2020/2/14Carbonate deposits can possess structural complexity caused by widespread syn-sedimentary deformation. Carbonate deposits are unique in that they may become rocks during or shortly after deposition. This means that compared to other rocks of the same age, carbonates potentially experience a longer history of brittle deformation.

FEATURES OF CARBONATES AND RELATED RESERVOIR ISSUES
CARBONATE ROCKS Most of the world's giant fields produce hydrocarbons from carbonate reservoirs. Distinctive and unique aspects of carbonate rocks are their predominantly intrabasinal origin, their primary dependence on organic activities for their constituents
Chapter 22: A Classification of Metamorphic Rocks • Metamorphic rocks are classified on the basis of texture and composition (either mineralogical or chemical) • Unlike igneous rocks, which have been plagued by a proliferation of local and specific names,
Two carbonate classification systems are in common use today, one by R.L. Folk and the second by R.J. Dunham . The Dunham system is based on depositional texture (that is, the amount of matrix surrounding the grains at the time of deposition).

Technol.; (United States) The permeability, capillary properties, and m values of carbonate rocks are related to the particle size, amount of interparticle porosity, amount of separate vug porosity, and the
MODELING OF SEISMIC SIGNATURES OF CARBONATE ROCK TYPES
Carbonates are sedimentary rocks deposited typically in warm shallow waters. Unlike siliciclastics, carbonate rocks are biogenic in origin. They mainly consist of calcium carbonate and some fragments of algae, coral, skeletal remains and other marine
Petrophysical Parameters Estimated From Visual Descriptions of Carbonate Rocks: A Field Classification of Carbonate
A classification of carbonate porosity is proposed based on the data presented. This classification is intended to be used in the field or for routine laboratory description. Interparticle porosity is classified according to particle size and the dense or porous appearance of the interparticle area.
Rounded rock and rm.neral fragments, usually a finer matrix Angular rock and mineral fragments, usually in a finer sand Rounded quartz grains, well sorted. Color variable depending upon the type of cement. May contain sedimentary structures. Red: iron

carbonate rock type in the Dunham classification that is grain-supported. Allochems are in tangential contact but 10% exceed 2 mm in diameter; the interstitital mud consists of silt- and clay-sized mud of any composition (but is generally calcareous).
Carbonate rocks are made of particles (composed 50% carbonate minerals) embedded in a cement. Most carbonate rocks result from the accumulation of bioclasts created by calcareous organisms. Therefore carbonate rocks originate in area favoring biological activity i.e. in shallow and warm seas in areas with little to no siliciclastic input.

Limestone - In the Rock Classification Scheme, these are carbonate sedimentary rocks in which the dominant carbonate mineral is calcium carbonate in the form of calcite, aragonite and/or vaterite (vaterite is a metastable hexagonal form of calcium carbonate. It is
Sedimentological Characterization of Carbonate Rocks by
It considers the key textural (Dunham classification), mineralogical, compositional and fabric/sedimentary structure observations necessary to help evaluate and interpret carbonate rocks. Carbonate deposition is controlled by a wide range of internal and external factors, including the light, temperature, energy levels, salinity and nutrient availability.

Classification of Carbonate Rocks According to Depositional
Classification of Carbonate Rocks According to Depositional Textures. Three textural features seem especially useful in classifying those carbonate rocks that retain their depositional texture (1) Presence or absence of carbonate mud, which differentiates muddy carbonate from grainstone; (2) abundance of grains, which allows muddy carbonates to
Carbonate rock classification applied to brazilian sedimentary
A new classification of carbonate rocks is proposed seeking to cover the entire spectrum of their occurrence in Brazilian basins. Emphasis is given to those in oil exploration and production locations, especially since the discovery of giant oil fields in the so called Pre-Salt section.
