Petroleum - Status of the world oil supply

Petroleum - Petroleum - Status of the world oil supply: On several occasions—most notably during the oil crises of 1973–74 and 1978–79 and during the first half of 2008—the price of petroleum rose steeply. Because oil is such a crucial source of energy worldwide, such rapid rises in price spark recurrent debates about the accessibility of global supplies, the extent to which producers ...

Environmental impacts of oil sands

Water Impacts: The extraction of bitumen from oil sands requires a large amount of water, and thus water use is a concern when looking at oil sands extraction. Water used in the oil sands can be recycled, but only small amounts of this water are returned to the natural cycle.

The Open Petroleum Engineering Journal

Development of Contactless Sand Production Test Instrument. Sand production is an important factor affecting reservoir exploitation. Excessive sand production affects the oil well life, causes the damage to the oil recovery device and brings serious hidden danger in the process of safety production.

A Feasibility Study of Tar Sands Exploitation in Trinidad and

The continuous decline in Trinidad and Tobago's crude oil production has accelerated the drive to boost oil production from unconventional sources. One such source is a tar sands deposit with estimates of original volume in-place between 400 million and 2, 000 million barrels of bitumen.

Oil Sands Extraction and Processing

Currently, 20% of oil sands reserves are accessible via mining techniques. Large shovels scoop the oil sand into trucks which then move it to crushers where the large clumps of earth are processed. Once the oil sand is crushed, hot water is added so it can be pumped to the extraction plant.

Modeling Sand Occurrence in Petroleum Production

Oct 01, 2019 · This paper presents an advanced model to predict sand occurrence and accurately estimate volumetric sand produced in petroleum production. The sand factors K s (t), derived from the linear time combination of likelihood of occurrence λ m (t) of K RS and K FS, were used to determine sand occurrence and estimate its volumetric production around well bore systems.

How Things Work: Canada’s Oil Sands

As we mention in the description of the process, oil sands production requires an enormous amount of water (4 barrels of water for each barrel of oil). Further, the toxic tailings ponds — where the contaminated water leftover from pre-processing the bitumen is stored — pose disturbing health and environmental risks.


Producing the oil with sand has a quicker and higher rate of recovery than producing the same well in cold heavy oil production without sand. However, harsh abrasive conditions are critical for artificial lift life span and result in very high operating costs. HSE CHALLENGE Bringing the entire mixture of sand, water and oil to the surface

Oil and Gas Extraction Effluent Guidelines

The industry generates wastewater from the water extracted from the geological formations and from chemicals used during exploration, well drilling and production of oil and gas. These activities are included within NAICS code 211111, Crude Petroleum and Natural Gas Extraction. (Note: the NAICS group listings are provided as a guide and do not ...

Crude Oil Extraction and Drilling Methods

Oil is produced (extracted) using different methods depending on geology and location. After recovering the oil, it is sent to refineries to create refined products we use every day, such as gasoline. The first efforts to tap the oil sands resource began in the mid 20th century using hot water to separate bitumen from sand.

Experimental Study of Sand Production during

Silty-clay reservoirs are a weak point in sand production and sand control studies due to their low economy. However, China’s marine natural gas hydrates (NGH) mostly exist in silty-clay sediments, which restrict the sustainable and efficient development of NGH. In order to study the sand production of hydrate silty-clay sediments, hydrate production experiments in vertical wells and ...

Experimental Investigation on Sand Production during Non

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 problem that endangers the safety of hydrate exploitation. The aim of this study is to understand sand production in during hydrate exploitation.

Oil and the environment - U.S. Energy Information

An oil production technique known as hydraulic fracturing, or fracking, is used to produce oil from shale and other tight geologic formations. This technique has allowed the United States to significantly increase domestic oil production and reduce U.S. oil imports. Hydraulic fracturing has some effects on the environment.
