A method for producing hydrocarbon fluid, such as crude oil and/or natural gas, through a well or well cluster of which the trajectory is at least partly defined and iteratively optimized by an well trajectory optimization algorithm that is coupled to a finite difference reservoir simulation program that represents a hydrocarbon fluid containing reservoir as a set of grid cells with a specified permeability and fluid content, wherein the algorithm:

Method for producing hydrocarbons through a well or well cluster of which the trajectory is optimized by a trajectory optimisation algorithm

A method of heating a subsurface hydrocarbon containing formation includes providing heat flux per volume to a first portion of a subsurface hydrocarbon containing formation. The heat flux per volume is provided by two or more first heat sources positioned in the first portion. Heat flux per volume is provided to a second portion of the subsurface hydrocarbon containing formation with the heat flux per volume being provided by two or more second heat sources positioned in the second portion. The heat flux per volume provided by the two or more second heat sources is greater than the heat flux per volume provided by the two or more first heat sources. The second portion is positioned below the first portion.

Irregular pattern treatment of a subsurface formation

A method is disclosed for controlling production of oil and/or gas from an underground reservoir by means of a closed loop production control system, in which: an assembly of monitoring sensors () monitor the physical properties of hydrocarbon and other fluids within the reservoir; a plurality of high order and/or low order mathematical reservoir models () calculate each an estimate of the physical properties of hydrocarbon and other fluids in the hydrocarbon containing formation and in the wells; the mathematical reservoir models () are iteratively updated in response to data provided by the assembly of sensors such that any difference between the properties monitored by the assembly of sensors and those calculated by each of the reservoir models is minimized; an optimal mathematical reservoir model () or an optimal combination thereof is selected during at least one updating step for which an averaged difference between the calculated properties and the properties monitored by the assembly of sensors () is minimal; and an optimization algorithm () controls, on the basis of data provided by the selected optimal mathematical reservoir model or optimal combination thereof, production control assemblies of a plurality of wells which traverse the formation.
