GeoExpro Magazine article "A Brave New World of Hybrid Recording"
Bob Heath puts the case for hybrid recording - the use of two or more seismic instruments together. This is not limited to cabled with cableless, it covers virtually any combination of equipment to show how maximum flexibility, minimised HSE exposure and cost are the result (Oct, 2013).

With so many cableless systems to choose from, it appears sometimes the market may be confused as to the differences between each technology. Bob Heath sheds light on this issue and discusses some of the most important factors to examine when considering cableless acquisition (May, 2012).

DEW Magazine article "Cableless seismic in difficult environments"
iSeis's International Marketing Manager starts by providing a short history of seismic instrumentation to show how hardware flexibility radically affects how we can undertake seismic surveys. In this extensive particle, the basic physics or 2.4 GHz-based radio communication is also covered, as well as the results of company testing and comparison of various comms technologies. Now end-users can be sure of what really is possible in cableless recorders (Nov, 2013).

First Break

For the 2012 EAGE Convention issue of First Break, we describe how various types of equipment permit (or restrict) different geophysical surveys to be undertaken, both passive and active. This inevitably leads to hardware which can be configured to allow the highest efficiency, safety and data quality in any operation (June, 2012).

The Leading Edge

SEG's November 2009 issue of The Leading Edge features an article by iSeis technical marketing manager, Bob Heath. The article revisits Ian Jack's grounbreaking paper "System 2000" to note the advancements in cableless seismic. Bob also explains how seismic exploration will be cheaper, safer and more environmentally friendly if it is done without cables.

Fourth OilVoice Forum

The fourth OilVoice Forum was held in London on June 24th, 2009 with the theme of Tough Problems in Geophysics. The aim was to tackle issues such as tough terrains (tundra, transition zone, deep ocean bottom) and tough "requests" (Why can't land 3D be as fast and as cheap as marine? Can't we drastically reduce the time it takes to acquire and process?).

Bob Heath of i-Seis descirbes how new developments in cableless land acquisition help to solve these geophysical problems.
