Sand production and the sand control technique selected to mitigate
or eliminate it, can have a critical influence on the operation of oil
and gas wells. A completion that provides adequate sand control is
usually required, but an overly conservative design can have an
unnecessary, negative consequence on well productivity or injectivity.
The selection of the appropriate degree of sand control is not a
trivial process, as it depends on many factors including: the
characteristics of the reservoir formation, the in-situ stress state,
the reservoir pressure, the drawdown pressure, the near-well fluid
saturations, the well trajectory, and the capacity of the well for
handling sand in the tubulars and surface facilities.
Advanced Geotechnology has extensive experience in the prediction of
sand production risks for vertical, inclined and horizontal wells in a
wide variety of reservoir settings throughout the world. Our toolkit for
this type of analysis includes:
STABView™ - our leading edge sand production and
wellbore stability software with capabilities for a wide range of well
completions (slotted liners, screens, expandables, perforations, etc.);
Commercial numerical geomechanical models, such as FLAC,
for rigorous modeling of coupled fluid flow, rock deformation and rock
Empirical, experience-based criteria interpreted from
production data documented by various operators in settings around the
ROCKSBank™ – our commercial database of
petrophysical and rock mechanical properties for reservoirs and caprocks
from around the world.
Our staff are highly skilled in the process of extracting maximum
value from available datasets such as wireline and LWD log and core
data, identifying and guiding future data collection needs, and
providing recommendations for appropriate well completions. Our
integrated approach draws on our experience in geology, petrophysics,
rock and soil mechanics, multiphase flow modeling, wellbore hydraulics
and production engineering.
