Ten challenges in naturally fractured carbonates

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.

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.

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).

Carbonates Rocks

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.

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.
