| Abstract | ||
| Balsam Field is the most significant discovery in Qawasim Formation. The geological geophysicsal data interpretation reveals complicated horst block structure which is heavily faulted with north-south trending lineaments, the bright amplitude shows some correspondence to the reservoir extent and thickness, Qawasim Formation is divided into two units (Qawasim-I and Qawasim-II). The open-hole logs were good enough for proper formation evaluation. A Petrophysical work was done by calculating shale volume using single indicator (GR). Lithology determination was determined by using Mud-log description, cross plots for lithology indicators as density Vs porosity which indicates calcareous to highly calcareous sandstone especially on the top part of Qawasim-II pay. Vp/Vs crossplot was used to differentiate between different lithologies and fluid content (wet and gas sandstone and clay). The petrophysical evaluation proved 58 meters net pay in Qawasim Formation | ||
