... Abstract It is well known that microbubbles play an important role in heavy oil reservoirs, where the presence of asphaltenes and other charged particles makes it easier to generate microbubbles. Only recently, however, microbubbles are being considered for rigorous analysis of primary...

... Abstract The term "Cold Production" refers to the use of operating techniques and specialized pumping equipment to aggressively produce heavy oil reservoirs. This encourages the associated production of large quantities of the unconsolidated reservoir sand creating a modified wellbore geometry...

The transient pressure responses above bubble point are anomalous recovery performance of heavy oil reservoirs successfully simulated; however, the pressure poses new challenges for transient pressure analysis. responses below bubble point cannot be reproduced using...

... Abstract Horizontal wells have been used successfully in Canada to recover oil from marginal heavy oil reservoirs in Saskatchewan and Alberta. These reservoirs are often poorly consolidated; recovery operations in these reservoirs are, therefore, usually susceptible to sand production...

... Abstract Efficient secondary and tertiary recovery a/heavy oil from thin reservoirs Isuch as chose in the Lloydminster area, remains an unsolved challenge to IORresearchers. The primary recovery from these heavy oil reservoirs is generallypoor (often < 5% OOIP) and waterflooding is rather...

... of operating freedom permits the operator to tailor the process parameters to suit the conditions of aarge variety of conventional, heavy oil and oil sand reservoirs. In this paper, simulation results will be resented to demonstrate how this may be achieved in a heavy oil reservoir. Introduction...

... Abstract The impetus for this work stems from the need to predict the field performance of a class of heavy oil reservoirs described as "foamy oil" reservoirs. Foamy oil reservoirs exhibit better than expected primary performance. Foamy oil reservoirs deliver greater primary recovery with less...

... Abstract Many heavy oil reservoirs in Alberta and Saskatchewan are unsuitable for thermal recovery methods. The present research was directed towards the development of non-thermal methods for such reservoirs. The main focus of this research was on the assessment of the recovery mechanisms...

... Abstract The capability to monitor the enhanced oil recovery processes in heavy oil reservoirs by active or passive seismic methods provides valuable tools for the reservoir engineer to manage the recovery process. The seismic wave velocities (compressional and shear wave) in reservoir...

... various conditions. Introduction Heavy oil reservoirs of Saskatchewan are characterized by thin pay (<10m), bottom water, high permeability, heterogeneity, high oil saturation and high viscosity oil (500 - 20,000 mPa-s at 20 °C). The primary and secondary processes recover less than nine percent...
