DGI Announces CoViz Integrated Well Designer for CoViz 4D

Dynamic Graphics, Inc. Offers Preview of New Well Planning Tool, the CoViz Integrated Well Designer,at SPE Conference

During the Society of Petroleum Engineers Annual Conference, 30 October–2 November, 2011, Dynamic Graphics Will BePreviewing Its New Well Planning Tool for CoViz 4D.

DENVER, COLORADO—October, 2011

At the annual SPE conference, in Denver, CO, Dynamic Graphics, Inc. (DGI) will be offering a preview of a new well planningtool that will be available soon as an option to the popular CoViz 4D software. The new CoViz Integrated Well Designer allowsgeoscientists and engineers to plan well paths using CoViz 4D’s superior visualization environment. The CoViz Integrated WellDesigner can be used to create drillable wells within the context of the asset teams’ geologic, seismic, and other 3D and4D reservoir data.

Demonstrations of the CoViz Integrated Well Designer and other new features of CoViz 4D will be available at the DynamicGraphics booth (#2140) at the SPE ATCE in Denver, CO, 30 October –2 November, 2011.

“This tool signi�cantly improves the process of well planning by allowing users to design wellpaths within the completecontext of their data. This is in sharp contrast to the traditional method of simply handing off a series of exported locationsto a professional well planner who might not know the nuances of the reservoir. Our expectation is that this will increaseplanning ef�ciency and reduce costs in all phases of �eld maturity.” —Art Paradis, President, DGI.

About CoViz 4D

CoViz 4D leads the industry in providing dynamic quantitative analysis for reservoir management. Understanding the changingresponse of a reservoir over time is critical for optimizing production and development decisions. CoViz 4D makes it possiblefor users to simultaneously view and interrogate multi-disciplinary datasets from throughout the asset development team—regardless of the original data source. Understanding through data fusion—powerful in 3D—increases signi�cantly when usedin 4D: the unique temporal functionality in CoViz 4D allows users to visualize how development decisions affect their reservoir.For more information about CoViz 4D, visit www.dgi.com/coviz/cvmain.html.

The CoViz Integrated Well Designer offers well planning, ISCWSA standard tool models, anddisplay of geologic and drillers targets.
