Petroleum Exploration and Production: Past and Present
Petroleum exploration and production in the Nigeria's Niger Delta region and export of oil and gas resources by the petroleum sector has substantially improved the nation's economy over the past five decades. However, activities associated with petroleum exploration, development and production operations have local detrimental and significant impacts on the atmosphere, soils and sediments ...
Where and how extraction proceeds « World Ocean Review
Because water and oil have similar densities, it can happen during secondary production that the injected water flows past the oil and into the well, with the result that very little oil is produced. For this reason, tertiary methods are used to decrease the viscosity of the oil. Hot water or solvents are pumped into the reservoir for this purpose.
Petroleum Waste Treatment and Pollution Control
The petroleum industry can be divided into four sectors: (1) exploration, development, and production; (2) hydrocarbon processing (refineries and petrochemical plants); (3) storage, transportation, and distribution; and (4) retail or marketing. Air emissions, wastewater, and solid wastes can be generated in these sectors.

Oil and gas: Water treatment in oil and gas production
Connate water is the water trapped in the rock during its formation and over its life its composition can change. Formation water is water which has been formed in situ and becomes trapped with the hydrocarbons below the impermeable cap rock. When an oil well is brought into production the oil, gas and water are co-produced. Oil/water separation

Geomechanical Challenges in Petroleum Reservoir Exploitation
petroleum resource base of about 14-15 Tb (1012 barrels - USGS)1, about 9.5-10 Tb are viscous oils (>100 cP in situ); of this viscous oil, ≈75% is found in high-porosity weak sandstones, and 15% in
Mixing Oil and Water - USGS
The USGS estimates that, during production of the oil and gas in the Eagle Ford Group, a mean of about 177 billion gallons of produced waters could be brought up along with the oil and gas. Fine-grained silica sand is mixed with chemicals and water before being pumped into rock formations to prevent the newly created artificial fractures from ...

Journal of Petroleum and Gas Engineering - articles
Sand production is a major concern during petroleum exploitation from unconsolidated sandstone reservoirs. For efficient management, sanding predictive tools are necessary. While several models have been developed for sanding in oil reservoirs, gas and gas condensate reservoirs have received little attention because of the widespread belief ...
Oil production: Filtration and efficient petroleum
Jun 05, 2009 · Although the production of oil from tar sands is, on the global scale, nowhere near that of pumped crude oil, its fluid flow rates will become large, as the reserves are developed. These will include, besides the produced oil, the residual water from the processing of open-cast sands, or the recovery of oil from underground. Crude oil treatment
What Are the Oil Sands | Canada's Oil Sands Facts
Apr 14, 2020 · The oil sands (or tar sands as they are sometimes inaccurately referred to), are a mixture of sand, water, clay and a type of oil called bitumen. Thanks to innovation and technology we can recover oil from the oil sands, providing energy security for the future. Oil sands are a mixture of sand, water and bitumen (oil that is too heavy or thick to flow on its own).

Water in the Oil and Gas Industry | American Geosciences
The oil and gas industry consumes and produces water. Water is used to drill and hydraulically fracture (“frack”) wells, refine and process oil and gas, and produce electricity in some natural gas power plants. Water is also naturally present in the rocks that contain oil and gas and is extracted along with the oil and gas as “produced water”, sometimes in large quantities. The quantity and quality of water used, produced, and disposed of or re-used varies enormously depending on local geology,
