IHS ENERGY Gulf of Mexico Formation Pressure Database With the expanding frontier of deepwater exploration and increasing interest in Tertiary reservoirs on the shelf, it has never been more necessary to understand the formation pressures encountered while drilling a well. Understanding these pressures is an essential component of upstream hydrocarbon activity, from exploration through operations to appraisal and development. From an exploration stand point, having access to this data can assist in the understanding of hydrocarbon migration and entrapment, hydrocarbon column integrity and hydrodynamics. In the operational environment, pressure is invaluable for well planning, impacting on casing designs, mud programs and health and safety.

Gulf of Mexico Formation Pressure Database
With the expanding frontier of deepwater exploration and increasing interest in Tertiary reservoirs on the shelf, it has never been more necessary to understand the formation pressures encountered while drilling a well. Understanding these pressures is an essential component of upstream hydrocarbon activity, from exploration through operations to appraisal and development.
From an exploration stand point, having access to this data can assist in the understanding of hydrocarbon migration and entrapment, hydrocarbon column integrity and hydrodynamics. In the operational environment, pressure is invaluable for well planning, impacting on casing designs, mud programs and health and safety. In appraisal and development, pressure analysis can assist in determining reservoir connectivity, fluid contacts and lateral or vertical seals.
Having access to this data enables explorationists and engineers to make valid geological and engineering interpretations. With the data being reinterpreted, standardised, and quality controlled by in-house pressure experts, any apparent trends are the result of subsurface conditions, speeding up the decision-making capabilities and providing a competitive edge.
The database contains pore pressure data measured directly from Wireline Formation Testing (e.g. RFT™, MDT ™) / Formation Testing While Drilling (e.g. GeoTap ™) and reported kick incidents, fracture pressures from Formation Integrity / Leak-Off Tests and reported lost circulation events, in addition to mud pressures calculated from drilling mud weights and temperature data from logging runs.
Standardized, reliable and easy to access digital reference of formation pressures from publicly released offset wells
BENEFITS:
Exploration and operational personas use the Gulf of Mexico Formation Pressure Database to make valid geological and engineering interpretations.
Current uses of the Gulf of Mexico Formation Pressure Database include:
•Mappingregionalporepressuredistribution
•Reservoirfluidcontactsandconnectivity
•Fractureanalysis
•Wellprogramdesign
•IntegrationofproprietarypressuredatawiththeIHSoffsetwelldata
•Calibrationofporepressuremodelsfromseismicvelocities,mudweightsandbasinmodellingwithactualpressuremeasurements
7166-1114TB
Data SourcingThe data is sourced from public and proprietary well records, i.e. Physical Formation Evaluation Logs/Mud Logs, Wireline Formation Test Logs and Logging While Drilling Logs. The IHS data processing and quality control entails interpretation and validation of test pressures, corrections for pressure units and hole temperatures and standardisation of gauge depths to the vertical
Benefits• Standardised, reliable and easy to access digital
reference of pressure
• Savings in time and money. The preparation of proprietary databases involves considerable in-house resources and budgets. The IHS database saves customers the effort of sourcing, processing, interpreting and storing the data
• Convenience. The database has a user friendly Microsoft Access™ front end for well selection and offers functionality for exporting the data to Microsoft Excel™
• The database can be used to help develop a safe drilling program which could save millions of dollars and potentially save lives
• The database will save 28 man-years of data sourcing, processing and reinterpretation, equating to an investment of $2.1 million assuming a flat rate of $75K/year
Deliverables• Digital copy of formation pressure database in Microsoft
Access™, Excel™ or ASCII format, as determined by the customer
• The database includes, well header data, casing and liner data, fracture pressure data, temperature (BHT) data, formation pressure data, gas event data, formation tops, drilling comments, formation water salinities and drilling mud data
Deepwater Wilcox Pressure StudyIn partnership with Ikon Science Americas, IHS released a Deepwater Wilcox Study in 2010.
Data content per well may vary dependent upon data availability.
