Drilling fluids / Mud flow measurement
The measurement of the flow rate of drilling fluids is critically important for safe and effective drilling and logging operations. Accurately measuring the balance of the drilling fluids as a system (barrels-in versus barrels-out) provides important information to the driller and mud logger. It gives:
Early warning kick detection - formation fluids flowing into the well bore and up the drill string due to imbalance of hydrostatic pressures
Tracking ballooning and allowing the driller to differentiate between ballooning and kick
Accurate mud flow rate - used by mud loggers to compute transport velocity and lag time (the time it takes for the mud to circulate from the drill bit to the surface)
Bell Technologies' TORUSWEDGE flow meter is ideally suited for measuring the abrasive flow of drilling fluids such a drilling mud.
Significance of drilling fluids Industry measurement challenges
Drilling mud flow measurement can be a very challenging measurement for traditional flow meter technologies. Wide variations in the type of mud (water based, oil based, synthetic, emulsion), the solids content, the type of solids and other factors requires flow meters that have the ability to measure drilling fluids with wide ranges of fluid viscosity, density, conductivity and resistivity.
Variations in drilling operations in terms of depth, rate of penetration, pump pressure and other factors result in a wide range of potential drilling mud flow rates (referred to as "turndown"). Most traditional flow meters are designed for a specific operability range and do not have wide turndown. In addition, flow meters with components that are intrusive into the flow are highly susceptible to wear and damage due to solids, chemicals and cuttings in the drilling mud flow stream. Safety is of course of highest importance in any drilling operation, and flow meters must be designed to operate in high pressures and harsh environments without risk of safety critical failure. These variables make it challenging to find one type of flow metering technology that can be cost effectively applied to a wide range of drilling operations and provide the accuracy that is demanded in today’s high tech drilling operations. Traditional measurement methods To date, measurement of drilling fluids into the well bore has by-and-large been carried out by simple counting of pump strokes to calculate the flow rates. However, this method of calculation raises a number of issues such as:
Human error – risk of miscount, especially when switching between varies pump sizes and having multiple pumps run concurrently
Reactive approach – lack of real time flow rates at the rig control system hinders the driller’s ability to identify potential operational issues or make changes in the system to optimize operations
Drilling mud pump efficiency – counting the pump strokes does not account for physical wear on the pump liner, which can cause differences between theoretical and actual pumping rates

Selective cementing is required in well bores with lost circulation zones, high water pressure, low formation pressure, and high-pressure gas zones. The TORUSWEDGE is currently in use at Weatherford as a cementing calibration tool to help certify all of its down hole cementing solutions.
