Oil and gas services are heavy users of Class 1 explosives — perforating charges that breach well casing into the reservoir, seismic exploration charges, well stimulation explosives, and various Class 3 frack fluids. The industry's logistics center of gravity is the Texas-Gulf corridor, but Ramar's Atlantic Coast network covers the Marcellus shale region (PA / WV) and serves as a drayage origin for imported well-completion materials and energetic equipment.
Halliburton, SLB, Weatherford, and BJ Services move multi-class freight through East Coast ports for distribution to Mid-Atlantic and Northeast operations. Ramar drays from Norfolk, Philadelphia, and Charleston for those lanes and runs OTR to active basin operations as needed. Cove Point LNG export terminal (Maryland) generates occasional logistics relevance.
