Halliburton Assembles World Class Fiber Optic Capability to Provide Operators with Greater Visibility into Reservoirs

Acquisition of Optiphase Assets Completes Fiber Optic Sensing Puzzle

HOUSTON - July 16, 2013 - Halliburton (NYSE: HAL) has completed acquisition of the assets of Optiphase, Inc., a leading provider of interferometric fiber optic sensing solutions including Distributed Acoustic Sensing (DAS) interrogation systems. (Terms and cost of the acquisition were not disclosed.) DAS technology turns a piece of fiber optic cable similar to what one would use for cable or telephone service into a fully distributed noise logging system. When applied to an oil and gas well, operators can tune in to any section of the fiber and listen to what is happening in their well. Applications are varied and include stimulation and production monitoring, verification of downhole equipment operation, pipeline monitoring and collection of seismic imaging data.

In addition to fiber's ability to transmit data at high rates, the same piece of glass can be turned into a distributed sensing system, or point sensors can be spliced into the line to provide additional capabilities. The naturally high melting point of glass and its immunity to electrical
noise make it ideal for use in harsh, high temperature environments such as deep unconventional wells or wells stimulated with steam to increase oil mobility. Operators are using this new high speed, optical collection of information to more efficiently operate their assets.
"Over the past decade, Halliburton has made significant, strategic investments in the area of fiber optic sensing," said Karl Blanchard, Vice President of Halliburton's Production Enhancement business line. "The company has assembled a world class fiber optic capability, which we are leveraging across the organization to provide our customers with greater visibility into how their reservoirs are producing."
Acquisitions that make up Halliburton's fiber optic capability include the assets of permanent reservoir monitoring leader Pruett Industries some 10 years ago; an equity investment in Prime Photonics, a company that specializes in designing fiber optic sensing for extreme environments; Pinnacle Technologies, which focuses on the use of fiber optics for both high speed wireline telemetry as well as distributed wellbore sensing; SensorTran, the world leader in Distributed Temperature Sensing (DTS) systems; and Davidson Downhole with a focus on pressure sensing in high temperature environments.
"Complementing our fiber optic manufacturing and operations expertise, Halliburton has invested in setting up the Applied Photonic Center in Houston - a research facility devoted to the advancement of fiber optic based sensing technologies," said Dr. Gregory Powers, Vice President of Technology for Halliburton. "With the in-house fiber optic sensor physics capability that we have assembled, we now have the ability to rapidly innovate in this space and leverage the benefits of fiber optics far beyond its use as a data telemetry medium. We are also continuing to work with multiple clients as well as external universities and research institutes to push the envelope of this new sensing technology."
