High pressure process viscometer for oil drilling

The Brookfield PVS Rheometer is an ideal replacement for bulky standard Rheometers, for rapid field viscosity tests which simulate pressurised process conditions in down-hole environments

Field engineers on-site at oil and gas drilling wells need to perform rapid viscosity tests which simulate pressurised process conditions for down-hole environments.

Measurements are typically required on fracturing fluids, drilling muds, cements and oil/water emulsions, all at elevated temperatures characteristic of down-hole conditions.

The Brookfield PVS Rheometer is an ideal replacement for standard Rheometers which are bulky, expensive, and cumbersome to operate in the field.

Engineers managing oil and gas drilling operations can make a serious financial mistake (perhaps as much as USD500,000) if the viscosity specifications of fluids pumped down-hole are incorrect.

This complicates testing procedures, increases the risk of costly errors and wastes time.

Consequently, it's necessary to ensure fast, accurate viscosity measurement, data collection and analysis of small fluid samples (tested under pressure and elevated temperatures) before they are pumped down-hole.

The portable Brookfield PVS Rheometer offered by Fullbrook Systems gives field engineers reliable viscosity measurement on-site at the well, simplifies complicated test procedures, minimises human error and ensures quality control without delay.

The Brookfield PVS bench-top Rheometer.

* Permits easy relocation to the most remote job site due to its small size and light weight.

* Allows quick and easy viscosity measurements under pressure and elevated temperature.

* Provides complete automation of standard test procedures and conditions.

* Obtains real-time data collection and analysis at multiple shear rates.

* Utilises coaxial cylinder geometry identical to existing standards.

* Allows easy cleaning and disassembly due to simple, straightforward design.

* Isolates torque transducer, bearings and other mechanisms from sample/test environment.

* Minimum vapour space above sample.

* More sensitive than competitive instruments.

Ask yourself the following questions: Do you need to measure fluid samples under multiple shear conditions and at elevated pressure and/or temperature? Are you already using an expensive, large-size rheometer? Or do you use atmospheric "standard" viscometers because the large size and weight of other instruments restricts you from taking the instrument to remote well sites? Do you need to rapidly move a pressurisable rheometer from one remote location to another? Are you building a new mobile test van/truck where the size and weight of the instrumentation needs to be small enough to fit inside? If you answer "yes" to any of the above questions, then the PVS is a good solution for your requirements.

The PVS Rheometer prevents very costly mistakes in the field by insuring that all fracturing fluids, drilling muds, and cements meet viscosity specifications before being pumped down-hole.

It reduces the risk of procedural errors attributable to operator haste.

The compact size, light weight and portability quickly allow the PVS Rheometer to be set up rapidly and perform real-time tests on multiple samples in virtually any location, even the most remote job site.

A complete software package is included in base price, eliminating the need for further development to make the system operational.

It is less susceptible to dust compared to other field instruments: with a choice of cylinder geometry, it allows duplication of standard test methods, and better sensitivity allows measurement at much lower shear rates than previously available from other test instruments.
