Improving Predictions of Hydrocarbon Resource Volumes -
Density and Viscosity Experimentation and Modeling at Extreme Conditions

HPHT Environment in Ultra-Deepwater Reservoirs
(up to 35,000 psi and 500°F).

Increasing offshore domestic oil and natural gas activities associated with ultra-deepwater reservoirs such as in the Gulf of Mexico poses unique technical and operational challenges. One of the challenges is to develop critical data for predicting in situ conditions that are required for assessing recoverable oil, drilling design, and control of blowouts in offshore hydrocarbon settings.

The objective of this project is to develop methodologies and technologies to reduce subsurface uncertainty and improve deep drilling safety and oil production under high pressure/high temperature (HPHT) conditions by increasing the accuracy of equation-of-state (EOS) models and viscosity correlations. The ability to reliably predict the thermophysical properties of hydrocarbons over wide ranges of temperatures and pressures, will provide a means for accurate predictions of the recoverable reserves and will promote safe and secure production from these critically important reservoirs.

The goals of this project are to continue expanding and disseminating the database for crude oil viscosity/density at extreme temperature and pressure conditions associated with deep drilling and to further develop and refine predictive crude oil density and viscosity models. These data, models, and tools improve the quality of the predictions of hydrocarbon properties at extreme operating conditions.
