Huff ʹn puff to revaporize liquid dropout in an Omani gas field

In this study, Huff ʹn Puff technique is used as a production mechanism to revaporize liquid dropout in the Saih Rawl retrograde condensate gas field, Oman. During the huff cycle, a number of wells were shut in to achieve revaporization. The same wells were put on stream, during the puff cycle. dropout induced a mechanical skin around the wellbore and hampered gas production capabilities but has been revaporized through pressurization. The pressure buildup in the rich-gas condensate reservoir was due to a cross flow originating from a deeper highly pressurized lean-gas bearing formation. The pressure communication was taken place through the wellbore during shut-in cycles. ositional simulation model was used to confirm the theory of condensate revaporization. Simulation results indicated that Huff ʹn Puff is a viable production technique. The technique improved gas deliverability and enhanced gas–liquid production by minimizing the skin caused by gas–liquid dropout.
