Our History

Driven By Success

In 1994, Probe was established in Fort Worth, Texas by a group of ex-Gearhart engineers as a technology company specializing in the design of downhole logging tools initially targeted at the North American market. As our patented Radii™ gained market acclaim, it positioned Probe as the industry's leading independent supplier and expert in cement bond and acoustic logging technology.

Engineering excellence, innovation and customer focus run deep throughout Probe. In our efforts to remain aligned with our customers’ needs, we typically reinvest most of our profits in developing new products and sustaining engineering. Our purpose is to offer an ever-expanding range of inteligent solutions. We achieve this by developing new products, and by continuously improving existing products, with the most reliable technology.

In 2008, Probe sought external growth capital investment to further support our commitment to expand our core cased hole logging business into complementary product lines and to enable international market entry. 

With fresh capital investment, Probe expanded rapidly. In 2009, California-based Kuster was first to join the Probe Group, followed just one year later in 2010 by Sensor Developments in Norway and Sentergy in the UK. AKS Technologies, a Denver, Colorado company that specialized in surface wireless solutions, joined the ranks in 2011. Soon thereafter, SP-1 in Aberdeen, Scotland came on board in 2012 and later followed by Isle Oil Tools in 2014. In December of 2017, Probe announced the newest addition to the business through the strategic merger with Hunter Well Science in Canada.

Over Probe's history of organic and inorganic growth, the Company has steadily developed in-region support capabilities to better assist our international customer base. We established Geo Centers for Latin America (Villahermosa, Mexico in 2009), Europe and West Africa (Aberdeen, Scotland in 2010), and Middle East, North Africa and Asia (Dubai, UAE in 2012).  
Since 2008, Probe has continued to expand its Fort Worth and Aberdeen Technical Center footprint, launched an Engineering Support Center in Houston (2015), and invested in two new test wells in the Fort Worth Technical Center.  Engineering spend more than doubled over this period, and remains comparatively constant, even during industry downturns. The latest addition of Hunter continues to expand Probe's in-region support and Engineering capabilities with its Canadian facilities (Calgary, Alberta in 2017).

Our company has achieved outstanding organic and in-organic growth, consolidating a wealth of engineering expertise which has transformed Probe into the company that it is today: the industry’s leading cased hole technology experts.
