Heavy oil production methods
Revamping refineries to process heavier crude slates goes well beyond the requirements to meet equipment performance dictated by a shift in the quantity of Specifically, enhanced oil recovery is used to recover oil trapped in porous rocks and the heavy oil that is too viscous to flow. The three methods for tertiary recovery are: chemical enhanced recovery, thermal enhanced recovery, and miscible enhanced recovery. 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. Toe to heel air injection (THAI) is a method that employs combustion—which liquefies the heavy oil so it can be extracted from the reservoir. One of the most successful and best known methods of tertiary thermal recovery is steam-assisted gravity drainage (SAGD) process, which has returned production efficiencies up to 60% or better in Canadian heavy oil reservoirs. 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. 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.

heavy-oil recovery. The research tools and techniques span from pore-level imaging of multiphase fluid flow to definition of reservoir-scale features through HO is a thick, viscous, tar-like crude oil that does not pump easily or flow well. This presents huge challenges when estimating reserves and extracting them from Steam injection is currently considered the most effective method for heavy oil production. However, there are certain situations where it may not work very well. 5 Apr 2007 DOI: 10.1016/j.fuel.2019.116716. N. A. Mironov, D. V. Milordov, G. R. Abilova, S. G. Yakubova, M. R. Yakubov.

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,
