UK England onshore petroleum wellbores bottom holes (WGS84)

<p>A wellbore is a path of drilled footage from the Well Origin to a terminating point. The location of each wellbore is the wellbore's well origin. A well origin is the location on the surface of the earth or sea bed where the drill bit penetrates the earth to establish or rework a well. Definitions for wellbore and well origin taken from PPDM ‘what is a well:&nbsp;<a target='_blank' href='https://whatisawell.ppdm.org/' rel='nofollow ugc noopener noreferrer'>https://whatisawell.ppdm.org/</a>’.<br />Data collection starts once a well has been spudded when the operator submits a spud notification on WONS. The NSTA will issue an official well number via WONS, which is to be used for all data and records resulting from the well's drilling.<br />All well data requirements are set out in the documents Petroleum Operations Notices (PON) 9 (offshore) and PON 9b (onshore).<br />Onshore operators have a statutory obligation to also supply well data to the British Geological Survey (BGS).
