Investigation into Brinell hardness test applied to rocks

Abstract

Literature review information about the knowledge of the rock strength with particular reference to hardness has been utilized. The Brinell hardness test is a simple and inexpensive estimation of the strength properties of a formation, thus reducing the high cost of extensive laboratory rock testing program. These tests were carried out on rock samples taken from the Hassi Messaoud site investigation (wells OMN602 and OMN402) at different depth ranging from 1,900m to 2,900m. Comprehensive lists of the known tests were established. A description of the site from where the samples were obtained is discussed. The methods and procedure of the laboratory tests are also presented. It is also shown there exists a useful correlation between Brinell hardness and the strength properties of the rock.
