A method for characterizing a subterranean formation traversed by a wellbore includes generating a reservoir model using data collected from the formation, generating a perturbation object comprising a perturbation of the wellbore, integrating the perturbation object with the reservoir model, and forming a geological model wherein the perturbation object is integrated in the reservoir model.

Integrating reservoir modeling with modeling a perturbation

A flow control apparatus for controlling fluid flow in a petroleum reservoir. The flow control apparatus has a flow control mechanism, a controller operable to control the flow control mechanism to adjust fluid flow through the flow control mechanism, the controller comprising a processor operable to execute according to a control algorithm, and a non-volatile memory connected to the controller. The non-volatile memory includes instructions to cause the controller to execute an authentication mechanism operable to authenticate a control computer and to prevent operation of the controller until the authentication mechanism authenticates the control computer.

LWD measurements to be used for proactive well placement while drilling a high angle or horizontal wellbore in a reservoir are defined. An initial reservoir model is provided and a section is extracted for a planned wellbore trajectory. A secondary model is generated for the planned trajectory. An area of interest is identified where statistical uncertainty is high. Possible causes of the statistical uncertainty are identified that are not present in the initial reservoir model. A set of parameters are defined based on the possible causes of statistical uncertainty. The area of interest is logged with LWD tool. Sensitivities of the LWD tool response to a subset of parameters are evaluated by performing tertiary model for a range of the subset of parameters. The most sensitive parameters from the subset of parameters and corresponding measurements are identified. LWD measurements are defined based on the most sensitive parameters.
