At the Upper Palatinate location, however, it was hoped to reach the Erbendorfkörper – a deep-lying mass that is believed to be on the boundary of a former continental plate and is identified by its characteristic reflection of seismic waves. Even though the Erbendorfkörper was not reached, the KTB drilling was widely considered a success ...
This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality. Notice that 'free and open-source' requires that the source code is available and users are given a free software license.
A drilling rig is used to create a borehole or well (also called a wellbore) in the earth's sub-surface, for example in order to extract natural resources such as gas or oil. During such drilling, data is acquired from the drilling rig sensors for a range of purposes such as: decision-support to monitor and manage the smooth operation of ...
The borehole can also change to an oval shape while drilling, which typically occurs in doglegs where the axis of borehole is bending to change the direction of the well. This oval shape can cause a 2-arm caliper log to overestimate the size of the borehole, if its arms get stuck in the long-axis.
It is the most common method of reference for locations in the well, and therefore, in oil industry speech, "depth" also refers to the location itself. Strictly, depth is a vertical coordinate related to elevation, albeit in the opposite direction. However, "depth" in a well is not necessarily measured vertically or along a straight line.
In today's puzzle, there are seven theme words to find (including the spangram). Hint: The first one can be found in the top-half of the board. Here are the first two letters for each word: WA. WA ...
A series of consecutive surveys are needed to track the progress and location of a wellbore. Prior experience with rotary drilling had established several principles for the configuration of drilling equipment down hole ("bottom hole assembly" or "BHA") that would be prone to "drilling crooked hole" (i.e., initial accidental deviations from the ...
