PreVue Real-Time Geopressure Service

The PreVue service provides prediction and real-time monitoring of pore pressure and wellbore stability at the wellsite, using LWD, MWD, and gas data.

No matter where you drill, the potential for encountering abnormal pressure is always present and can sometimes result in kicks, mud losses, and other well control problems. Significantly abnormal pore pressure could lead to loss of the entire well, together with substantial destruction of life and property. The PreVue service plays a significant role in reducing these risks.

Comprehensive analysis

The service

• uses comprehensive, location-specific analyses in real time to calculate and analyze normal hydrostatic, overburden, and pore pressure; and fracture gradients
• incorporates seismic analysis to create a complete interpretation of the pore pressure regime likely to be encountered
• uses discrete pressure compartment analyses to better understand pore pressure envelope shifts at bedding interfaces, in particular for sand and shale.

The PreVue service is applicable in all environments including wildcat exploration wells; deep gas wells; wells with narrow mud weight windows; wells drilled in basins with high tectonic stresses; high-pressure, high-temperature (HPHT) wells; and non-vertical and extended-reach drilling (ERD) wells.

Daily geopressure reports are delivered to key decision makers at the wellsite and in your office. PreVue specialists become an integral part of the wellsite operations and the decision-making process related to geopressure issues, providing proactive and actionable geopressure expertise.
