Source Analysis and Countermeasure Research of Sand Production after Hydraulic Fracturing in Tight Sandstone Gas Reservoir

Lithosphere, 2022
Sand production is the most common problem after hydraulic fracturing treatment. This problem is particular prominent in sandstone reservoirs. For Jinqiu gas reservoir of Sichuan Basin in China, the average sand production after fracturing is 103 tons,

The impact of forced closure on proppant distribution of hydraulic fracturing in shale formations

Deep Underground Science and Engineering, EarlyView.
Research findings demonstrate that implementing forced closure within shale formations can remarkably mitigate proppant settlement, concurrently increasing the effective propped surface area from 29.74% to 38.68%. Abstract Forced closure is widely used in conventional oil and gas reservoirs to promote uniform proppant placement.

Mechanistic insights across curing regimes for enzymatic and biopolymer‐optimized reinforcement in rock masses

Deep Underground Science and Engineering, EarlyView.
This study examines the effects of curing temperature on the mechanical behavior of underground rock masses treated with enzyme‐induced calcite precipitation (EICP) and an innovative biopolymer‐modified EICP (BP‐EICP). Abstract Biocementation is an innovative and sustainable technique for reinforcing weak and weathered rock masses in natural and ...
