UFM‐Based Simulation of Competitive Multi‐Fracture Propagation in Horizontal Wells

open access: yesEnergy Science &Engineering, EarlyView.
Simulation schematic of Competitive Multi‐Fracture Propagation in Horizontal Wells. ABSTRACT Multi‐stage hydraulic fracturing in horizontal wells is vital for stimulating unconventional reservoirs, yet uneven fracture propagation often restricts the effective communication volume of the reservoir.

Volume fracturing of deep shale gas horizontal wells

open access: yesNatural Gas Industry B, 2017
Deep shale gas reservoirs buried underground with depth being more than 3500 m are characterized by high in-situ stress, large horizontal stress difference, complex distribution of bedding and natural cracks, and strong rock plasticity.

Numerical Simulations of Hydraulic Fracturing in Carbonate‐Type Hot Dry Rock Reservoirs Based on the Coupled Thermo‐Hydraulic‐Mechanical‐Damage (THMD) Model

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT Hydraulic fracturing technology is widely used in Enhanced Geothermal System (EGS) projects to induce fractures and enhance the permeability of thermal reservoirs. The hydraulic fracturing process of hot dry rock (HDR) is actually a multiphysics coupling process that couples the heat transfer field, seepage field, stress field, and damage ...

A Prior Assessment of Heat Transfer Efficiency From Shale Formations to Hydraulic Fractures in Geothermal Wells Converted From End‐of‐Lifetime Natural Gas Wells

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT Although the conversion of end‐of‐lifetime fractured hydrocarbon wells to geothermal wells has gained a strong momentum in research, it is necessary to perform thorough technical assessments of well conversion before pilot testing. The objective of the study was to perform such an assessment on converting fractured horizontal hydrocarbon wells

An Improved Scheme of Frequency-Dependent AVO Inversion Method and Its Application for Tight Gas Reservoirs

open access: yesGeofluids, 2019
AVO inversion is a seismic exploration methodology used to predict the earth’s elastic parameters and thus rocks and fluid properties. It is built up on elastic theory and does not consider the seismic dispersion in real strata.

Carbon Storage in Fold‐and‐Thrust Belts: An Overlooked Gigatonne Storage Opportunity

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT This study presents numerical investigations of the trapping characteristics of fold‐and‐thrust belt structures, defining three carbon capture and storage (CCS) play types that could be used to store commercial volumes (millions of tonnes) of CO2.
