Big Bang 750

Overview

The Big Bang 750 is an accelerated weight drop seismic source designed for reliable, high-speed, low-cost seismic surveying. Built for high-production mobile acquisition, the system provides fast cycle time and best-in-class move-up time to help reduce field costs and improve production.

The Big Bang 750 provides a full spectrum of useful high and low frequency seismic energy. It includes a handheld controller with 30 feet of wire so the operator can run the system from within the tow vehicle.

The system uses a reliable Honda GX390 four-stroke gasoline power plant with electric start and oil alert. Energy is stored in eight common garage door springs, which are low cost and reliable. With onboard brakes and street legal lights, the Big Bang 750 can move safely down the highway at lane speed.

Benefits

Generate Higher Impact Energy
  • The 750 lb hammer and approximately 20,000 joules of impact energy provide a powerful source for demanding near-surface seismic acquisition.
Increase Field Production
  • The fast cycle time and quick move-up workflow help crews acquire more shots per day.
Reduce Operating Cost
  • Common garage door springs and a reliable Honda power plant help keep maintenance and operating costs low.
Operate From Tow Vehicle
  • The handheld controller and 30 ft cable allow the operator to control the source from inside the tow vehicle.
Move Safely Between Sites
  • Onboard brakes, street legal lights, tires, and trailer coupler support safe highway transport between acquisition areas.
Support Streamer Workflows
  • The rear streamer array storage area supports efficient mobile seismic acquisition using streamer-style receiver systems.
Reduce Field Downtime
  • The electric-start Honda engine and simple spring energy system help support reliable daily field operation.
