Navigator, in partnership with BlackRock Real Assets, closed on its purchase of 100% of GMP in December of 2017. GMP is an approximately 250-mile, multi-play crude oil transportation system located in the STACK/Merge, Granite Wash and Mississippi Lime plays, delivering crude oil to a one million-barrel GMP-owned storage facility at Cushing, Oklahoma.

In support of the significant volume growth within the STACK/Merge and Woodford resources plays, Navigator plans to expand the footprint and overall capacity of the GMP system. Working with producer partners, substantial new gathering infrastructure is also anticipated. The considerable scale of the existing GMP system and its ability to segregate multiple grades of crude allows Navigator to offer customers a fulsome, differentiated suite of services to transport and store crude oil.


Our Commitment to Safety

More than 200,000 miles of pipeline crisscross our country. Generally buried underground, pipelines are the safest and most efficient way to move natural gas, crude oil, chemicals and related products. Pipelines reduce air and water pollution by eliminating the need for trucks and ships on our roads and waterways.

Our pipeline spans more than 250 miles in 10 counties here in Oklahoma. One or more of our pipelines may be located on or near your property. As a pipeline operator, and your neighbor, we are committed to safely operating our pipelines. Awareness and understanding of pipelines will enhance your personal safety as well as that of others.

It is important to know where pipelines are located in your community and how to recognize unusual conditions and the signs of a possible leak:

  • An unusual pool of liquid along the pipeline right of way (ROW)
  • An unusual fog or vapor mist along the pipeline ROW
  • Dead or discolored vegetation that is usually green along the ROW
  • Unnatural frost or ice in the pipeline ROW or on well location equipment
  • An unusual hissing or roaring noise coming from the pipeline ROW
  • An unusual chemical odor such as gas or oil along the pipeline ROW
  • A strange odor in the area similar to the smell of rotten eggs

Trust your senses. If you see, hear or smell any of the above signs, take action right away:

  • Leave the area immediately. Travel into the wind and away from the hazardous fumes or liquid.
  • Do not touch, breathe or make contact with leaking liquids or fumes.
  • Do not light a match, start an engine, use a telephone (even a cell phone), switch on/off light switches or do anything that may create a spark.
  • Do not drive into a leak or vapor cloud area.
  • Call 911 or your local emergency response number from a safe location. Give your name, phone number, description of the leak and its location.
  • Warn others to stay away.

Know what's below. Call 811 before you dig.

Excavation is the single largest cause of damage to the nation's pipeline system, accounting for nearly 40 percent of all accidental spills. You can help maintain the integrity of the pipeline system and prevent accidents by using the nationwide Call Before You Dig service by calling 811, which acts as a clearinghouse to inform the owners and operators of underground facilities so that they can mark their facilities, usually within two business days.

If you plan to dig or do any type of excavation or construction work, federal and state law may require you to call your local state One-Call Center. A Navigator representative will locate and mark the underground pipeline at no cost to you. The local One-Call center can be found here
