Solubility Features of Dolomite Reservoirs in Hydrochloric Acid at Low Reservoir Temperatures

Saint Petersburg 2020, 2020
Summary Low-temperature carbonate deposits are typical for the territories of western Siberia. In conditions of low permeability, acid treatment of wells is a widely used method of stimulating the reservoir, but low reservoir temperatures have a significant impact on the effectiveness of the treatment.

Defining Flow Units in Dolomitized Carbonate-Ramp Reservoirs

SPE Annual Technical Conference and Exhibition, 1992
ABSTRACT 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

Dolomitization, Dolomite Distribution, Reservoir Rocks: ABSTRACT

AAPG Bulletin, 1970
Approximately 80% of the hydrocarbon reserves in carbonate rocks in North America are found in rock that is essentially pure dolomite. In many reservoirs the field limits are determined by the distribution of dolomite, because the dolomitization process is conducive to the production of a favorable reservoir rock.

Rock physics and reservoir characterization of a calcitic-dolomitic sandstone reservoir

First Break, 2011
H. Morris, B. Hardy, E. Efthymiou and T. Kearney highlight the steps used to take us from a petrophysics to reservoir model introducing methods to improve the data quality via seismic data conditioning and highlighting some of the benefits of using a sequential Gaussian inversion over more conventional deconvolution style inversion methods.

Structurally controlled hydrothermal dolomite reservoir facies: An overview

AAPG Bulletin, 2006
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. They include multiple trends in the Ordovician (locally, Silurian and Devonian) of the Michigan, Appalachian, and other basins of ...

Dolomite and dolomitization of the Permian Khuff-C reservoir in Ghawar field, Saudi ArabiaSea

AAPG Bulletin, 2017
ABSTRACT The Permian Khuff-C reservoir in Saudi Arabia is known for its lateral and vertical heterogeneity caused mainly by dolomitization. Detailed petrographic analysis of 600 thin sections, from six cored wells, revealed three main replacive dolomite fabrics: (1) fabric-preserving mimetic (FPM), (2) fabric-preserving nonmimetic (FPNM), and (3 ...

Analysis of dolomite reservoir characteristics of Lower Permian Maokou Formation and dolomite origins in Chuanzhong Area

Journal of Petroleum Science and Engineering, 2022
Abstract Dolomite of Lower Permian Maokou Formation has a strong heterogeneous formation in-plane and vertical in Chuanzhong Area. Its formation mechanism is not yet fully understood. Thus, this study focuses on the Maokou Formation core and conducts thin section analysis, isotope analysis, cathodoluminescence, and data analysis of fluid inclusion ...

Predicting Reservoir Properties in Dolomites

1997
ABSTRACT 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, 2019
Summary 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, 2015
Abstract 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.
