Pressure Study of the North Sea Central Graben

 

Assess and reduce risk associated with hydrocarbon prospectivity, reservoir connectivity and entrapment

Utilise key information to decide whether to acquire or drop acreage in this high pressure, high temperature (HP/HT) region

With increased focus on drilling in the Central North Sea following recent discoveries and revitalised licencing activity, GeoPressure Technology, the UK's leading pressure experts and IHS Energy, developers of a unique Formation Pressure database, have combined in a joint venture to examine the distribution and impact of overpressure on the North Sea Central Graben petroleum system.

The benefits to a company with exploration, development and/or production interests in the Central North Sea Graben include:

  • Reduced Risk
  • Associated time and cost savings
  • Potential reserves upside
  • Improved understanding of the regional pressure regime
  • Reliable and convenient information

 

This significant new Study utilising over 1200 wells and the high quality data used in its compilation provide a comprehensive and authoritative picture of formation pressure distribution, and its causes within the Central Graben, giving valuable calibration to in-house pressure interpretations.
