Illustration of deep horizontal drillhole disposal concept. Deep horizontal drillhole disposal is the concept of disposing of high-level radioactive waste from a nuclear reactor in deep horizontal boreholes instead of in more traditional deep geological repositories that are excavated like mines.
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 ...
For many years, the world's longest borehole was the Kola Superdeep Borehole in Russia. From 2011 until August 2012 the record was held by the 12,345-metre (40,502 ft) long Sakhalin-I Odoptu OP-11 Well, offshore the Russian island Sakhalin. [11] The Chayvo Z-44 extended-reach well took the title of the world's longest borehole on 27 August 2012 ...
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 ...
The German Continental Deep Drilling Programme (German: Kontinentales Tiefbohrprogramm der Bundesrepublik Deutschland, lit. 'Continental deep-drilling program of the Federal Republic of Germany'), abbreviated as the KTB borehole, was a scientific drilling project carried out from 1987 to 1995 near Windischeschenbach, Bavaria.
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.
Many national regulations stipulate that for any well drilled, a set of samples must be archived with a national body. For example, in the case of the UK with the British Geological Survey . The bulk of the cuttings require disposal. The methodology for disposal is dependent on the type of drilling fluid used. For water based drilling fluid ...
The current record holders manage wells over 10 km (6.2 mi) away from the surface location at a true vertical depth (TVD) of only 1,600–2,600 m (5,200–8,500 ft). [4] This form of drilling can also reduce the environmental cost and scarring of the landscape. Previously, long lengths of landscape had to be removed from the surface.
