Good Agreement

The improved model developed in Part 1 for predicting heat losses and pressure changes in steam injection wells is evaluated. It shows good agreement with limited field data. The improved model is used to predict the effects of steam injection time, rate and pressure, well depth and tubing diameter on heat losses, bottomhole pressure and downhole steam quality. A design example is presented to illustrate the solution method for a common field operations problem.

Pressure Changes

An improved model for predicting heat losses and pressure changes in steam injection wells is presented. The model incorporates a new two-phase, annular-mist flow pressure change model with heat transfer to the surroundings during wet steam injection. The model requires an iterative procedure which is solved numerically using a fourth-order Runge-Kutta method.
