Abstract
The likelihood of sand production plays an important role in the selection and application of completion solutions like open holes, screens or perforated liners.
The paper will present a new sand production model. The model is also valid for wellbore collapse during underbalanced drilling. It is based on a full 3-dimensional analysis and takes load history into account. The model is derived for anisotropic stresses and is valid for all wellbore orientations. One interesting observation is the importance of the cohesive rock strength for stability in the depleted phases of the reservoir.
A field case investigates the sand production potential for vertical and horizontal wellbores. The second case investigates effects of in-situ stresses and rock properties in a vertical well.
