| POSC Specifications Version 2.2 | CGM*PIP Volume 2 - PIP/III/1 and PIP/IV/1 |
Petrotechnical Open Software Corporation (POSC) is a not-for-profit membership corporation dedicated to defining an open computing environment for technical applications termed the software integration platform. Developed for the international oil and gas Exploration and Production (E&P) industry, the software integration platform is a set of specifications that addresses:
The goal of these specifications is to provide oil and gas organizations with methods to manage data resources and to support integrated multi-disciplinary projects. Using the POSC software integration platform contributes to this goal by improving the portability, scalability and interoperability of technical applications.
This book is Volume 2 of a two-volume set comprising the POSC Specification, CGM*PIP, Petroleum Industry Profile for CGM, which is one component of the software integration platform. The specification as a whole establishes the requirements to be met when two-dimensional graphical picture data that is vector or mixed vector and raster is used in the graphical interchange between petrotechnical applications employed in petroleum Exploration and Production (E&P) and related applications, using the format of the Computer Graphics Metafile (CGM).
Volume 1 of the
specification defines the core profiles of CGM:1992 elements, and defines
extensions for both Seismic Traces and Continuous Rendering. Two PIP profiles
are defined in Volume 1 -- designated
PIP/I and PIP/II.
Volume 2 defines extensions for drawing well logs. This volume defines two more PIP profiles -- designated PIP/III and PIP/IV.
POSC encourages the petroleum industry to use this book as a specification for acquiring and developing applications and implementations.
The contents of this document are based on three main inputs: the work of the Society of Exploration Geophysicists (SEG) Graphics Standards Subcommittee [1] 1, [2]; a POSC Request for Comments (RFC) on Graphics Metafile Format [3]; the CGM*PIP project document [4]. The SEG requirements document contains a number of recommendations for metafile capabilities. The philosophy of PIP/III and PIP/IV is to provide those features from the SEG Recommendations which received favorable responses from the RFC respondents.
The entire PIP document (both Volumes) is provided in electronic form. In all cases, the official reference for compliance with the specifications stated herein shall be the hard copy master maintained by POSC. Refer to the Compliance Note in the Preface of Volume 1 for additional information.
The development history of PIP/I and PIP/II is described in the Preface of Volume 1.
The PIP/III and PIP/IV efforts essentially started with the work of the SEG Graphics Standards Subcommittee, where it was realized that a metafile for the exchange of graphics within the E&P community could not be complete unless it included Well Log and Mapping/Contouring primitives. This requirement was carried into the initial PIP Project, but was not pursued due to time and funding limitations. The transfer of the PIP effort to POSC provided the necessary environment where the extensions could be developed. The need for such a set of extensions was verified by the E&P industry through their responses to the POSC RFC on Graphics Metafile Format issued in January 1994. The Basic Well Log extensions of PIP/III and the Advanced Well Log extensions of PIP/IV follow the recommendations received in the RFC responses and represent a portion of the work undertaken by the POSC Plot/Hardcopy Work Group.
POSC is the maintenance provider for the CGM*PIP specification. All defects, problem reports, questions, comments, and recommendations for future enhancements should be directed to the POSC Help Desk: help@posc.org.
This release completes POSC's current work on CGM extensions. Work on a new PIP specification, covering extensions for mapping and contouring, is anticipated. POSC urges users and developers to submit requirements in those subject areas and to participate in the development of the specifications.
This specification is intended for use by:
Under the management of David Archer, Chief Operating Officer, and Cary Purdy, Integration Environment Project Leader, the coordinator of this CGM*PIP, Petroleum Industry Profile for CGM document is Dortha Dougherty. The editor and primary contributor of the content of this document is Lee B. Metrick, Schlumberger/Austin Product Center.
POSC thanks all who responded to the RFC on Graphics Metafile Format and the community of CGM users who worked to develop the PIP specifications and to review the final draft. Special thanks go to the members of the POSC Plot/Hard Copy Work Group for the contribution of their expertise in developing the specifications and for their diligence in reviewing the preliminary and final drafts.
