Thermal Recovery Methods for Heavy Oil Fields Training

This course is designed to cover all the traditional and modern Thermal Recovery Methods used in the oil industry for Heavy Oil recovery. Perhaps no other single subject dominates the oil industry like thermal recovery. 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. Thermal Recovery is usually applied to heavy to medium oils, however these methods can be applied to any field being considered and be competitive with alternative methods. The course consider the following methods: Cycle Steam Injection, Double Injection Nitrogen-Steam, CO2-Steam Injection, Flue Gas-Steam Injection-This methods have given excellent results in China and Louisiana (USA), Steam Drive Process, Hot Water Injection Processes, In Situ Combustion Processes, Cold Heavy Oil Production with Sand (CHOPS),  Vapor Extraction Method (VAPEX) and Steam-Assisted Drainage (SAGD).

Chemical floods offer the only chance of commercial success in many depleted and waterflooded reservoirs. Chemical flooding is here to stay because it holds the key to maximizing the reserves in our known reservoirs

Water Shut-Off and Conformance Improvement Technologies Training

Approximately 20 billion barrels of water are reinjected in the US every year. Any technology that minimizes the amount of water or gas produced in conjunction with the produced oil would have a significant impact on the energy consumption and on the cost oil production. There are many factors, such as the presence of thief zones or high permeability zones, fractures and water coning which lead to an increase in water production. In an attempt to block out the undesired water production and increase the volumetric sweep efficiency of on-going waterfloods, the industry has used crosslinked polymer gels. The process involves strategically injecting a Gelling fluid into water coning well or into a high permeability watered out zone, restricting flow in that zone and redirecting water flow into the lower permeability unswept oil zones. Thus water shut off and conformance-control treatments can be used to generate relatively large volumes of incremental oil production with low costs and selectively, targeted small volume treatments, which extends the economic lives of marginal and mature wells.

WAG-Water Alternating-Gas EOR Processes Training

Water alternating gas (WAG) injection are improved oil recovery methods that involve three-phase fluid flow. It was originally proposed as a method to improve the sweep efficiency of gas by using water to control the mobility ratio and to stabilize the front (Caudle and Dyes, 1958; Christensen et al., 1998). WAG injection can lead to improved oil recovery by combining better mobility control and contacting upswept zones, and by leading  to  improved microscopic displacement. WAG flooding has been successfully applied to more than 60 oilfields worldwide. This course will present WAG Miscible, WAG Immiscible, WAG alternating different types of Hydrocarbon Gases and Non-HC such as N2 and CO2 Gases. Also, the course will present and study the Factors Influencing Wag Process Design such as Fluid properties and rock-fluid, Availability and composition of injection gas, Heterogeneous Permeability, Injection Pattern, Capillary pressure, Relative permeability and Wettability. A WAG Process is presented and discussed in the course as well as Field cases and Laboratory research cases and results.
