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.
The University of Illinois/NCSA Open Source License is a permissive free software license, based on the MIT/X11 license and the 3-clause BSD license. By combining parts of these two licenses, it attempts to be clearer and more concise than either. [3] The license is the result of efforts by a University of Illinois committee set
Open Design Alliance is a nonprofit organization creating software development kits (SDKs) for engineering applications. ODA offers interoperability tools for CAD, BIM, and Mechanical industries including .dwg, .dxf, .dgn, Autodesk Revit, Autodesk Navisworks, and .ifc files and additional tools for visualization, web development, 3D PDF publishing and modeling.
The terms measurement while drilling (MWD), and logging while drilling (LWD) are not used consistently throughout the industry. Although these terms are related, within the context of this section, the term measurement while drilling refers to directional-drilling measurements, e.g. for decision support for the wellbore path, (Inclination and ...
AADE – American Association of Drilling Engineers [1] AAPG – American Association of Petroleum Geologists [2] AAPL – American Association of Professional Landmen; AAODC – American Association of Oilwell Drilling Contractors (obsolete; superseded by IADC) AAV – Annulus access valve; ABAN – Abandonment, (also as AB and ABD and ABND)
Drilling Formula Sheets is a set of Drilling Formulas used commonly by drilling engineers in the onshore and offshore oil drilling industry. They are used as part of a key piece of engineering work called Well Control .
Logging while drilling (LWD) is a technique of conveying well logging tools into the well borehole downhole as part of the bottom hole assembly (BHA).. Although the terms Measurement while drilling (MWD) and LWD are related, within the context of this section, the term MWD refers to directional-drilling measurements, e.g., for decision support for the smooth operation of the drilling, while ...
Drilling engineering is a subset of petroleum engineering. [1] Drilling engineers design and implement procedures to drill wells as safely and economically as possible. [1] They work closely with the drilling contractor, service contractors, and compliance personnel, as well as with geologists and other technical specialists.
