Fluid Profiling for Reservoir Evaluation: Norwegian Case Studies

Recent advances in sensor technology and petroleum science allow using downhole-fluid-analysis (DFA) data to improve confidence in reservoir architecture. New independent work flows are especially valuable when used in concert with pressure/volume/temperature (PVT) reports, well-test data, static-pressure gradients and other common techniques used to assess reservoir architecture. This paper presents two real-field case studies from the Norwegian continental shelf that use available DFA data to support the assumptions made from other data on reservoir architecture between wells.

Introduction

A valuable plan to manage subsurface uncertainty assesses the effect of fluid properties on the project execution. Understanding the fluid properties and their vertical and lateral distribution will elucidate quality and continuity of the discovery during the exploration-and-appraisal phase and extend into deciding on development options. The fluid distribution in the reservoir is a function of source-rock material, migration path, charge history, charge mechanisms, processes working toward fluid equilibration and disequilibrium, geologic setting, burial history, reservoir architecture, and timing. Therefore, an interdisciplinary approach is necessary to make use of the information contained in the fluid distribution to constrain the understanding of processes that affect production. The level of confidence rises with the data quality and data availability. Acquiring high-quality data to map spatial variations of fluid properties across the field is an integral part of this methodology.
