A new method was developed and in-house validated to determined ethoxyquin (EQ), butylated hydroxyanisole (BHA) and propyl gallate (PG) in fish silage and fish oil used for production of animal feed. Sample pre-treatment comprises use of QuEChERS (qu

The combination of a vertical dipole source and vertical dipole receiver has several advantages for measurements of subsurface resistivity in a marine environment. To fully exploit the capabilities of this methodology the receiver system needs to mee

Several different CSEM technologies are currently commercially available for offshore exploration, with different characteristics and advantages. Few direct and realistic comparisons between the different methodologies have been made. In this paper w

Vertical-vertical CSEM is an electromagnetic offshore technology that uses specialized sea floor receivers for accurate measurement of the vertical electrical field generated by a vertical transmitter dipole in the sea column. We present four case st

The acronym CSEM has widely become synonymous for frequency domain Controlled Source ElectroMagnetics with seabed nodes and horizontal towed dipole transmitters. While this incarnation of marine CSEM is certainly the best known CSEM variant, it is no

The uncertainty associated with measuring the vertical electric field in marine CSEM for different receiver types was investigated. Different designs for measuring the electrical field subsea have been published by a variety of authors. Our study foc

The EM code of Newman and Commer can be used for inversion of the time domain vertical dipole data of Petromarker. A depth gradient weight function has been calibrated to obtain the original target depth in the inversion. The main goal of the 3D inve
