Head & base production optimization : inventory management strategy
A new inventory management strategy was developed for Schlumberger to reduce waste in material handling and improve the warehouse receiving efficiency. The current warehouse receiving situation was analyzed; then the receiving procedure was summarized and the time spent for each step was measured. …

Hybrid Make-to-Stock, Make-to-Order (MTS-MTO) production optimization and predictive manufacturing plan
… a hybrid make-to-stock, make-to-order (MTS-MTO) production optimization model will lead to pre-building between 1.1M and 2.1M retail units per year, but could be scaled upward. Pre-building allows for cost savings through economies of scale in manufacturing and through transportation savings …

Program transformation and code generation for developing, modeling, and optimizing GPU programs
… To help bridge the gap between fully automated optimization, which does not reliably produce optimal code, and fully manual optimization, which is inefficient and error-prone, we present three mechanisms facilitating a human-guided, partially automated process for production, optimization, and …

A Parametric Study and Economic Evaluation of Drilling Patterns in Deep, Thick CBM Reservoirs
Over the past decade, the production from unconventional reservoirs such as coalbed methane has increased dramatically. The focal driving force for this growth in coalbed methane production was the development and promulgation of reservoir engineering and completion technology.;There have been many …

Optimizing oil production in horizontal wells (water/oil cresting in horizontal wells)
… Cresting poses problems such as uneconomic oil production rates due to increasing volumes of effluent(s) (unwanted water and or gas) produced with oil over time as well as the overall recovery efficiency of oil reservoirs. Production optimization from crest-affected thick- and thin-oil rim …
