In an oil field that has reached its maximum gas handling capacity, and where wells are producing under gas coning conditions such that the gas-oil ratio (GOR) depends on the wells production rate, oil production is maximized if the marginal GOR (mGOR) is equal for all wells. The GOR and the mGOR are not readily available measurements, but they can be predicted using detailed reservoir models. ...

This paper presents a method for optimizing oil production on large scale production networks such as the Troll west field in the North Sea. The method is based on piecewise linearization of all nonlinearities, and on decomposition of the full scale problem into smaller sub-problems. Column generation in a Branch & Price framework is used to solve the decomposed problem. The methods differs fro...

Fat embolism to the systemic circulation in polytrauma patients is very common. The fat embolism syndrome (FES), however, is a rare condition. We describe a case of traumatic femur fracture with FES that was presented as acute tonsillar herniation (coning) and brain death postoperatively. We believe that in this case the prone position and moderate hypercapnia contributed to the acute coning.

Implicit pressure-explicit saturation method (IMPES) is widely used in oil reservoir simulation to study the multiphase flow in porous media. This method has no complexity compared to the fully implicit method, although both of them are based on the finite difference technique. Water coning is one the most important phenomenon that affects the oil production from oil reservoirs having a water d...

in this paper, the effect of hydrocarbon fluid properties on water coning in fractured reservoirs, using a black oil numerical simulator has been studied. effect of each parameter has been investigated both separately and also with the construction of different models. using separate constructed models.primarily the hydrocarbon fluid density, viscosity and also water density as effective parame...
