... onto the rock and altering the formation wettability from water-wet to oil-wet thus diminishing the effective permeability to oil, k o , and c) increasing the reservoir fluid viscosity, μ o , by nucleating water-in-oil emulsions. In the most frequently encountered case of asphaltene-induced formation...

... maintenance. However, present studies focus on GLCC designs and applications at relatively lower gas velocities (below the minimum velocity for onset of liquid carry-over in the form of annular/mist flow). With appropriate modifications, GLCCs can be used for wet gas (high gas liquid ratio, GLR) applications...

... within the body of the slug. The foregoing trials were repeated with an intermediate-viscosity fluid to see whether this was a sufficient reduction in viscosity to facilitate transport. For these tests, a 150-cP carboxymethylcellulose solution was used. In addition, both water-wetted and dry sand...
