Ron Radford

Ron Radford
Principal Partner

Ron Radford manages global operations at ISCT Group US LLC (ISCT™) and all strategic alliances globally. Ron is responsible for managing mercury management and chemical decontamination programs in the US and overseas. Ron has over 20 years of environmental remediation, consulting, and industrial services experience providing specialized services to the energy sector. Ron is based in Thailand and the US Texas Gulf Coast and is responsible for managing projects/programs including remedial construction, facility decontamination, regulatory compliance programs, chemical cleaning, toxic metals sampling and analysis, technology evaluations, and remediation technology development. Since 2005 members of Ron’s group and the R&D team at ISCT™ have been researching the sorption dynamics of mercury in carbon and stainless steel hydrocarbon process systems and developing chemistry and methods to remove mercury from subsea pipelines and topside processing equipment for continued use and in preparation for decommissioning.

Dr. Dennis O’Rear
Technical Research Director

Dr. Dennis O’Rear (formerly Chevron) joined ISCT™ as Technical Research Director and is responsible for providing technical leadership for ISCTs projects globally. Dr. O’Rear is an internationally recognized authority on mercury, and has over 40 years of experience in the petroleum industry in Hydrocarbon processing, GTL, Production Chemistry and Production Geochemistry. Dr. O’Rear is the author of over 120 U.S. patents (13 dealing with heavy metals), has published 13 technical papers, and has acted as an expert witness in 15 European patent oppositions. His mercury patents and expertise span the value chain of petroleum processing from downhole reservoirs, pipelines, gas and crude/condensate facilities, refineries, waste water, solid wastes, and decommissioning of equipment. This work includes an improved understanding of how mercury accumulates on steal and other metals, and the chemistry of how it can be removed during decommissioning. This knowledge improves the effectiveness and reliability of decommissioning, and approaches to managing the mercury waste from this processes.

Derek Peterson

Derek Peterson
Chemical Engineer

Derek Peterson is ISCTs Chemical Engineer and manages all global operations and business development. Mr. Peterson has a Chemical Engineering degree from McNeese State University and started his career as a refinery Process Engineer. After spending several years learning and troubleshooting crude refining processes, Mr. Peterson moved into the chemical and industrial services sector. Mr. Peterson is recognized as a leader in the Industrial Services and Chemical Cleaning sectors of hydrocarbon processing and plant maintenance and decontamination and has spent the last eighteen (18) years of his career focused on building, optimizing and advancing decommissioning, decontamination, chemical and waste treatment procedures and methods for many global upstream, midstream and downstream clients. Mr. Peterson and his team of experts and professionals have systematically redefined and established new standards for the Chemical and Industrial Services industry. He leads a team of experts in the field of chemical cleaning and industrial chemical formulation development providing ISCT™ clients in the midstream and downstream processing sector best of class chemical cleaning services.

Gerard Van der Jagt

Gerard Van der Jagt
Chief Chemist

Gerard Van der Jagt is an internationally recognized mercury analytical chemist, and has 15 years of experience in trace metals analysis, and research programs. He has been involved since 2010 with our research and development team and provided onsite chemical performance and verification analysis on several key projects including recent advanced chemical decontamination and chemical performance/verification analysis for confidential clients in the Americas and Australasia. As chief chemist at ISCT™ Gerard is responsible for key research and development projects to support our process stream sampling and analysis business and also assist with innovation and technology development associated with our mercury, arsenic and NORM chemical decontamination and processing technologies. Gerard has advanced chemical performance measurements of mercury and hydrocarbon removal chemistries such that hydrocarbon and mercury uptake graphs along with trending provide defensible data for contact time and mass removal.

Joseph Nicolette

Joseph Nicolette
Senior Principal, EPS

Joseph Nicolette has over 30 years of experience in the environmental consulting field with a focus on the Oil & Gas Industry. He is a Managing Partner and Ecosystem Services Practice Leader at Environmental Planning Specialists, Inc. (EPS). Joseph is recognized for his demonstrated contributions in developing the net environmental benefit analysis (NEBA) approach, which supports environmental decision-making strategies that provide the greatest net benefit to the public while managing site risks and costs. He co-authored the first formalized NEBA framework recognized by the USEPA, the USEPA Science Advisory Board, NOAA, and AMSA. Joe has led the development of NEBA applications for offshore decommissioning including projects in the Gulf of Mexico, Australia, the North Sea, and the Gulf of Thailand. As applied in these case studies, NEBA focused at evaluating the environmental risks, benefits and costs of component equipment, jackets, pipelines, and FPSO structures so as to balance the risks, benefits, and tradeoffs between various removal, partial removal, and leave in-situ, alternatives, including rigs-to-reefs.

Ian Bonner

Ian Bonner
Chemical Cleaning Specialist

Ian Bonner, international project manager for ISCT™, is responsible for running decontamination projects across the world. Ian has 17 years of experience in the hydrocarbon processing industry with a focus on downstream and offshore chemical cleaning along with subsequent spent chemistries/fluids processing (reduction technologies). Based in Houston and responsible for the day to day running of large decontamination projects, chemical cleaning, toxic metals sampling and analysis and new technology development. Since 2014 Ian has been a key member of the ISCT R&D team and involved in the development of innovative chemical application technologies (vapor phase, circulation, robotic, RHO, chemical gel trains and more)for the chemical decontamination of high value equipment for re-use plus decontamination of equipment scheduled for decommissioning. Ian will take lead in the US for sales and technical support of ISCTs hydrocarbon degassing and metals removal chemistries.

Charles Overstreet

Charles C. Overstreet, P.E.
Chief Engineer

As an SME, Charles Overstreet, is a University of Texas Mechanical Engineer with over 25 years of oilfield experience in the pressure control and offshore sector. His vast knowledge in Snubbing (HWO), Well Control, Coiled Tubing, and structural designs for land, offshore, and subsea applications helped him become a Lead Project Engineer. In that key capacity, he provided engineering support for various service lines ranging from job modeling, internal engineering research to supervisor engineer for complex projects. He performed an early research project for determining pressure-life cycles on high pressure coiled tubing. With his technical experience, Mr. Overstreet has registered six (6) US Patents including two primary inventor patents that are directly related to Snubbing and Sub-Sea applications. He is an active member of the Society of Petroleum Engineers (SPE) and has served as a member of API 16C – WIWC subcommittee and director of ICoTA. Charles is a “think outside the box” problem solver with a no problem is to complex attitude – if we can conceptually design a solution, Charles can build it.
