Compressive strength of rocks - PetroWiki

Jun 04, 2015· The high-porosity (33%) sandstone (Fig. 4a) has a low "crush" strength of about 55 MPa. With a lower porosity of 19%, Berea sandstone has a much higher strength of 440 MPa (Fig. 4b). Notice that in both Figs. 4a and 4b, permanent deformation remains even after the stress is released. This hysteresis demonstrates the damage to the matrix ...

Impact of Iron Minerals in Promoting Wettability ...

Different sandstone cores were used, such as Berea (BSS), Bandera (BND), Kentucky (KSS), and Scioto (SCS) sandstone rocks with different clay minerals. ζ-potential measurements were used to investigate the surface charge of the different clays and different sandstone rocks with different fluids.

The aforementioned problem becomes more sensitive in a low permeability formation when the adsorption is much higher than the desorption. This study, therefore, investigated the surfactant desorption isotherm using sodium dodecylbenzene sulfonate (SDBS) as a surfactant and tight Berea sandstone as adsorbent.

Adsorption of Crude Oil Components onto Carbonate and ...

Mar 17, 2021· The processes of establishing and altering reservoir wettability are still subjects of discussion due to the complexity of the underlying crude oil–brine–rock interactions. This study was aimed at investigating the interrelationship between acidic and basic crude oil components and wetting tendencies on core samples of various mineralogies. Core flooding tests with light crude oils were ...

Pore Structure Characterization of Eocene Low-Permeability ...

Apr 23, 2021· It is shown that the recent capillary pressure measurements of S. C. Melrose (1988) also imply a fractal structure. Melrose measured the capillary pressure (P) of Berea sandstone at low saturations (S) of water. His data cannot be rationalized in terms of …

Relative permeability - PetroWiki

Jan 19, 2016· Relative permeability behavior. Figs. 1 and 2 show typical behavior for a gas/oil system. The semilog scale of Fig. 2 is convenient for reading the relative permeabilities less than 0.05. Although the curves are labeled "gas" and "oil" in these figures, the phase identity of a curve can be deduced without the labels.

Wettability - an overview | ScienceDirect Topics

Wettability is defined as the tendency of one fluid to spread on or adhere to a solid surface in the presence of other immiscible fluids. The concept of wettability is illustrated in Figure 4-1.Small drops of three liquids—mercury, oil, and water—are placed on a clean glass plate. The three droplets are then observed from one side as illustrated in Figure 4-1.

Permeability | Fundamentals of Fluid Flow in Porous Media

Oct 25, 2016· Fundamentals of Fluid Flow in Porous Media Chapter 2 Permeability Permeability is a property of the porous medium that measures the capacity and ability of the formation to transmit fluids. The rock permeability, k, is a very important rock property because it controls the directional movement and the flow rate of the reservoir fluids […]
