Abstract: Downhole annulus multiphase fluid monitoring during drilling is technically tricky, and the existing downhole overflow monitoring means the specific overflow type and state cannot be ...

Abstract: Due to the advantages of radiation free, low equipment cost, and high sensitivity to the gas-liquid interface, ultrasonic tomography (UT) has been considered an effective sensing technique ...

This code implements a steady-state drift-flux model for simulating multiphase (liquid and gas) flow in wells. Three-phase flow (gas, oil, water) is supported by treating the oil and water as one ...
