INCLUDED SERVICES

Northstar Drillstem Testers is continually conducting research to expand our suite of services to add value to our clients’ operations.

Closed Chamber Testing

Is conducted with the tool string in the hole and the surface valve closed to create a closed chamber of known volume. This method allows for the calculation of the volume of fluid inflow as a function of time by monitoring surface pressure. Closed Chamber testing allows you to measure the smallest flow rates with pinpoint accuracy. Flow rate and pressure data are calculated to 1 kPa providing increased flow rate accuracy. By eliminating flaring, a Closed Chamber test offers the additional benefits of added data security, minimized environmental impact, and safety.

Closed Chamber Testing is available on all tests at no additional fee.

Northstar Report!
