Measurement and Testing 43 Increased Hydraulic Fracturing Means Growing Need for Hydrocarbon Testing
Most of the environmental issues related to hydraulic fracturing are focused around water — the amount used and potential contamination of ground water. Noise, dust, traffic and road degradation from the over 2000 trucks servicing a drilling site in a year is also an issue. Reducing incoming and outgoing water to a well site through reuse or recycling would satisfy both the fear of using up public water supplies as well as truck traffic issues.
The most widely-used method to deal with frac water or produced water is reinjection into disposal wells. Recycling/reuse is increasing in arid areas where fresh water costs are high and citizens are protesting the depletion of aquifers. For example, the Railroad Commission of Texas has adopted new rules making it easier for drill site operators to recycle. A bill for mandatory recycling was introduced to the Texas Legislature in April 2013 via House Bill 2992.
Other options for wastewater management include off-site treatment facilities, evaporation ponds, reuse for hydrofracking or treatment for surface discharge. For all of these options, there are maximum levels of oil that will be accepted. Testing to ensure the oil removal system has attained the desired level is an important part of frac water management.
Portable infrared analysers, such as the InfraCal Oil in Water Analysers from Wilks (USA), have been providing drilling operators with the assurance that oil levels are below the required discharge limit for over 50 years, while eliminating the wait for off-site lab results. In hydraulic fracturing, oil in water testing becomes more critical if membrane technology is used to remove TDS (Total Dissolved Solids) as oil will quickly foul the membranes. The new InfraCal 2 Analysers, recently introduced by Wilks, have the added feature of multiple calibrations. This is beneficial to operators that would like to test higher hydrocarbon levels found in drill cuttings, as well as part per million (ppm) levels required for oil in produced water testing.
All InfraCal Analysers provide quick and simple on-site infrared oil and grease measurements to help operators at a well site optimise frac water treatment procedures, maximise evaporation pond efficiency, comply with off-site disposal requirements of wastewater and drill cuttings, or assess soil contamination.

The new InfraCal 2 Analyser, recently introduced by Wilks (USA), for biodiesel in diesel measurements offers additional features to the already established and widely-used InfraCal Biodiesel Blend Analyser. These features include better repeatability, multiple calibrations, unlimited data storage, optional internal battery pack, touch screen display, and password protection for instrument settings.
The InfraCal 2 incorporates new electronics providing a better signal to noise ratio that improves the stability and repeatability. The calibration scheme makes it easier to get an accurate zero which contributes to more repeatable readings. The analyser’s multiple calibration capability enables users to have calibrations for numerous types of diesel fuel, making measurements even more accurate on different feedstocks.
The InfraCal 2 Analyser provides a virtually unlimited amount of internal data storage. For users testing fuels at different locations or at a remote loading rack, data can periodically be transferred serially or via a flash drive. The internal battery pack will last up to 12 hours bringing portability to a new level and eliminating the need to ship samples to a laboratory and wait for results.
The touch screen of the InfraCal 2 allows for features such as password protected calibrations and instrument settings, as well as tagging each measurement with analyst, location and date/time information.
