we are premier Corex

Premier Corex is a global leader in the aggregation, generation, and application of rock and fluid data, utilizing it to better understand, explore, and develop earth resources. We believe the data-driven energy industry is here, and that generating and sharing relevant data from rock and fluid samples is the key to more effective and efficient resource development.

We’ve assembled world-class experts, facilities, and platforms to produce that data, make it readily accessible, and help our clients share it effectively.

We generate, aggregate, interpret, and deliver consistent, high-quality data that are of immediate value to oil and gas companies.


“We are excited to embrace Premier Corex as our new company name globally. We believe the name Premier Corex reflects our commitment to service our clients in a continuously evolving energy industry and our pledge to be leaders in global energy transition and sustainability. We are excited to unify all our employees under this new name while we remain true to our core - Illuminating the Subsurface” Randal Wichuk, CEO.

our history

Premier Corex (formerly known as Premier Oilfield Laboratories) was formed in May 2016 under the private equity sponsorship of CSL Capital Management. Over the next 2 years, the team acquired and integrated six businesses, focused on the generation and interpretation of rock and fluid data.



Laboratory assets of FTSI – significant expertise and lab capabilities related to water chemistry, stimulation fluid systems, proppant evaluation, production enhancement, and flow assurance.


Mud Geochemical Acquisition

MUD Geochemical – early-stage business applying rapid elemental analysis on core and drill cuttings to optimize horizontal well placement and completion design.



COREX Limited – international provider of routine and special core analysis, PVT analysis, and EOR analysis, with centers of excellence in Aberdeen, UK and Cairo, Egypt.


Conocophillips Labs Acquisition

Subsurface R&D assets of ConocoPhillips – deep expertise, lab capabilities, and unique workflows related to unconventional (very low permeability) rock characterization, rock mechanics, imaging of rock fabric, measurement of dynamic rock properties (rock mechanics), and enhanced oil recovery (EOR).


Midland & OKC Labs Formed

Midland & OKC Labs Formed – Established laboratories in Midland, Texas and Oklahoma City, Oklahoma to collect, process, and characterize rock and fluid samples in convenient proximity to highly active areas such as the Permian Basin and SCOOP/STACK.


Midland Sample Library Acquisition

Midland International Sample Library – a unique collection of drill cuttings and core samples from over 200,000 wells, covering all major US basins, which Premier saved from imminent destruction and is now restoring and digitizing as the Premier Sample Library.



During 2018, the company coalesced under a new brand and gained significant market traction.  Recognizing that the data-driven oil and gas industry is here, we have emphasized our commitment to generating and sharing rock and fluid data by reorganizing our capabilities into three areas: Data Generation, Data Aggregation, and Data Analysis & Interpretation.

Premier Corex established its global headquarters in Houston, TX, hosting a full-service laboratory for rock and fluid analysis along with satellite facilities in Denver, and Midland. In addition to the laboratory locations and offices, Premier acquired MUD Geochemical, Inc. of Austin, TX, the ConocoPhillips Subsurface Research Laboratory of Bartlesville, OK, and The International Sample Library of Midland, TX which hosts the largest private collection of rock samples.

Internationally, Premier acquired COREX. Founded in the 1980s, COREX became one of the world’s leading independent core analysis providers before joining Premier in December 2016. Premier inherited - and continues to grow - COREX centers of excellence in Aberdeen (Scotland) and Cairo (Egypt), as well as front-line laboratories in Noida (India), Basra (Iraq), Abu-Dhabi (UAE) and Al Ahmadi (Kuwait). In addition to routine and special core analysis, Premier Corex is known as a pioneer in formation damage assessment, an area of continued global leadership within Premier today.

Premier Corex is proud to build on the reputation of innovation and excellent customer service that its acquisitions have established over 45+ years in business, supporting clients throughout Europe, Africa, the Middle East, Far East, and Australia.

We have established new business models that facilitate cost-effective data generation through cost-sharing approaches, and that help groups of clients to solve common challenges through shared data workspaces. We believe in the preservation and curation of subsurface samples and data, using them to address the challenges of today’s energy industry and tomorrow’s resource opportunities. These new ways of doing business set Premier Corex apart from other testing-focused laboratories.
