Production of heavy oil is becoming more common in many countries, with 2008 production led by Canada and Venezuela. Methods for extraction include Cold heavy oil production with sand , steam assisted gravity drainage , steam injection , vapor extraction , Toe-to-Heel Air Injection (THAI) , and open-pit mining for extremely sandy and oil-rich deposits.
Cold Heavy Oil Production with Sand (CHOPS) CHOPS is a technique applied to both tertiary recovery of conventional oil as well as to “quasi primary” production of oil sands and oil shale. CHOPS is really nothing more than the idea that if sand filters are removed from pumping equipment and sand is produced with oil, then the two can be separated above ground. Some heavy oil production can be accomplished via conventional methods, such as vertical wells, pumps, and pressure maintenance, but these methods are considered highly inefficient. Clear and rigorous, Heavy Oil Production Processes will prove useful for those scientists and engineers already engaged in fossil fuel science and technology as well as scientists, non-scientists, engineers, and non-engineers who wish to gain a general overview or update of the science and technology of fossil fuels. New Techniques Improve Heavy Oil Production Feasibility Hamaca Area (Fig. 1) [66,672 bytes] Petrozuata's main production station is the first of Pdvsa's joint venture facilities to be in operation Cold heavy oil production with sand. Cold heavy oil production with sand (CHOPS) exploits the finding that sand ingress can enhance the oil rate by an order of magnitude or more in heavy-oil UCSS. Pressure-pulsing technology (PPT) is a flow rate enhancement method introduced in heavy-oil fields that used CHOPS between 1999 and 2001.
Cumulative heavy crude oil production for the United States at the end of 1985 was more than 16 billion barrels. California produced 63 percent of this amount. The total estimated resource for heavy oil in the conterminous United States is about 45 billion barrels.
For many of oil fields, particularly where low-to-medium gravity oils are found or where the oil viscosity is unfavourable for conventional EOR methods application, Thermal Recovery Methods are the best techniques for ultimate recovery. Vast deposits of heavy oil exist in Canada, Venezuela and USA that are amenable to recovery by Thermal Recovery. Oil Recovery Techniques • Solvent Flooding • CO 2 • Hydrocarbon Gas • Chemical Flooding • Polymer Flooding • Surfactant / Polymer Flooding (SP) • Alkaline / Surfactant / Polymer Flooding (ASP) • Conformance Improvement Methods • Thermal Techniques for Heavy Oil • Steam drive, steam stimulation, SAGD • Solvent, insitu combustion • Carbonate Reservoirs and Wettability Unconventional oil production is commonly seen as more costly than conventional oil production, less efficient, and is likely to cause more environmental damage. The way to further increase oil production is through the tertiary recovery method or EOR. Although more expensive to employ on a field, EOR can increase production from a well to up to 75% Crude oil development and production in U.S. oil reservoirs can include up to three distinct phases: primary, secondary, and tertiary (or enhanced) recovery. During primary recovery, the natural pressure of the reservoir or gravity drive oil into the wellbore, combined with artificial lift techniques (such as pumps) which bring the oil to the surface.
In the past, a wide variety of nonthermal heavy oil recovery methods have been tested, with limited success. These methods range from waterflooding to improved floods and "pattern rotation" type techniques. This paper presents a comprehensive survey of the nonthermal heavy oil recovery methods, which have been tested in field and laboratory.
