Thermal recovery is a common practice to commercial production of heavy oil reservoirs due to the exponential decrease of viscosity as temperature rises. Thus, techniques such as Cyclic Steam Stimulation (CSS) and Steam Assisted Gravity Drainage (SAGD) have played a fundamental role in the exploitation of this kind of reservoirs. Steam injection is used to increase oil mobility through the temperature increase, but it also changes the mechanical and petrophysical rock properties. The description of porosity behavior has a crucial role in planning any thermal recovery process to obtain better predictions of the medium's behavior and avoiding operational dangerous risks linked with caprock integrity and shearing failures.

GIGA developed a modified model to describe porosity-temperature relationship.

Heavy and extra heavy oil reservoirs are subjected to high temperatures during thermal recovery processes like SAG D and CSS. In-situ temperature state changes throughout these operations may generate variations in the mechanical properties or strength parameters of the rock such as Young and Bulk’s modulus, internal friction angle, cohesion and dilation angle. This paper presents results about the variation of the elastic modulus and mechanical properties, in both elastic and plastic region due to changes in temperature and effective confining stress for reconstituted samples of Colombian unconsolidated sands.
