Extra notes: This has to do with finding anyone that has something to do with managing, operating, purchasing, specifying, maintaining equipment for land seismic surveying. Surveying being the sub specialty of surveying used within the seismic exploration business.

So I would think that first we need to find any company that claims they offer land seismic data acquisition services, or that offer surveying services to the land seismic companies. Land seismic could be defined by many terms – here are the most common:
seismic exploration onshore
land seismic exploration
Onshore 2D and 3D data acquisition (2D and 3D are types of seismic data acquisition)
Geophysical data acquisition onshore/land
land seismic acquisition
Onshore seismic data acquisition
Etc.

Here is a classic web site that lists many of these companies
http://www.oilfieldworkers.com/directory.php?page_category=seismic-land

Once we have found the companies that these individuals may work for or within we then need to focus on the “surveying” components of these companies. These companies will have many people that are responsible for other things than surveying – I am only really interested in the senior management and the individuals involved in surveying or positioning within the seismic company.

The problem is that the word “Survey” is used to describe the seismic data acquisition process as well as the “surveying” needed to precisely position the components of a seismic job (surveyors are used to do this). We sell an inertial backpack that surveyors would use to stake out or position a land seismic job.

If you look at http://www.extremesurveys.com/ they use the word survey and surveying correctly – they provide surveying services to the seismic acquisition industry. “Providing GPS, Inertial Surveying Services, in Desert, Mountain, Canopy and Arctic Environments”

If you look at http://oilandgasuk.co.uk/knowledgecentre/seismicsurveys.cfm they use the word “survey” to describe the overall process of collecting seismic data.

I want to just find the people (like the ones at Extreme above) that are responsible for the surveying or positioning for seismic data acquisition.

Some other terms that may help:

GPSeismic – the software used by just about all land surveyors that are involved in land seismic surveying http://www.gpseismic.com/index.html
Vibroseis, Vibe, Sweep, Upsweep, Downsweep, - these are the large trucks that send the energy into the earth to collect seismic data – so positioning a vibe truck is a surveying activity
TigerNav, TigerNav Lite – some of the software used by land seismic surveyors
Source, receiver, line – a surveyor will be surveying in a source point or a receiver point on a survey line


What I want is a CSV or Excel file of anyone who has something to do with surveying for the land/onshore seismic community.

What I would like would be:

First Name, Last Name, Company name, Job title/description, Email, Country,

If available – but not as important would be Phone number, location address

If I cannot get an email – we will then have to source emails for others in the company and construct and email in the form of the company email format.

Here is a good example of a LinkedIn profile for someone that I would be looking for: Les Merriam - Geodetic & GIS Services Supervisor at ION Geophysical

I have two lists (one with url's) of seismic exploration companies that I have uploaded.
