Tuning the salinity and concentration of potential-determining ions, such as Mg2+, Ca2+, and SO4
2−, could alter the wettability
toward a more water-wet state. The rate of alteration in carbonate rock wettability is a ...

The significant loss of surfactants during reservoir flooding is a
challenge in oil field operations. The presence of clay minerals affects the
surfactant performance, resulting in surfactant losses. This is because ...
In this work, a hydrogel system was produced via radical polymerization of N,N‐dimethylacrylamide and 2‐acrylamido‐2‐methylpropanesulfonic acid in the presence of N,N‐methylenebis‐acrylamide as a crosslinker and ammonium ...
In cryogenic fracturing, a rock surface exposed to cryogenic fluids undergoes a large thermal gradient, and the resultant local tensile stress overcomes rock strength and initiates fractures. This study investigates the ...
3D modelling of geological domains is an essential part of orebody modelling and
resource classification. Conventionally, one applies a wireframing technique, which, in
practice, is quite laborious. An automatic approach ...
In multivariate geostatistics, it is common to have different types of complexities between
variables of interest. In this context, an inequality constraint is an example of complex
bivariate relationships. Unfortunately, ...

Stuck pipes are one of the most serious drilling problems, stuck pipes can cost the oil industry hundreds of millions of dollars per year. One way to avoid the risk of a stuck pipe is to predict the condition of a stuck ...
Background: Fabry disease (FD, OMIM #301500) is a rare, progressive, X-linked inherited, genetic disease due to the functional deficiency of lysosomal α-galactosidase (α-GAL) that leads to the accumulation of glycosphingolipids ...

A hybrid enhanced oil recovery (EOR) method by combining low salinity water (LSW) and low salinity surfactant (LSS) flooding techniques was designed. Different
experiments were done to screen the Caspian seawater (SW) ...
Assessing the stability of stopes is essen tial in open stope mine design as unstable hangingwalls
and footwalls lead to sloughing, unplanned stope
dilution, and safety concerns compromising the prof itability of the ...

The flow of blasted ore during mining of moderately dipping medium-thick orebodies is a challenge. Selecting a suitable mining system for such ore bodies is difficult. This paper proposes a diamond layout sublevel open ...
Accurate determination of rock mass deformation modulus is very important in rock engineering projects. The plate loading test (PLT) is a method that is generally used in dam construction projects to determine rock mass ...
The results of many previous studies on low salinity/controlled ions water (CIW) flooding suggest that future laboratory and modeling investigations are required to comprehensively understand and interpret the achieved ...

Different oil displacement experiments conducted on sandstone and carbonate samples show that low salinity water (LSW) injection can reduce the residual oil saturation (ROS). Recently, surfactant flooding (SF) in combination ...
Loss of drilling fluid is a common problem during the drilling of wells and it restricts the appropriate functionality of muds. Drilling fluid loss significantly increases drilling costs and non-productive time as well as ...
The salt formation creeping can signifcantly afect the casing stability, because of the changes in mechanical and geome chanical parameters. The creeping of Gachsaran salty formation in the south part of Iran has infuences ...

The use of engineered water (EW) nanofluid flooding in carbonates is a new enhanced oil recovery (EOR) hybrid technique that has yet to be extensively investigated. In this research, we investigated the combined effects ...
Hierarchical or cascade resource estimation is a very common practice when building a
geological block model in metalliferous deposits. One option for this is to model the geological
domains by indicator kriging and then ...
