Saphir Guided Session #7
A01 • Introduction
This guided session is an introduction to the functionalities of the Formation Test (FT) analysis
option in Saphir 4.12.
Warning: This Saphir feature is temporary, restricted to v4.12. We will remove it from later
Saphir versions, when an Ecrin module dedicated to formation testers is released. The
temporary Saphir addendum is aimed at unlocking our users who wish to have simultaneous
match of source and observation pressures. The future FT module will handle all FT surveys for
a given well in a single document. It will integrate a tool database, tool specific features, a
dedicated numerical model, gradients, contacts, etc. We cannot achieve a proper FT module in
v4.12, hence the temporary Saphir feature. Naturally, FT files created by Saphir v4.12 will be
read by following versions of Saphir and by the FT module.
In this exercise, the testing tool presents the following geometry:
Fig. A01.1 • Testing Tool Schematic
The tool has a single sink probe, and measures 4 pressure signals at the active probe (DSP1),
at an interference probe opposite to the active probe (DQP1), and at two distant interference
probes located 2.3 and 17 ft away from the active probe (BQP1, BQP2). Those pressure data
are completed by the direct measurement of the pumped volume during the test.
