Evaluation of heat flow anomalies and hydrocarbon accumulation in IB field, Malaysia

Studies of heat flow anomalies have been conducted in the hydrocarbon field to determine types of heat flow mechanisms namely conduction, radiation and convection. A heat flow anomaly can be detected if the calculated value varies in huge difference compared to the normal heat flow in that particula...
