.... Operational and mechanical factors that were empirically found to result in sand production were identified. The sand‐production model was run to verify the role played by different factors. It is shown that completion design, rock strength, and post‐failure behavior of the rock are key factors responsible...

... and by determining their role in maintaining structural strength. Several PPG hydrogels were prepared by varying the concentrations of polyacrylamide and chromium triacetate [Cr(OAc) 3 ] as copolymer and crosslinker, respectively, using a central composite design. The characterization of these hydrogels...

... reported for comparison. Isolation quality is evaluated through permeability tests, performed both parallel and perpendicular to the macroscopic bond interface. For shale, we propose a surface treatment before plug placement that also prevents plug displacement under differential pressures. Strength...

Engineers Metallic materials or metals are used in an ESP system for their mechanical strength to carry load (tensile, compressional, and torsional), abrasion/corrosion resistance, and electrical/thermal conductivity. The study of metals is a specialty area of material science. The classification...

Results show that the mature Cr 3+ /KYPAM gel can withstand positive pressure of 10 MPa for a period of 120 minutes with average fluid-loss volume of 15 cm 3 for the core...

... is consistently larger than the manufacturers’ published R -ratios. This paper presents a discussion of the factors affecting the R -ratio and an explanation for the difference between published and tested R -ratios. The R -ratio is not a constant but varies with dome pressure, port-material strength, bellows...

...) to remove gel cakes induced during conformance-control treatments. The interactions between HCl and PPG were evaluated to understand the swelling, deswelling, and gel strength after adding acid. A Hassler core holder was then used to determine the core permeability after gel and acid treatments. Gels...

The polymer skeleton covered by crystalline ammonium salts can increase the gel strength and salinity tolerance as a result of the unique structure of “crab's big claws.” The gelation performance is not seriously affected by the shearing effect...

It achieves twice the baseline conductivity of any conventional proppant at these high stresses, and should also provide additional advantages because of increased durability. This paper...

... for degradation of proppant over time has recently been postulated. This mechanism has been labeled "diagenesis" and refers to a dissolution and reprecipitation process that may reduce the porosity, permeability, and strength of the proppant pack as precipitants are deposited.

... in. The hardness or strength of core samples was measured before and after acidizing, using the RES method ( Howard and Fast 1970 ). RES was measured using a ball point with a 0.0625-in. diameter that was mounted on the upper platen of a hydraulic testing machine. During the test, the ball point was brought...
