This paper discusses a probabilistic flux and erosion model and work flow that extend the ability to estimate inflow through sand screens on a foot-by-foot basis along the wellbore using the well’s completion details, production rate, and reservoir and bottomhole flowing pressures. The model is then calibrated and history matched using well data from pressure transient analyses, well tests, and production logs as available. Extensive laboratory testing coupled with computational flow dynamics modeling provided the algorithms for different screen types to relate flux and sand production to the expected service life for any given future production profile. This allows the well’s planned production profile to be optimized by balancing risk, rate, and reserves recovery.
Introduction
The flux management work flow was field trialed on various failed and successful sand-control completions and has been used on many wells subsequently.
