Definition - What does Core Analysis mean?
Core Analysis is the analysis carried out to determine the accurate details of the permeability, porosity and other characteristics of a well. It is beneficial as core analysts can easily evaluate the details of well or reservoir thus they can optimize production. Moreover, the analysts can figure out specific issues of each product. It is important as the production of oil and gas highly depends upon the key properties of a reservoir rock. Besides, it is also determines the vertical and lateral heterogeneity of the rocks in shale reservoirs.
Petropedia explains Core Analysis
Core analysis not only defines porosity and permeability, but also unearths the fluid saturation and grain density of the rocks. The data is used by several engineers, geologists, and drillers to understand the potential productivity and the conditions of a well. Special instruments are used to determine the characteristics, such as porosity is measured by a porosimeter and permeability is measured by core plug or permeameter. Moreover, finer details are obtained by using electron microscopy and X-ray diffraction. The information is used to make well and completion designs and to describe reservoir production.
