... As its most integral equipment, the plant has three ceramic membrane crossflow filtration units (unit A, B and C); each unit accommodates two membrane elements and a backwash system. The plant has also been equipped with a fully automated cleaning in place (CIP) system. During the demonstration...

... Abstract The paper contains numerical simulation of nonisothermal nonlinear filtration in a porous medium. Two-dimensional unsteady problem of heavy oil, water and steam flow is considered. Oil phase consists of two pseu-docomponents: light and heavy fractions, which can vaporize like the water...

... assumptions for the others. Thus, a simulator which can account for poroelasticity, thermoelastcity, fracture propagation, and particle filtration along with two phase reservoir flow in the reservoir domain, is expected to give a more accurate depiction of the involved physical process.

... NPs (NP1) resulted in 20% increase. The optimum NPs concentrations were experimentally identified. A strong relationship between WS and HPHT filtration values was observed. Optical microscopy, scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDX) analyses were conducted...

... The predictions of the deep-bed filtration theory for converging flow, given in Section 6, are evaluated in Section 7, where it is concluded that the converging flow effects are clearly observed in our experiments. The dependence of the deposition profiles on flow rate, particle concentration...

... and the concentration of suspended solids. The EFD is investigating the use of membrane-filtration technologies in the aforementioned aim of waste volume reduction and water extraction from drilling wastes. The investigation involves processing actual drilling wastes using various membrane types and configurations...

... . The experimental work included measuring the rheological properties, thermal stability, API and HT/HP filtration of the three drill-in fluids. The results obtained showed that several polymers can be used to design KCl/Mn 3 O 4 –drill-in fluids. The developed fluid had better thermal stability and filtration...

... of straining of particles smaller than the smallest pore throat in the column, under conditions that exclude the possibility of filtration. The simplest test of a theory is whether it can account for these anomalous observations. Existing theories that consider pore throats as the constrictions cannot explain...

... recorders, and a flow totalizer to record process conditions. This information was retrieved and NTU and SDI measurements ( 2 ) made on the platform on a weekly basis. Demonstrate that cartridge filtration can be used to pretreat seawater to meet SRM filter feed specifications (SDI<5 and NTU<1...

... Abstract This paper describes a method to correct formation pressures measured while drilling for the effects of supercharging (increased sandface pressure caused by drilling fluid filtrate leakoff).The method consists of deliberately varying the wellbore pressure, measuring...

... Abstract The injector impairment due to suspended particles during waterflood project happens in two stages: firstly particles penetrate into a reservoir and are captured by the rock (deep bed filtration); at the second stage, after the reservoir inlet is plugged by particles, the particles...

..., the particle flux is the sum of advective and dispersive fluxes. Transport of particles in porous media is described by an advection-diffusion equation and by a kinetic equation of particle capture. Conventional models for deep bed filtration take into account hydrodynamic particle dispersion in the mass...

... Abstract The majority of the previous models have neglected the effect of the presence of multi-phase fluids in the near-wellbore formation during drilling and hydraulic fracturing. Consequently these studies have used single-phase filtration models leading to the analyses of experimental data...

... Abstract Pressure measurements using conventional wireline formation testers (WFTs) can be influenced by near-wellbore effects such as mudcake buildup and filtrate invasion, which are coupled physical events. These combined effects can change the interpretation of the pressure data, shifting...

Furthermore, clay addition provides good filtration properties with the formation of a filter cake, and this is important in case of accidental overbalanced condition during drilling operation. Lubricity...
