The oil and gas industry often contain a certain amount of CO2, H2S and chlorine compounds. H2S can cause sour corrosion and sulfide stress cracking (SSC) of stainless steels. Failures due to H2S are usually sudden with no warning. SSC is the worst type of corrosion in the presence of H2S. Many methods have been suggested to mitigate SSC and other corrosion issues in wet and sour service. Considering the design and the operation environments, the most practical solution is to change the materials of construction and select alternative material and/ coating to suit the specific need.
As increasing international competition and environmental pressures, Canadian oil sands producers must develop new technologies to more competitively deliver their product to market that have lower greenhouse gas (GHG) emissions. Flow Control Devices (FCDs) are one such technology. These devices are placed in the injection and production wells and enable more efficient access to the reservoir. The result is improved economics and thermal efficiency which directly is tied to GHG emissions.
Down hole tools in the oil and gas (O&G) industry has long been used to increase the oil recovery and limit unwanted products like water, sand and steam. RGL is a world leader on both Sand control and Flow control products, with a focus on technology driven solutions. Various sand screens, slotted liner designs, flow control devices and shifting tools are in development in the engineering and research group. A critical understanding of the science behind the measured phenomena is pursued with fundamental research in partnership with the UofA.
Oil recovery processes use flow control devices (FCDs) to ensure uniforms flow of fluids with minimized potential for well failure. These devices operate by restricting the flow through nozzles causing its velocity and pressure to significantly change. For the flow to keep its momentum, its pressure has to drop which unfortunately increases the likelihood of local well failure to occur. In this research, the performance of various nozzle types will be tested to investigate the effect of geometry on the pressure drop.
This project will develop practical workflows, algorithms and programming codes for inferring unknown reservoir properties from distributed temperature and acoustic sensing data. In-situ pressure and flow conditions can be interpreted from downhole fiber signals gathered in real time, which are used to estimate unknown heterogeneous reservoir parameters continuously. Machine learning methods will be incorporated to facilitate the handling of large amount of measured data and computations more efficiently.
Sand production during extraction of bitumen in oil sand industry is the most significant challenge which results in many operational problems such as erosion of downhole and surface equipment, collapse of the formation, and subsequently a dramatic increase in capital and operating costs of the production plant. Mesh weaves are currently used to reject sand during production and mitigate these effects. The proposed research project will investigate the flow, and solid retention capacity of different mesh weaves in various test cells.
In this project, we develop a framework to use the data from fiber sensing technologies to smart monitoring of Oil and Gas Reservoirs. The project involves extensive lab experiments simulating different monitoring conditions. Different configurations for installation of sensing equipment will be examined. The optimum location of tubing will be also determined. Signal processing methods will be used to extract useful information from the raw fiber-sensed data. Through experiments, we will record and analyze the relationship of fiber-sensed signals and the flow conditions.
This research aims at better understanding the performance of Wireline Applied Stimulation Pulse (WASP) technique in formation damage reduction in oil and gas wells. Hydrocarbon production rate decreases as a result of plugging the sand control devices located in the wellbore region. Shock waves generated by the WASP technique help breaking the sources of formation damage into smaller pieces; As a result, small particles can be carried to the surface.
