KAPPA Server (Ks)
Permanent downhole gauges (PDG) constantly
monitor downhole pressures. They provide long-
term data to run production analysis (PA) and short-
term data, from incidental shut-ins, to perform single
or multiple pressure transient analyses (PTA).
KAPPA Server is a client-server solution that
loads, processes and shares standardized data
within a workgroup and establishes real-time links
with Intelligent Fields and third party databases.
OpenServer APIs allow third party applications to
retrieve data and analyses.
Pressures and temperatures are processed using
wavelets. Rates, previously requiring extensive
manual intervention to correct inaccurate reallocation
processes, are solved with an algorithm that identifies
shut-ins with high reliability.
Using gradient discrimination, KAPPA Server then
automatically identifies shut-ins scanning years
of PDG data in seconds. These identified shut-ins
are then made available to the user for analysis in
the PTA module (Saphir). The combination of these
processes leads to perfectly synchronized pressure
and rates allowing immediate single or bulk analysis.
Sharing data and technical objects
KAPPA Server and the Ecrin modules share data and
analyses back and forth. This data is then available
to workgroup users.
This also applies to technical objects such as PVT,
reservoir maps, relative permeability tables, intake
curves, IPR’s, analytical and numerical models.
PVT objects may be tables, black oil correlations or
an EOS. In Saphir, Topaze and Rubis this may be
isothermal. In other modules Emeraude, Amethyste
and Rubis, temperature dependency may be
required. When dragged and dropped from one
environment to another a PVT object will adapt from
isothermal to non-isothermal, or vice versa.
Analytical models may be exchanged between
Saphir and Topaze. It is possible to convert a whole
document, with information, data and models, from
PTA to PA or vice versa.
