Abstract -A typical seal rock in a Niger Delta reservoir was studied to describe its seal integrity. The brittleness index of the seal interval was estimated by first describing some elastic properties of the seal interval, Young’s modulus and Poisson’s ratio to be specific. These measures were estimated by measuring the p- and s-wave velocity from well logs obtained from a field in the Niger Delta. Comparing these velocities with depth showed a general trend of increasing velocity with depth. A mean brittleness index of 0.20 was estimated for the seal interval of one of the wells. This is indicative of a high seal integrity, as seal rocks with brittleness index less than 0.60 are considered to have good seal integrity.
