Geopressure Data & Studies

Drill cost-effectively with standardized and validated well geopressure data

Can you afford to drill a well without understanding the subsurface pressure regimes?

In some highly pressured regions more than 90 percent of unpredicted drilling downtime is due to overpressure, with annual costs to industry estimated at nearly $8B. The IHS Markit Geopressure Database is one of the most comprehensive, accessible and up-to-date geopressure databases in the world. It provides immediate and accurate subsurface data so you can make informed decisions and stay competitive.

Key benefits of this product include:

  • 28 man-years of data sourcing, processing and expert re-interpretation
  • Reinterpretation and quality control of formation test pressures by in-house experts
  • Data standardized allowing comparison of wells
  • Standardization of pressure units and hole temperature corrections
  • Sourcing and cataloging of additional down-hole, pressure related events
  • Data centrally located within a single database, accessible by multiple users
  • Equates to an investment of $1.87M assuming a flat rate of $75K per year


The database is created and delivered as a Microsoft™ Access file, which includes functionality to export into Excel or ASCII formats

The database includes the following attributes:
  • Well header
  • Formation pressure (wireline, while drilling, dst. kick event)
  • Fracture pressure (integrity, leak off, lost circulation)
  • Drilling mud
  • Temperature
  • Formation water salinities
  • Gas events
  • Drilling comments
  • Casing and liner
  • Formation tops

Coverage (Updated September, 2014)

Pressure records are created using public well data sourced via government channels, ie. DECC, NPD, Bureau of Ocean Energy Management, Regulation and Enforcement or through data exchange agreements with oil companies.

Within the database, wells are classified based upon their content, such that:

  • Class 'A' well - contains formation pressures derived from WFT/FTWD, DSTs and operator reported kicks. These wells may be supplemented with fracture pressure data from FIT/LOT or LC
  • Class 'B' well - contains fracture pressure data from FIT/LOT or LC events and may be supplemented with mud pressures from operator reported mud weights.
  • Class 'C' well - contains mud pressures from operator reported mud weights.

The table below details our regional coverage for pressure wells within the database.

Who Uses Geopressure Data and How?

Georessure data is now widely used throughout the industry by Oil Companies and Service Companies alike. The data is used by several groups including exploration teams, drilling departments and developments teams to identify the subsurface pressure regimes and HPHT criteria.
