Quantifying the technical geothermal potential from shallow borehole heat exchangers at regional scale

open access: yesRenewable Energy, 2021
The extraction of shallow geothermal energy using borehole heat exchangers (BHEs) is a promising approach for decarbonisation of the heating sector. However, a dense deployment of BHEs may lead to thermal interference between neighbouring boreholes and ...

DETERMINATION OF METHANE DESORPTION ZONE FOR THE DESIGN OF A DRAINAGE BOREHOLE PATTERN (CASE STUDY: E4 PANEL OF THE TABAS MECHANIZED COAL MINE, IRAN)

open access: yesRudarsko-geološko-naftni Zbornik, 2021
Underground coal mining is known as one of the major sources of methane emissions which mainly occurs after underground coal extraction. Rock strata in-situ methane can potentially be the most significant hazard in coal mining operations.

Depthwise evaluation of total dissolved solids and arsenic from a drilled borehole near River Ravi, Lahore, Pakistan

open access: yesJournal of Water and Climate Change, 2023
Groundwater pollution is now a significant threat to the ecosystem. The untreated disposal of municipal and industrial wastes through drains into water bodies (rivers, lakes, and canals) is the primary source of contamination.

Borehole instabilities in the KTB main borehole

open access: yesJournal of Geophysical Research: Solid Earth, 1997
Borehole instability has been a central problem for drilling operations and borehole measurements within the German Continental Deep Drilling Project (KTB) main borehole, which has been drilled entirely through crystalline rocks, mostly paragneisses and metabasites.

A Review of Potential Cementing Systems for Sealing and Support Matrices in Deep Borehole Disposal of Radioactive Waste

open access: yesEnergies, 2019
Cementitious grouts are being developed for use as sealing and support matrices (SSMs) in deep borehole disposal (DBD) where temperatures do not exceed 190 °C. They will seal radioactive waste containers into the bottom 2 km of holes drilled up to 5
