Maximizing Asset Value

through Detailed Sandface Completion Selection

Bryan Stamm

Introduction


Every sand prone field (or well) has its optimum sandface completion from a commercial standpoint.




As a completion engineer, you have many options: – Managed sand production •

Separation and Disposal

– Sanding prevention •

Selective and orient perforating, managed drawdown, etc.

– Sand Control •




Cased hole gravel pack, fracpack, SAS, ESS, OHGP + intelligent completion, etc…

Your job is to investigate the technical and financial aspects of each, and determine which one provides the best value for your company

Geomechanics and Sanding Prediction


Onset of sanding can be modeled – Some wells will sand immediately – Some may never produce sand – Some may sand later in the well / field life




The degree of certainty in sanding prediction is dictated by the quality of the “inputs”…rock strength, drawdown, completion type, wellbore inclination, etc. – Dipole Sonic, Sonic Scanners, Cores, Tectonics, etc




Previous “similar” field experiences or rock mechanics studies should not be used in isolation.
