... Abstract Unconsolidated sands in heavy and extra-heavy oil fields in Mexico have significant potential that has not been fully evaluated yet. Thus, this paper examines petrophysics and geomechanical aspects with a view to estimating rock compressibility. This is important since determining...

... permitted to estimate the compressibility of the unconsolidated sandstone. Based on the evidence collected during the different tests, the conclusion is reached that during the processes of steam cyclic and steam continuous injection, a channel of high oil mobility was generated by the viscosity contrast...

... and Unconfined Compressive Strength (UCS). A better understanding of these parameters helps to minimize risks associated with drilling, stimulation, and wellbore stability problems. Geomechanical characterization is vital to understand fracture creation and propagation. Hydraulic fractures are more likely...

... is necessary for the economic assessment of CO 2 EOR, and for the evaluation of carbon sequestration capacity. We measured the porosity, the rock compressibility and the CO 2 sorption in sidewall core plugs taken from two wells drilled in the Wolfcamp shale. Computed tomography scanning technology was used...

...) reservoirs, it has not been possible to acquire representative cores and perform successful core plug tests. As a result, estimates of not only static parameters like porosity and saturation, but also dynamic parameters such as compressibility and permeability have been challenging. Historically this led...

Abstract The objective of this paper is to present a methodology using drill cuttings for making estimates of porosity, permeability and compressibility as a function of confining pressures in tight formations. An easy to use correlation is developed by comparing results from experimental work...

... line is obtained. However, when the single-phase gas compressibility factor ( Z ) is used, a deviation from the linear behavior is observed once the reservoir pressure falls below the gas dew-point. This methodology is applied in this study to unconventional shale gas condensate. Since there are three...

Abstract In naturally fractured reservoirs (NFRs), current analyses for quantifying reserves based on the material balance equation (MBE) assume that fractured reservoirs behave similar to homogeneous reservoirs, which implies that the fracture and matrix pore volume compressibilities are equal...
