Hampson-Russell’sH R ll’ project and database directory structures (this document is aimed to help support staff to understand the organization of Hampson Hampson-Russell Russell projects and well log databases) Using: CE8Rx releases Updated: Jan.2009 By: Tanya Colwell Table of Context ƒ Hampson-Russell’s concepts of well database and projects ƒ General well log database directory structure: well logs, culture, wavelets, display settings ƒ Project structure: internal well database, program-specific data, seismic volumes horizons volumes, horizons, data slices and faults ƒ Other issues with HRS projects - Adding more well data to an existing project - Locating input/output seismic - Packaging and moving projects - Multi-user Multi user environment ƒ Summary by typing a table. This database is usually referred to as an external database. Loading of the well logs into the Geoview database is always done as the first step. ƒ A project is created when you start a program such as AVO/ STRATA// eLOG// EMERGE// PRO4D// PROMC / ISMAP or SeisLoader. ƒ The well logs can be loaded into Geoview from ASCII. etc.Hampson-Russell Concepts: D Database b and d Project P j ƒ A database in Hampson-Russell software is a well log database created in Geoview. ƒ A project stores all the modelling and processing information (modified logs.) . horizons.
