The IPTM database is simple to work with but also flexible. It can be just a single well for a quick look interpretation or a multi-well and multi-field database. An IP database consists of a binary data file (.DAT) for each well, each consisting of log curve data, general well information and interpretation ‘Parameter Sets’.
The Database Browser allows the user to interrogate an IP database in a graphical ‘Tree’ view.
Curve Sets are used to group curve data together in a flexible way that allows the user to manage the data as they wish, such as different logging runs, different types of data (e.g. irregular data such core data or pressure data), different interpreters or multiple output models. Each set can have a different top depth, bottom depth and data step.
High sample data from electrical and acoustic imaging tools are stored in array curves. This data can then be used for plotting and dip picking.
Text Curves are 'curves' containing text strings such as RFT pressure points, production test results, perforation depths or core descriptions, and can be created by ‘cut and paste’ from spreadsheets.
Picture Curves are graphics files, e.g. core photographs with a defined top and bottom depth allowing the picture to be scaled to the log data. IP recognises most common image formats.
Well Headers allow the user to enter and save well attributes and other important position, default petrophysical parameters and log acquisition data. There is also a comprehensive History Module that allows users to track changes made to curves and wells within IP.
IP has a full range of versatile Data Viewers including:
- log plot displays including horizontal log plots
- crossplots including 3D crossplots
- histograms including statistical summaries
- data listings
- 3D parameter viewer
- well map
- multi-well correlations
- montage builder
IP data loaders support the following data formats:
- LAS / LBS – batch loader for multiple files
The Interval Loader allows the user to load data such as a facies interpretation, where a certain facies is represented by a numerical value assigned over a particular depth interval. The Interval Loader can also be used to load periodic or discrete data, such as core plug analysis results or formation tester pressure data, or any discrete spreadsheet data.
The Capillary Pressure Data Loader is designed to assist the entering of PC data into IP and can load multiple plugs from different wells at the same time.
The Real Time Data Link module uses Schlumberger proprietary data link technology ('Osprey Connect') to enable an IP user to connect to a remote data server and download log curve and drilling data in real-time. The data can then be automatically analysed and displayed on all IP output graphics. This allows a real-time Petrophysical interpretation to be shown, which updates automatically as more data arrives.
IP provides connectivity to a number of External Data Repositories. These are for Paradigm's GEOLOG6®, Landmark Graphics Corporation's OpenWorks®, PETCOM's Powerlog® and Senergy's ODM3 databases.
Once a connection to an external database has been established, the following tasks can be performed:
- create new IP well from an external database well
- load selected curves into IP
- load well tops into IP
- edit and load well attributes
The Read / Write via OpenSpirit™ functionality allows the user to load and save data between IP and other OpenSpirit™-enabled databases such as OpenWorks™, GeoFrame™ and Recall™. The IP - OpenSpirit link requires the OpenSpirit™ system to have been installed on the user’s computer systems. More information about OpenSpirit™ can be found on their website www.openspirit.com
