What affects virtually every stage of the exploration & production lifecycle? Surveying, positioning and spatial data management activities.
Our key work areas
Think the Earth is round? Think again. Actually the Earth - land and sea - is continuously changing shape, influenced by factors such as its rotation, gravity and tectonic movement. Our Practical Geodesy work supports the description of the definitions of coordinates for describing locations on, above and below the surface of the Earth.
In order to improve our industry’s surveying capability, IOGP develops and maintains specialist tools and resources.
The EPSG Geodetic Parameter Dataset is a collection of definitions of coordinate reference systems and coordinate transformations. These may be global, regional, national or local in application. To learn more visit www.epsg.org.
Several IOGP’s short documents give guidance to the industry on geodetic topics:
Information about Guidance Notes on other Geomatics topics may be found on other pages of this web site.
Geo-information (which includes location, coordinate and geo-code) accounts for about 80% of exploration and production data. Much of this information is stored in a variety of applications, databases and formats, including the widely used Geographical Information Systems (GIS).
Common geography provides an extremely powerful means to integrate E&P information in support of business decision-making for exploration, new business, construction, field development and decommissioning - in fact every aspect of the upstream life-cycle. We develop industry guidelines, good practices and specifications regarding the use of this data.
Since its publication in April 2011, the Seabed Survey Data Model (SSDM) Version 1 has become the de facto industry standard for delivering seabed survey data in geographic information system (GIS) format.
Oil and gas companies aim to manage seabed survey data based on sound geo-information management principles and practices.
Historically, geographical features interpreted from seabed survey have been delivered in unstructured CAD files that have led to many difficulties in the management of survey data. These issues include the fact that data from different surveys has been difficult to integrate and share with joint venture partners. In view of these needs, the IOGP Seabed Survey Data Model (SSDM) Task Force was formed in 2010 to define a standard GIS data model for seabed survey. This model can be used as a deliverable standard between Oil and gas companies and survey contractors, as well as a sound data model for managing seabed survey data at an enterprise level within oil and gas companies.
Version 1 of the SSDM package may be downloaded here. The zip will unpack itself into the following structure:
The SSDM v1 was launched at the ESRI Petroleum User Group in April 2011. The launch presentation may be downloaded here.
Seabed Survey Data Model (SSDM) update presented at the OGP Geomatics Industry Day, October 2012, Kuala Lumpur, available here.
In March 2013 IOGP Report No. 462-02, Guideline for the delivery of the SSDM was published. The purpose of the document is to provide a technical specification for the delivery of seabed survey data in GIS format and in compliance with the IOGP SSDM.
The IOGP P6/11 seismic bin grid data exchange format defines the following parameters for a 3D seismic survey:
Since the creation of the original P6 format in 1998, Geographic Information System (GIS) has become a common application used by operators to manage, analyse and map geo-information. GIS enables integration of geo-information of which seismic positioning data is an essential component. The requirement to be able to visualize and use seismic bin grid definitions and data in GIS has become increasingly important for:
With this in mind, IOGP has developed a GIS data model for the storage and visualization of seismic bin grid definitions that is based on the new IOGP P6/11 seismic bin grid exchange format.
The P6 GIS Data Model package may be downloaded here. The zip will unpack itself into the following structure:
Crisis response teams tackling the 2011 Japanese Tsunami disaster and the 2010 Haiti earthquake were helped by access to information generated by a space technology known as ‘Earth Observation’. This view from space can also help the oil and gas industry - and not only in a crisis.
Also known as ‘remote sensing’, it involves using earth-orbiting satellites or dedicated survey aircraft to obtain timely access to information about the status of the surface of the Earth.
The advantages of this technology – both onshore and offshore – include:
Other applications could include:
The OGEO Portal, supported by the Earth Observation Subcommittee, creates a platform designed to allow an improved communication between the service providers and the oil and gas companies. To find out more go to http://www.ogeo-portal.eu.
The IOGP’s Geophysical Operations Subcommittee monitors and identifies the need for industry guidelines or standards for exploration, development and production related geophysical operations, with the objective of recommending good industry practice to improve the safety, quality and efficiency, and to develop new guidelines and standards as required. Specific areas of interest include:
We promote continuous improvement in the quality of geophysical data used to assess drilling or development risk due to shallow / seabed hazards and also in seismic positioning, in support of increasingly demanding geophysical objectives and the developments in acquisition techniques necessary to achieve them.
We maintain the following IOGP Geomatics Committee guidelines and data exchange standards through regular reviews and document updates in accordance with the IOGP requirements, either in direct control or through temporary Task Force(s):
Guidelines for the conduct of offshore drilling hazard site surveys
P1/11 Geophysical position data exchange format
P1/11 Geophysical position data exchange format - User Guide
P2/11 Positioning data exchange format
P6/11 Seismic bin grid data exchange format
P6/11 Guidelines for the use of the OGP P6/11 bin grid GIS data model (see here for the P6 DM)
We are also the custodians of several legacy positioning formats:
Data Exchange Format - Post Plot
Data Exchange Format - Raw Marine Positioning Data
Data Exchange Format – 3D Seismic Binning Grids
EPSG Co-ordinate Reference System Description in UKOOA P Formats
P1, P2, P3, P4 Standard exchange formats for positional data
We liaise and cooperate with other IOGP subcommittees, task forces, industry groups and other stakeholders on matters of mutual concern.
More information regarding new P1/P2 is available here and on new P6 – here
Please send any P formats feedback to [email protected].
We monitor and identify the need for industry guidelines or standards for survey and positioning operations and recommend good industry practice to improve the quality, safety and efficiency of these operations and to develop new guidelines and standards as required.
We also maintain the following IOGP Geomatics Committee guidelines and data exchange standards through regular reviews and document updates in accordance with the IOGP requirements, either in direct control or through temporary Task Force(s):
The purpose of this Guidance is to provide geoscience software developers and users with recommended industry best practice to evaluate the capabilities of their software with respect to establishing and maintaining geospatial data integrity.
GIGS is a process developed in response to significant concern and user experiences of violations of geospatial integrity of data when using geoscience software, resulting in incorrect results, inconsistent understanding and misleading information for the user community.
The Guidance comprises six items, downloadable below:
‘Part 1 – Guidelines’ IOGP report number 430-1, describing the GIGS process. This guidance note is supplemented by a companion MS PowerPoint slide pack (with notes) explaining the GIGS process and business benefits
‘Part 2 – Software Review’ IOGP report number 430-2, containing a software review checklist to enable structured testing of geoscience software.
This software review document is supplemented by an MS-Excel spreadsheet version (ZIP or RAR) of the checklist, intended to facilitate the execution of a geoscience software review and capture its results
‘Part 3 – User guide for the GIGS Test Dataset’ IOGP report number 430-3. This user guide supports a series of data files to be used for testing of the algorithms and data exchange capabilities of the geoscience software. The test dataset may be downloaded here (ZIP or RAR).
