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.

Defining Flow Units in Dolomitized Carbonate-Ramp Reservoirs
SPE Annual Technical Conference and Exhibition, 1992ABSTRACT The problem of defining flow units in carbonate reservoirs has been investigated by integrated geological, petrophysical, and geostatistical outcrop studies. Results show that flow units (mappable intervals with similar petrophysical properties) can best be defined in terms of rock-fabric fades. Geostatistical analysis indicates

Structurally controlled hydrothermal dolomite reservoir facies: An overview
AAPG Bulletin, 2006Abstract Structurally controlled hydrothermal dolomite (HTD) reservoir facies and associated productive leached limestones are major hydrocarbon producers in North America and are receiving increased exploration attention globally.

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.

Fractures and Diagenesis, their Occurrence and Impact on Paleocene Dolomite Reservoir
Proceedings, 2013in Carbonate reservoirs. These two natural phenomena can be acting as positive reservoir contributors, in terms of reservoir efficiency and production, and also can be acting as negative contributors. In the last years, the carbonate reservoir remains the most challengeable reservoirs in exploration and developments where their reserves estimation and

Selected Characteristics of Limestone and Dolomite Reservoirs in the United States
AAPG Bulletin, 1985ABSTRACT Data from the United States Oil and Gas File (TOTL) developed by the University of Oklahoma, Norman, Oklahoma, are used to characterize the lithology, location (state and basin), geologic age, year of discovery, depth to top of pay, porosity, permeability, water saturation, volume of crude oil and nonassociated gas originally

Fault imaging in hydrothermal dolomite reservoirs: A case study
Geophysics, 2009Abstract Most 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.

Optimization of Chemical Flooding in a Mixed-Wet Dolomite Reservoir
SPE/DOE Symposium on Improved Oil Recovery, 2006Abstract Many pilot tests and several commercial field projects have been performed over the past few decades and have shown that surfactant/polymer and alkaline/surfactant/polymer floods can recovery high percentages of residual oil saturation.

Characterization of the dolomite reservoirs with the help of photoelectric index volume
SEG Technical Program Expanded Abstracts 2014, 2014Summary Carbonate sedimentary rocks that have been fractured, or dolomitized and laterally sealed by tight undolomitized limestone, are frequently seen to produce hydrocarbons. However, the differentiation between limestones and dolomites is a challenge. The purpose of this work is to describe a workflow for discriminating limestones and dolomites, and

A Proven Squeeze-Cementing Technique in a Dolomite Reservoir
Journal of Petroleum Technology, 1969Data on squeezed injection wells in a Grayburg-San Andres reservoir of West Texas indicate that a high final standing pressure is not a prerequisite for a successful squeeze. Profiles made a year after repair indicate that the wells have maintained the desired injectivity profile despite continued injection at fracturing pressure.
