Oil and Gas Cables

We have extensive experience working with Oil & Gas clients. In fact, we provide custom cable assemblies and wire harnesses that are rugged and withstand the hazardous and harsh environments of the oil fields. Moreover, our in-house overmolding team has produced thousands of custom molds to increase durability and solve the unique problems found on land and sea rigs. Additionally, we offer an extensive selection of durable jacket options (including steel braiding) to protect against abrasion, extreme heat, and other harsh elements.

Furthermore, we have a proven track record of providing connectivity solutions for a wide range of oilfield applications. Specifically, we possess experience in land-based oilfield drilling, well sites, production platforms, offshore drilling, pump rooms, logging systems, measurement-while-drilling, seismic systems, data acquisition, and telemetry, among others. As a result, our solutions are designed to improve operational efficiency and safety, while minimizing downtime and maintenance costs.

MRO operates with IPC/WHMA-A-620D Certified Trainers and Application Specialists, with continuing training for all certified employees to ensure compliance with the latest revisions to the standard. We are an IPC Class 2 and Class 3 EMS Provider.

IPC Class 2: Dedicated Service

Includes products where continued performance and extended life is required, and for which uninterrupted service is desired but not critical. Typically, the end-use environment would not cause failures.

IPC Class 3: High Performance/Harsh Environment

Includes products where continued performance or performance-on-demand is critical, equipment downtime cannot be tolerated, end-use environment may be uncommonly harsh, and the equipment must function when required, such as life support systems and other critical systems.
