Recent giant pre-salt discoveries offshore Brazil have made the Santos basin one of the
most active areas for oil and gas exploration. Until recently, most of the basin has been …

摘要海底节点(OBN) 在有效弥补拖缆地震(TS) 的勘探盲区, 提供多波和宽方位角数据,
定点和重复性等方面具有优势, 成为海洋地震勘探的新技术方法. 近十年来, OBN …

During ocean bottom seismic acquisition, seafloor multicomponent geophones located in
rugose and sloping water bottom can be affected by skewed energy distribution, such as …

ABSTRACT A common problem in deepwater node surveys is the lack of accurate
information on the depths of nodes deployed at the seafloor. Tides, rapidly changing water …

Multicomponent seismic exploration offers advantages in precisely describing complicated
geological structures compared with conventional PP-wave exploration. For multicomponent …

In 2019, the fourth ocean-bottom-node survey was acquired over Atlantis Field. This survey
was quickly processed to provide useful time-lapse (4D) observations two months after the …

In deepwater OBN, uncertainties in sensor positions lead to errors in the static solutions and
deteriorate imaging capabilities. In particular, node depths are generally measured with an …

Ocean bottom node (OBN) systems are common exploration methods for deep water
seismic observation. However, seismic detection nodes in existing OBN systems were …

A system and method for estimating clock drift in underwater instruments is provided. The
method can include transmitting a signal from a source to a plurality of underwater receivers …

In seismic processing, especially for deep water Ocean Bottom Nodes (OBN), precise
location data of shots and receivers is crucial. Uncertainties in sensor positions can cause …
