A case study is presented involving Noble Energy Mississippi Canyon Deepwater (DW) Gulf of Mexico frac packs performed over the last 5 years. This presentation describes the role that proppant tracers and gravel pack (GP) logs played in improving operations, ensuring a complete annular pack, evaluating frac pack (FP) efficiency, and providing data for decision making as well as identification of best practices. Included in the presentation are eight (8) DW completions involving thirteen (13) FP treatments and an associated seventeen (17) GP logs that have been performed over the last 5 years in water depths ranging from 4,000 to 7,000 ft and reservoir intervals between 15,000 and 27,000 ft with pore pressures between 10.5 and 14.1 ppg.
The results and learnings described in this presentation can assist others in the industry when similar challenges are faced. Deepwater completions must be productive and reliable. Proppant tracing and gravel pack logging can assist the operator in real-time operational decision-making, production start-up procedures, and future completion design modifications, to ensure that maximum benefit is realized from the sand control treatment. It will be shown that this is another useful tool that every completion program should consider in order to ensure success and avoid preventable failures.
