I present an idealized physical model of steamflood fluid-flow and make rock physics predictions of seismic impedance changes that might be observable in 3-D surface seismic monitoring data. Four distinct fluid-flow phases are considered. Closest to the steam injection well, a small hot steam zone should be very visible in seismic data due to a predicted 30% decrease in P-wave velocity (Vp) com...

Abstract The technical, environmental and economic performances of a steam flood are partly influenced by the operating temperature (pressure). However, definition procedure for determining optimum still debatable. Employing combination analytic modelling numerical simulations, this paper investigates existence (or otherwise) an injection T opt saturated-steam floods. Considering maximization p...

Based on a recently published theoretical model, in this work we experimentally studied the problem of gravity water drainage due to continuous steam injection into an elliptical porous chamber made glass beads and embedded metallic, quasi-2D, massive cold slab. This configuration mimics process condensation for given time period during growth stage steam-assisted (SAGD) process, method used re...

Steam distillation as one of the important mechanisms has a great role in oil recovery in thermal methods and so it is important to simulate this process experimentally and theoretically. In this work, the simulation of steam distillation is performed on sixteen sets of crude oil data found in the literature. Artificial intelligence (AI) tools such as artificial neural network (ANN) and also ad...

The most widely applied methods to unlock heavy oil and natural bitumen resources in the world are still based on steam injection techniques. Improving efficiency of hydrothermal processes poses a great challenge. co-injection various additives is practiced lower steam-to-oil ratio (SOR), viscosity alteration improve properties. Organic solvents, non-condensable gases, air surfactants preferred...

Thermal recovery techniques including Fast-SAGD process increases the production efciency of heavy oil reservoirs. Effective parameters in this study included injection and production rates, height of the injection, production, and offset wells, production and injection cycles, and pressure of the offset wells. In this study, optimization studies were performed. The objective function was defned a...
