Growing exploration activities, especially in the offshore areas coupled with the recent revolution in shale gas production have boosted the global market for zonal isolation. Zonal isolation is one of the most critical parts of the well completion and intervention activity. It is used to isolate oil or gas producing zone of the well from its surroundings by restricting the cross flow of oil, gas, and water. Well operators use numerous techniques for isolating a particular zone. Traditionally, cement is filled between casings and well bore 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 can be done using different types of packers, plugs, and liners whereas chemical zonal isolation requires several monomers and polymers. Well operators generally deploy multiple technologies along with primary and remedial cementing for isolating a particular zone during well completion and intervention. Adoption of any of the above 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. Cost of zonal isolation varies significantly for different types of zones. Generally it is 2%-5% of the total well completion cost. While analyzing the pricing trends for different mechanical and chemical zonal isolation technologies, it was evaluated that prices for the chemical zonal isolation technology are highly volatile.
This is due to the fact that prices of crude oil have direct impact on chemicals used for zonal isolation. Increasing exploration activities, especially shale gas in countries such as the U.S. have substantially augmented the demand for zonal isolation. Well operators are using several zonal isolation technologies, such as packers and plugs, to mitigate the challenges pertaining to shale gas migration to the surface. Growing offshore exploration and production activities are also anticipated to drive the global market for zonal isolation in the future.

The zonal isolation market has been analyzed in terms of revenue (US$ Mn). Additionally, the market has been segmented on the basis of technology (mechanical and chemical zonal isolation), application (onshore and offshore zonal isolation), and geography. Chemical zonal isolation held the largest share in the global zonal isolation market in terms of technology in 2014. However, in terms of application, offshore zonal isolation led the global zonal isolation market in terms of revenue in 2014.
Geographically, the zonal isolation market has been segmented into five regions: North America, Asia Pacific, Europe, Middle East, and Rest of the World. North America was the largest market for zonal isolation, followed by Europe and Middle East in 2014. The market in Asia Pacific is expected to witness significant growth in the near future due to rapid economic development along with increasing focus toward the development of unconventional reserves in the region. Increasing drilling activities and supporting regulations in several countries, including China and India, are the major drivers of the zonal isolation market. Key players in the zonal isolation market include 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.
