Dolomite reservoirs: porosity evolution and reservoir characteristics

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1995
Systematic analyses of the published record of dolomite reservoirs worldwide reveal that the majority of hydrocarbon-producing dolomite reservoirs occurs in (1) peritidal-dominated carbonate, (2) subtidal carbonate associated with evaporitic tidal flat/lagoon, (3) subtidal carbonate associated with basinal evaporite, and (4) nonevaporitic carbonate ...

Identifying Reservoir Pathways in a Fractured Dolomitic Heavy Oil Reservoir

SPE Improved Oil Recovery Symposium, 2010
Abstract The Issaran field, situated in the Egyptian Eastern Desert, is one of the few heavy oil fractured carbonate reservoirs in the world (Refs.1 to 3). Oil production and recovery from such fractured heavy oil carbonate reservoirs is generally lower than conventional reservoirs, with primary recovery being as low as 1% in some cases,

Geosteering in a Complex Dolomitic Reservoir

SPE/IADC Middle East Drilling Technology Conference, 2001
Abstract This paper presents the key of success for the development of a complex prospect, the Sarr dolomitic reservoir in the Kharir field, located onshore Yemen. The drilling of horizontal wells was considered to limit the early water encroachment observed on vertical producers and to improve both the oil production and the final ...

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 ...
