Frac Flowbacks – After a well has been stimulated by fracturing or acidizing the well stimulation fluids (frac sand, acid and other chemicals) can be safely recovered from the wellbore into the P-tank (Pressure tank) before the well is put back on production. The sand, acid or other chemicals will be separated from the gas and trapped in the tank. The gas will be flared to a flare stack.
In some location internationally the frac can be flowed back through a HP choke manifold system and / or through a HP sand catcher system and all the well effluent usually gets flowed to a pit.

Well Bore Cleanups
– New wells typically need to be flowed to cleanup the well before putting it on production. The cleanup will remove all drilling or completion fluids left in the well. In certain location internationally, the well can be cleaned up to the pit where all the well effluents can be flared off (desert testing).

Single Point or Multi-rate Tests
– These are well deliverability tests that involve flowing the well through a series of chokes, flowlines, separators and meters to obtain a stabilized flow rate. They can be either a single rate test or can be multiple rate tests. The backpressure can be adjusted to simulate the effect of flow line pressure on the well. This information is useful in designing the surface facilities and pipeline for the well or field.

Drawdown & Buildup Tests
– These tests are used to determine information about the reservoir. Drawdown tests are used to determine the size of the reservoir. These tests usually involve multiple flow rates that have a shut-in period between rates where the pressure buildup is monitored.

In-line Testing
- These tests can be performed provided the flowline pressure is less than the rated separator MWP. Our separators are provided with a provision of combined outlet lines tee’s for easy and quick rig up and rig down during in-line testing.

Vapor Recovery
– During well completion and workover operations there is typically a need to dispose of the hazardous gases from the well. To minimize the risk from the toxicity of H2S gas or the flammability of sweet gas, it should not be vented to the atmosphere through rig tanks as was done in the past. The well can be flowed through the P-tank (LP sand separator) where any liquids are separated out and then the gas can be safely flared out to a flare stack.

Memory Gauges –
Henka uses a full line of Quartz and Piezo-Resistive memory gauges and they are available for most pressure and temperature requirements, in 0.5", 0.75", and 1.25" outside diameter. Applications include Slickline, Coiled Tubing, and Frac markets. These tools are characterized by their durability and ease of use. Henka’s memory gauges continuous bottom hole pressure and temperature monitoring system consists of modular components engineered to match any reservoir monitoring application or budget. Common applications include long-term reservoir analysis and automated reservoir optimization solutions.

Data Uploading
: Henka utilizes Sunergon Information Services, Inc. Wellpost for data uploading services. Wellpost is designed to transfer oil field data and post it online. Data transfer is fast, secure and convenient with smart data transmission tools provided an internet connection is available.

Data Acquisition:
Field application inputs or transducers are routed via the Cable System into the Scanner® 1131where analogue to digital conversion, pulse counting and the addition of a stable and accurate real time source takes place.
ScanWin LITE is a software application Henka uses to perform all functions necessary for measurement applications including flowrun data downloads.
