The geological storage of CO2 is a critical technique for reducing emissions, which significantly contributes to the mitigation greenhouse effect. Currently, often geologically stored in coal seams, hydrocarbon reservoirs, and saline aquifers order store improve oil gas recovery simultaneously. Shale formations, as candidates storage, are drawing more attention because their rich volumes. throu...

There are many oil and gas fields around the world where vast number of wells have been abandoned or suspended, mainly due to depletion reserves. Those (AOGWs) often located in areas with a prospective geothermal potential might be retrofitted system without high-cost drilling. In Poland, there thousands wells, either operating, negative, that used for different applications. Thus, aim this pap...

Leakage from abandoned wells and geologic faults represents one of the greatest risks to the integrity of geologic CO2 sequestration sites. The ability to detect leakage in a timely manner is, therefore, crucial for mitigating the potential adverse impacts of leakage to the public and environment. We present an inversion approach for recovering both leakage locations and rates by using observed...

In this study, possible sources of extremely high concentrations of arsenic (reaching as high as 561.5 μg/L) in the shallow groundwater of Simav plain, Turkey is studied in order to understand probable mechanisms of contamination. It has been found out that the major source of arsenic in groundwater is arsenic containing geological formations in and around the vicinity of the plain. However, th...

The Turaszówka crude oil field is situated within the borders of Krosno town. The oil resources are nearly depleted. Many of the boreholes have already been liquidated. Currently, only 22 boreholes are being exploited. Eight of them are watered and exploiting oil along with the reservoir water. The boreholes were submitted for producing the geothermal energy, because of their location. They are...

An 18-month chronic bioassay was conducted using ICR mice to determine whether health hazards are associated with exposure to a mixture of chlorinated alkanes and alkenes (CA) with composition similar to the contaminated water from drinking wells near an abandoned RCA factory. All test animals died spontaneously or sacri ced were examined to evaluate the in uence of the CA mixture on the incide...

In 2009, we identified a TCE plume at an abandoned landfill that was located in a low permeable silty-clay aquifer. To treat the TCE, we manufactured slow-release potassium permanganate cylinders (oxidant candles) that had diameters of either 5.1 or 7.6 cm and were 91.4 cm long. In 2010, we compared two methods of candle installation by inserting equal masses of the oxidant candles (7.6-cm vs 5...
