ABSTRACT Produced water (PW) is the largest and most complex waste stream generated during oil and gas production, posing significant environmental, operational, and regulatory challenges due to its high salinity, dispersed hydrocarbons, toxic organics, heavy metals, and naturally occurring radioactive materials. Although numerous studies have reviewed

Rational Design of a Multifunctional MOFs for Alkane‐Selective Gas Separation
The design of a dimethyl‐functionalized adsorbent provides insight into the simultaneous separation of CH4/N2, C2H6/C2H4, and C3H8/C3H6 mixtures. Abstract Efficient separation of light hydrocarbons—including the removal of CH4 from N2 and the purification of olefins such as C2H4 and C3H6 from their corresponding alkanes (C2H6 and C3H8)—is critical in ...

In deep coal seams, where nanopores (~2 nm) dominate, wettability effects, which govern molecule–wall interaction strength, critically control the methane storage, yet remain poorly understood.

The mechanisms whereby various parameters influence the evolution of the induced fracture geometry during pulse supercritical CO2 fracturing (PSCF) were explored through numerical simulations. A novel quantitative index of the induced fractures, termed the “matching degree” (MD), was proposed, and a theoretical framework based on the rock‐bonded ...

Water locking effect caused by surface tension severely restricts coalbed methane (CBM) productivity in multilayer reservoirs. The Songhe demonstration area features main target coal seams with overpressure, high gas content, and high gas saturation, presenting favorable CBM development conditions.

Isothermal Desorption Hysteretic Model for Deep Coalbed Methane Development
The adsorption/desorption mechanism of coalbed methane is significant for gas control and coalbed methane exploitation; scholars have done a lot of research on it and generally have confidence in that temperature, pressure, and moisture are central ...

Methane emission from U.S. coal mines : a survey [PDF]
This survey was conducted to determine the magnitude of the methane emission and control problem in U.S. bituminous coal mines. The resultant data indicate that the emission rate for any given coalbed depends primarily on the coal production rate and on ...
