Wellsite Information Transfer Specification
The Wellsite Information Transfer Specification (WITS) is a specification for the transfer of drilling rig-related data. This petroleum industry standard is recognized by a number of companies internationally and is supported by many hardware devices and software applications.{{Citation needed, date=November 2021 WITS is a multi-layered specification: * Layer 0 describes an ASCII-based transfer specification * Layer 1 describes a binary-based format based on 25 predefined fixed-size records and the Log Information Standard (LIS) data-transmission specification * Layer 2 describes bidirectional communication using LIS Comment records * Layer 2b describes buffering of data * Layer 4 extends the previous layers to use a different data exchange formatRP66 Though still in active use as of 2013, the specification has been superseded by the XML-baseWITSML See also * Wellsite information transfer standard markup language Drilling technology Petroleum technology ...

Drilling Rig
A drilling rig is an integrated system that Drilling, drills wells, such as oil or water wells, or holes for piling and other construction purposes, into the earth's subsurface. Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and such are called auger (drill), augers. Drilling rigs can sample subsurface mineral deposits, test rock, soil and groundwater physical properties, and also can be used to install sub-surface fabrications, such as underground utilities, instrumentation, tunnels or wells. Drilling rigs can be mobile equipment mounted on trucks, tracks or trailers, or more permanent land or marine-based structures (such as oil platforms, commonly called 'offshore oil rigs' even if they don't contain a drilling rig). The term "rig" therefore generally refers to the complex equipment that is used to penetrate the surface of the Earth's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petroleum Industry
The petroleum industry, also known as the oil industry or the oil patch, includes the global processes of hydrocarbon exploration, exploration, extraction of petroleum, extraction, oil refinery, refining, Petroleum transport, transportation (often by oil tankers and pipeline transport, pipelines), and marketing of list of crude oil products, petroleum products. The largest volume products of the industry are fuel oil and gasoline (petrol). Petroleum is also the raw material for many petrochemical, chemical products, including pharmaceutical drug, pharmaceuticals, solvents, fertilizers, pesticides, synthetic Aroma compound, fragrances, and plastics. The industry is usually divided into three major components: upstream (petroleum industry), upstream, midstream, and downstream (petroleum industry), downstream. Upstream regards exploration and extraction of Petroleum, crude oil, midstream encompasses transportation and Oil terminal, storage of crude, and downstream concerns refining ...

Computer Hardware
Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), random access memory (RAM), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard. By contrast, software is the set of instructions that can be stored and run by hardware. Hardware is so-termed because it is " hard" or rigid with respect to changes, whereas software is "soft" because it is easy to change. Hardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware. Von Neumann architecture The template for all modern computers is the Von Neumann architecture, detailed in a 1945 paper by Hungarian mathematician John von Neumann. This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of an arithmet ...

Software
Software is a set of computer programs and associated software documentation, documentation and data (computing), data. This is in contrast to Computer hardware, hardware, from which the system is built and which actually performs the work. At the low level language, lowest programming level, executable code consists of Machine code, machine language instructions supported by an individual Microprocessor, processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of Binary number, binary values signifying Instruction set architecture, processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction System call, may also invoke one of many Input/output, input or output operations, for example displaying some text on ...

Wellsite Information Transfer Standard Markup Language
{{Short description, Web development language WITSML is a standard for transmitting technical data between organisations in the petroleum industry. It continues to be developed by an Energistics facilitated Special Interest Group to develop XML standards for drilling, completions, and interventions data exchange. Organizations for which WITSML is targeted include energy companies, service companies, drilling contractors, application vendors and regulatory agencies. A modern drilling rig or offshore platform uses a diverse array of specialist contractors, each of whom need to communicate data to the oil company operating the rig, and to each other. Historically this was done with serial transfer of ASCII data. Purpose The drilling, completions, and interventions functions of the upstream oil and natural gas industry need universally available standards to facilitate the free flow of technical data across networks between oil companies, service companies, drilling contractors, ap ...

Drilling Technology
Drilling is a cutting process where a drill bit is spun to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multi-point. The bit is pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute. This forces the cutting edge against the work-piece, cutting off chips (swarf) from the hole as it is drilled. In rock drilling, the hole is usually not made through a circular cutting motion, though the bit is usually rotated. Instead, the hole is usually made by hammering a drill bit into the hole with quickly repeated short movements. The hammering action can be performed from outside the hole ( top-hammer drill) or within the hole ( down-the-hole drill, DTH). Drills used for horizontal drilling are called drifter drills. In rare cases, specially-shaped bits are used to cut holes of non-circular cross-section; a square cross-section is possible. Process Drilled holes are ...
