Water quality must be maintained so that it remains beneficial to humans and other living things, as a means of improving public health. The requirements for clean water have been regulated in Permenkes No. 416 1990 concerning Requirements Supervision Quality. purpose this study was analyze with hardness pH parameters hygiene sanitation used by the people Semin village, district, Gunungkidul di...

Abstract Arctic-boreal regions are experiencing major anthropogenic disturbances in addition to intensifying natural disturbance regimes as a consequence of climate change. Oil and gas (OG) activities extensive the region western North America, large portion which is underlain by permafrost. The total number distribution OG wells their potential fate remain unclear. Consequently, collective imp...

Abstract Lower Miocene rift sediments of the Nukhul Formation are one prominent hydrocarbon producers in Gulf Suez basin. In this study, we focused on oil producing sandstones Abu Rudeis-Sidri Field, located east central Suez. is characterized by low amplitude seismic reflectors and represents youngest identified reflector (Lower Miocene) study area. Petrophysical assessment was carried out usi...

The October 30, 2020 Samos earthquake (Mw 6.6) affected the Aegean Sea and environs, caused destruction loss of life in city İzmir located 70 km away from epicenter. Before this earthquake, water resources were monitored areas Bayraklı, Gülbahçe, Seferihisar. For purpose, 10 groundwater monitoring wells drilled Bayraklı area, where level, temperature, electrical conductivity changes at 1-h inte...

BACKGROUND AND AIM. The presence of active or inactive (i.e., postproduction) oil and gas wells in neighborhoods contributes to ongoing pollution. Racially discriminatory neighborhood security maps developed by the U.S. federal Home Owners Loan Corporation (HOLC) 1930s may contribute environmental exposure disparities. Our aim was determine whether receiving worse HOLC grades associated with mo...

Background: Seawater intrusion refers to the infiltration of seawater into groundwater, either naturally or artificially, due extraction groundwater for domestic purposes. can have wide-ranging impacts on various aspects life, including health issues, reduced soil fertility, structural damage, and contamination. In Kendari District area, people rely springs, dug wells, drilled wells fulfill the...

This research analyzed the reservoir quality of Mfamosing Limestone with a view to classifying it as potential rock within Calabar Flank. Materials used in this are processed seismic data acquired around flank and well logs three wells (A, B, C) drilled at different periods study area, core mud log data. The procedure involved prospect identification mapping, structural stratigraphic analysis, ...

Predicting the PDC bit performance during drilling operation is important for cost effectiveness of operation. The majority bits are assessed based on their that relative to offset wells. Determination mechanical specific energy (MSE) in real time and compare it with known MSE a sharp assess life has been utilized by several operators past. However, still cannot be used predict exploration well...

Among a large number of geophysical well logging methods, the spontaneous potential (SP) is most demanded one for studying geological sections, and widely used in all drilled wells. This paper presents brief review main studies on enhancement theoretical model SP phenomenon, creation algorithms numerical modeling data. First all, we discuss that were conducted shortly after discovery phenomenon...
