1. General Introduction and Overview

    This Cookbook was created so that ODP scientists can use this powerful but non-intuitive software with a minimum of training time. Step by step instructions are given to do the main tasks that are likely to be encountered in the lead up to, and during, an ODP leg. This not a reference guide to either IESX or even less to GeoFrame, but we have tried to cover what seemed necessary. The sections describing GeoFrame cover only the main features of GeoFrame, like the different application managers, the logic and the structure of the projects - which are all necessary to use IESX - but we do not cover the 'standard' geoframe procedures such as FMS processing.

    The only significant additions to version 1.0 of this document are:
        - a more complete description of check shots to define the time/depth conversion.
        - a description of some of the IESX utilities, and how to export the plots into convenient formats for other graphic applications.
        - a more complete description of the project manager and of the Data manager to allow users without a preliminary experience of GeoFrame to use IESX while taking advantage of some usefull GeoFrame resources.
        - We have also added a series of Frequently Asked Questions (FAQ) from our own experience troubleshooting and from the online GeoQuest product support (Appendix B) that address some of the problem that any one at sea might face without the recourse to the online support.
        - Finally, we have tried to highlightsome topics that cannot be overlooked without severe pain in the neck.

    IESX, a seismic interpretation software package, is part of Schlumberger GeoQuest's GeoFrame software. Geoframe has been used by the ODP downhole logging groups for several years to display and process ODP log data, particularly FMS images. The licenses for IESX were more recently acquired, and the software is being evaluated both at Lamont and on the Resolution (Leg 188, Leg 194, etc). This cookbook is one of the results of the evaluation period.

    The log and seismic data are organised into Geoframe `projects', usually one project for each ODP leg. The user must log in to the project to gain access to the data and the application modules that are used to load, process, and view the data. Inside the project, the `Data Manager' and the `Process Manager' are used to keep track of the data and the application modules, respectively. IESX is just one module within GeoFrame

    Examples based on ODP Leg 119 (Prydz Bay, Antarctica) occur throughout the cookbook. The 1982 BMR (Australian Bureau of Mineral Resources) seismic surveys of the area are now open-access, as is the downhole log data from the leg; together they constitute a good dataset for training.

    This version of the cookbook is based on GeoFrame 3.8.1, which is the current geoframe version at LDEO and most associated processing centers. There is no major difference when dealing with IESX with earlier versions of GeoFrame (3.8, 3.7 or 3.6).
