Proppant transportation in vertical fractures with controlled roughness in different positions

Petroleum Research
Effective proppant placement is essential for increasing the production of unconventional oil/gas reservoirs. It can substantially affect the fracture roughness. This paper presents a laboratory fracture model to quantify the effect of fracture roughness

Feasibility of Proppant Flowback Control by Use of Resin-coated Proppant [PDF]

Proppant flowback is a problem in Xinjiang oilfield. It decreases production rate of a fractured oil well, corrodes surface and downhole facilities and increases production costs.

Proppant Transport in Complex Fracture Networks

, 2018
During hydraulic fracturing, natural fractures and bedding planes can intersect with growing hydraulic fractures and form complex fracture networks. This can result in the flow of fluid and proppant in convoluted fracture pathways with highly variable ...

Characterization of mechanical properties of shale constituent minerals using phase‐identified nanoindentation

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 4, Page 542-558, 4 February 2025.
Abstract Characterization of mechanical properties of shale constituent minerals (viz., the mechanical genes of shale) has been challenging but of great significance for engineering applications in shale formations. In this study, a phase‐identified nanoindentation is proposed to decode the mechanical genes of shale using a large nanomechanical dataset.

Height Propagation Law and Controlling Strategies of Acid Fractures in Carbonate Gas Reservoirs With Bottom Water Layer Under Different Stress Profiles

Geofluids, Volume 2025, Issue 1, 2025.
Acid fracturing is currently employed to develop the carbonate gas reservoir in the second section of the Dengying Formation at the Anyue Gas Field, Sichuan Basin. However, improper acid‐fracturing operational parameters pose a risk of fracture communication with the bottom water layer, leading to increased water production and a significant decline in

NMR‐Based Quantitative Characterization of Water Imbibition in Deep Shale Rocks Under Different Pressures and Temperatures

Geofluids, Volume 2025, Issue 1, 2025.
Unconventional tight/shale gas reservoirs have gained significant attention in the energy sector. The importance of temperature and pressure in shale imbibition lies in their profound influence on the kinetics, rate, and ultimate amount of water uptake, which directly impacts the efficiency of gas production.
