Oct 2, 2017 · The advantages of full azimuth, long offset illumination, characteristic of ocean bottom node (OBN) acquisition, are shown in data examples from deep-water pre-salt fields in the Gulf of Mexico.

Abstract: Ocean bottom seismometers have been used by academia for several decades to study mostly the deep subsurface. But only since recently, such ocean bottom nodes (OBN) have been used in commercial seismic surveys for oil & gas exploration and development.

In this paper we describe how a new and novel application of node technology has been combined with a well established physical phenomena to support the acquisition of a world first exploration-scale Ocean Bottom Node (OBN) survey.

OBC and OBN seismic exploration are all laid “geophones” on the seafloor to collect seismic data. A complete OBC and OBN field acquisition operation includes three main processes: cable laying, cable positioning and seismic data acquisition.

In the summer of 2013, a field test was conducted in the Gulf of Mexico to acquire seismic data during an ocean-bottom node (OBN) survey using unmanned water vehicles, or wave gliders, towing a...

We present a joint tomography flow for ocean bottom node (OBN) and streamer wide azimuth data in deep water Gulf of Mexico. This tomography method uses surface offset gathers from surveys with different shot and receiver datums together for joint tomography.

Nov 1, 2023 · At the time of writing, the world’s largest OBN survey is continuing in the Middle East and is starting to deliver a promising dataset from the 23,000 MEMS-based OBNs deployed. Observations from this mega-survey, as well as from a previous experimental survey that includes direct comparisons with geophone-based OBN, are presented and ...

In recent years, two predominant acquisition trends have emerged: multi-source dense streamer acquisition, ideal for shallow targets requiring high-resolution imaging, and ocean bottom node (OBN) acquisition, initially designed for complex sub-salt imaging.

Dec 14, 2023 · A hybrid towed streamer and ocean bottom node (OBN) survey was acquired in the summer of 2020 over the Quad 35 block offshore Norway in ∼400m water depths. The nodes were located on a 900m × 900m square grid with infills to a 300m × 300m square grid over the Aurora and Nova fields (Figure 1.)
