Asphaltene Deposition Study
An Asphaltene Deposition Study's purpose is to determine the asphaltene deposition rate during oil and gas production in well tubings. The asphaltene deposition rate from the fluid is first determined using existing field data from a field well. Then, the determined asphaltene deposition rate of the well is simulated in order to tune AsphWax's asphaltene deposition simulator, i.e., the WELLModelR (if field-specific data are not available, the simulation is done a priori using data from other fields). The asphaltene deposition rate of other wells in the field is simulated next with the tuned WELLModelR. The asphaltene deposition rate is utilized to evaluate the need for well interventions and chemical treatments.
An Asphaltene Deposition Study is a continuation of the Asphaltene Phase Behavior Study and it involves a sequence of tests and computer simulation leading to the determination of the asphaltene deposition rate in tubings. The flowcharts below give a summary of the steps required to:
