Cuttings transport simulation workflow. ABSTRACT Efficient cuttings transport is essential for wellbore stability and minimizing non‐productive time in deviated and horizontal wells. This study applies global sensitivity analysis (GSA) to evaluate the influence of 14 drilling parameters on cuttings transport using WellPlanTM hydraulic simulations ...

Aiming at the difficulties in accurately calculating the movement and deformation of small‐sized, deep‐buried dams with a significant height‐to‐depth ratio in deep fully mechanized caving mining, this study proposes to separate the analysis of surface and dam deformation.

This study reveals the temporal and spatial evolution law of roof separation under the karst aquifer and the dynamic water inrush mechanism of roof separation. The FAHP–EWM–CRITIC combination weighting method was established to obtain the risk zoning of bed separation water inrush in a karst landform mining area. ABSTRACT Coalfields in northern Guizhou

ABSTRACT Field visits are common phenomena with non‐governmental organisations in Uganda. During these visits, Ugandan national staff guide visitors on series of meetings and interactions in the field. Following an actor‐oriented approach and drawing on ethnographic data on 14 field visits, this paper understands the field visit as a microcosm for the ...

ABSTRACT The Mediterranean is particularly sensitive to rapid climate changes (RCCs) during the Holocene. An increasing number of natural climate archives revealed that socio‐economic developments were influenced by such RCCs since the Palaeolithic. However, multi‐millennial and high‐resolution archives are still rare and often located in mountainous ...

The possibilities of heat pumps utilisation for family houses and flats fumigation [PDF]
Heat pumps (HPs) with the help of electricity use a renewable energy source to supply heat for homes or industrial buildings and to heat tap water. HP is a heating unit that will provide us with heat for our home for some 20 to 30 years to come and has a

Abstract Holocene relative sea level (RSL) changes were reconstructed from four sites along the less‐studied southern Solway Firth. A multiproxy approach, including lithostratigraphical and biostratigraphical analyses, combined with radiocarbon dating, produced ten sea level index points (SLIPs).
