Abstract
BG Group entered Tanzania in June 2010 attracted by the possibility of large frontier exploration plays and sizeable licence blocks covering deep to ultra-deep water close to several recent discoveries.
This paper focuses on the exploration activity that has been conducted in offshore Tanzania’s blocks 1 and 4 between 2010 and 2015. The paper will provide examples of the diverse trap types that have been tested, the range of geological ages penetrated with the drill bit and different geological facies identified either through drilling or seismic observation. Emphasis will also be placed on some of the challenges encountered and technological enablers that have been deployed to safely deliver the activities described in a remarkably short timeframe of five years. This exploration activity has delivered sixteen wells with a 100% success rate of encountering hydrocarbons. The activities described have transformed the Tanzanian petroleum story from a “hot spot” of frontier exploration potential to a proven hydrocarbon province holding several TCF of gas spread across multiple plays.
