Oil Pipeline Study: Field Data Validation and Detailed Fluid Characterization

Objective: Develop a thorough understanding of the reservoir fluid behavior and to model the fluid thermodynamic and transport properties accurately

Perhaps the most critical aspect of flow assurance design is to develop a thorough understanding of the reservoir fluid behavior and to model the fluid thermodynamic and transport properties accurately. This can often present a significant challenge as it requires reconciliation of field measured data with laboratory analysis work followed by the development of mathematical models that make use of this information to perform realistic predictions.

Working for an international oil company, RPS Knowledge Reservoir has recently completed a comprehensive review of field data collected from numerous gas condensate appraisal wells during drill stem tests (DST) and has developed pressure, volume, and temperature (PVT) models for the prediction of fluid properties as a function of local reservoir conditions. These models are being used to support the engineering of the subsurface and surface systems and to evaluate the economic feasibility of the field.

The results of the fluid characterization study were used to provide recommendations to improve future field sampling activities and laboratory testing procedures. An action plan was developed including recommended improvements to equipment, sampling strategies, and laboratory methods to mitigate any observed problems.
