One exemplary embodiment presents a unified approach in the form of an Interactive "Visulation" (simultaneous visualization and simulation) Environment (IVE) designed to efficiently segment geologic features with high accuracy. The IVE unifies image structure analysis and implicit surface modeling as a surface-driven solution that assists analysts, such as geoscientists, in the segmentation and modeling of faults, channels, and other geobodies in 3-D data, such as 3-D seismic data.

Review of fundamental studies on lost circulation and wellbore strengthening

A visualization system for a wellbore environment includes a graphics processor for creating a computer rendered visual model of a well, and optionally a drill string, based on data sets of depth-varying and/or time-varying parameters of the well. The model is then displayed on a graphics display. A user interface facilitates user navigation along the length of the well to any selected region therein, and further permits user adjustment of orientation of the displayed renderings as well as a temporal selection of the time-varying data to be displayed. Simulated, real, or a combination of simulated and real wellbore data, which may be steady state, transient, or real-time data, may be visually depicted at any selected region. This provides the user with a visual indication of the wellbore environment as the user navigates the visualization spatially and temporally.

Three-dimensional wellbore analysis and visualization

A method for improving drilling performance of a drilling tool assembly is disclosed. The method includes identifying a drilling performance parameter to be improved. One or more potential solutions are defined to improve the drilling performance parameter. A drilling simulation is performed to determine the dynamic response of the drilling tool assembly during a drilling operation. Determining the dynamic response includes determining the interaction of a cutting element of a drill bit with an earth formation. Improvement in the drilling performance parameter is determined based upon the drilling simulation.

Methods for evaluating and improving drilling operations

A method for designing a drilling tool assembly, having a drill bit disposed at one end includes defining initial drilling tool assembly design parameters; calculating a dynamic response of the drilling tool assembly; adjusting a value of a drilling tool assembly design parameter; and repeating the calculating and the adjusting until a drilling tool assembly performance parameter is optimized.

Methods for modeling, designing, and optimizing the performance of drilling tool assemblies

A visualization system for a wellbore environment includes a graphics processor for creating a wire mesh model of a well and optionally a drillstring based on datasets of depth-varying parameters of the well. A graphics system maps appropriate textures to the wire mesh models, which are then displayed on a graphics display. A user interface facilitates user navigation along the length of the well to any selected location therein, and further permits user adjustment of orientation of the displayed renderings. Simulated, real or a combination of simulated and real wellbore data may be visually depicted in the wellbore at any selected location. This provides the user with a visual indication of the wellbore environment as the user navigates the visualization along the length of the wellbore.

Three-dimensional wellbore visualization system for drilling and completion data

A visualization system for wellbore and drillstring data includes a graphics processor for creating a wire mesh model of a well and drillstring based on datasets of depth-varying parameters of the well. A graphics system maps appropriate textures to the wire mesh models, which are then displayed on a graphics display. A user interface facilitates user navigation along the length of the well to any selected location therein, and further permits user adjustment of orientation of the displayed renderings. The data is sufficient to permit calculation of fluid velocity in the wellbore at any selected location. The fluid velocity is presented as a velocity profile in the rendered visualization of the wellbore and drillstring to provide the user with a visual indication of fluid velocity in the wellbore as the user navigates the visualization along the length of the wellbore and drillstring.
