In an effort to evaluate the impact of incorporating convenience food products into Navy menus, the U.S. Army Natick Research, Development and Engineering Center with the assistance of Information Technology Solutions, Inc., developed the Convenience Food Logistics Model (CFLM) for the Naval Supply Systems Command. This management tool generates an optimized menu by substituting a user selected percentage of Armed Forces Recipe Service (AFRS) items with convenience food products. The optimization tool is a stand‐alone Windows application which allows for optimization based on food cost, labor hours, and dry, chilled and freezer storage requirements. The results obtained and their implications for developing strategies to minimize logistical requirements for existing ships and 21st Century Navy warships are presented in this technical paper.
Horizontal wells experience transient flow regimes throughout their long laterals. The average gas/liquid ratio (GLR) produced by a horizontal well may not overwhelm an ESP if the fluids travel in a steady stream. However, gas slugs commonly develop in the lateral section of a horizontal well, growing in size as they approach the heel of the well and move into the vertical section of the wellbore. A well with a pump intake pressure (PIP) of 500 psi at the ESP gauge may have plenty of fluid over the pump intake and still have problems with gas locking the pumps. Even with sophisticated gas handling pumps and gas lock-breaking control algorithms in the variable speed drive (VSD), the ESP still goes down with a gas locked pump.
This paper covers a patent pending technology developed at EOG Resources' Production Technology Center that improves gas-liquid separation of fluids entering an ESP. The tool has been installed in wells with high GLRs, where ESP run times are lower than the field average, and has improved operational stability. This paper follows the development of the technology in the model wellbore at EOG's lab, the design and manufacturing of field trial separators, and the results of several field trials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
