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 ...

Discriminating cool-water from warm-water carbonates and their diagenetic environments using element geochemistry: the Oligocene Tikorangi Formation (Taranaki Basin) and the dolomite effect [PDF]

, 2004
Fields portrayed within bivariate element plots have been used to distinguish between carbonates formed in warm- (tropical) water and cool- (temperate) water depositional settings.

Introducing standardized field methods for fracture-focused surface process research [PDF]

Earth Surface Dynamics
Rock fractures are a key contributor to a broad array of Earth surface processes due to their direct control on rock strength as well as rock porosity and permeability.

A Geomechanical Study of the Mississippian Boone Formation [PDF]

, 2013
The Boone Formation in northwest Arkansas is a chert-limestone sequence analogous to the subsurface Mississippi Lime reservoir in parts of Oklahoma and Kansas. It has low permeability and produces via horizontal drilling and hydraulic fracturing.

True 3D Fracture Simulation with Geology-engineering Integration of Volume Modification in Jimsar Shale Oil

IOP Conference Series: Earth and Environmental Science, 2021
Abstract The main characteristics of Jimsar shale oil reservoir are of complex structure, strong heterogeneity and great difficulty in fracturing. It is mainly produced by volume fracturing technology, which is easy to form complex fracture networks. At present, the design and parameter optimization of fracturing scheme are not targeted,

Structural analysis of the eruptive fissures at Mount Etna (Italy)

Annals of Geophysics, 2011
Mount Etna produces frequent eruptions from its summit craters and from fissures on its flanks. The flank fissures trend approximately radially to the summit, and are mainly concentrated in three rift zones that are located on the NE, S and W flanks ...

Review of discrete fracture network characterization for geothermal energy extraction

Frontiers in Earth Science, 2023
Geothermal reservoirs are highly anisotropic and heterogeneous, and thus require a variety of structural geology, geomechanical, remote sensing, geophysical and hydraulic techniques to inform Discrete Fracture Network flow models.
