Dolomitization and the causes of dolomitization dolomite reservoir

Chinese Journal of Geochemistry, 2012
This paper utilizes multi-methods, such as core observation, slice identification, isotope analysis, trace element analysis, fluid inclusion technique and so on, to study the causes of the dolomite in the Nanpu Sag and the origins of the dolomite reservoir.

Petrophysical Properties Estimation of Deep Dolomite Reservoir

82nd EAGE Annual Conference & Exhibition, 2021
Summary The dolomite reservoirs in China are generally deep buried and the prediction of petrophysical properties is very challenging for their low porosity and complex pore structures caused by the burial depth and diagenesis. The frame flexibility factor can be used as proxy for pore structure quantification such as quantitative carbonate pore type ...

Dolomite reservoirs: porosity evolution and reservoir characteristics

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1995
ABSTRACT 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 ...

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 ...

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,

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.

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

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 ...

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.

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.

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 ...
