Year: 2023 First Published: IMAGE Authors: Tiexing Wang*, Arash JafarGandomi, Hakon Aune Summary Harmonics in vibrator technology are a common phenomenon and often viewed as undesirable noise. Their presence is widely discussed and treated in the context of land vibrators, with much emphasis dedicated to their removal. However, the discussion on marine vibrator harmonics remains […]

Year: 2023 First Published: IMAGE Authors: Tiexing Wang, Arash JafarGandomi, Hakon Aune Summary In vibrator technology, the presence of harmonics is a common phenomenon. Several authors considered the problem of removing or utilizing harmonics from land vibrator data. However, marine vibrator (MV) harmonics are rarely discussed. Although much weaker than the fundamental signal, we show […]

Year: 2023 First Published: EAGE Authors: R H Telling, A JafarGandomi, R M Laws, S Grion Summary This paper examines a method of signature estimation for marine vibrators that jointly uses measurements of the acceleration of the vibrating surfaces and the pressure in the near-field to invert for notional sources. The method enables an optimal […]

Year: 2023 Authors: Jing Sun, Arash JafarGandomi, Julian Holden Summary In ocean bottom seismic (OBS), combining records from the hydrophone (P-component) and vertical geophone (Z-component) allows for the elimination of receiver-side ghost and water-layer multiples. Apart from environmental noise that affects both of them, the Z-component is often contaminated by an additional type of shear-like […]

Year: 2023 First Published: EAGE Authors: C Strand, J Canning, D Eastwell, C Rudling, K Purcell, R Bartlett Summary It is internationally recognised that the safest method for permanent disposal of higher-activity radioactive waste is in a deep, underground Geological Disposal Facility (GDF). The UK has, along with several countries, embarked on a project to […]
