Abstract: Facies modelling and reservoir structural analysis was carried out using data from the X-field. Genetic units were characterized for all reservoir units from wireline logs. Based on the response of different genetic units, and the sedimentary structures displayed in the core log data, five reservoir intervals were defined (RES 01, RES 02, RES 03, RES 04, and RES 05). Results from seismic analysis suggests five exploration play facies, namely, the A facies (distal basin plain), the Bh facies (distal basin plain), the Cbh facies (reworked offshore bar/distal marine slope), the Cbl facies (distal basin plain), the D facies (proximal slope channel), and the E facies (proximal slope channel).......

Abstract: The hydrogeochemical characteristics ofgroundwater in Phagi block of Jaipur district, Rajasthan were evaluated during pre-monsoon seasons to assess its quality. Thirty eight groundwater samples from bore wells/dug wells were collected and analyzed for pH, EC, TDS, total hardness, major anions and cations. Fluoride concentration ranges from 0.02 to 10.50 mg/l. The probable source of fluoride in the study area is appears to be geogenic due to high residence time.

Abstract: Mine activity plays dynamic role in the overall development and progress of any country. The developments of mining practices, significant increase the environmental risks. In Bangladesh, the only hard Rock Mine is situated at Maddhapara, Parbatipur, Dinajpur which produce granite and most of the hard rock production in Bangladesh comes from the underground hard rock mines. During the FY 2018-19, a total 10,67,646.63 MT of granite was extracted from the mine with huge amount of water (~ 58,940 L /hour) which discharge to the nearby environment. The aim of the research is to find the water quality that discharge to the environment. For this point of view, eight......

| Title | : | Mitigating the Impact of Swelling Clays on Wellbore Permeability in Geothermal Wells: A Case Study of Olkaria Geothermal Field, Kenya |

Abstract: Permeability of a geothermal field is an important parameter in the sustainable utilization of the geothermal fluids. However, one of the major problems experienced at Olkaria is by the presence of swelling clays (smectites), which affect permeability by reducing fluid flow into the wellbore. Olkaria geothermal field is characterized by high quantities of swelling/ smectite clays found in faults that laterally seal potential storage reservoirs. This study aimed at mitigating the overall impact of swelling clays on the well bore permeability in geothermal wells. A quantitative research method was adopted together with an experimental research design. Analysis of data entailed computing......

Abstract: The present study was carried out to assess sedimentological characters and to evaluate the potential effects of human activities and natural occurrences of heavy metal levels in marine sediments. Ten marine sediment samples from northern area of Suez Gulf were collected and analyzed using different analytical techniques. Metal Pollution Index, Geo-Accumulation Factor, Enrichment Factor, Contamination Factor, Pollution Load Index and Potential Ecological Risk Index were used for ecological assessment. ArcGIS technique was used to interpolate the obtained data in order to create spatial distribution maps. The concentrations of the studied heavy metals descended in the following.....
