FracCADE* fracturing design and evaluation software is a field-validated fracturing simulator
developed on proven physical principles of hydraulic fracturing for an optimized treatment.
The system incorporates a range of complexities, from 2D models to extensive laterally
coupled three-dimensional simulators. The FracCADE software includes fully integrated real-
time monitoring, pressure matching, and redesign capabilities. The software also has data
handling, merging, and filtering capabilities, as well as customer reports and graphics.
The FracCADE software’s various modules add tremendous value:
optimization (npV) module
This module uses information about the well, the reservoir, the fluids, and the proppant in
conjunction with operational constraints, fixed costs, and production constraints to calculate
an economically optimum fracture design based on net present value. The goal of a fracturing
treatment is to maximize the economic return on a well, achieving the most cost-effective
treatment yielding the highest potential return on the client’s investment. The Optimization
(NPV) module plots enable engineers to study the economic effects of varied propped
fracture length ranges with selected fluids, proppants, and propped concentrations. Various
geometry models can be selected. Transient inflow performance relationship (IPR) curves are
used to forecast production.
The PropFRAC Placement module is a numerical hydraulic fracture simulator that uses a
different fracture geometry model. It provides the capability to model fracture growth into
layers above and below the pay zone along with fracture extension and rock mechanics that
allow screenouts and slurry dehydration to be stimulated. The stimulation can continue even
after proppant bridging or slurry dehydration occurs.
Scenario Manager is a new module in FracCADE that allows Schlumberger engineers to
create and manage multiple fracturing designs or scenarios at once. It allows on-site best
FracCADE software contains a variety of modules specially designed to improve production at your wellsite.
Tracking temperature and characterizing fracture geometry are among its functions, as shown above.
Fracturing design and evaluation software
matches against a real-time case and performs real-time visualization
of critical parameters, comparing them to presimulated calculations.
The AcidFRAC module enables you to create a comprehensive
simulation, taking into consideration the various mechanisms
involved in an acid fracturing treatment. The AcidFRAC module
simulates the effects of classical gel-pad-flush treatments, gelled
acid systems, LCA systems, and retarded systems. The Placement
simulator used in proppant fracturing is also used in acid fracturing.
AcidFRAC module calculations are based on a plugged flow along
the fracture. The cross-section etch area is based on averaged rock
properties along the fracture height.
The MultiFRAC Placement (MLF) module simulates simultaneous
initiation and extension of multiple hydraulic fractures. MLF supports
only PKN fracture geometry.
MLF models screenout due to proppant bridging or dehydration.
Cross-flow is calculated after pumping stops, but viscosity is ignored
so the value could be magnified. Perforation friction is calculated for

Added new parameters to Dynamic Digital Display Window.
The Bottomhole Pressure module converts:
Surface treatment conditions to bottomhole conditions by taking
a pumping schedule, containing pressures and rates at surface
conditions, and calculating the bottomhole values
Bottomhole conditions to surface treatment conditions by taking a
pumping schedule containing bottomhole data and calculating the
corresponding surface conditions
Added new parameters (cement wall thickness and thermal
conductivity) and implemented new heat transfer coefficient
Added an option of including viscous heating in bottomhole
This module analyzes the fracture data generated by the treatment,
which can be used to design a propped fracture treatment.
DataFRAC information helps to determine fracturing parameters
so future treatment design can maximize production. Fracturing
Fracture Closure Pressure
The Appropriate 2D Model
DataFRAC Fluid Efficiency
The DataFRAC module determines characteristics and parameters
specific to the particular well and formation that should be
considered when designing a propped fracture treatment. These
are graphically illustrated on interactive plots. Interactive plots are
used during the analysis to narrow the boundaries and arrive at a
The OPAL module provides easy integration with Optimized Pressure
Analysis (OPAL) so that results can be imported into FracCADE for
further analysis. OPAL is a pressure-analysis application for obtaining
reservoir closure pressure, fracture fluid efficiency, and fracture
height growth or confinement data based on real-time or treatment
Auto pressure Match
The Auto Pressure Match module presents a technique for consistent
analysis of pressure records during both injection and decline,
including changes due to rate and fluid viscosity variations. It is also
used to match simulated and measured fracturing procedures within
The procedure can be applied to both calibration test and propped
The module repeatedly executes the PropFRAC Placement module
using the prescribed treatment parameters (slurry injection rates,
proppant concentration, etc.) to predict fracturing pressures for a
given set of fracture parameters (stresses, fluid leakoff, etc.)
Additives and foams
The Additives and Foam Calculations module evaluates the rate of
at different conditions of pressure and temperature in
order to facilitate the design of a foam job. The Additives and Foam
Calculations Module performs volumetric calculation of liquid, solid,
, and N
at different temperatures and pressures.
The Additives & Foam Calculations module also provides the ability to
Design a CO

or at the discharge of the blender
Compenstate the quality due to the introduction of proppant.
The Log Analysis module provides you access to electronic log data,
either processed, full-wave sonic logs, or unprocessed Triple-Combo
logs through the standalone application LGZones.
It allows the import of zones from LGZones or the export of FracCADE
true vertical depth and width profile to LGZones. Once the electronic
log data is imported from LGZones, you can view them from the zones

Fracture length is determined based on the amount of injection
The fracture length needs to be specified; the injected fluid
required to attain the specified fracture length is then determined.
Because computations in the FGS module are analytical and can be
quickly executed, the FGS module is useful for sensitivity studies.
The Tubing Movement module is designed to calculate and provide a
profile of force effects on tubing and packers. The module simulates
the effect of four forces: applied, pressure-induced, frictional, and
thermally induced. Calculations take into consideration tubing to
packer motion, well completion type, current well conditions, and
changes which occur with treatment application.
The BRACKETFRAC module is used to control upper fracture
migration, lower fracture migration, or both simultaneously.
The BRACKETFRAC module is based on the need for placement
of diverting particles at the vertical limits of a fracture prior to
undesirable height growth.
The BRACKETFRAC module allows the option to design a treatment
using any of the following three fracture services:
INVERTAFRAC*— Prevents upward fracture propagation by
placing a layer of particles at the top of a vertical fracture.
DIVERTAFRAC— Contains downward fracturing by placing the
diverting material at the bottom of a fracture.
BRACKETFRAC— Combines the two treatments in the same
Added HiWAY module that enables the generation of HiWAY
The HiWAY module can be accessed from the PropFRAC
The link to the HiWAY module is visible only to the members of
HiWAY FracCADE LDAP group.
Users will be granted access to HiWAY module only after training.
Training will be provided as a part of the rollout.
HiWAY is based on a very novel approach to hydraulic fracturing.
The HiWAY service is a new, revolutionary type of hydraulic
fracturing treatment. HiWAY removes the dependence of the
fracture performance on the proppant characteristics. This is done
by creating open channels inside the fracture, which imposes
substantially higher hydraulic conductivity and a much more
conductive way for reservoir fluids compared to a conventional
fracturing treatment. In a HiWAY fracture, proppant is placed
heterogeneously in the form of proppant pillars surrounded by open
channels. The HiWAY module of FracCADE 6.2 generates the HiWAY
pumping schedule based on the conventional treatment. The HiWAY
module can be accessed from the PropFRAC Placement module.
Measuring stress contrast is one of the functions performed by FracCADE software.
Its modules also can be used to control fracture migration, as well as calculate and
provide a profile of force effects on tubing and packers.
