Minifrac analysis
A workflow combines the G-function plot with
derivatives to define the leakoff behavior and the
closure pressure. It includes square root and after
closure analysis plots.
Slug and Pulse
Processing allows a modified version of the Ramey
function to match the slug pressure response of
a DST with Bourdet derivative type-curves. This
method can also solve for instantaneous production
with wellbore storage.
Formation tests
This option enables the interpretation of any number
of probes, active and interference, to discriminate
vertical permeability. Models for packer-probe and
probe-probe interference are included with the latter
considering storage and skin. An inbuilt preprocessor
handles LAS format files and calculates rates from
pump volumes.
This temporary (free) Saphir module will be re-written,
upgraded and removed in Generation 5 when a
dedicated module will be commercially available.
Reporting and exporting
Saphir has a range of comparison, reporting,
exporting and printing capabilities. The free and
unprotected Reader allows files to be read, printed
and exported without the requirement for an active
license. A slide presentation format is available to
use on an LCD projector or to create PowerPoint™
slides.
