... both detrital and authigenic particles are detached. The pressure drop across the overall core and the concentration of the fine in the produced fluid have been measured. We have derived equations for authigenic-fines detachment using the beam theory and the von Mises failure criteria to obtain...

... , 2015 ), and Uzen ( Sparke et al., 2005 ). Carbonates could produce solid particles (e.g. Onaisi and Richard, 1996 ), however, majority of the solid production is from weakly consolidated and unconsolidated sandstones. Therefore, we focus on sandstone formations in this study. Review on Sand...

... Abstract As part of an Equinor technical efficiency programme that was initiated in 2015 to deliver savings and improvements, bridging particles were removed from the drilling fluids of 15 wells on Oseberg Main and instead loss control material (LCM) was used, as required, in some but not all...

... Abstract Permeability interpretation of well logs in carbonates is difficult due to the vuggy porosity and its connectivity and, on top of it, potential formation damage in and around the vugs. Here we perform an experimental study to determine how single and multiple vugs alter particle...

... Abstract The presence of residual oil or gas during fines migration in porous media greatly affects particle mobilization and capture. This paper investigates the effects of kaolinite content on fines migration and formation damage in the presence of oil residual. We carried out corefloods...

... for performance of effective inhibition of asphaltene. Since the plan is to use a high loading of the slow release particles with the proppants, they were characterized using the same methods for proppants recommended by the American Petroleum Institute (API). Two mesh sizes of these particles were characterized...

... conducted to explore the effects of LCM implementation strategies in lost circulation remediation and formation damage control. Different combinations of granular and fibrous LCMs were tested in a permeability plugging apparatus with slotted discs. When LCM particles accumulated at the slots and formed...

Colloids, suspended and nano particles might be captured by the rock while transporting in porous media resulted by various mechanisms such as size exclusion, attachment, straining, gravitational segregation, bridging, and diffusion into deadend pores...

... fractures which depends on particle properties, movement and deposition highly impact wellbore productivity and consequently is crucial in modeling and design of hydraulic fracturing. This paper presents a thorough review of laboratory scale tests performed on proppant transport related to hydraulic...

This work focused on enhancing sized carbonate pills for screen-specific gravel pack and frac-pack applications. Abstract A simple and effective particle-size...

... analytical method of calculating local stress and velocity (near cuttings-bed in annulus) in an eccentric annular flow is derived which makes it possible to estimate the bed height for foam drilling in horizontal wells. Therefore, a new equation for local velocity (critical velocity) to initiate particle...

.... Results of the analytical model are compared with sand production data obtained from lab experiments and Monte Carlo simulations. The PoSD of a gravel pack is evaluated using the discrete element method (DEM). The process includes generating a random close packing of gravel based on the gravel particle...

... in a slot-flow cell and is designed such that the brine stream erodes the particles from the face of the slurry as it is injected. The distance to the screen after the solids injection is minimized to overcome faster settling of larger particles. The constant rate sand retention test method provides...

The structure of the porous rocks as well as the mud cake were modeled using the bundle of curved tubes approach. In addition, the deposition probability of mud solid particles was considered through filtration theories...

It was shown that for mixture of solid and oil particles, the damage approach based on flow of solid suspensions alone doesn't apply and solid particles-oil droplets interaction...
