“…For the HTHP dynamic filtration test, the fluid loss volume increased to 115.2, 52.0, 97.6 and 62.4 mL for the four fluids, showing the ability of decreasing HTHP dynamic filtration following the order of OAP > asphaltic additive > modified lignite. The significant increase of fluid loss compared with that of static filtration lies in the fact that filter cake was more difficult to form under a dynamic shear condition [ 49 ]. Overall, the three candidate additives all exhibited effective performance in HTHP filtration control.…”

In order to mitigate the loss circulation of oil-based drilling fluids (OBDFs), an oil-absorbent polymer (OAP) composed by methylmethacrylate (MMA), butyl acrylate (BA), and hexadecyl methacrylate (HMA) was synthesized by suspension polymerization and characterized by Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA) and scanning electronic microscopy (SEM). The oil-absorptive capacity of OAP under different solvents was measured as the function of temperature and time. The effect of the OAP on the rheological and filtration properties of OBDFs was initially evaluated, and then the sealing property of OAP particles as lost circulation materials (LCMs) was examined by a high-temperature and high-pressure (HTHP) filtration test, a sand bed filtration test, a permeable plugging test, and a fracture sealing testing. The test results indicated that the addition of OAP had relatively little influence on the rheological properties of OBDF at content lower than 1.5 w/v % but increased the fluid viscosity remarkably at content higher than 3 w/v %. It could reduce the HTHP filtration and improve the sealing capacity of OBDF significantly. In the sealing treatment, after addition into the OBDF, the OAP particles could absorb oil accompanied with volume enlargement, which led to the increase of the fluid viscosity and slowing down of the fluid loss speed. The swelled and deformable OAP particles could be squeezed into the micro-fractures with self-adoption and seal the loss channel. More important, fluid loss was dramatically reduced when OAP particles were combined with other conventional LCMs by a synergistic effect.

“…The optimal hydrodynamic conditions were established by response surface methodology, maximal permeate flux and the minimal flux decline were observed at TMP 70kPa, retentate flowrate 108 L/h and rotating speed 2800 rpm [44]. DYNAMIC HPHT Filtration system [199] equipped with a rotating cylinder, which could simulate the build-up of filter cake on the formation. A 6.3 mm thick porous walled cylinder (inner diameter of 25.8 mm) as the filter medium and rotating shaft of 19 mm diameter is placed within 250 ml high-pressure and high-temperature cell.…”

“…A ceramic filter (5-90 μm) was used in the MF of the drilling fluid. The experimental results fitted with the Boluk-Balavi equation, which could help evaluate the spurt loss volume, the initial rate of fluid volume loss (flux), blocking and cake erosion in DF [199].…”

“…These works show the technological and economic efficiency of cellulose substances, acrylamide-based reagents, methyl propane sulfonic acid and sodium pstyrene sulfonate, as well as styrene methyl methacrylate-acrylic acid. In addition, an important aspect of the filtering process is its dynamic component, as shown in [17,18].…”

Filtration of the drilling mud is one of it's most important parameters, especially when drilling-in producing formation. Decrease of filtration characteristics allows reducing both solid and liquid phases's penetration zone into the formation. The study of the effect of the weighting-bridging agent's fractional composition on the filtration rate allows selecting of optimal composition of the solid phase in the the drilling mud. This paper presents studies of the static filtration rate of drilling mud with addition of various weighting-bridging agents. The obtained result indicates that an intensive decrease in the filtration rate is observed at calcium carbonate's introduction into the solution with an average particle size of up to 50 µm. Further studies should be directed to investigate the dynamic filtration rate, the possibility of "mixing" of various fractions in the composition of one solution and the evaluation of their influence on the filtration rate.
