...-assisted gravity drainage Simulation steam pipeline pressure gradient heat transfer coefficient Introduction Steam injection is a special method of recovery applied generally for very viscous oil reservoirs. This method consists of injecting heat to reduce viscosity and, this way, increase...

... with overburdens of more than 30m, the inductive method has been found to be the most reasonable in terms of technical and economical feasibility. To evaluate the lifetime efficiency, a reservoir simulator has been coupled to a finite element program, in order to implement the effects of alternating current losses...

... Abstract We have modeled the warm-up phase of a SAGD project using a coupled reservoir simulator and stress model. We matched the injection pressure by adjusting the reservoir permeability. A fair match between data and model was obtained. Micro-seismic monitoring indicated localized injection...

... ). As the solvent condenses with the steam along the boundary of the gas chamber, it dissolves in the bitumen thereby reducing its viscosity and increasing oil recovery rates. An experiment and simulations were performed to investigate ES-SAGD at a low operating pressure of 1,500 kPa. Abstract SAGD...

.... A computer simulation assessing the stress in the cement sheath is presented. Flexible cement systems can be designed so that the cement sheath can withstand the expected stresses during the life of the well. Preventing cement breakdown can be achieved by improving the installation practices...

... , unconventional crudes need to have appropriate design considerations applied into the design simulation. Designers should "track down" all relevant data to improve the chances of realistically representing the expected operating situation from the design choices made. The data provided in this paper can be used...

.... If classic rules could be applied for casing design, pioneering rules should be considered to design cement sheath. This paper presents a singular methodology to design cement sheath long term integrity in very shallow conditions. First, stresses in the field are evaluated with a rock mechanics simulation...

... Abstract In the recent years several SAGD projects have been initiated for the recovery of heavy oil and bitumen. Every operator is coming across new learning almost every day, although most of this information is proprietary. This paper presents a general discussion, supported by simulation...
