Halliburton introduced its CYPHER Seismic-to-Stimulation service at the 2013 SPE ATCE in New Orleans, La. The CYPHER service is a collaborative workflow that effectively integrates geoscience, reservoir, drilling and completion engineering to allow operators to better predict and produce unconventional reserves.
“Understanding the reservoir potential, identifying the most productive pay, designing the well placement and optimizing the most frac and completion are all critical to getting the lowest cost for the highest production from the well and from the assets,” Brady Murphy, senior vice president, global business development and marketing, said at a news conference.
A technology suite using an iterative process that identifies the best well placement and stimulation designs, critical parameters to the total well cost and ultimate production supports the service. Shale and tight reservoirs can contain multiple sweet spots mixed with nonproductive rock, and misplaced fracturing zones or missed production opportunities can result in expensive wells and sub-optimized well economics. Cumulative production can vary widely in a field, depending on well placement. In the Eagle Ford, for example, one operator gained a four-fold increase in cumulative production and reduced drilling costs by increasing the accuracy of wellbore placement using the CYPHER service.
In North Texas, results from a 26 well data set showed a 67% increase in production and 80% reduction in well standard deviation, Stephen Ingram, manager of North America technology and marketing, said. CYPHER is currently in a dozen programs worldwide.
The CYPHER service, built on collaboration, integrates all available data – seismic, cores, logs, microseismic and production – and is supported by advanced applications for earth modeling, formation evaluation, horizontal drilling, complex fracture modeling, reservoir simulation and more. Field trials are under way in the US, Europe and the Asia Pacific region.
CYPHER is a service mark of Halliburton.
