OpenSpirit^® Announces that Dynamic Graphics, Inc. Will Add OpenSpirit Data Integration to EarthVision^® and CoViz^® 3D Visualization Solutions SUGAR LAND, TEXAS – February 20, 2007 – Extending their proven track record of providing integrated, 3D software solutions for structurally complex petroleum reservoirs, Dynamic Graphics, Inc., creator of EarthVision^®, WellArchitect^®, and CoViz^® 3D software, has licensed the OpenSpirit application and data integration Developer's Kit to offer EarthVision and CoViz users increased integration with third-party applications and data stores. CoViz provides a vendor-neutral platform for 2D, 3D, and 4D covisualization, access, and interrogation of cross-discipline data. This collaborative environment enables asset teams to make better and faster decisions, with greater consensus and confidence. EarthVision is a 3D model building and visualization solution that allows end users to create and update precise 3D models for well positioning, reservoir characterization, and environmental analysis. EarthVision was lauded by the Petroleum Technology Transfer Council (PTTC) as a key contributor for improving the bottom line for independent oil and natural gas producers. “Our integration with common databases, such as OpenWorks^® and SeisWorks^®, and open formats, such as SEG-Y and RESCUE, already provides a critical time-savings mechanism for geoscientists and reservoir engineers,” says Art Paradis, President of Dynamic Graphics. “The ability of OpenSpirit to reach out to a multitude of other best-of-breed applications, data stores, and GIS systems will enable us to give G&G professionals even more control over their data.” “The idea of open and interoperable IT tools that help multidisciplinary teams leverage the best technology from different vendors is really gaining a foothold in the industry,” says Dan Piette, President and CEO of OpenSpirit. “Dynamic Graphics’ commitment to data accuracy, improved efficiency and reduced costs is a perfect complement to our own goal of providing an integrated solution that streamlines data management workflows and allows geoscientists to focus on their true mission – finding oil and gas.” About OpenSpirit The OpenSpirit Corporation, based in Sugar Land, Texas, began operations in July 2000 as an independent software company focused on providing integration solutions for upstream applications and data. The OpenSpirit application integration framework allows interoperability between multiple vendors' applications and data. To date, more than 40 software vendors have licensed the OpenSpirit developer's kit. Additionally, there are now more than 1500 oil company end users in more than 50 countries taking advantage of the framework to speed up critical workflows and enhance analysis in the geotechnical space, with more adopting the solution every day.
