Global Oilfield Services Leader

Global Oilfield Services Leader Minimizes Risks/Costs by Proactively Maintaining Inventory of Electronic Components

One of the world’s largest oilfield services providers reduced uncertainty about parts obsolescence and replacement availability by providing its employees with real-time access to data for 25,000+ parts and eliminating delays to part change notices. The company also ensured compliance with latest REACH, RoHS and Export regulations.

  • Reduce uncertainty when manufacturers are going to end of life a computer component
  • Minimize risks and costs from changes to parts by taking precautions to ensure supply of spares
  • Determine if they want to leverage updated components in new computer designs


IHS Technology with IHS PCNalert and IHS BOM Manager


  • Provided real time access to detailed data and documents on 25,000+ parts
  • Eliminated previous delays to EOL and PCN notices for computer components
  • Achieved cost savings by proactively managing component part obsolescence issues
  • Received EOL notifications regarding 800+ components which resulted in last-time buys for 500 of those components
  • Advised design engineers on part discontinuance, predicted component lifecycle and part alternatives
  • Ensured compliance with the latest REACH, RoHS and Export component regulations

Oil Services Leader Maintains Electronic Parts Inventory

One of the world’s largest oilfield services providers is renowned for its ability to deliver a full range of innovative technical solutions and capabilities – including seismic surveys, formation evaluation, drilling technologies and equipment, cementing, well construction and completion, and project management. For decades, this company has supported oil industry leaders with a broad array of reservoir evaluation, development, and management services, and it continues to develop new technologies for reservoir optimization.

To support its global operations, the company custom builds computers that are inserted into drill pipes and lowered two to three miles underground. The computers monitor the environment underground and provide critical information back to the company operators. The company designed these computers with more stringent requirements than could be tolerated by standard commercial computers due to the high pressure, high heat and high vibrations in the underground environment. Despite the taxing environment that the computers are subjected to, some of these computers are expected to be out in the field for 20 years. Therefore, when it finds computer components that are able to withstand this harsh environment, the company is very reluctant to make any component changes. The majority of these products are custom made for insertion into the drill holes. Hundreds of products are tested. Testing takes six months to two years to certify that a specific component can continue to perform properly under such difficult conditions. The company also utilizes a number of surface computers - however the primary concern for obsolescence is for the computers that are in the drill holes.

Parts obsolescence is a significant burden for custom equipment that is two to three miles underground. It is critical that the company understands when a manufacturer is going to end of life (EOL) one of its computer components in the custom computers. Changes related to component parts - known as product change notices (PCNs) – are vital issues for the company and the ramifications must be completely understood so precautions can be taken to ensure the company has sufficient spares or can determine if it wants to leverage the updated components in a new computer design.

Today, this oilfield services leader uses IHS PCNalert to monitor an inventory of more than 25,000 parts. Its employees can actively track product change notices issued by more than 1,000 component suppliers and match their AVL parts to identify obsolescence, compliance, end-of-life and counterfeit risks.

Proactively Managing to Reduce Risks/Costs

This oilfield services company uses IHS PCNalert to monitor the Approved Vendor List (AVL) or bill of materials (BOMs) for its electronic equipment. The company leverages contract manufacturers (CMs) to build much of the equipment. In the past, it relied on the CMs to monitor component EOLs but it found that the CMs did not advise the company in a timely fashion on new EOL and PCN notices. This delay caused the company to work in a reactive environment and increased the expense of managing component part obsolescence.

Today, this oilfield services leader uses IHS PCNalert to monitor an inventory of more than 25,000 parts. Its employees can actively track product change notices issued by more than 1,000 component suppliers and match their AVL parts to identify obsolescence, compliance, end-of-life and counterfeit risks. With these timely updates, the company is able to make a last-time buy decision and purchase sufficient quantities of the EOL component prior to the date the component is no longer produced by the component manufacturer.

To date, this company has seen more than 800 of its components reach their EOL. Yet it has been able to proactively manage and mitigate the potential risks to its customers’ operations by making the necessary advance purchases and holding inventory on more than 500 of these EOL components.

Designing for Performance and Compliance

Engineers at the company are also effectively leveraging another tool, the IHS BOM Manager, for new product designs by loading in a bill of material (BOM) for a new computer design. During this design and testing phase, it is critical for the design engineers to understand if any of the parts are going to be discontinued or if the predicted life cycle of a component has changed. In addition, the company’s engineers can utilize the parts alternative capability within IHS BOM Manager.

Finally, this global oil services leader makes effective use of IHS solutions to ensure compliance with key industry standards and government regulations. For example, since its computer equipment is widely deployed across Europe and other countries that are subject to Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) and Restriction of Hazardous Substances Directive (RoHS) regulations, the company leverages the regulation details in IHS BOM Manager to ensure it stays in compliance with the latest REACH and RoHS component regulations updates. The company also needs to ensure that they do not ship any ITAR restricted components overseas so they rely on IHS Export Compliance details for assistance.

In all of these ways and more, this well-known oilfield services company is working with IHS solutions to achieve its business goals for today and tomorrow.
