Study of Hydraulic Fracturing Real-time Evaluation Technology
Study of Hydraulic Fracturing Real-time Evaluation Technology

To a large extent, the effect of hydraulic ,fracturing, depends on the understanding of formation and fracture. And ,hydraulic fracturing real-time evaluation technology, is an important way to understand formation and fracture, adjust construction parameters timely, and then improve ,fracturing, effect. Hydraulic fracture initiation and extension are ...

Handling Produced Water From Hydraulic Fracturing
Handling Produced Water From Hydraulic Fracturing

Halliburton’s mobile CleanWave water service treats produced and ,flowback, water to standards suitable for reuse in ,fracturing, or drilling fluids. Using an electrical process, contaminated water is passed through the system’s electrocoagulation cells where the anodic process releases positively charged ions, which bind onto the negatively charged colloidal particles suspended in water.

Volatile organic constituents have been shown to be present in ,fracturing fluid flowback, wastes at levels that exceed drinking water standards. For example, testing of ,flowback, samples from Texas have revealed concentrations of 1,2-Dichloroethane at 1,580 ppb, which is more than 316 times EPA’s Maximum Contaminant Level for 1,2-Dichloroethane in drinking water .

The wastewater is generally classified in two categories: (1) ,flowback fluid,, which is the ,fracturing fluid, (the mix of water, sand, and chemicals) that returns to the surface when production starts, and (2) production brine (also called produced water, formation water, or simply “brine”), which is the naturally occurring salty water that lies underground and is brought up in the fracking process.

The chemical engineering objectives of a ,fracturing fluid, fall into three categories: Initiate and propagate a hydraulic fracture; Convey a propping agent into the fracture; and; Ensure the proppant pack and formation connect efficiently to the wellbore with minimal damage. Most optimization has historically concerned the first two points.

Therefore, the process of injecting ,fracturing fluid, into the target formation as part of oil or gas production is exempt from these requirements unless the ,fluid, contains diesel. While fracking fluids are exempt under SWDA, wastewater from oil and gas operations, ,flowback, and produced water, are not exempt if disposed of in deep injection wells.

Polymers in the ,flowback fluid, can be in different states of solution and have significantly different molecular weights from the polymers that were pumped downhole. In many cases, a breaking agent is used to reduce polymer viscosity, which promotes HF ,fluid, flow from the fracture and helps the proppant stay in place during ,flowback,.
