Vacuum insulated tubing (VIT) is a specialized tubular designed to minimize heat loss from production or injection fluids to the environment in oil, gas and geothermal wells. VIT strings are used in deepwater wells for flow assurance or to mitigate a

The generation of a reservoir development plan with well locations, given a reservoir property map and a set of infrastructure constraints, represents a very challenging problem. The problem of selecting the optimal vertical well locations was formul

Differential-algebraic systems frequently arise in process engineering. However, optimization of these systems is rarely performed because this task is often difficult and time-consuming. In this paper we explore a simultaneous formulation for solvin

Many process optimization problems consist of large numbers of equations and only a few degrees of freedom. To exploit this feature an implementation of the range and null space decomposition (RND) strategy for large-scale problems is described, with

Vitamin abnormalities in eating disorder patients may contribute to altered neuropsychological status and the development of sequelae such as cognitive dysfunction. We examined the relationship between vitamin status and clinical indices in 13 low-we

Successive quadratic programming (SQP) has emerged as the algorithm of choice for solving moderately-sized nonlinear process optimization problems. However, as the nonlinear programming problem becomes large (over 100 variables, say) storage requirem
