IHS Inc. (NYSE: IHS) announced Nov. 19 it has acquired Houston-based PacWest Consulting Partners. The value of the transaction wasn't disclosed.

PacWest plays a critical role in helping both buyers and suppliers of hydraulic fracturing services and related products understand the market dynamics of stimulating production from unconventional and conventional reservoirs and making strategic decisions to support their businesses.

Scott Key, president and CEO of IHS, described PacWest as a “strong fit” with the Englewood, Colo.-based company.

PacWest’s “IQ” series of products—PumpingIQ, WellIQ, ProppantIQ and others, he said, are synergistic with current IHS offerings, and expand the presence of IHS in the hydraulic fracturing and related unconventional space.

“By combining the information and analytics of PacWest with our current energy information, insight and expertise, we will strengthen our position in the hydraulic fracturing segment of the unconventionals business in North America and beyond,” Key said in a statement. “This enhanced capability will add value to both existing and potential customers.”

Based in Houston with an office in Beijing, PacWest employs 23 people.

Nilesh Dayal, founder and managing partner of PacWest Consulting Partners, said in a statement, “The combination of our people, capabilities and market intelligence will intensify our strategic insights to our clients and bolster our ability to develop and expand into other critical, underserved areas of the global oilfield services value chain. We are excited about the growth opportunities as part of the IHS family.”
