Formation Sampling and Sand Analysis
The starting point for any kind of sand control with respect to geomechanical approach is proper sampling and sand screen analysis. Use of bailed or produced sand samples leads to mistakes and problems and is the poorest kind of data that can be used in designing sand control. The representative samples are obtained by coring the whole length of the interval with adequate coring equipment. Particle size distribution is then determined through sieve and laser particle size (LPS) analysis.
LPS is used to determine the amount of fine particles that exist due the swelling and migration of bonding clays, or due the crushing during production.
Such analysis is the basis for proper design of liner openings, screens or gravel pack sizing.
