3 GeoCenter LP provides the latest in seismic data processing services and technology to the oil and gas industry. Founded in 1980, GeoCenter has steadily built a processing services staff of highly skilled geophysicists with diverse industry experience including seismic data acquisition, data processing, exploration and production and software engineering. Our geophysicists have over 200 years of combined experience, working on projects involving data from most of the significant geological provinces of the world. We have developed real world experience from successfully imaging challenging depositional and structural environments. GeoCenter strives to provide exceptional processing services to the major oil and gas companies, large independents, and smaller start up companies, with total client satisfaction as our mission. Although GeoCenter began as a data processing company, its founders quickly saw the need in the oil and gas industry for more approachable, graphical seismic processing technology. We focused on putting together a research and development team comprised of geophysicists, mathematicians, and software developers to meet the challenge. By 1990, we were well on our way to developing an interactive seismic data processing software program that would prove to be revolutionary in its flexibility and productivity. In 1992, GeoCenter was proud to introduce the SeisUP Production Seismic Software Processing System to the industry. Today with a research staff with over 130 years of combined experience and over 200 SeisUP licenses installed world-wide, we continue to broaden the scope and functionality of SeisUP every year. The GeoCenter processing staff and SeisUP developers occupy the same facility, and because of this close interaction, real processing and client needs drive software development to ensure that software tools keep pace with the ever evolving technological environment. With the dedication to utilize the best new technology, applied by a staff with great depth of experience, GeoCenter continues to be a leading provider of quality, performance-driven services and technology to the geophysical industry.

4 S e i s m i c P r o c e s s i n g S E R V I C E At GeoCenter, clients are the foundation for our business. We firmly believe the client must be involved in every phase of the processing flow. Our client s knowledge of the geology and processing objectives will help produce a superior data set. Information such At GeoCenter, we believe the definition of value combines a high level of service, flexible technology, and turnaround as near surface geology, well logs, and acquisition environmental conditions provided by the client helps with geometry validation and refraction static interpretation. Understanding these processes gives the client an understanding of localized signal to noise and resolution issues. commitments. Our focus is to create a competitive advantage for our customers and their exploration and production efforts. To aid in facilitating client interaction, we maintain remote access to our processing system. This software allows the client and processor to interact with the same processing session and work together seamlessly on a project. We also maintain a FTP site for the interchange of data sets such as stacks and gather subsets. Clients routinely download data through this vehicle for quality check purposes or for delivery of final products. Data delivery is also made available via traditional media. P A G E S 2 3

7 C E N T E R C A PAC I T Y GeoCenter utilizes a state-of-the-art data center to meet our processing and development needs. The data center is at the core of our facility featuring a scalable architecture. The design can meet changing needs and expand with the company by exploiting the integrating power, cooling, rack, and management infrastructure. This approach provides increased availability, improved adaptability, speed of deployment, and produces high availability through redundancy. The design also reduces risk of failure, human error, and lowers mean-time-to-repair. Finally, the center structure and design creates a high level of security and reliability for all processing and development projects. GeoCenter s data center features a fully scalable architecture that improves our adaptability, increased availability, speed of deployment, and produces high availability through redundancy.

8 T e c h n o l o g y GeoCenter began as a seismic data processing center, but it soon became evident that custom processing software would have major benefits not only to the company but also to our clients. In this spirit, SeisUP was created. The processing staff and SeisUP developers interact seamlessly together, and because of this close interaction, real world processing and client needs drive software development and ensure that software tools keep pace with processing requirements. The close relationship between processors and SeisUP developers is a major benefit to both service and technology providing flexibility to SeisUP was developed as a 3D interactive processing environment. Processing flows are built through an interactive graphical user interface. Data is QC d interactively even as a job is executing. Rapid interaction increases data throughput. A processor can quickly investigate problems relating to any aspect of a data set. our processing system. The relationship between processors and SeisUP developers is a major benefit in both service and technology. Adjustments and enhancements to the software can be implemented quickly. The processor and clients have ready access to the latest tools and algorithms developed for SeisUP. SeisUP flexibility: If a module does not exist for a defined process, it can be constructed from other existing modules. An example is the implementation of a procedure to compute converted wave refraction statics using interactive stacking of refraction arrivals. P A G E S 6 7

11 U S E R I N T E R FAC E SeisUP utilizes a graphical interface featuring a workspace containing a set of user specified flows. Data sets and processing modules are linked together with pipes on the canvas. Modules can be inserted from a module library or copied from existing flows and parameters are defined through pull down menus accessed through the module icons. Spreadsheet type parameters, such as velocity functions and mutes, are stored in a database and are available to any module within a project. Job execution is controlled via a job server that accepts job submission from any SeisUP platform on the network. Utility applications such as the Job Monitor, Data Manager and History Viewer show active job status, data set and storage management and information about previous job executions. I N P U T/O U T P U T SeisUP can import all standard seismic field data formats and most variations. Standard field header data, such as geometry, are routinely extracted and stored in processing trace headers and the database as needed. Additional header words may be extracted and mapped to processing trace headers. SEGY format may be imported and exported with complete header word mapping flexibility.

12 D A T A P R E P A R A T I O N Data preparation includes geometry assignment and validation as well as trace editing and polarity correction, all accomplished via interactive displays. Geometry information may be captured from trace headers or entered through a spreadsheet style interface. Coordinate data is easily entered through a Matrix Editor or imported from ASCII files such as SEGP1 and SPS format files. There is an extensive library of tools to manipulate trace header attributes when necessary. D E V E L O P E R T O O L K I T Because of the modular structure of SeisUP, functionality is easily added by the experienced programmer as a que module. API s and documentation are provided for modules written in FORTRAN 77, C, or C. Trace data are passed to a module in a buffer, one ensemble at a time along with pertinent data describing the traces. S e i s U P F I E L D P R O F E S S I O N A L SeisUP Field Professional is built upon the same SeisUP core, but with fewer modules included, allowing field acquisition crews to process seismic data through the brute stack stage. This added capability will offer superior quality assurance as well as increased productivity from your acquisition crew. P A G E S 10 11
