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 ...

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.

Structurally controlled hydrothermal dolomite reservoir facies: An overview: Discussion
AAPG Bulletin, 2007One of the issues of the AAPG Bulletin (v. 90, no. 11) was concerned with “hydrothermal dolomite reservoirs,” specifically “hydrothermal dolomite fields” (Davies and Smith, 2006). The term “hydrothermal dolomite” is confusing and meaningless (Machel and Lonnee, 2002). To study the origin of dolomite and its hydrothermal depositional setting, I examined

Reservoir properties of the Raminger Dolomite
This thesis characterizes the reservoir properties of Middle Triassic dolostomite to evaluate its potential for deep geothermal use, dolomites belong to the Raming Formation of the Göller Nappe exposed on the Hoher Lindkogel near Baden. The analysed outcrops are regarded analogues of hydrothermal reservoirs in the adjacent Vienna Basin.openaire +1 more source
Sedimentary Geology, 1986
Abstract Reservoirs of commercial gasfields in eastern Sichuan, China, occur in Middle Carboniferous dolomite. Porous reservoir rocks in this dolomite are bounded by an upper disconformity and were deposited in tidal flats. Two types of diagenetic histories are suggested.
