All wells and wellbores drilled on the Norwegian shelf are assigned a number, and often also a popular name.
Before commencing drilling, the operator must submit a form to us for name assignment and classification.
Our guidelines for how wells and wellbores on the Norwegian shelf are to be designated relate to all types of wells. The official designations are based on the block and quadrant in which the well is drilled (for example 34/8-13 A). Popular names are also used on occasion (for example Titan).
The operator must fill out a form for naming and classification of all wellbores. The form must be sent to us no later than two weeks prior to start-up of drilling.
The Resource Management Regulations define an exploration well as a well that is drilled to prove potential petroleum deposits, or to obtain information needed to delineate a proven deposit.
We grant permission for exploration drilling, and assigns the proper designation to the wellbore. Such a permit must be granted for the respective well or wellbore before drilling activity is initiated.
The permit is granted on the basis of registration applications and drilling programs, and on the condition that all other permits and consents required by other authorities have been secured.
Exploration wells are divided in two categories: wildcat wells and appraisal wells.
Under the Resource Management Regulations, this is a common designation for wells used to produce petroleum.
We assign wellbore designations based on forms submitted by the operator. Development wells are divided into the categories production, injection and observation wells.
Shallow boreholes are defined in Section 2 of the Resource Management Regulations: Holes drilled in order to acquire information on the properties of the rock and/or to conduct geotechnical surveys to determine the location of facilities, and which are not drilled to prove or delimit a petroleum deposit or to produce or inject petroleum, water or other medium.
In reality, the definition includes two types of boreholes that are regulated by different provisions:
On our FactPages you can obtain information about the location of all exploration and development wells. A legend shows the various types of wellbores.
