Application brief
Brookfield's TT-100 ® and TT-200 ® online viscometers have long been known . Effective fracturing can increase the production of old wells and new wells. During the fracturing process, real-time viscosity to ensure proper rheological properties. Under pressure up to 20,000PSI, the fracturing fluid or The gel suspension can break the surrounding rock formation, release suspended sand or proppant into the pores or fractures to increase the porosity and increase the production of oil and gas drilling on land and offshore.
The oilfield service industry is increasingly using Brookfield on-line viscometers for real-time viscosity measurement, and the market for on-line instruments is growing faster and faster.
Problem Description
Through effective fracturing operations, the porosity of the downhole can be increased, making it easier for oil or natural gas to overflow. Therefore, under low shear conditions, the viscosity of the fracturing fluid needs to be high enough to suspend and carry the proppant into the downhole to minimize At the same time, under high shear conditions, the viscosity needs to be low enough to allow sufficient flow into the fracture while releasing the proppant. In most drilling operations, field engineers use a coaxial cylindrical laboratory viscometer in the field to take samples for testing , which may not be able to detect real-time viscosity changes during mixing and pumping.
solution
Brookfield TT-100 ® and TT-200 ® online viscometers can be on-site to ensure rheological properties of fracturing fluidsMeet the original design requirements:
The online viscometer can obtain the real-time viscosity of the gel under pressure from the mixer to before injection downhole. The online viscometer can perform real-time measurement according to the shear conditions specified by the American Petroleum Institute (API), 511 seconds-1
Viscosity measurement
Brookfield also provides high temperature and high pressure benchtop rheometer PVS to simulate the downhole performance of fracturing fluids. TT- 100 ® online viscometer, connected by pipeline, can be installed in remote places. TT- 200 ® on-line viscometer, through flange connection, can be directly installed on large-diameter pipes or large Water Tanks. Confirm whether you need to use Brookfield TT-100 ® and TT-200 ® online viscometers are very satisfactory instruments if you use Fann series of laboratory viscometers in the field , because Fann series is for laboratory use and cannot be connected to the process for real-time monitoring.
Real-time measurement of mixed fluids, in turn, assures you and your customers that a compliant mixed fluid is pumped downhole, allowing errors to be detected and corrected immediately at any time prior to pumping.

return on investment
A simple fracturing operation costs about $500,000. Buying a Brookfield TT-100 ® online viscometer can
Ensure the rheological properties of the injected downhole fracturing fluid, so that the proppant can play the most effective role in the downhole fractures and pores, and make the fracturing operation more effective.
The industry has the least investment risk.
