Electromagnetic Geoservices ASA

What Electromagnetic Geoservices ASA does

Electromagnetic Geoservices ASA (EMGS) is a Norwegian marine geophysical services company, founded in 2002 and headquartered in Oslo with an R&D and engineering base in Trondheim. The company specializes in Controlled Source Electromagnetics (CSEM) and Magnetotelluric (MT) data acquisition, processing, and interpretation to support offshore hydrocarbon exploration. Its technology portfolio includes proprietary Deep Blue broad-band EM sources, 200+ node seabed receiver capacity, 3D Gauss-Newton inversion with VTI/TTI anisotropy support, joint CSEM/MT inversion for sub-salt and sub-basalt imaging, and in-house software (SBLwiz, EMU, Brickville) available via rental or HPC cloud access. With nearly 1,000 completed surveys worldwide, EMGS positions itself as the marine EM market leader and also markets adjacent applications including marine minerals exploration and CO2 storage monitoring.

EMGS generates revenue primarily through enterprise project-based services: multi-month CSEM and MT survey campaigns delivered to international oil and gas operators, complemented by processing and imaging products, interpretation and integration services, multi-client data library licensing, software and HPC cluster rentals, and training programs. The company sells directly through a global sales organization covering Europe, the Americas (Houston), and Asia Pacific (India, Jakarta), engaging IOC and NOC exploration teams on a quote-based pricing model with large individual contract values.

In April 2026, following a period of financial distress, EMGS completed the sale of its entire business operations and assets (hardware, intellectual property, contractual positions, and all employees) to Riggs Holdco AS (originally P-2 Riggs Capital, Inc.) for up to USD 2.5 million. Under new ownership led by Chairman Patrick Lee Riggs, with former CEO Bjørn Petter Lindhom and CFO Anders Eimstad retained in transitional roles, EMGS is relaunching operational activity through a vessel partnership with Sea Shipping AS (Atlantic) and a USD 6 million Norway CSEM campaign, while the listed entity itself has discontinued quarterly reporting and holds a limited cash position relative to total liabilities.

Core offering

EMGS provides marine electromagnetic (EM) survey services to offshore oil and gas companies using proprietary Controlled Source Electromagnetics (CSEM) and Magnetotelluric (MT) technology. The offering spans the full workflow — pre-acquisition studies, survey design, data acquisition using purpose-built EM vessels, processing, 3D inversion, imaging, interpretation, and integration with seismic and well data. The company also licenses a multi-client data library and rents proprietary software (EMU, Brickville, SBLwiz) on its HPC cluster.

Product overview

EMGS offers a unified marine electromagnetic technology portfolio for offshore hydrocarbon exploration. The core offerings include CSEM (Controlled Source Electromagnetics) and MT (Magnetotelluric) data acquisition, processing, and interpretation services. The technology portfolio spans from pre-acquisition sensitivity studies through 3D inversion, joint CSEM & MT inversion, and the EMGS Exploration Solution—a 4-stage integrated workflow combining CSEM experts with interpreters. Supporting the technology are proprietary software tools including SBLwiz (for processing and imaging), EMU, and Brickville (for interpretation), all available via software rental or cloud computing on EMGS's HPC facility. The company also provides training, interpretation services, and operates purpose-built EM vessels with capacity for over 200 nodes.
