.... One system only used hematite, while the other used both hematite and Micromax in an effort to eliminate sedimentation issues associated with hematite in geopolymers. The effects of adding Micromax on different FFA geopolymer properties were also evaluated. The study evaluated mixability, rheology...

... rheology of neat fluids and mixtures, emulsion formation tendency, and scale tendency. Contamination of oil-based drill-in fluid with drilled solids, completion brine, and seawater was studied following API-13I protocols. For all other fluids, rheology was measured before and after mixing of the fluids...

... With the development of horizontal wells, more and more projects have applied horizontal wells for heavy oil EOR. Although many simulation studies have been conducted on the rheology model effect of polymer flooding ( Laoroongroj et al., 2014 ; Fortenberry et al., 2017 ; Khamees & Flori...

Rheology All rheology measurements were obtained with a Grace M5600 HP/HT rheometer with a R1/B5/F1 rotor/bob...

... data access, neglect of the physics, and/or use of improper algorithms, such as neural networks which are shown to perform poorly despite their popularity. In this work, we develop a digital twin to calibrate the rigsite rheology measurements for obtaining the API standard properties by exploring...

... Abstract Magnetorheological fluids (MRF) have their rheology modified in the presence of a magnetic field. The MRF consist of a base fluid, magnetizable particles, and a viscosifier that supports these particles. The magnetizable particles align in the direction of the magnetic field, creating...

... a flat rheology over time, allowing better control of the circulating pressures during placement. Laboratory tests show less gelation and an improvement in static gel strength development as compared to current dispersants. The dispersant also provides better rheological properties, often at lower...

The operator was successful in abandoning the seven wells as per the regulatory requirements, with 45 cement barriers put into place. Applying similar designs from one well...

... in the properties of the cement slurry being altered when the two fluids are mixed. Two main properties of the cement can be affected by the contamination of a cement slurry with an SBM. The first is the effect seen on the rheology of the slurry when mixed with a synthetic system. When incompatible fluids mix...

... material with a high surface area to economically displace OBM from the annulus while effectively cleaning the wellbore. The rheology and density of the fluid can be designed to remain stable, therefore preventing settling of the microparticulates during placement. This efficiency fluid can be placed...

.... Depending on the sediment type various rheologies and friction relations can be adopted. Herein we consider a shear resistance derived from a Herschel-Bulkley rheology and a Chezy-type entraining shear relation. The model may be used to predict the spatial and temporal development of a sediment density flow...
