The Gulf of Suez Petroleum Company (GUPCO) is a joint venture between BP
and the Egyptian General Petroleum Corporation (EGPC), focused on oil and gas
exploration and production in Egypt. Its portfolio includes eight operating
concessions in the Gulf of Suez, with daily production of over 78,000 barrels
of oil per day.
As part of its work on reservoirs such as Asal, Kareem, and Nubia in the
Gulf of Suez, GUPCO wanted to optimize its well perforation interval planning.
To achieve this, the company's existing workflows needed to be updated to
improve its pore-throat radius R35 predictions and capillary pressure
After meeting with Schlumberger experts it soon became clear
that a customized solution, based on the Techlog wellbore software platform and
using the Python application workflow interface (AWI), would overcome GUPCO's
Python workflow extension
Python open-source scripting capabilities are incorporated within the
Techlog platform to enable a variety of programming activities, from simple
calculations to complex interface and database implementations. The Python
editor within the Techlog platform allows access to all data objects,
mathematical and statistical routines, petrophysical calculations, and plot
The Schlumberger team worked with GUPCO to optimize key areas of its
wellbore analysis workflow using the Python editor. A new, more streamlined
process was created to calculate permeability and pore-throat radius R35. A
customized script was produced to compute all relevant input parameters in
seconds using the Gardner method, as well as the Young’s and Shear
moduli, and the capillary pressure and hydrocarbon column height against
different reservoir properties.
The Python editor provides a range of features, including the use of
scripts to access previously compiled code from languages such as C++ and
Fortran. A range of additional tools and library functions is also available
via the Python community.
