Enhanced Recovery Methods for Heavy Oil and Tar Sands by James G. Speight

By James G. Speight

Recent oil expense fluctuations proceed to emphasize the necessity for extra effective restoration of heavy oil and tar sand bitumen assets. With traditional construction gradually declining, advances in greater restoration may be required in order that oil construction could be prolonged and reservoirs last more. a realistic consultant on heavy-oil comparable restoration equipment is vital for all thinking about heavy oil creation. To feed this call for, James Speight, a well-respected scientist and writer, offers a must-read for all scientists, engineers and technologists which are considering construction enhancement. In Enhanced restoration equipment for Heavy Oil and Tar Sands, Speight offers the present tools of restoration for heavy oil and tar sand bitumen expertise, damaged down by way of thermal and non-thermal equipment. An engineer, graduate scholar or expert operating with heavy oil, upcoming and present, will drastically make the most of this much-needed text.

Sample text

An additional term, potential reserves, is also used on occasion; these reserves are based upon geological information about the types of sediments where such resources are likely to occur, and they are considered to represent an educated guess. Then, there are the so-called undiscovered reserves, which are little more than figments of the imagination. The terms undiscovered reserves or undiscovered resources should be used with caution, especially when applied as a means of estimating reserves of petroleum.

Additional wells or reservoir performance data), the range of uncertainty in the estimated ultimate recovery for that accumulation should be reduced. The low estimate, best estimate, and high estimate of potentially recoverable volumes should reflect some comparability with the reserves categories of proved reserves, proved plus probable reserves, and proved plus probable plus possible reserves, respectively. While there may be a significant risk that subcommercial or undiscovered accumulations will not achieve commercial production, it is useful to consider the range of potentially recoverable volumes.

When consolidated into rock, sapropel becomes oil shale, bituminous shale, or boghead coal. The principal components are certain types of algae that are rich in fats and waxes. Minor constituents are mineral grains and decomposed fragments of spores, fungi, and bacteria. The organic materials accumulate in water under reducing conditions. 5 VALIDITY OF THE DEFINITIONS The validity of the definitions related to petroleum, heavy oil, and tar sand bitumen is subject to much scrutiny and, consequently, criticism.
