A visualization for TIBCO Spotfire® to display well logs on tracks and fill in between the lines to aid visualization and interpretation of the data.

Well Log Mod for TIBCO Spotfire®

The well log visualization is a detailed two-dimensional record of tracks that can be used in petroleum exploration and production applications to show various physical, chemical, electrical, or other properties of the rock/fluid mixtures versus depth penetrated during drilling. Well-log visualization is important in E&P operations in the areas of analyzing electron density, resistivity, photoelectric effect, neutron absorption rate and other related properties, which in turn are useful in the determination of reservoir volume, hydrocarbon in place, reserves estimation and formation lithology

Background

The original Well Log Mod was developed by Justin Gosses called Wellio-viz.js available on his github repository

This is a complex mod that uses d3 and bundled with Webpack.

All source code for the mod example can be found in the src folder. Other necessary files reside in the static folder. Read below for further explanation.

Prerequisites

These instructions assume that you have Node.js (which includes npm) installed.

Data Requirements

This Mod works with pivoted data requiring at least 3 columns: Depth, Category and Value for the unpivoted categories. Here is an example of a small data set:

DEPTH	Category	Value
200	GR	113.9
200	CAL	176.867
200	PHIN	0.447
200	PHID	0.218
200	RESD	5.927
200.25	GR	112.033
200.25	CAL	175.83
200.25	PHIN	0.482
200.25	PHID	0.22

How to get started (with development server)

• Open a terminal at the location of this example.
• Run npm install. This will install necessary tools. Run this command only the first time you are building the mod and skip this step for any subsequent builds.
• Run npm start. This will bundle the JavaScript and place it in the dist folder. This task will watch for changes in the code and will continue running until it is stopped. Whenever you save a file, the changes will be reflected in the visualization mod.
• Run npm run server in a separate terminal. This will start a development server.
• Start editing, for example src/index.js.
• In Spotfire, follow the steps of creating a new mod and connecting to the development server.

Working without a development server

• Open a terminal at the location of this example.
• Run npm install. This will install necessary tools. Run this command only the first time you are building the mod and skip this step for any subsequent builds.
• Run npm run build. This will bundle the JavaScript and place it in the dist folder. It also copies the contents of static into dist. This task will not watch for changes in the code.
• In Spotfire, follow the steps of creating a new mod and then browse for, and point to, the manifest in the dist folder.
