“…The orientation can also vary from being perpendicular to the direction of the well to following the direction of the well. The EPV is considered an ellipsoidal volume, a geometric characteristic indicated in [15,[17][18][19][20][21][22][23][24][25]. Other geometries are not considered.…”

“…These processes are called hydrofracturing [13,14]. According to microseismic imaging a shale gas formation subject to hydraulic fracturing develops damage zones or fracture volumes, Effective Propped Volume (EPV), with a fundamentally ellipsoidal geometry [15][16][17][18][19][20][21][22][23][24][25]. Furthermore, externally to this ellipsoidal zone, a fracturing zone called Stimulated Recovery Volume (SRV) is produced, generally represented by a prism in the technical and scientific literature [26][27][28].…”

We analyze the effect that the geometry of the Effective Propped Volume (EPV) has on the economic performance of hydrofractured multistage shale gas wells. We study the sensitivity of gas production to the EPV’s geometry and we compare it with the sensitivity to other parameters whose relevance in the production of shale gas is well known: porosity, kerogen content and permeability induced in the Stimulated Recovery Volume (SRV). To understand these sensitivities, we develop a high-fidelity 3D numerical model of shale gas flow that allows determining both the Estimated Ultimate Recovery (EUR) of gas as well as analyzing the decline curves of gas production (DCA). We find that the geometry of the EPV plays an important role in the economic performance and gas production of shale wells. The relative contribution of EPV geometry is comparable to that of induced permeability of the SRV or formation porosity. Our results may lead to interesting technological developments in the oild and gas industry that improve economic efficiency in shale gas production.
