Permanent Downhole Gauges

Rely on real-time downhole data to identify reservoir trends, and react quickly to optimize production—without costly well interventions.

Distributed Permanent Measurement Systems

See small downhole problems before they turn into big problems, with distributed temperature sensing (DTS) and distributed acoustic sensing (DAS) systems.

Pressure transient analysis (PTA)
Early water breakthrough requires you to balance choke adjustments with the stimulation treatment. WellWatcher Quartz premium high-temperature, high-resolution PT gauges can be placed in a well to provide PTA workflows. These workflows reveal changes in skin and can be used to determine the productivity index (PI) of the well. Understanding the changes in PI enables you to take the necessary steps to optimize production over the life of the well.
Inflow profiling
In fields with stacked reservoirs, where pressure, permeability, and oil and gas characteristics vary greatly between layers, WellWatcher BriteBlue multimode DTS fiber can be run to provide inflow profiling of individual zones. Downhole flow control valves can then be used to manage individual zones independently, without costly intervention.
ESP management
Downhole pressure and temperature measurements obtained with WellWatcher Sapphire PT gauges can be combined with ESP surface parameters, such as variable speed drive frequency, to prevent deadheading, which often requires a costly workover and ESP replacement. The data can also be used to troubleshoot other common ESP scenarios that reduce well productivity, such as scale deposition above the pump and loss of pump submergence.
Unconventional well stimulation
Using WellWatcher Extend high-resolution dual-sensor PT gauges in unconventional oil and gas wells to monitor bottomhole pressure helps in identifying significant changes to skin, degradation of fracture size and conductivity, and stress-related permeability behaviors. Proactively analyzing the data enables you to monitor drawdown during production and the health of the fractures, both of which are important for long-term well performance.
