Value of Madala SAGD
The unique Madala SAGD capabilities make the following design, production and operations benefits possible.
SCENARIO 1: RIGHT-SIZE YOUR WELLBORE
Madala SAGD can be used in re-evaluating a field’s heritage phase wellbore sizing for new pads. Leveraging field planning forecasts, the appropriate sized wellbore can be designed.
SCENARIO 2: INCREASE SUCCESS RATE OF STIMULATION JOBS
Madala SAGD can be used to accurately understand downhole pressure profiles. In cases where accurate downhole measurement is not available or is misleading, understanding the true dP across the liner can avoid mis-selection of acid stimulation candidates.
SCENARIO 3: OPTIMIZE PRODUCTION FROM EXISTING WELLS
Madala SAGD can be utilized to find optimal set points or directives for well operating parameters such as pump speed, gas lift injection rates and surface choke settings.
SCENARIO 4: WORKOVER DESIGN OPTIMIZATION
Madala SAGD can be utilized to discover root causes of poor performance in wells and evaluation of remediation options. For example:
- Under-sized wellbores for actual fluid rates lead to steam coning inside the horizontal section, ultimately restricting potential production and reducing pump run time. Possible solutions include removal of long string or tail pipe to reduce pressure drop causing steam flashing.
- Evaluation of failure fixes such as patches, scab liners or inflow control devices:
- Assist in comparing the different repair techniques.
- Reduce costs by appropriately sizing piping and ICDs for the selected repair.
SCENARIO 5: Reduce production engineering effort to reach correct decisions while increasing accuracy
Madala SAGD’s built in workflows for configuring simulations is highly tuned for SAGD production engineers. What used to take days or weeks in other tools can be accomplished in minutes or hours in Madala SAGD. In addition, once configured, simulations run in seconds to minutes versus minutes to hours.
SCENARIO 6: INCREASE PUMP RUN LIFE
Madala SAGD allows operators to assess the impact of operating conditions, well bore sizing and trajectory on downhole pump performance. In doing so one may identify:
- Optimal placement of a downhole pump with respect to the trajectory.
- Optimal sizing of additional equipment, such as tail pipes or instrumentation strings, to reduce friction that may cause steam flashing within the wellbore. Calculation of steam flashing in all sections of the wellbore allows for reporting of excess steam hitting the pump inlet affording production engineers the opportunity to take action before it is too late.
- Early discovery of poor pump performance by contrasting actual observed pressure profiles to simulated profiles.
