Thermal Recovery of Oil and Bitumen Roger M. Butler
Publisher:

A project's steam to oil ratio (SOR) measures the amount of steam that is required to be injected so as to produce one barrel of bitumen. Over the past year Excelsior Energy Limited has investigated various bitumen recovery mechanisms that could potentially reduce the large requirements for capital, fuel gas and process water associated with thermal recovery. Operators have implemented a wide range of methods to improve these operating efficiencies, applying improved technologies, heat recycling equipment, and solvent assisted recovery. Thermal recovery methods, as applied in heavy oil and oil sand deposits, and in environmental remediation, have the common objective of accelerating the hydrocarbon recovery process. Raising the temperature of the host formation reduces the oil and bitumen viscosity, and, in environmental remediation, increases vapour pressure. The company, through a secretive Calgary-based subsidiary called Sure Northern Energy Ltd., is working to unlock an estimated 60 billion barrels of raw bitumen — more than 100 kilometres west of the oil sands epicentre around Fort McMurray in northeastern Alberta. All emissions are used in the process and are injected into the bitumen.” As Nikipelo tells the story, when he took his original concept to the Alberta Research Council, Dr. In situ projects heat steam to high temperature to inject into bitumen reservoirs that are too deep to mine. , underground, devoid of mining—thermal recovery of bitumen and heavy oil: steam injection and combustion. Technology in the recovery of such reserves is advancing rapidly and suddenly this huge country with produced oil rates and reduced production costs.

STEAM ASSISTED GRAVITY DRAINGE (SAGD) The most promising thermal recovery technology is the Steam Assisted Gravity Drainage (SAGD) process. EOR is the extraction of additional oil from fully developed fields, using a variety of methods beyond conventional waterflooding or gas injection, to maintain reservoir pressure. The prize Royal Dutch is chasing is The firm is trying to commercialize what it calls a "novel thermal recovery process" invented by Shell's technology arm. With some experts predicting peak oil as early as 2030, there is more and more interest in so called "unconventional resources" such as heavy oil and bitumen. There are currently two primary different types of processes for in situ—i. Chapter 3 - Oil Sand Mining 3.1: INTRODUCTION 3.2: OIL SAND MINING 3.3: BITUMEN SEPARATION 3.4: OTHER PROCESSES REFERENCES.
