PetroGuard ® Advanced Mesh Screen
PetroGuard® Advanced Mesh Screen
What is the driver?
Current standalone screens have exhibited: Questionable performance
Ratty or poorly sorted sands Heavy oil
Room for improvement regarding longevity in SASRoom for improvement regarding longevity in SAS completion conditions Susceptible to plugging in high fines content reservoirs Relatively low dirt retention

Design Constraints and Considerations
Maintain filtration efficiency Handle a wide range of particle sizes and solids concentrations
Damage tolerant Mechanically robust
Reduce design option limitations Reduce design option limitations Limited number of micron ratings Combine different weave types, if necessary

Goals of New Screen Design Increase dirt-holding capacity
The amount of solids that can build up on a filter before an excessive pressure drop is seenexcessive pressure drop is seen
High-plugging resistance Dramatic increase in life span, particularly in heavy oil
completions
Maintain mechanical integrity Design variability for each individual well or field Design variability for each individual well or field
Rapid design methodology and testing

Design Concept to Improve Retention
Use multiple layers of mesh Design number and rating of layers for a specific
particle size distribution Place larger pore mesh on the outside; finer mesh on
the insidethe inside Each layer filters smaller and smaller particles Final filtration mesh flow area is reserved for retention
of appropriate reservoir particles

Depth Filtration
Largely discredited due to old style materials Typically a media with non-uniform
pore structure Pore size control is virtually
impossible Tortuous production path Difficult or impossible to clean (back-
flush)

PetroGuard® Advanced Mesh Filtration
A completely new concept Uniform pore structure Initial filter layer
within each layer Pore size control is
very precise
Coarse filter layer

Conclusions
Concept works for heavy oil wells. Concept also works for conventional wells, not just heavy
oil. The higher the PSD uniformity coefficient and/or the greater
the percentage of fines the better the concept worksthe percentage of fines, the better the concept works. Applicable for SAS type completions but may also be used
in GP completions. Suitable for PoroFlex® expandable screen application
