Evaluation of Present Tectonic Stress Field and Permeability of Coalbed Methane Reservoirs by Inversion of Logging Data From Longtan Formation, Dahebian Block

Energy Science &Engineering, EarlyView.
ABSTRACT The permeability of coal reservoirs is predominantly controlled by the present tectonic stress field. This study systematically integrates macro‐ and micro‐scale analytical methods to investigate the controlling mechanisms of tectonic stress on pore‐fracture characteristics and permeability in the Longtan Formation coal reservoirs.

Acoustic Emission Time–Frequency Characteristics and Response Mechanism of Damaged Sandstone Under the Influence of Lithology

Energy Science &Engineering, EarlyView.
ABSTRACT Coal seam mining will inevitably cause damage to overlying rock structure, and then affect mine safety production, and even surface ecological environment. This study investigates two types of damaged sandstone samples, prepared through cyclic loading–unloading and uniaxial compression tests.

Forecasting Energy Efficiency in Manufacturing: Impact of Technological Progress in Productive Service and Commodity Trades

Journal of Forecasting, EarlyView.
ABSTRACT This paper employs the theory of biased technological progress to assess the effects of technological advancements across diverse trades, with a particular emphasis on predicting energy efficiency. A translog cost function model is developed, integrating five critical types of energy inputs.

Geological Screening for CO2 Storage in Deep Saline Aquifers in the Lower Mainland British Columbia (LMBC), Canada

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Deep saline aquifers and depleted reservoirs are prime candidates for CO2 storage, but feasibility assessments remain limited in regions with little oil and gas activity, such as the Lower Mainland of British Columbia (LMBC), Canada. This study evaluates the CO2 storage potential of the Georgia Basin strata beneath the LMBC, focusing on three ...
