Abstract
|
The wettability alteration is one of the important
mechanisms to increase the production of oil and gas
reservoirs. One of the methods to wettability alteration is to
have nanoparticles in contact with surfaces or injected into
porous media.
In this study, the effect of alumina nanofluids on the
wettability alteration (oil and condensate wet) of a
carbonate rock was experimentally studied. Alumina
nanofluids with different concentrations in the range of
0.001-0.01 wt% were prepared and the size of particles into
the nanofluid was analyzed by the particle size analyzer and
found average 13 nm.
The effect of nanofluids on the wettability were investigated
by measuring the contact angles of water/oil/rock and
water/condensate/rock systems. Results show that the
contact angle is changed from condensate and oil wet to
water wet in water/oil and water/condensate system
respectively, and from gas-wet to strongly gas-wet in the
water/air system.
