Flowback Water Management

One cubic meter 6 3 bbl of water requires 3 3 gj 2 2 million btus of energy to evaporate however the value of energy known as exergy depends on its temperature.

Flowback water management.

There is much less water produced from shale oil production compared to that from conventional oil production. Fracking companies across the nation use a multitude of methods for disposing of the flowback water they produce. The fluid produced during this phase is a mixture of crude oil natural gas water and sand. Millions of gallons of water along with hydrochloric acid and other chemicals are injected during a frac job.

Dependent on each state s regulations for disposal energy companies often have three different methods to choose from. This water based solution consists of chemical additives mud clay dissolved metal ions and tds total dissolved solids. Flowback is necessary for initial well cleanup to remove fluids that were introduced to the well and any debris that accumulated in the wellbore. It may only make sense to spend this energy if a waste heat source or a low temperature heat source is available such as waste heat from reciprocating engine jacket cooling exhaust or waste gas that is flared.

Flowback water the second type of water results from the fracture stimulation frac the process whereby freshwater is pumped into the wellbore under extremely high pressure to fracture subsurface rock formations to release hydrocarbons from the producing zone. Our water treatment team utilizes a spectrum of bio control and recycling technologies to prepare source water to go down hole on the fly or tie flowback water back into frac supply for reuse. Based upon the needs of your sand challenge enercorp will combine different cyclone and filtration technologies to meet your needs. Water treatment and recycling has the ability to decrease operator costs while sustaining and expanding water sources and supporting an environmentally.

Our mobile miox frac water unit offers an efficient effective low cost solution for treating high volumes and high rates of flowback water with superior bacterial kill. The flowback phase sand management configuration illustrated here is an example of a potential wellsite layout. Deep well injection open air pits or treatment and reuse of the water. Flowback typically lasts between 30 and 120 days.

Well testing enables making key production measurements such as flow rate fluid properties and composition pressure and temperature at. After a well has been drilled the casing cemented the shale fractured the pad laid and the piping and production equipment installed the flowback phase begins. But in general flowback water is less saline and contains chemicals that are used as part of hydraulic fracturing fluids. And because miox technology operates with salt water and electricity there are virtually no health safety or environmental concerns at the drill site or down hole.

The distinction between flowback water and produced water can be subjective.
