ABSTRACT: Water manufactured is the
primary waste source in the oil and gas industry. Because of the rising amount
of waste worldwide, the environmental effect of wastewater has become a primary
environmental concern in recent years. The vast amounts involved have resulted
in considerable costs to the industry for handling produced water. This
research explains the wide variety of choices for water management. This
research’s first phase was water minimization techniques, consisting of three
different applications made in three different wells (Well 1, Well 2 and Well
3) and water recycling and reuse by two techniques. In Well 1, Mechanical
shut-off technique was applied using through tubing bridge plug and 5 m cement
dumped above it to isolate the watered out zone; as per water oil ration plot
the water cut is decreased from 100% to 4% and the production is increased from
0 to 400 bcpd. In Well 2, Chemical shut-off technique using a polymer called
Brightwater has been used to block channeling through high permeability
intervals after PLT log detected it, and the result was brilliant, the water
cut decreased from 60% to 25%, also the oil production increase from 500 to
3000 bopd. In Well 3, downhole separator installed in it using workover (unfortunately,
this technique is not applied in middle east till the moment so this
application is taken from an oil field in Canada)and the result was perfect,
the water cut decreased from 70% to 28%, also the oil production increase from
44 to 100 bopd. This study tried to clarify and compare the most widely used
water management techniques using one of the Western Desert (W.D.) (enhanced
for oil recovery, constructed wetland).
