... is the transport of the particle slurry from surface to downhole. The aim of this work is to identify the operational parameters dictating the integrity of a particle slug and optimize these critical parameters to ensure efficient diverter slurry transport and fluid diversion efficiency and effectivenes...

... only identifies PSD, dynamic image analysis (DIA) determines physical properties of each single particle. Properties such as size and shape of single particles, aggregates, fractures, and even undersized particles can be detected. Similar to a modern microscope, there is a digital camera with specific...

... is that it allows a "real-time visualization" of individual particles while in contact with CO 2 . Results obtained show the HPHT Visio-cell to be the best fit for assessing the behavior of the tested material. Additionally, some components appear to swell less with CO 2 than others. real time system high...

... Abstract Plugging of cuttings in the wellbore is a common problem during drilling processes. Some authors have analyzed settling or slip velocity of particles in a liquid both analytically and experimentally. The concentration of cuttings throughout the well has been also analyzed. It has been...

... of the formation fines that has been very successful. Modifying The zeta potential to optimum range, provides a strengthened attraction between the particles to optimally align proppant type, sand particles, fines, etc., allowing the formation of conglomerates of proppant, sand, fines, etc., improving...

... CFD-DEM modeling setup considers: constant fluid and particle properties, turbulent flow regime (k-ε model), free slip in internal walls, DEM time step equal to 1 × 10 −6 s, CFD/DEM time step ratio equal to 1/100, particle rate equal to 30000 particles/s, velocity prescribed at inlet...

... nature of the crudes. In this study, the asphaltene precipitation envelope was determined using Near Infrared (NIR) Solid Detection System (SDS), High Pressure Microscope (HPM), Particle Size Analysis (PSA) and gravimetric techniques. As expected, a significant amount of asphaltene was observed...

... Abstract High energy electron particles were utilized to improve the rheological properties of heavy asphaltic petroleum fluids and upgrade them into lighter, and more utilizable, fluids. Heavy oil reserves, as one of the most abundant sources of energy, have attracted considerable attention...

... Abstract Conditions leading to plugging in weak or highly permeable formations and the resulting permeability impairment occurring during flow of suspensions of deformable gel particles are investigated by core flow tests. Effect of concentration, flow rate, and particle diameter of gel...

... Abstract This paper evaluates different environmentally friendly dispersants in invert-emulsion drilling fluids that can be used to drill HP/HT wells. The drilling fluid is weighted by manganese tetraoxide (Mn 3 O 4 ) particles, which have a specific gravity of 4.8 and a mean particle diameter...

... string rotation on the suspension of cuttings, this project is intended to quantify the capacity for suspension of particles from the cuttings bed for different fluids and different sedimentation heights, in cylindrical horizontal wells. Quantifying the suspended mass in the annular geometry of the well...

Abstract Transport of particle suspensions in oil reservoirs occurs during sea or produced water injection with particle capture and consequent injectivity decline, produced water disposal in aquifers and subterranean water contamination, drilling fluid invasion causing formation damage, fines...

... Abstract The use of the alpha and beta wave technique for a successful Horizontal Open Hole Gravel Pack is based upon a well without, or with minimum, losses. In this case, the gravel particles will be adequately carried to the expected point of deposition. So, in case of any mud losses, both...
