f Chemical Stimulation of Gas Condensate Wells

Gas wells are susceptible to sub-optimal performance due to<br>accumulation of liquid in the near wellbore region of the<br>producing well. This liquid may arise when the bottom hole<br>flowing pressure drops below the dewpoint pressure of the<br>fluid and a gas condensate bank (retrograde condensate) forms<br>in the near wellbore region of the producing well.<br>Alternatively, water may be present from many natural and<br>man-made causes, ie, connate water, water from an aquifer,<br>bottom water, crossflow from another zone,<br>completion/fracturing fluids, etc. In a worst case scenario,<br>both of these situations can occur and cause severe liquid<br>blocking of the gas.
