Loading and editing data
Load and edit an unlimited number of gauges,
rates, pressure and other data in almost any format
including ASCII, Excel™, PAS, DMP2, Merak and
databases via OLEDB & ODBC. Real-time links with
various acquisition systems, and data drag-drop
from other modules or from KAPPA Server.
Classical PA diagnostics
Multiple variants of the Arps plot.
Fetkovich type-curves
P-Q plots, to discriminate between transient and
boundary dominated flow
Normalized rate cumulative plot
A variation of the Agarwal-Gardner
Flowing material balance
Square root plot
Power law loss ratio plot
Well intake correction
When pressures are acquired at surface, or at any
point other than the sandface, they can be corrected
to datum using well intake models created by
Topaze, imported from third party software or from
Amethyste.
Modern PA diagnostics
The three main and complementary diagnostics
used in Topaze are the rate and pressure history
match, the loglog plot and the Blasingame plot. The
Blasingame plot displays, on a loglog scale, the
instantaneous and average productivity index, with
derivative versus material balance time. Type-curves
are also available. For gas material balance, the time
is replaced by the material balance pseudotime. The
simulated model can be compared to the data on
these three plots.
