Structure and fracture characterization of the Jizan group: Implications for subsurface CO2 basalt mineralization

Frontiers in Earth Science, 2023
The coastal region of southwest Saudi Arabia contains a thick sequence of Late Oligocene basalts in the Jizan Group, which accumulated along the continental rift that preceded the opening of the Red Sea. These basalts are targeted for the disposal of CO2

Simulating spatial and temporal evolution of multiple wing cracks around faults in crystalline basement rocks [PDF]

, 2007
Fault zones are structurally highly spatially heterogeneous and hence extremely complex. Observations of fluid flow through fault zones over several scales show that this structural complexity is reflected in the hydrogeological properties of faults ...

Estimation of the Fracturing Parameters and Reservoir Permeability Using Diagnostic Fracturing Injection Test

Iraqi Geological Journal, 2023
The term "tight reservoir" is commonly used to refer to reservoirs with low permeability. Tight oil reservoirs have caused worry owing to its considerable influence upon oil output throughout the petroleum sector.

Simulation of subseismic joint and fault networks using a heuristic mechanical model [PDF]

, 2017
Flow simulations of fractured and faulted reservoirs require representation of subseismic structures about which subsurface data are limited. We describe a method for simulating fracture growth that is mechanically based but heuristic, allowing for ...

Transport model for shale gas well leakage through the surrounding fractured zones of a longwall mine

International Journal of Mining Science and Technology, 2020
The environmental risks associated with casing deformation in unconventional (shale) gas wells positioned in abutment pillars of longwall mines is a concern to many in the mining and gas well industry.

Productivity Prediction of Fractured-Vuggy Reservoirs under Time-Varied Flow Rates and Bottom Hole Flow Pressures

Geofluids, 2022
Fracture-vuggy oil reservoirs contain micrometer-sized dissolved secondary pores, fractures, and meter-sized karst caves. Generally, the researches on the flow mechanism of fractured-vuggy reservoirs are based on the assumption of karst cave-fracture ...

The Cyrilka Cave-the longest crevice-type cave in Czechia: structural controls, genesis, and age [PDF]

, 2018
The Cyrilka Cave is the second longest pseudokarst cave and the longest crevice-type cave in Czechia. Developed within the headscarp area of a deep-seated landslide, the cave became a focus of scientific research in recent years when new passages were ...
