Heavy oil production methods
In the past, secondary recovery techniques followed the use of primary recovery techniques—in the case of heavy oil, these techniques may be used There are several methods by which heavy oil recovery can be achieved that range from recovery due to reservoir energy (i.e., the oil flows from the well hole Some heavy oil production can be accomplished via conventional methods, such Steam-assisted gravity drainage (SAGD) is a thermal in situ recovery method Heavy crude oil cannot be extracted through standard drilling mechanisms. A number of different strategies including the use of steam and chemicals have been
1 Sep 2016 Bitumen Extraction Methods As with most other heavy oils located around the world, Alberta bitumen has a relatively high concentration of
This course deals with the latest production methods used for recovery of heavy oil using horizontal, vertical and multilateral wells, cold production, thermal 10 Jul 2012 Vapor extraction (VAPEX) has been proposed as an alternative for heavy-oil recovery in reservoirs where thermal methods face technical and Thermal methods of recovery reduce the viscosity of the crude oil by heat so that it flows more easily into the production well. Thus advanced techniques are 28 Nov 2010 [1] For this reason, extracting and refining heavy oil is much more difficult and costly than lighter conventional oil. [2] However, the existing Thermal methods are often used for producing heavy oil, among them the Steam- . Assisted Gravity Drainage (SAGD) process is one of the most widely used. These methods include: surface mining, cold production and thermal recovery. Heavy oil may also require additional processing, usually referred to as upgrading, heavy-oil recovery. The research tools and techniques span from pore-level imaging of multiphase fluid flow to definition of reservoir-scale features through
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.

Secondary recovery: injection of gas or water. When a large part of the crude oil in a reservoir cannot be recovered by primary means, a method for supplying extra
Due to their high density and viscosity, special extraction methods are needed to recover heavy oil efficiently. These methods include: surface mining, cold production and thermal recovery. Heavy oil may also require additional processing, usually referred to as upgrading, after being produced in order to be transported and refined. 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. Heavy oils typically are not recoverable in their natural state through a well or by ordinary production methods. Most require heat or dilution to flow into a well or through a pipeline. 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.
Revamping refineries to process heavier crude slates goes well beyond the requirements to meet equipment performance dictated by a shift in the quantity of
