Pore Pressure Prediction in HPHT Wells

Abstract

Pore pressure prediction has been a vital concern to the oil and gas industry for many decades. Most petroleum provinces exhibit overpressures, and as the industry explores for deeper targets, encountering substantial overpressures are becoming more common. As deeper, hotter and more complex geology is drilled, the technical difficulties in predicting pressure, designing a well and safely drilling through complex overpressures. This specially caused by multiple mechanisms in “wildcat” settings have become extremely challenging and require innovative technique to be utilized. Several of the recently drilled wells encountered strongly over-pressured intervals which caused operational challenges and required finetuning of the pre-drill models based on the real time data.
