Velseis Pty Ltd is an Australian seismic exploration company providing a fully integrated range of seismic technologies. Velseis has built a reputation as the leading Australian contractor in this field, with over 25 years of experience throughout the Asia-Pacific Region. The company provides contracting services for coal, mineral and hydrocarbon exploration utilising Dynamite, Mini-SOSIE, Vibroseis and Airgun sources.

Services available include survey design, drilling, data acquisition (3D, 2D, and multicomponent), data processing and interpretation. Velseis prides itself on its ability to configure a specialised acquisition service to suit any situation. The company can provide conventional 3D and 2D crews, as well as portable, helicopter and shallow-marine recording.

Over the last decade, Velseis has been at the forefront in development of high-resolution 3D seismic imagery. This technology has been driven by the needs of the coal-mining industry, but is also stimulating interest from the minerals and environmental sectors. Recently a shallow-marine seismic vessel, The Velseis Explorer, was commissioned. The company also has ongoing contracts in the petroleum seismic arena.
