Asphaltene molecules are one of the main sub-fractions of heavy crude oils. During matrix acidizing operation, these polar molecules are highly susceptible to interact with acid and form a third phase called asphaltic sludge. Deposition of the formed sludge on the rock surface and plugging their pore throats alters the rock wettability state and co...

In gas condensate reservoirs, when fluid pressure decreases below its dew point pressure, it contributes to condensate build-up around the wellbore. Due to liquid condensation, gas and condensate relative permeability and mobility significantly drop and well productivity is considerably decreased. Several approaches have been recommended to mitigat...

Asphaltene which cover range of 1% to over 10% of oil by weight, is well-known as most problematic part of oil that can deposit during production in reservoir, well tubing, and surface production lines, and consequently impose a serious restriction on production which in turn increases total cost of entire operation. Through decades an extensive re...

Asphaltene generally existed in colloidal form in cruds and will precipitate in non-equilibrium conditions. Asphaltene instability may take place in the reservoir leading to permeability damage and contributing to flow restriction issues. It may also occur in production strings and surface facilities causing pipe blockage. Any change in oil composi...

Conference Paper
The main point in matrix acidizing treatment optimization is to reduce the skin factor in every single stage of injection and finally reaching the minimum value. If the skin effect owning to damage is quantified, then the treatment must reduce the total skin effect by that amount. Further, to be cost-effective, the injected volume and the pumping t...
