Downloadable! Sand production is the process in which formation sand and gravel would migrate into the wellbore by the flow of reservoir fluids. This is a significant problem that endangers the safety of hydrate exploitation. The aim of ...
resistivity of petroleum saturated sand is much lower (2200 ohm m) but is still higher than that of any non-polluted sand. This study is therefore aimed at determining the geoelectric response of water saturated and hydrocarbon impacted sand using the electrical resistivity method of geophysics.
5. Conclusions Petroleum contamination and environmental degradation associated with exploitation and production of petroleum resources has clearly impacted the natural environment, human health and safety, physical and socio–economic environments in the Niger Delta.
Hydrocarbon reservoir properties, connectivity of petroleum system, hydrocarbon type and gas-oil and oil-water contacts are determined to calculate potential recoverable volumes. This is usually done by drilling more appraisal wells around the initial exploration
In a modern world there is a problem of underground water contamination, which can be classified as storage tanks and petroleum exploitation, septic systems, uncontrolled hazardous waste, landfills, chemicals and road salts, atmospheric contaminants. In our article we consider underground water contamination caused by petroleum exploitation.
how does water figure in fossil fuel development? Water is ubiquitous in oil and gas production Water is used in all stages of oil and gas development, extraction, and processing (WWAP 2014). Operations may consume water or remove large quantities of water; the water is then used for drilling, washing, and processing.

Importance of produced water. Because the produced water is not usually a revenue stream, the emphasis on water-flow prediction, technology development, and engineering application has not traditionally been a major focus of oil- and gas-production engineering.
The flow and production mechanism within coalbed methane has more similarity to shale oil and gas than to the production of oil or gas associated with tight sedimentary rocks. The initial flow is dictated by the stored gas and water in the fracture network (both the orthogonal butt and face cleats as illustrated in Fig. 3.10). Subsequent long ...
