Unconventional Surface Well Testing

The Bear Cyclone Separator uses a newly developed Gas-Liquid Cylinder Cyclone (GLCC) technology that greatly reduces size and pressure drop compared with standard separators. The GLCC are designed for various levels of well performance. The momentum of the inlet process fluid generates a liquid vortex that allows sufficient gas and liquid separation to rapidly occur. This process creates dryer gas, lower pressure drop, and generally leads to a smaller equipment footprint.

Advantages;

• Very high efficiency. low cost and compact size
• Very small operational footprint
• Low pressure drop means more production
• Superior separation leading to better gas and liquid measurement
• Diameter of manufactured vessels can be built to suit, from 3” to 36”
• Low maintenance systems

Technology Applications;

• Control of GLR for multiphase flow meters and pumps
• Primary surface separation and measurement system
• High pressure separator for wet gas applications
• Portable system for well testing purposes
• Low API Gravity Application (12 API)
• First Stage Gas Compressor
• Flare Gas Scrubber
• Steam Quality Metering

Surface Well Test Data Acquisition

FarleyRiggs PEAK is an advanced well test data acquisition solution designed to maximise data recovery during well test activities. The human element of acquiring accurate manual data parallel to acquiring accurate electronic data is paramount to delivering a complete data solution.

PEAK delivers the assurance that data acquired during the test is complete and accurate enabling instantaneous calculation of rate data.

The ability to trend real time data delivers the added benefit of being able to instantaneously assess well performance. Trending is also an important tool to enable potential problems to be dealt with at an early stage of recognition.

Surface Acquisition System Specification;

• 10 Channel Wireless Data Logger
• Pressure, Temperature, Differential Sensor Compatible
• Electronic Flow Meter Compatible
• Historical Data Re-Calculation
• Intrinsically Safe
• Alarm Configurable
• Local Area Network & Wide Area Network Compatible

Surface Data Acquisition System Features;

• Real time acquisition of multiple data channels that enables continuous data acquisition, accurate rate calculation and data trending which can be then used to accurately analyse well performance.
• Ability to set alarms to monitor parameters in real time increasing safety performance.
• Increased versatility related to data presentation enabling accurate trend analysis.
• Capable of remote delivery of data to client desk.
