NSTA Wells (WGS84)
收藏资源简介：
<p><span style='color:inherit; font-size:inherit; font-family:var(--fontsBaseFamily),Avenir Next;'>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’: https://whatisawell.ppdm.org/.</span><br /></p><p>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). Visit the BGS website for more information.</p><div><span style='font-family:"Avenir Next", "Avenir Next"; font-size:16px;'>Well Bottom Hole is the bottom hole location of the borehole at its final measured total depth.</span><br /></div><div><font face='Avenir Next, Avenir Next'><span style='font-size:16px;'>Top Hole - Bottom Hole, Straight Line Connection is a straight line connection from the top hole location and bottom hole location, it is not a wellbore path.</span></font></div>
