Sensitivity Analysis and Optimization of Surfactant-Polymer Flooding under Uncertainties.

Douarche, Frédéric; Veiga, Sébastirn Da; Feraille, … - HAL - 2014

Chemical flooding is currently one of the most promising solution to increase the recovery of mature reservoirs. In Surfactant-Polymer (SP) processes, several parameters should be taken into account to estimate the return on investments: concentrations of the injected chemical species, slug...

Mixed periodic-classical barrier strategies for Lévy risk processes

Pérez, José-Luis; Yamazaki, Kazutoshi - In: Risks 6 (2018) 2, pp. 1-39

Given a spectrally-negative Lévy process and independent Poisson observation times, we consider a periodic barrier strategy that pushes the process down to a certain level whenever the observed value is above it. We also consider the versions with additional classical reflection above and/or...
