The evaluated gravel pack PoSD is then used to compute the filter efficiency of the pack for various formation sand sizes. Sand production through the gravel pack is predicted analytically...

... of the formation sand in brine. This slurry is then injected into the brine flow-stream to accomplish the desired solids concentration for the test (typically 0.5-1.0%). The method allows for flexibility both in the brine flow-rate used and in the solids concentration tested. The slurry injection is accomplished...

The test method also allows for extended treatment soak times, up to 10 days. drilling fluid selection and formulation drilling fluid property...

... on various formation sands having higher clay content, 5 to 10%, combined with fines ranging from 5 to 15%. The results showed that traditional resin consolidation treatments do not provide acceptable retained permeability and consolidation strength. Using COPs in the preflush provided improved retained...

... are a newly introduced aminopolycarboxylic acid (APCA), pH 2.5 to 3 that contains sodium ions, and an established hydroxycarboxylic acid (HCA) fluid, pH 3, sodium-free. Flow testing was conducted at the anticipated bottomhole static temperature (BHST) of 270°F in synthetic packed columns with formation sand...

... of formation sand samples are also often used to generate "simulated" formation sand for laboratory experiments. The two most commonly used techniques for PSD measurements are sieve and laser, while some engineers use one technique for no obvious or justifiable reasons, others use both techniques...

... Abstract Conventional solvent-based resins (SBRs) have often been used to resolve solids-production problems in producing wells by coating the particulates, such as formation sand, fines, and proppant, with a curable resin to hold the grains together without reducing the treated pack’s...

... of particles on the screen coupon. The PSD of the retained sand approaches that of the formation sand after a few layers of sand accumulates on the screen. · Thus, the screen has no function for sand retention after the first layer of sand particles covers the screen openings. If the experiments...

... screen plugging with clean formation sand is almost never an issue and that the probability of screen plugging due to other factors can be minimized when proper precautions are taken. We propose that screen candidates for standalone screen applications be initially selected based on sand retention...

... Abstract Grain size distribution of formation sands is one of the crucial parameters in a sand control program. Such information is commonly derived from sieve or laser particle size analysis (LPSA) techniques on a limited number of core samples from the target well or from a neighboring well...
