determination of porosity, permeability, and pore volume compressibility of reservoir rocks and those variations with effective stress changes are of great interest in petroleum engineering. this paper has studied the influence of pore types of carbonate reservoir rocks on pore volume compressibility as well as klinkenberg permeability and porosity at different stress values. in the current stu...

The petroleum industry requires the best materials to reverse the rock wettability to water-wet state which give significantly improved oil recovery.Nanoparticles are suggested as enhanced oil recovery potential agents to decrease viscosity and alter the wettability of reservoir towards more water-wet. This study provides new insights into CuO nanoparticles effects on wett...

Clinically significant delayed absorption after lithium overdose has been reported previously without adequate explanation. We have studied two patients after they took massive intentional lithium overdoses. The first patient presented shortly after ingesting 74 g of lithium carbonate. Pharmacokinetic analysis with a multicompartmental model of 29 serum lithium concentrations during 300 h (incl...

RESULTS Drilled four wells based on the model, successfully predicting the type and thickness of reservoir facies, enabling the operator to pursue optimal field development strategies with higher confidence in the distribution and connectivity of critical flow units. Modeling reservoir architecture with limited data After successfully developing Cretaceous reservoirs in several northern Kuwait ...

The article considers the issue of reducing the influence of clayless mud components on the filtration parameters of the reservoir. In the composition of such solutions, calcium carbonate of various fractions is often added as a weighting and colmatizing additive. It is generally accepted that weighting bridging agents are sufficiently inert substances and their addition does not affect the rhe...

Flow unit and reservoir rock type identification in carbonates are difficult due to the intricacy of pore networks caused by facies changes diagenetic processes. On other hand, these classifications necessary for understanding a predicting its production performance face any activity. The current study focuses on flow classification Mishrif Iraq's southeast is based data from five wells that pe...
