Presentation Transcript

  1. CYDAREX • created with IFP, now 100% R. Lenormand • software CYDAR • design and interpretation of SCAL experiments • measurements on drill cuttings • porosity and permeability • consulting SCAL

  2. CYDAR • Design and interpretation of laboratory experiments • can be used by technicians • Windows environment • pre-programmed experiments • use of more recent models for interpretation (SCA publications) • customized reporting

  3. CYDAR Modules • MERCURY • PERM: monophasic permeability • KrUSS (Kr unsteady-state) • SteadyState (Kr steady-state) • CENTRI (Pc et Kr by centrifugation) • TPF (Two-Phase Flow) Modules can be run separately

  4. main features • Data Input • ASCII files, clipboard from Excel • opening of experimental files • Data fitting and smoothing (Splines) • Export graph and tables • Reporting

  5. 1 - MERCURY • direct opening of the ASCII file generated by the experimental apparatus • data smoothing by spline functions • first injection, withdrawal and second injection • calculation of 3 types of pore size distributions • permeability estimation • reservoir Capillary Pressure

  6. 2- PERM: Monophasic Permeability • liquid and gas • steady-state • unsteady-state (pulse decay) • inertial effects • Klinkenberg correction • pressure drop in tubings

  7. 3 - KrUSS: Kr by unsteady-state method • direct simulation for design of experiments • experimental data treatment • filtering large experimental files • dead volume correction • analytical calculation • JBN • Jones and Roszelle • history matching • using effluent, pressures, saturation profiles • manual or automatic • reporting • customized • pdf or excel files

  8. 3 - KrUSS module Infos (sample, well ...) Sample and fluid properties Experiment data blocTimes Numerical optimization Analytical JBN , Jones & Roszelle Design Load/edit data dead volumes corrections assumed Kr/Pc Load/edit data dead volumes corrections Pc Numerical simulation JBN calculation Kr first guess or JBN Experimental vs. simulated History matching Experimental vs. simulated reporting (pdf or excel)

  9. 4 - SteadyState: Kr/Pc by steady-state method • direct simulation for design of experiments • experimental data treatment • filtering large experimental files • dead volume correction • analytical calculation • assuming uniform saturation • history matching • using effluent, pressures or/and saturation profiles • both Kr and Pc determination • manual or automatic • reporting • customized • pdf or excel files

  10. 5 - CENTRI: Kr/Pc using centrifugation • direct simulation for design of experiments • experimental data treatment • filtering large experimental files • extrapolation for steady-state production • Pc determination • Hassler-Brunner • improved methods (Forbes and Splines) • Kr determination • analytical calculation • history matching

  11. 6 - Two-Phase Flow • Direct simulation of Two-Phase experiments • 1 or 2 fluid injection • Semidynamic method • Spontaneous displacements • Gravity flow • Centrifuge displacements, • Porous plate

  12. customized modules • Real time data acquisition • DARCYLOG (cuttings, IFP) • PDOS (Pulse Decay with Open Surface, IFP) • Centrifuge (Vinci-technologies) • Customized experimental input files (MICP) • customized corrections • pressure offset, • inlet and outlet dead volumes, • temperature correction, • etc
