Pumping schedule gets acid past damaged zones and generates wormholes. Malaysia is a significant gas producer and liquefied natural gas exporter within the Asia-Pacific region. Many of the country's gas fields are offshore with carbonate reservoirs. The exploitation of these resources involves drilling horizontal wells for maximizing reservoir contact and hydrocarbon drainage. Many of these wells experience drilling mud damage. One of the challenges in stimulating long horizontal wells with openhole completions is the placement of stimulation fluids for effective zonal coverage and generating wormholes to pass the damaged zone. Placing gelled acid through coiled tubing (CT) has been the standard industry practice to clean up a well bore, but due to the low pumping rate, stimulation results have been limited.
