Zonal Isolation Market to Witness Exponential Growth by 2024
Traditionally,
cementing technique has been used by operators to provide zonal
isolation throughout the life of a well. However, in the past few
years, several mechanical and chemical techniques have been developed
to prevent cross flow of water, gas, or oil between different
formations. Mechanical zonal isolation consists of the use of several
mechanical equipment such as sliding sleeves, packers,
perforated/slotted liners, and plugs. Chemical zonal isolation, on
the other hand, comprises the use of polymer gels, monomer systems,
bio polymers, and elastomers.

Report Overview @
Multiple
technologies along with primary and remedial cementing are deployed
by well operators for isolating a particular zone during well
completion and intervention. Deployment of such techniques depends on
several well parameters such as type of producing zone (oil or gas),
depth of well, wellbore geometry, and temperature of the wellbore.

Zonal
isolation is considered very critical for developing unconventional
resources. It is very essential to predict flow rates to successfully
design and implement multistage hydraulic fracturing in low permeable
shale gas reserves. Cost of isolating a particular zone is generally
2%-5% of the total well completion cost. Shift of exploration
activities from onshore to offshore areas coupled with increasing
focus toward the development of unconventional reserves has spurred
the market for the zonal isolation across the globe.
The
zonal isolation market has been segmented on the basis of technology
and application. Based on technology, the market has been segmented
into mechanical and chemical zonal isolation. However, on the basis
of application, the market has been segmented into offshore and
onshore zonal isolation. Chemical zonal isolation holds the highest
market share in terms of technology. However, in terms of
application, offshore zonal isolation holds the highest market share.
Key players in the zonal isolation market are Schlumberger Limited,
Superior Energy Services, Inc., Weatherford International, Baker
Hughes, Inc., Halliburton Company, Nabors Industries Ltd., Trican
Well Service Ltd., Expro International Group Holdings Ltd., Aker
Solutions ASA, and Tendeka.
