Introduction

The documentation describes how to to display wells and wells logs together with seismic in a 3D scene.

The presentation has a practical aspect from exploration drilling. After the initial phase with seismic 2D lines the next phase may be to drill wells to investigate further the interesting structures.

The involved features in Geocap are:

Info

title	Issues in Geocap when displaying well logs and seismic

Setting up a Geocap project that will contain all the data
Selecting command object menus into a dedicated set in shared commands
Reading SEGY files with 2D seismic lines into the project
Displaying 2D seismic lines
Reading well files with all the logs in LAS format into the project
Display the well string and all the logs in the 3D scene
Reading and displaying well tops information
Reading and displaying well log images
Applying a workflow to assist displaying the data

The documentation is a summary of the applied features in Geocap with references to other part of the documentation where the items are explained in more details.

A project in Geocap can be generated generic; i.e. along its development. It is however nice to have an initial setup. The project in this text is just called Wells and logs and referred to as the project. Here is the initial setup for the project with wells and seismic lines.

...

The contents inside the folders will gradually be generated along its use. The example shows what this test project may look like.

Working with the project manager and setting up a project is explained in project manager introduction.

Here is a quick explanation of the folders:

•Images. A folder to contain screenshots from the screen. Just a nice thing to have in order to save an informative display. The screenshots are taken by Images->Screenshots
•Seismic lines. A folder to contain 2D seismic lines that are present in the wells area. A seismic line is read by Seismic lines->Import->SEGY-2D
•Well log images. A folder to contain well log images from some paper reports that are saved as images in a picture format (jpeg, png, bmp, etc ) and read into the project. They can be calibrated and displayed in the 3D scene attached to its well.
A well log image is read by Well log images->Import->Generic. Browse in the images and use Automatic reading.

•Well tops. A folder to contain well tops. In this case the well tops are taken form NPD's facta pages .
•Wells. A folder to contain wells with all the logs. The wells are usually in LAS format and read into the folder with the LAS reader that is found under Wells->Import->LAS
