Abstract: A technique for estimating the permeability profile of a well includes generating a well and formation model. The technique includes producing the well so that hydrocarbons flow from the formation and through the well. The technique includes measuring pressure at a plurality of points along at least a portion of the well without an intervention in the well and estimating a permeability profile along the portion of the well by use of the plurality of pressure measurements.

Abstract: A flexible interface and a method for employing the same are provided for interconnecting a client program with a workflow server running a workflow management system having workflow-type functionality. The interface includes a set of predefined protocol user interface pages including at least one control page. At least one first workflow platform-dependent object is provided for accessing the workflow functionality. At least one second workflow platform-independent object is provided for providing data to the first workflow platform-dependent object. At least one server program is provided that is callable by the control page to access the workflow functionality by invoking at least one of the first workflow platform-dependent object and the second workflow platform-independent object to promote data translation and exchange between the client program and the workflow management system.

Abstract: A method and apparatus for performing well planning and design includes performing a general-level design. The general-level design involves generating a proposed well configuration based on inputs from a user. The proposed configuration, generated by a software module, includes a well trajectory, the reservoir-wellbore interface, and completion equipment. The proposed configuration is refined by an optimizer based on a performance measure or a target constraint.
