Additive Injection in Well Field using Wing Nut Industry

Oil and Gas Field Services – Turbine flowmeters, meter liquid and gas additives

SIC Code

1389

Application

There are several companies worldwide that provide oil and gas well field services. One of the services offered provides for enhanced output from the well. The service company injects various additives into the wellhead. Turbine flowmeters are commonly used to meter the liquid and gas additives. A specific application identified by Dowell Schlumberger of Sugarland, Texas, is for monitoring high-pressure gaseous nitrogen at 0 – 10,000 PSI pressures. During the injection process, Dowell Schlumberger monitors several process variables to improve the well’s output ultimately.

System Requirements

Accurate overpressure range 0 – 10,000 PSI.
Rugged to withstand harsh field conditions of oil fields.
Lightweight for transportation between sites.
Totalize output of nitrogen gas in mass units.
Provide compensated analog output for the data acquisition system.

Solution

Hoffer Flow Controls and Dowell Schlumberger have designed a metering skid that incorporates a turbine flowmeter and mass flow computer. The skid consists of the following:

–Wingnut turbine flowmeter designed for pressures up to 15,000 PSI.
-Wingnut housings to accommodate the installation of high-pressure temperature and pressure transducers.
-Mass flow computer.
-Aluminum frame supports the meter run and is used to carry the meter run.
-A manifold collector box that accepts independent signal inputs from flow meters, temperature transmitters, pressure transducers. The collector box provides one cable assembly that carries all process signals to the remote mass flow computer.

Hoffer Advantage

Wingnut turbine flowmeter is rugged and designed for oil field conditions. Flowmeter provides a wide operating flow range that is usable over the wide operating pressure range. Mass flow computer provides mass flow calculations and corrects for temperature, pressure, and compressibility. Flow computer incorporates “high alarm” to monitor flow rates that could occur over the turbine flowmeter range. Flow computer improves flowmeter linearity via linearization

Summary

The flow system allows the customer to monitor mass flow during the good treatment accurately. Based on the information obtained from the system, they can adjust the treatment of the wellhead to provide for optimum product output.
