General information
General information Attribute Value Wellbore name Official name of wellbore based on Norwegian Offshore Directorate guidelines for designation of wells and wellbores.7230/5-U-5Type Wellbore type. Legal values: EXPLORATION, DEVELOPMENT, OTHER (see 'Purpose' for more information)OTHERPurpose Final classification of the wellbore.
Legal values for exploration wellbores:
WILDCAT, APPRAISAL, WILDCAT-CCS, APPRAISAL-CCS.
Legal values for development wellbores:
OBSERVATION, PRODUCTION, INJECTION, INJECTION-CCS, OBSERVATION-CCS.
Legal values for other wellbores:
SOIL DRILLING (drilling in connection with track surveys and other subsurface surveys to investigate the soil conditions prior to placement of facilities),
SHALLOW GAS (drilling to investigate shallow gas before the first 'real' drilling on the location),
PILOT (drilling to investigate the geology and fluid connectors for location of the main wellbore),
SCIENTIFIC (drilling according to Law of Scientific research and exploration),
STRATIGRAPHIC (driling according to Law of Petroleum activities §2-1).SCIENTIFICStatus Status for the wellbore. Legal values are:
BLOWOUT: A blowout has occurred in the well.
CLOSED: A development wellbore that has been closed in a shorter or longer periode. Also applies to development wellbores where drilling is completed, but production/injection has not yet been reported.
DRILLING: The well is in the drilling phase – can be active drilling, logging, testing or plugging,
JUNKED: The drilling operation has been terminated due to technical problems.
P&A: Exploration: The well is plugged and abandoned, and can not be reentered for further use. Development wells: The production/injection from/to the well is stopped and the well is plugged. The wellhead is removed or else made unavailable for further well operations.
PLUGGED: The wellbore has been plugged, but the upper parts of the wellbore can be re-used. A sidetrack might be drilled at a later stage.
PRODUCING: It was produced from the wellbore at the time of the operators last monthly report to the Norwegian Offshore Directorate.
INJECTING: It was injected to the wellbore at the time of the operators last monthly report to the Norwegian Offshore Directorate.
PREDRILLED: The upper part of the well has been drilled, usually as part of a top-hole drilling campaign covering several wellbores.
RE-CLASS TO DEV: Exploration wellbore that is reclassified to a development wellbore and given a new name.
RE-CLASS TO TEST: Exploration wellbore that is reclassified to test production and given a new name.
SUSPENDED: The drilling operation in the wellbore has been temporarily stopped. The current plan is to continue drilling later on.
WILL NEVER BE DRILLED: Wellbore registered with a name and WellID by the Norwegian Offshore Directorate, but which for various reasons will not be drilled.
ONLINE/OPERATIONAL: The wellbore is ongoing, but not completed, may be operations such as drilling, batch-drilling, logging, testing, plugging, preparation for production/injection or temporarily stopped in connection with the operations.
P&AMultilateral Indicator telling if the parent well is multilateral, meaning it has more than one branch radiating from the main borehole. Example of legal values: YES, NO. See also Norwegian Offshore Directorate guidelines for designation of wells and wellbores.NOFactmaps in new windowMain area Name of the area on the Norwegian Continental Shelf where the wellbore is located. Legal values: BARENTS SEA, NORWEGIAN SEA, NORTH SEA.BARENTS SEAWell name Official name of the parent well for the wellbore based on Norwegian Offshore Directorate guidelines for designation of wells and wellbores.7230/5-U-5Prod. licence for drilling target The active production licence of the planned drilling target of the wellbore. This can differ from the production licence the wellbore was drilled from.Drilling operator Name of the licensee starting the drilling operation on behalf of the active production licence. This is usually the operator of the production licence.IKU Petroleumsforskning SINTEF GruppenDrill permit The drilling permit number together with the version of the drilling permit as stated in the drilling permit granted by the Norwegian Offshore Directorate.91-GEntered date The date when he wellbore was spudded. For sidetracks: The date when new formation was drilled by kicking off from the mother-wellbore.22.07.1987Completed date Exploration wellbores from moveable facilities:
For floating facilities – date when anchor handling is started. For jackups – date the jacking-down started.
Exploration wellbores from fixed facilities and all development wellbores:
Date when the wellbore is at total depth, and last casing, liner or screen is set. In case of immediate plugging of the wellbore, completed date equals the date the last plug i set in the wellbore.09.09.1987Release date Date when raw data which has been reported to the authorities from the wellbore is not confidential any longer. Normally 2 years after finishing the drilling. May be earlier if the area of the production licence is relinquished.09.09.1989Discovery wellbore Indicator which tells if the wellbore made a new discovery. Legal values: YES, NO. Prior to press-release or other information regarding drilling results, the indicator will be “NO” as a default.NOKelly bushing elevation [m] Elevation of the rotary kelly bushing (RKB) above mean sea level.2.9Water depth [m] Depth in metres betweem mean sea level and sea floor.286.0Total depth (MD) [m RKB] Total measured length of wellbore from kelly bushing to total depth (driller's depth).335.0Oldest penetrated age Age (according to Geologic Time Scale 2004 by F. M. Gradstein, et al. (2004)) of the oldest penetrated formation. May differ from age at TD for example in deviated wellbores. Examples of legal values: CRETACEOUS, EARLY CRETACEOUS, LATE JURASSIC, EARLY PERMIAN, EARLY TRIASSIC, EOCENE.MIDDLE TRIASSICGeodetic datum Reference system for coordinates. Example of legal values: ED50.ED50NS degrees Geographic coordinate of the wellhead, north-south degrees.72° 42' 6'' NEW degrees Geographic coordinate of the wellhead, east-west degrees.30° 22' 31.64'' ENS UTM [m] Universal Transverse Mercator coordinate of the wellhead, north-south.8070572.18EW UTM [m] Universal Transverse Mercator coordinate of the wellhead, east-west.611979.53UTM zone Universal Transverse Mercator zone.
