Petroleum and natural gas industries - Specific requirements for offshore structures - Part 10: Marine geophysical investigations (ISO 19901-10:2021)
This document provides requirements and guidelines for marine geophysical investigations. It is applicable to operators/end users, contractors and public and regulatory authorities concerned with marine site investigations for offshore structures for petroleum and natural gas industries.
This document provides requirements, specifications, and guidance for:
a) objectives, planning, and quality management;
b) positioning;
c) seafloor mapping, including instrumentation and acquisition parameters, acquisition methods, and deliverables;
d) sub-seafloor mapping, including seismic instrumentation and acquisition parameters, and non-seismic-reflection methods;
e) reporting;
f) data integration, interpretation, and investigation of geohazards.
This document is applicable to investigation of the seafloor and the sub-seafloor, from shallow coastal waters to water depths of 3 000 m and more. It provides guidance for the integration of the results from marine soil investigations and marine geophysical investigations with other relevant datasets.
NOTE 1 The depth of interest for sub-seafloor mapping depends on the objectives of the investigation. For offshore construction, the depths of investigation are typically in the range 1 m below seafloor to 200 m below seafloor. Some methods for sub-seafloor mapping can also achieve much greater investigation depths, for example for assessing geohazards for hydrocarbon well drilling.
There is a fundamental difference between seafloor mapping and sub-seafloor mapping: seafloor signal resolution can be specified, while sub-seafloor signal resolution and penetration cannot. This document therefore contains requirements for the use of certain techniques for certain types of seafloor mapping and sub-seafloor mapping (similarly, requirements are given for certain aspects of data processing). If other techniques can be shown to obtain the same information, with the same or better resolution and accuracy, then those techniques may be used.
Mapping of pre-drilling well-site geohazards beneath the seafloor is part of the scope of this document.
NOTE 2 This implies depths of investigation that are typically 200 m below the first pressure-containment casing string or 1 000 m below the seafloor, whichever is greatest. Mapping of pre-drilling well-site geohazards is therefore the deepest type of investigation covered by this document.
In this document, positioning information relates only to the positioning of survey platforms, sources and receivers. The processes used to determine positions of seafloor and sub-seafloor data points are not covered in this document.
Guidance only is given in this document for the use of marine shear waves (A.8.3.3), marine surface waves (A.8.3.4), electrical resistivity imaging (A.8.3.5) and electromagnetic imaging (A.8.3.6).

Industrija nafte in zemeljskega plina - Posebne zahteve za konstrukcije na morju - 10. del: Morske geofizikalne preiskave (ISO 19901-10:2021)
Ta dokument določa zahteve in smernice za morske geofizikalne preiskave. Uporablja se za upravljavce/končne uporabnike, pogodbenike ter javne in regulativne organe, ki izvajajo morske geofizikalne preiskave za konstrukcije na morju v industriji za predelavo nafte in zemeljskega plina.
Ta dokument določa zahteve, specifikacije in smernice za:
a) cilje, načrtovanje in vodenje kakovosti;
b) določanje položaja;
c) kartiranje morskega dna, vključno s parametri za instrumentacijo in pridobivanje, metodami za pridobivanje in rezultati;
d) kartiranje območja pod morskim dnom, vključno s parametri za seizmično instrumentacijo in pridobivanje ter metodami za neseizmično refleksijo;
e) poročanje;
f) vključevanje in razlago podatkov ter preiskave geoloških nevarnosti.
Ta dokument se uporablja za preiskave morskega dna in območja pod morskim dnom, od obalnih plitvin do globin voda 3000 m in več. Zagotavlja smernice za vključitev rezultatov iz preiskav morskega dna in morskih geofizikalnih preiskav z drugimi ustreznimi nabori podatkov.
OPOMBA 1: Globina, pri kateri se izvaja kartiranje območja pod morskim dnom, je odvisna od ciljev preiskave. Pri konstrukcijah na morju se preiskave običajno izvajajo na globini od 1 do 200 m pod morskim dnom. Z nekaterimi metodami za kartiranje območja pod morskim dnom je mogoče preiskave izvajati tudi veliko globlje (npr. za ocenjevanje geoloških nevarnosti pri izvrtinah ogljikovodikov).
Kartiranje morskega dna in kartiranje območja pod morskim dnom se bistveno razlikujeta: ločljivost signalov na morskem dnu je mogoče določiti, medtem ko to ne velja za ločljivost signalov v območju pod morskim dnom in njihov prodor. Ta dokument zato vsebuje zahteve za uporabo določenih tehnik za določene vrste kartiranja morskega dna in kartiranja območja pod morskim dnom (podobno so podane tudi zahteve za določene vidike obdelave podatkov). Če je mogoče za druge tehnike dokazati, da podajajo enake informacije – z enako ali boljšo ločljivostjo in točnostjo – se lahko uporabljajo te tehnike. Kartiranje geoloških nevarnosti pod morskim dnom na območjih izvrtin pred vrtanjem je del področja uporabe tega dokumenta.
OPOMBA 2: To pomeni izvajanje preiskav na globinah, ki so običajno 200 m pod prvim cevnim stebrom za zadrževanje tlaka ali 1000 m pod morskim dnom (odvisno od tega, kaj je globlje). Zato je kartiranje geoloških nevarnosti pod morskim dnom na območjih izvrtin pred vrtanjem najgloblja vrsta preiskav, zajetih v tem dokumentu.
V tem dokumentu se informacije o določanju položaja navezujejo le na določitev položaja raziskovalnih ploščadi, virov in sprejemnikov. Postopki za določanje položajev podatkovnih točk na morskem dnu in v območju pod morskim dnom v tem dokumentu niso zajeti.
V tem dokumentu so podane zgolj smernice za uporabo morskih strižnih valov, morskih površinskih valov, meritev električne upornosti in elektromagnetnega slikanja.
