters: reservoir characterization, landing zone selection, completion optimization, fracture-driven interactions (FDIs), and subsurface hazards.

The multi-disciplinary study successfully met the objectives/goals of the Operator. The technologies employed assisted with quantifying and answering a series of questions related to the reservoir, its subsurface hazards, and provided economic implications into future development plans and strategy.
