Paradigm™ Rock & Fluid Canvas™ 2009 | Epos™ 4.0 Project Basics 1-1

Overview

Project is the Geolog application for managing projects and performing multiwell processing on large numbers of wells.

From Geolog Version 6.6 onwards, multiwell processing capabilities are also available in Geolog’s Well application. In Well, several wells may be loaded into memory, processed, and then the changes saved or discarded, as required. Therefore, it is strongly recommended that only a few wells be opened consecutively, based on available memory. If large numbers of wells are to be processed simultaneously, use the Project application (wells are not stored in memory, and data is immediately processed and saved to the database).

The following functionality is available within the Project application:

Project• Specify wells and sections to limit processing.

• Within the "processing wells" subset, specify wells to be displayed using the Datum

• Create well and section lists.

• Specify datum settings to process a specific range of data.

Catalogs• Display and modify details of wells via the Well Catalog.

• Manage sections via the Section Catalog.

• Perform batch administration functions on large numbers of wells.

See Catalogs for further information.

Mapsheet• Map and manage wells.

• Copy or include wells from other projects.

• Display maps of well locations using a variety of projections and basemaps.

• Display well deviation plots.

• Include CGMs as background map displays of contours, boundaries, etc.

• Graphically draw and display lines of section, and select wells that are displayed in cross section using Geolog’s Section application.

See Mapsheet for further information.

Xplot• Crossplot logs or log expressions from multiple wells.

• View and manipulate data in 3D format.

Project Basics 1-2Paradigm™ Rock & Fluid Canvas™ 2009 | Epos™ 4.0

• Perform regression analysis.

• Calculate new logs using contractor log interpretation charts, Ternary diagrams, etc.

See Xplot for further information.

Frequency• Create and format histograms of a single log from multiple wells to display the data distribution

and cumulative frequency curve.

See Frequency for further information.

Artist• Graphically create or update CGM files.

See Artist for further information.

Loglan• Create and edit Loglan modules for log processing and database access within the Project

application.

See Loglan for further information.

General Tools• The General menu lists a variety of tools for performing operations such as using mathematical

expressions to evaluate new logs or automatically remove spikes in a log. These operations, and many others in Geolog, start the Module Launcher to display a module for that operation. The modules, which are provided with Geolog, or created using Loglan, are used for displaying, creating, and editing data (for example, to show log values, edit output logs, etc.).

See General Tools for information on the individual tools found on the General menu, and “Using the Module Launcher” on page 2-31 for information on using the Module Launcher.

Petrophysics• Perform petrophysical analyses on all or a specified number of wells. Environmental

corrections, formation evaluation and defining pay-zone characteristics are examples of some of the functions available.

See Petrophysics for further information on all the available functionality.

Geology• Perform geological analyses, such as facies and/or permeability prediction from wireline logs,

facies propagation, dip analysis of array data, and image manipulation, on all or a specified number of wells.

See Facimage, Geomage and Fuzzy Logic for further information on functionality.

• Modules to import dips and tops data from the 3D geological model and modules to export data such as well paths and well tops in a .csv file format, and surface picks in an .xyz file format. These modules are detailed in "3D Model" on page 1-18.

See “3D Geological Model” on page 4-1 for further information about the creation and maintenance of the 3D geological module and “GS Wells” on page 4-1 for information on how it is utilized.

When the Project application is started; a blank Project window is opened with the Datum displayed, and all wells in the currently open project are available for display and selection in the Datum, Catalogs and/or on a mapsheet.

When you select Wells to Process from the menu you are selecting a set of wells from the project list of wells to be available in the Datum - Wells List which can then be selected for displaying and processing.

During a Project working session, all, or only a selected set of, wells and/or sections in a project may be specified for processing. Selecting wells/sections to process can be done using the:

• menu - see "Menu Selection" on page 1-6;

• “Datum” on page 2-5 - use the datum to limit the process wells displayed

• Catalogs - see “Wells to Process” on page 1-18 and “Sections to Process” on page 2-6, or

• Mapsheet - see “Graphical Selection” on page 1-7.

Menu Selection

To specify wells / sections to process

1. Select Project > Wells to Process... or click the icon, to display the “Multiple Select Dialog Box” on page 1-27 to select the wells to be available in the Datum - Wells List to be selected to process and/or display on a project view (e.g., mapsheet).

Well Lists

The Well List option is for saving selected wells as a group for quick retrieval for multiwell display and/or processing. You can create any number of well lists for any one project. Note that these well lists can then also be used in other Geolog applications to assist in quick retrieval (e.g. when searching for a well or wells to open in the Well application).

To create and save a well list1. Select Project > Well Lists... to display the Well List Maintenance dialog box.

2. Select the required wells (see “Multiple Select Dialog Box” on page 1-27 for information on using this dialog box).

NOTE ALL is a Geolog reserved well list name and is the default list which includes all wells in the currently open project, therefore, this name cannot be used for other lists.

3. Click on the Save As... button to display the Well List Save As dialog box.

4. Enter a name for the well list and click OK. The well list is saved to the project’s wells directory with the file extension .well_list.


To modify a well list1. Select Project > Well Lists... to display the Well List Maintenance dialog box.

2. In the SELECTION section, locate and select the well list in the Well List field. (To clear the Selection section, select the "blank" at the top of the list).

NOTE If you select a SOURCE well list first, and then select a SELECTION well list, wells are not displayed in the SELECTION section if they do not exist in the SOURCE well list.

3. To remove wells, click on the well(s) and click on the Deselect button.

4. To add wells, locate and select the well(s) from the SOURCE section and click on the Select button.

5. Click on the Save button to save the modified well list with the same name.

Or

Click on the Save As... button to create a new well list.

To delete a well list1. Select Project > Well Lists... to display the Well List Maintenance dialog box.

2. In the SELECTION section, locate and select the well list in the Well List field.

3. Click on the Delete... button.

4. Click OK to confirm the deletion.

Alternatively, Well Lists (and "Section Lists" on page 1-14) can be graphically selected and created from a mapsheet (see “Graphical Selection” on page 1-7 for further details) or created using the Catalogs.


Section Lists

A Section List is used to save a group of selected sections to specify sections to process (see "Limit / Specify for Processing" on page 1-6), or to display only that group of sections and their respective wells on a Mapsheet.

NOTE ALL is a Geolog reserved section list name and is the default list which includes all sections in the currently open project, therefore, this name cannot be used for other lists.

To create or modify a Section List1. Select Project > Section Lists... to display the Section List Maintenance dialog box.

2. Create, modify and delete Section Lists as described for "Well Lists" on page 1-12.


Setting Defaults

To reduce data entry, and improve performance, set and layout defaults can be specified. See “Setting Defaults” on page 2-3 in Using Geolog, and "Default Layout" on page 1-15 for further details.

NOTE Default settings specified are for the current working session only and need to be set each time Project is started.
