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.

Oil Sands Development: A Health Risk Worth Taking?

This is known as in situ production. Unprocessed oil sands contain 3–18% bitumen by weight, along with 2–10% water and 80–85% mineral matter (sand, clay, etc.). Bitumen is composed chiefly of polycyclic aromatic hydrocarbons (PAHs), sulfur, lead, mercury, arsenic, nickel, vanadium, chromium, and selenium.

Hydraulic Fracturing Water Usage

The use of horizontal well high volume fracturing has accelerated significantly since 2005. The current total amount of water used for hydraulic fracturing as a percentage of water use by sectors is not yet available. As soon as the USGS publishes its report for 2010, this section of the website will be updated accordingly.

1.2. Components of the Petroleum Production System

The reservoir fluid consists of oil, gas (even if the flowing bottomhole pressure is larger than the bubble-point pressure, gas is likely to come out of solution along the well), and water. Traditionally, the oil, gas, and water are not transported long distances as a mixed stream, but instead are separated at a surface processing facility ...

13 Pros and Cons of Tar Sands – Vittana.org

The pros and cons of tar sands show us that short-term gains happen, but at the expense of long-term problems. We must work to find a solution that will limit emissions and habitat damage to benefit from this natural resource. If we cannot find this solution, we may run out of bitumen one day and leave a more polluted planet for future generations.

Oil Extraction: How Oil Production Impacts the Rainforest

Jan 07, 2013 · At times, oil companies pay their agreed-upon fees and royalties, which end up in the hands of corrupt government bureaucrats before they can be distributed to the communities. Corruption and the oil business often go hand in hand. Despite booming demand for oil and gas, the benefits of oil production accrue to few people in most tropical ...
