Abstract
Naturally Fractured Reservoirs (NFRs) are found indifferent parts of the world
throughout all geological eras in different types of lithologies. They are formed when
rock masses are naturally fractured due to response for geological stresses and diagenesis
process. There is no specific technique to identify & characterize NFRs. However, direct
methods such as core analysis, core scale pressure transient, impression packers, down
hole cameras and drill cuttings are used while indirect methods employ: well log
evaluation, drilling history, well test evaluation, manipulation of rock property data &
remote sensing. Data from these with rock property and fluid data are used to determine
the permeability and characterize NFRs at different scales.
Due to the presence of natural fractures and matrix porosity systems and probably
with multiphase fluids, NFRs are more technically and economically challenging than
the single porosity matrix reservoirs as fracture properties: fracture width, connectivity,
spacing, morphology, degree of mineral deposition in fractures as well interaction
between matrix and fractures control the performance of NFRs.Though classification
depends on the objectives of the study, there are generally three types NFRs based on
the contribution of fluid from the matrix & fracture porosity: Type A-high storage
capacity in the matrix and low storage in fractures, Type B-about equal storage capacity
in matrix and fractures and Type C-all storage capacity is in fractures.
Though, previously failed to attract much attention of the petroleum Industry, they
witnessed their potentiality when they closely studied. There are different currently
producing NFRs that exemplify the hydrocarbon potentiality of these unconventional
reservoirs. This project has clearly & briefly described the fractured Cambrian sandstone
reservoir of the giant Hassi Messaoud oil field of Algeria.
