Predicting Reservoir Properties in Dolomites
1997ABSTRACT Completely dolomitized Upper Devonian Leduc buildups at depths >4000 m have higher porosities and permeabilities than adjacent limestone buildups; dolostones are more resistant to pressure solution and tend to retain their porosity during burial.

Algae Beach Dolomite Reservoir Prediction in Sichuan Basin, China
81st EAGE Conference and Exhibition 2019, 2019Summary The algae beach dolomite reservoir, with great exploration potential, is widespread developed in the study area, which is located in the northwest of Sichuan Basin. The reservoir of Triassic Leikoupo formation is strong heterogeneity, and the lateral distribution is discontinuous.

Stimulating High-Temperature Dolomitic Limestone Reservoirs with Chelant Fluids
SPE European Formation Damage Conference and Exhibition, 2015Abstract Oil production in southern Mexico is mainly from deep (>16,000 ft) high-temperature (> 300°F), naturally fissured dolomitic limestone reservoirs with clays present. With increasing depth, the dolomitization increases and the porosity and permeability decrease.

Fault imaging in hydrothermal dolomite reservoirs: A case study
GEOPHYSICS, 2009Most hydrocarbon fields found within the Ordovician Trenton and Black River Groups of the eastern United States and eastern Canada are associated with basement-related faults. These faults are best imaged by 3D seismic technology. Because of environmental conditions, seismic data often are contaminated by noise that masks fault terminations and ...

Many subsurface carbonate reservoirs contain evidence for dolomitization associated with tectonic fluid circulation that has significant impact on reservoir properties. However, reservoir geometry and internal reservoir characteristics (diagenetic phases, porosity types, heterogeneity of pore networks) remain often poorly understood.

Petroleum Reservoirs in Silurian Dolomite of Western Illinois: ABSTRACT
AAPG Bulletin, 1985The basal Silurian Alexandrian carbonates, sandwiched between the Ordovician-Silurian and Silurian-Devonian unconformities, have produced more than 3 million bbl of oil from the Buckhorn East and Brooklyn fields on the western margin of Illinois. These fields are shallow (450-670 ft), remote from the most-productive portion of the Illinois basin, and ...

Energy & Fuels, 2019
Shale oil has been found in the argillaceous dolomite reservoir of the Paleogene Xingouzui Formation in the Jianghan Basin. However, the shale oil storage mechanism in these rocks remains unclear, considering that increasing attention has been paid to shales instead of argillaceous dolomites.

Ordovician Red River Dolomite Reservoirs, Killdeer Field, North Dakota
1985Killdeer Field was discovered by Amoco Production Co. in 1976, when the #1 Grant Carlson well drill-stem tested more than 4000 feet (1219 m) of oil from the Ordovician Red River Formation. Located in the Williston Basin of west-central North Dakota (T-145-N, R-94-W, Dunn County), U.S.A., the field has produced oil from two zones in the Red River (Fig ...

Reservoir quality, textural evolution, and origin of fault-associated dolomites
AAPG Bulletin, 2007Fault-associated dolomitized carbonates are proven hydrocarbon reservoirs in the subsurface; yet their origins and spatial variability in reservoir quality are poorly understood. Fault-associated dolomitization has affected a 4–8-km (2.5–5-mi)-wide strip of inner-platform carbonates of the Oligocene–Miocene Taballar Limestone, exposed onshore ...

Hydrothermal Dolomite Reservoir Analogue Study - the Cantabrian Case Study
Proceedings, 2011In the platform to slope Cretaceous carbonate succession of the Cantabrian Mountains (N-Spain), sub-seismic fault restricted dolomite bodies predominate while in the platform interior, massive stratabound bodies, several square kilometre in size, occur.
