Abstract
<b>The influence of oil well on the water generation from the potiguar basin / Brazil
Highlights
The demand for oil and its by-products has raised world production over the last decade (2006 to 2015) to a production level of more than 92 million barrels per day (Agência Nacional de Petróleo [ANP], 2016)
A geological environment that had an intense deposition of organic matter, associated with a burial and specific physicochemical conditions tends to gather the necessary conditions to generation of oil in the matrix rocks (Stephenson, 1992). When this oil is extracted through the wells, whether onshore or offshore, it produces aqueous waste effluents called wastewater from oil fields or produced water (PW), responsible for the largest amount of residues from the production and exploration of crude oil (Stephenson, 1992; Mondal & Wickramasinghe, 2008), especially in mature fields, when there is an excessive production of water (Figueredo et al, 2014)
After three iterations, following the assumptions of multiple regression, three variables were excluded from the model due to their low statistical significance, such as: API Gravity, horizontal wells and directional wells for the years 2014 and 2015 and the variables API Gravity, Horizontal wells and Vertical wells, for the year 2016
Summary
The demand for oil and its by-products has raised world production over the last decade (2006 to 2015) to a production level of more than 92 million barrels per day (Agência Nacional de Petróleo [ANP], 2016). With the increase in oil production, there is an increase in the quantities of produced water (Clark & Veil, 2009; Nasiri, Jafari, & Parniankhoy, 2017), which requires a severe intervention with sustainable practices in order to avoid environmental damage. This environmental problem, originated from the generation of water produced in the oil fields, promotes damages to the sustainability of the oil industry, ratifying the search for technologies that causes less impact to the environment (Figueredo et al, 2014). When this oil is extracted through the wells, whether onshore or offshore, it produces aqueous waste effluents called wastewater from oil fields or produced water (PW), responsible for the largest amount of residues from the production and exploration of crude oil (Stephenson, 1992; Mondal & Wickramasinghe, 2008), especially in mature fields, when there is an excessive production of water (Figueredo et al, 2014)
