Terēan™

You can do this.

Rapidly and cost-effectively determine subsurface ground conditions for geotechnics, engineering, mining, energy, and research.

Geotechnics

Reliably and quickly determine critical subsurface information for less cost; such as earthquake ground shaking potential per the International Building Code (IBC), depth and velocity of subsurface layers, and rheologic properties of earth & rock.
Engineering

Confidently and independently evaluate the depth, lateral extent, and rheologic properties of subsurface soil and rock layers. Constrain the location of faults and slides and determine the effectiveness of compaction and earth remediation projects.
Mining

Save cost by covering your mineral resource ground reliably and rapidly to understand depth to bedrock, locate faults, estimate excavation and hauling costs, constrain the location of ore & waste rock zones, and monitor earthen structures; such as tailings retention dams.
Energy

Non-invasively image basin-wide earth structure to over 10,000 feet (3,200 m) depth, to assist in developing drill targets for producing energy resources in commercial quantities.
Research

State-of-the-art seismic data processing software for research, teaching, and collaboration on a local or planetary exploration scale.

"The results from the last job I did turned out great – the Vs100 came within 3 ft/s of seismic CPT down to 100 feet."

Quick and Easy to Use

VsSurf™ ReMi™ software gives every user the ability to get geologic and geophysical subsurface information for geotechnics, engineering, and geotechnical engineering applications - autogenerate a report with an accurate and ASCE 7-22 compliant seismic site classification in less than 30 minutes. The analysis is conceptually simple - you can train your field crews and leave the field knowing you have a result that is accepted by building authorities around the world.

"I've personally used ReMi since 2005 on hundreds of sites at this point, and is my go-to method for shear wave velocity to 100'+ (usually 300'+) even above DHS, CHS, SCPT and refraction surveys. I've used the method on small retail sites to industrial sites to deep TBM tunnels to levees to power/nuclear sites...with and without surface coverings (such as pavements)...many of which were blind surveys. The method provides invaluable data in seismic site class determination and especially SSSA w/ SRA per ASCE7. Many thanks for your white papers and expert support thru the decades!"

Methods accepted in both industry and academia

ReMi™ software enables small and large institutions to give their students the practical training that the industry demands while facilitating research projects. VsSurf analyses are backed by dozens of peer-reviewed publications.

“Let me start by saying that the VsSurf software is very user-friendly! Secondly, the training and support that comes with VsSurf is unmatched! Alison [Lead Geophysicist & Operations Manager - Terēan] is definitely focused on making sure that the client is familiar and knowledgeable with both the software, and the field equipment used to obtain the data. The expertise of the Terēan Team is simply amazing!”
