Diamant Guided Session # 1
A01 • Introduction
Diamant is the Data Management module of Ecrin. The objective of this session is to illustrate the key features of
Diamant in its application to Permanent Gauge Data. You will be guided through the startup ofa project and the
loading of Permanent Gauge Data; the loading will illustrate the data filtration based on wavelets, and the data
dynamic updating.
This session is actually the first part of the Ecrin Guided Session #1. If you have a Saphir and a Topaze license,
you may extend the present session by joining the EcrGS01 at section D01 when you are finished. This will
illustrate the overallworkflow using the Ecrin integrated environment to transfer data, technical object, and
models between the data and analysis modules.

A01.1 • Requirements
The rate and pressure data used in this session consist of two files: EcrGS01q.txt, EcrGS01p.txt. The two ASCII
files are stored in a zipped file named “EcrGS01.zip” which can be downloaded from the KAPPA site, use the
menu WEB in the mainmenu bar of Ecrin and choose to connect to Ecrin download.
Note: After unzipping, the files will occupy 150 Mb on the hard disk. If Ecrin has been installed from a KAPPA
CD, the zip file will already have been copied to the Examples subdirectory.

B01 • Diamant overview
Before going through the tutorial itself, the following sections give a brief description of the main softwarecharacteristics and key features.
B01.1 • Diamant Master
Diamant Master is a “super” version of Diamant which aim is to centralize on a server the creation of the data
structure and the data filtration, and to make this information easily available to workstation users. Diamant
Master and Diamant are the same executable and the behavior depends only on the license. This means that to
run in Master mode,you need a specific privilege. Diamant Master has several functions not present in Diamant
Workstation, namely:
The ability to read data from data servers other than SQL, Oracle, or those with an ODBC interface. Access to PI
through its OLEDB interface is in particular restricted to the Diamant Master
The ability to create a mirror in BLIF format of any data source. This option is a must whendealing with large
amounts of data and a data server with slow access. BLIF stands for “Binary Large Index Files”. This is a
KAPPA internal format providing a fast data access in a compact form.
The ability to write back a channel to a database, in particular Oracle, and thus make it
When opening a Diamant Master file with a Diamant Reader, you can drag-and-drop any channel to your Saphir
orTopaze analysis.

B01.2 • Extensivedata access and data filtration
Diamant can load data from multiple data sources. From flat files, predefined databases, or production database
servers via tailored ODBC. In Master mode data can be read from PI servers using the PI OLEDB Provider.
Finally Production can be read for a group of wells from DMP2 files.
B01.3 • Wavelet filtering
Permanent gauge data can contain pressure,temperature and rate history over large production time periods;
accidental or planned shut-ins become ‘free’ transient tests that may be analyzed in Saphir. Whereas combined
pressures and rates allow for advanced production analysis in Topaze. The problem is that with current
downhole and surface acquisition the amount of raw data is vast. Simple filtering will exclude significant changes
