Abstract Although gas-lift is an established technology for improving the performances of oil production wells, simplicity, robustness and accuracy models remain to be fully resolved. As improvement on traditional practice, this paper proposes a new approach modelling performance gas-lifted wells at steady-state conditions. The conceptual framework splits wellbore into two segments. segments ar...
The lift-gas allocation problem with pressure-drop constraints and well-separator routing is a mixed-integer nonlinear program considerably hard to solve. To this end, a mixed-integer linear programming formulation was developed by multidimensional piecewiselinearization of pressure drop functions using standard (CC) and logarithmic (Log) aggregated models. These models were compared by means o...
A method to pattern infrared-absorbing gold black by conventional photolithography and lift-off is described. A photo-resist pattern is developed on a substrate by standard photolithography. Gold black is deposited over the whole by thermal evaporation in an inert gas at 1 Torr. SiO2 is then deposited as a protection layer by electron beam evaporation. Lift-off proceeds by dissolving the photor...
Background: There is considerable professional debate over which technique is the best for lifting. The aim of this study is to compare three static lifting styles, the stoop, semi-squat and arm lift, using maximum isometric voluntary contraction (MIVC) as one indicator for recommending a lifting style. Methods: Thirty healthy women (mean age: 22.37 years) participated in this quasi-experiment...
The numerical simulation of the dynamic interaction between hydrocarbon reservoirs and wells has been an object of study for over three decades. Such a coupled approach is necessary to solve a variety of dynamic flow problems, such as pressure transient analysis (well testing) with wellbore storage, liquid loading, near-well reservoir clean-up, unstable gas lift, or the development of smart wel...
