Hall plot analysis for horizontal well injectivity
… the 1960s, is a widely-used tool for analyzing injectivity. Over the past decades, industry has been modifying the Hall plot method for applications in various scenarios such as formation damage and/or stimulation diagnosis, polymer injection, and gas injection. It has proved to be a simple, …

Effect of halite (NaCl) on sandstone permeability and well injectivity during CO2 storage in saline aquifers
… there is a substantial concern about the near well bore formation dry out as a result salt precipitation in the form of halite (NaCl). The focus was on one of the important physical mechanisms of CO2 injection into deep saline aquifers. The salt (mainly halite) will eventually fully saturate …

Particle Detachment in Single-Phase and Two-Phase Flows in Porous Media
… used for reliable laboratory-based prediction of well injectivity decline. The results show that fines migration during low-salinity water injection results in significant well injectivity impairment. The thesis also investigates low-salinity water slug injection followed by a high-salinity chase …

Simulation of stress dependent fluid flow in naturally fractured reservoirs
… fracture connectivity, rock deformation, well injectivity and productivity, recovery and even distribution of fluid inside reservoir as a result of rock deformation. The case studies have proven the method to be very efficient in terms computational resources. It also eliminates most of …

Injection Impairment by Suspended Solids: Well Models, Filtration Parameters, and Models’ Validation with 3-D Injection Experiments
… resulting in reduced permeability and loss of injectivity. Water injection, without solids suspension, at high velocity generates a loss of injectivity as a non-Darcy flow effect. The compounding impacts of high injection fluid velocity with suspended solids are expected to produce more severe …

Numerical Simulation and Optimization of CO2 Sequestration in Saline Aquifers
… the detailed mechanisms of GCS are not well-understood. As a result, there remain many uncertainties in determining the sequestration capacity of the formation/reservoir and the safety of sequestered CO2 due to leakage. These uncertainties arise due to lack of information about the …
