Foamy oil is commonly observed phenomenon during cold primary production of heavy oil reservoirs. Along with the pressure depletion, a type of anomalous flow of oil and gas phases appears when pressure is lower than the thermodynamic saturation pressure. Foamy oil is believed to bring positive effects to heavy oil recovery and well productivity by promoting favored fluid properties and oil swelling. The proposed study focuses on the description of the complex phase behavior of foamy oil systems to examine equilibrium versus non-equilibrium behaviour at different depressurization rates.
Models quantifying the grade and tonnage of mineral deposits form the basis of important and costly decisions for planning, optimization and extraction of a natural resource. Models are initially generated from sparse exploration sampling; however, information is continuously collected until resource extraction. Predicted values that reconcile well with true values following extraction instill confidence in the production forecasts.
This project is aimed for an accurate and highly convenient methodology to visually investigate the multiphase flow behavior, foamy oil stability and solvent mass transfer in solvent injection processes.
This project is to perform systematic studies to better understand key recovery mechanisms of mixture solvent CSI process and provide fundamental parameters for field-scaled prediction. For mass transfer, a methodology of measuring diffusion coefficients for multiple components simultaneously dissolving into heavy oil systems under bulk volume and porous medium conditions will be established. For foamy oil flow, its properties of non-equilibrium will be investigated by PVT measurement and depletion tests, respectively.
This has been a proposal for myself, Stephen Collins, to participate in the FASESP – BG Brazil Research Centre for Gas Innovation project. If awarded via the Mitacs Globalink program, I will be presented the opportunity to work alongside the research staff of The University of Sao Paulo, as well as members of other academic institutions and industry. The project itself has been in various stages of planning for the past several years: and was approved after being peer-reviewed by an international committee.
The proposed research is a multi-disciplinary project, which aims at improving existing theories and developing innovative technologies to unlock Canadas oil and gas resources in a more sustainable way. Theoretical models derived from physics and mathematics are to be examined with real data, and new approaches will be developed to face the technical challenges. Mentorship and realistic field feedbacks from the industry are of great importance to the interns research work.
The Grosmont Formation contains about 400 billion barrels of resource and is a huge prize for Alberta and Canada. Laricina Energy is at the forefront of unlocking this resource with its Saleski carbonate pilot. The Grosmont mainly consists of dolomite and if acid is added to the formation, the reservoir rock dissolves and its permeability can be enhanced. It remains unclear whether acid stimulation is acting as a wellbore cleaning technology or whether it is acting as an element of the recovery process itself since acid reacts with the carbonate rock to generate carbon dioxide.
Permeation of CO2 gas through the inner layer in multi-layer fiber reinforced pipes (FRPs) destructively reduces pipedurability. FRPs generally consist of three or more layers of polymer and reinforcing fibers. Gas permeation thoroughthe polymer layer and its accumulation in reinforcing layer leads to pipe failure during depressurizing cycles. Using claynano-platelet can lead to decrease gas permeability in polymer layers. Good dispersion and good adhesion between clay nano-layers and polymer are key features for optimization of gas permeability. This study will focus on optimizing
Methanobiofiltration (MBF) is a new technology for the treatment of waste methane gas using a biological process, thus contributing to the reduction of the environmental impacts of current energy technologies. The lack of a complete technology package needed for various industry sectors has hindered its large-scale application in Alberta.
