Gassy and Greasy

How much oil and gas has been produced? How much is left? Estevan - Roughly 51.5 million barrels were produced in 2013, with an estimated 59.6 billion barrels remaining. Swift Current - Produced an upwards of 57 million barrels, with an estimated reserve of 50 billion barrels remaining. Lloyminster/Kindersley - The largest of the three zones, L/K produced a whopping 64 million barrels in 2013 and contains an estimated reserve of over 100 billion barrels.

All oil and gas producing areas in Saskatchewan are located in the Phanerozoic Basin!

Gassy and Greasy

Estevan - Located in the southeast corner of the province, the Estevan oil sector surrounds the city on all sides. Geography - Much like the long stretch of land along the western border, the Estevan oil and gas fields are mostly flat, the odd rolling hill. This, just like the predominant part of the province, is due to the fact that ancient glaciers moved across the land and effectively bulldozed all landscape in their path, carving out a flat niche as it is today.

Swift Current - Around the Swift Current oil and gas area, most of the drills are loacted to the more west of the city, along with some south. Geography - In the extreme southwest of the province, Cypress Hills are the highest point in Saskatchewan, a small corner missed by the movement of glaciers. These high, still rolling hills trail into smaller foothills and gently roling land to the immediate west of Swift Current, flat from glacial movement. The Hills themselves were formed by the remnants of erosion after the initial uplift of the Rocky mountains, casuing the plan the hills lay on to be elevated.

Lloydminister/Kindersley stip - Stretching in a long strip down Saskatchewan's western border, the oil and gas strip extends and includes both cities. Geography - The geography of the Lloyd/Kindersley stretch is relatively the same as it stretches along the border. Gentle rolling hills and the odd river make up most of the land, which suggets that ancient glaciers moving across the province bulldozed any significant hills or valleys into nothing but smooth rolling hills.

What type of petroleum is in each area? Lloydminister/Kindersley - A primary producer of heavy crude oil, this area has a higher sulfur content.Estevan - Producer of light crude oil, this area produces smoother and cleaner oil, with a lower sulfur content. "Sweeter".Swift Current - Situated in the middle of the spectrum, the Swift Current area produced medium crude oil, where the sulfur content varies between sweet and sour.

How old is the rock?Lloydminster - Roughly 70 million years oldEstevan - 65 million years oldSwift Current - 99 million years old(65 million in the Cypress Hills area)

Types of rock in each zone:Lloyminster - Siltstone, sandstone, shaleEstevan - Conglomerate gravel, sandstone, carbonate shaleSwift Current - Sandstone, shale

How deep are the wells?Estevan - Estevan has primarily shallow wells, ranging from 5 thousand to 6 thousand feet deep. The deepest well is 3km deep.Lloyd/Kindersley - The average range of wells in this strip is between 4 thousand to 5 thousand feet deep.Swift Current - Averge depth of wells in the Swift Current area are 5-6 thousand feet deep. Types of TrapsLloyd/Kindersley - Primarily anticline traps, or pinchout traps.Estevan - The largest oil resevoirs are located within stratographic traps. Swift Current - Like Lloyminister, primarily anticline taps re found in the Swift Current Area.
