  • Wells aren’t the same as they used to be

    Historically, cement has been use to provide zonal isolation to ensure well integrity and reduce health, safety and environmental (HSE) risks. However, as wells have become more complex (i.e., deeper, hotter, more deviated, and lower pressured), conventional cementing methods don’t always work due to hole washouts, poor centralization, and fluid incompatibilities. This leads to unplanned remediation costs.

    Choose the most reliable solution

    BHGE has been able to mitigate these costly issues for the past 60 years with an industry-leading annular cement integrity system that is more reliable and more robust than any other stage cementing technologies in the market. Drawing on extensive run history, BHGE technical and engineering experts have developed comprehensive run-in procedures to ensure flawless execution, so operators can achieve proper isolation the first time—eliminating the need for remediation.

    The system includes the patented ISOZONEexternal casing packer (ECP), which provides a seal between the casing and the annulus to block any fluid or gas movement. The pressure-actuated cementing (PAC) valve sits above the ECP to provide circulating ports between the inside of the casing or liner and the annulus, so additional cement can be pumped above the packer. The system maintains the same integrity as the casing, even during fracing operations, and can rotate during run-ins to ream in the hole if necessary. It is also PDC-drillable, for easy removal once the completion installation is finished.
