Reservoir Continuity Assessment, Development and Management Services

Reservoir Continuity Assessment:

• Evaluation of the horizontal and vertical fluid connectivity among reservoir units is an essential tool for efficient management of petroleum assets. Intertek Westport utilizes hydrocarbon fingerprinting technology along with state-of-the-art chemometrics to provide the best possible reservoir continuity assessment.

Hydrocarbon Fingerprinting:

• The primary tool for fingerprinting hydrocarbons is high resolution gas chromatography (GC). Westport utilizes the best available high resolution GC. Westport analytical procedures are designed to assure maximum consistency among data including analysis of frequent standards and “same batch” analysis of samples from a single study. When required, Westport utilizes other analyses along with the high resolution GC.

Chemometric Assessment:

• Westport uses a variety of the most sophisticated chemometric techniques available to evaluate the data. Westport applies multiple techniques including principle component analysis, multivariate curve resolution, alternating least squares, and many others. Westport’s high resolution and consistency of the data, along with optimized data analysis, provide exceptional reservoir continuity assessment.

Reservoir Continuity Capabilities include:

• Optimization of data to minimize variations from sampling, storage and analysis.
• Objective assessment of continuity based on accurate measurement of sampling and analytical error.
• Recognition and correction for sample contamination that can permit inclusion of contaminated samples in continuity assessments.
• Identification and correction of variations unrelated to reservoir continuity such as light-end loss or wax precipitation.
• Recognition and characterization of variations within continuous reservoirs such as gravity segregation.
• Identification and removal of poor or irrelevant data that reduces precision.
• Determination of physical causes of variations (biodegradation, light-end loss, etc.)
• Measurement of reliability of the continuity assessments.
