Microseismic tool reveals proppant success rate during fracking

Microseismic Inc., an oilfield services provider of hydraulic fracturing mapping and data, has announced a new analytical tool to measure the effectiveness of proppant placement during the fracking process. The trademarked Productive-SRV system uses three microseismically derived calculations to estimate target zone productivity, the fracture network, the size of fracture and the drainage capability of each fracture, according to the company. The combination of these techniques can be used to estimate 90-day cumulative production, the company also said. 

“Hydraulic fracturing has been effective at stimulating fractures in the subsurface for more than 60 years,” said Michael Thornton, chief technology officer. “However, increasing hydrocarbon recovery requires those fractures to stay open. The overburden pressure of 10,000 feet of rock will quickly close a fracture if it is not wedged open with proppant. Productive-SRV helps our clients quickly determine which completion techniques are most effective by estimating the effects of proppant placement at optimum well spacing.” 

The tool also helps to estimate the volume of fractures that are likely proppant filled, by using data and known treatment parameters in combination with near wellbore geology. By estimating the volume of fractures filled by proppants on a per-stage fracturing basis, the company said, a more constrained area of stimulation is determined which provides a more accurate correlation to early production.
