SimWorx Team
• Graduated students from LabMeC
• Different experiences with research applied to numerical methods. – Edimar Cesar Rylo: Dr. Eng.
– Gustavo Camargo Longhin: M.Sc. Eng.
– Tiago Luís Duarte Forti: M.Sc. Eng.
What we do
• Development of numerical simulators – Writing C++/VB/Delphi
• Engineering projects automation tools.– Stand alone applications– Autodesk (ARX, VBA, LISP)
• Numerical simulations using comercial applications. (Ansys, Nastran, etc);
• Courses for subjects such as:– Comercial simulators– Symbolic programming applications
Oil Industry Applications
• Developed with a Petrobras and Labmec partnership. Well Engineering Department.
• Applications for:– Hydraulic fracturing.
• Water Injection with Fracture Propagation.• MiniFrac log analysis.
– Selective perforation.• Determination of an ideal hole distribution.
– Productivity Index determination in open-hole wells.
The SimWorx / LabMeC Implementation Models
• Developed according to Object Oriented Philosophy– Easy mantainance and extension.– It better addresses complexities.– Allows for code reusability.
• Developed in C++– Increases kernel performance.
• Extensive use of Components.– Proprietary.– Developed in house.
Hydraulic Fracturing Applications
• The SP3D application– Started development back in 2002.– A CENPES and LabMeC combined effort.– Served as the base project for the LabMeC CENPES long
relationship.• The Propag application
– Still evolving and incorporating new models / technologies.– A mantainance contract exists to support the necessary
evolution.
The Propag Application
• Numerical Simulator for:– Water injection with fracture propagation.
• Its numerical model contemplates:– Formation’s Mechanical Behavior.– The flow of water through the porous medium.– The flow of water through the fracture opening.
• Developed in C++.• Based on Object Oriented Techiniques.
The Propag Application
• Runs on regular PCs.• Requires regular computational resources.• Runs on Windows environment.• Has an intuitive user interface with:
– Reports.– Charts.
• Developed as MDI (Multi-Document Interface).– Inproves data analysis.– Software Industry consolidated feature.
The Propag Formulation
• The numerical kernel of Propag.– Incorporates lots of different models.– Evolves based on Petrobras requirements.– Evolves according to availability of new technologies.
Propag (GUI Overview)
Generic simulation data
Injection fluid data
Oil specific data
Finite Elements simulation specific data
Reservoir data
Horizontal or Vertical Well simulations
Confinement stresses
Actuating stresses
• Can be entered by the user.• Or estimated by the application based on input data.
Injection planner
• A spreadsheet like interface allows for the injection planning inputs.– User select units for
• Injection time.• Flow rate.
– In the example• 3000 days injecting 4000 m3/day• 50 days without injection• 1000 days injecting 6000 m3/day• ...
Horizontal or Vertical Well
• Input specific for Vertical Well– Diameter of Holes (Perforation)– Number of Holes
• Input specific for Horizontal Well– Diameter– Length
Preliminary values
• Fracture initiation pressures– Non penetrating fluid.– Penetrating fluid.
• Fracture initiation (surface data)– Flow rate.– Pressure.
• Filtration coeficients.– Cv (CII)
• Reservoir compressibility and viscosity coefficient.
– Cw (CIII)• Filter cake coefficient.
– CL • Total leakoff coefficient.
Reports• Spreadsheet table
with a timestep wise finite element solution.
Charts
• Plots for– Front position– Propagation pressure– Surface pressure– Fracture openning– Fracture height– Fracture volume– Efficiency
Front Position
Propagation pressure.
Fracture openning
Data exchange features
• Exports charts.– Bitmaps (figures)– MS Excel spreadsheets– ASCII text.
Chart customization
• Fully customizable chart component allowing for:– 3D charts when necessary.– Exporting.– Editing.– Etc.
Contextual Help enabled
• Hitting “F1” triggers the specific help.
Future work

ProDiv Application
• Application for Design and Analysis of Inflow Control by Unevenly Distributed Perforation. – Contemplates
• Producion• Injection• Acidization
ProDiv background
• Complyes with the LabMeC / SimWorx development model.
• Based on the same computational frameworks of ProPag.
• Developed according to Object Oriented Philosophy.• Written in C++.
ProDiv Methodology
• Based on user input.– Computes an ideal perforation scheme.– The ideal scheme is transformed from a continuous
function into a discrete function. (pipes with the same perforation rate)
– With the quasi ideal perforation it recomputes:• Pressure inside the pipe.• Flow
– Inside the tube (Q)– From the tube (Outflow) and to the tube (Inflow) (dQ/ds)
Main Features
• Selective perforation for completion of:– Oil Production wells.– Water Injection wells.– Stimulation wells.
• Capable of:– Determine the ideal perforation for a given pressure / flow rate input.– Determine the resulting in/outflow for a given perforation.
Main Features
• The adopted perforation rate can be edited by the user– Check existing configurations.– Check possible behaviors for different scenarios.– Fine tunning according to user experience.
• With the same perforation, the user can change the operation flow rate and check the behavior with that perforation scheme.
