Well services is a department within a petroleum production company through which matters concerning existing wells are handled. Having a shared well services department for all (or at least multiple) assets operated by a company is seen as advantageous as it allows the pooling of talent, experience and resources for managing wells.
An oil well is a boring in the Earth that is designed to bring petroleum oil hydrocarbons to the surface. Usually some natural gas is released along with the oil. A well that is designed to produce only gas may be termed a gas well.
The term may sometimes be used to encompass the larger section of the industry responsible for wells including the supplier companies as well the operating company's wells department.
A well is initially drilled and completed under the control of the drilling and completions department operating under the request of the asset. Once the well is completed, control is transferred to the asset's production team, who will operate the well as appropriate for their purposes. Should any issues of well integrity or any requirement for well work arise, the asset will refer the issue to the well services. During interventions, control of affected well is handed over from production to the well services crew at the well site, a practical action involving transferring control lines from the production control panel to the well services control panel.
When well work is required, it is the responsibility of the WOE to assemble the team and arrange their dispatch to the well site. The team will consist of a well services supervisor and other operators. The well services supervisor is a dedicated worker who is sent to oversee well services operations at well sites and take responsibility for all well services personnel. At offshore sites, there will commonly be two, to cover both day shift and night shift. The other operators will usually consist of personnel from supplier companies, who are trained in the relevant field, such as wireline, coiled tubing, wellhead maintenance, etc.
In the oil and gas industry, the term wireline usually refers to a cabling technology used by operators of oil and gas wells to lower equipment or measurement devices into the well for the purposes of well intervention, reservoir evaluation, and pipe recovery.
In the oil and gas industries, coiled tubing refers to a very long metal pipe, normally 1 to 3.25 in in diameter which is supplied spooled on a large reel. It is used for interventions in oil and gas wells and sometimes as production tubing in depleted gas wells. Coiled tubing is often used to carry out operations similar to wirelining. The main benefits over wireline are the ability to pump chemicals through the coil and the ability to push it into the hole rather than relying on gravity. Pumping can be fairly self-contained, almost a closed system, since the tube is continuous instead of jointed pipe. For offshore operations, the 'footprint' for a coiled tubing operation is generally larger than a wireline spread, which can limit the number of installations where coiled tubing can be performed and make the operation more costly. A coiled tubing operation is normally performed through the drilling derrick on the oil platform, which is used to support the surface equipment, although on platforms with no drilling facilities a self-supporting tower can be used instead. For coiled tubing operations on sub-sea wells a mobile offshore drilling unit (MODU) e.g. semi-submersible, drillship etc. has to be utilized to support all the surface equipment and personnel, whereas wireline can be carried out from a smaller and cheaper intervention vessel. Onshore, they can be run using smaller service rigs, and for light operations a mobile self-contained coiled tubing rig can be used.
A wellhead is the component at the surface of an oil or gas well that provides the structural and pressure-containing interface for the drilling and production equipment.
A well intervention, or well work, is any operation carried out on an oil or gas well during, or at the end of, its productive life that alters the state of the well or well geometry, provides well diagnostics, or manages the production of the well.
A film crew is a group of people, hired by a production company, for the purpose of producing a film or motion picture. The crew is distinguished from the cast as the cast are understood to be the actors who appear in front of the camera or provide voices for characters in the film. The crew is also separate from the producers as the producers are the ones who own a portion of either the film company or the film's intellectual property rights. A film crew is divided into different departments, each of which specializes in a specific aspect of the production. Film crew positions have evolved over the years, spurred by technological change, but many traditional jobs date from the early 20th century and are common across jurisdictions and film-making cultures.
An oil platform, offshore platform, or offshore drilling rig is a large structure with facilities for well drilling to explore, extract, store, and process petroleum and natural gas which lies in rock formations beneath the seabed. In many cases, the platform contains facilities to house the workforce as well.
A distributed control system (DCS) is a computerised control system for a process or plant usually with a large number of control loops, in which autonomous controllers are distributed throughout the system, but there is central operator supervisory control. This is in contrast to systems that use centralized controllers; either discrete controllers located at a central control room or within a central computer. The DCS concept increases reliability and reduces installation costs by localising control functions near the process plant, with remote monitoring and supervision.
Professional diving is diving where the divers are paid for their work. There are several branches of professional diving, the best known of which is probably commercial diving and its specialised applications, offshore diving, inshore civil engineering diving, marine salvage diving, HAZMAT diving, and ships husbandry diving. There are also applications in scientific research, Marine archaeology, fishing and aquaculture, public service and law enforcement and military service. Any person wishing to become a professional diver normally requires specific training that satisfies any regulatory agencies which have regional or national authority, such as US Occupational Safety and Health Administration, United Kingdom Health and Safety Executive or South African Department of Labour. Due to the dangerous nature of some professional diving operations, specialized equipment such as an on-site hyperbaric chamber and diver-to-surface communication system is often required by law.
Filmmaking is the process of making a film, generally in the sense of films intended for extensive theatrical exhibition. Filmmaking involves a number of discrete stages including an initial story, idea, or commission, through screenwriting, casting, shooting, sound recording and reproduction, editing, and screening the finished product before an audience that may result in a film release and exhibition. Filmmaking takes place in many places around the world in a range of economic, social, and political contexts, and using a variety of technologies and cinematic techniques. Typically, it involves a large number of people, and can take from a few months to several years to complete.
A diving support vessel is a ship that is used as a floating base for professional diving projects.
Dispatchers are communications personnel responsible for receiving and transmitting pure and reliable messages, tracking vehicles and equipment, and recording other important information. A number of organizations, including police and fire departments, emergency medical services, motorcycle couriers, taxicab providers, trucking companies, railroads, and public utility companies, use dispatchers to relay information and coordinate their operations. Essentially, the dispatcher is the "conductor" of the force, and is responsible for the direction of all units within it.
The Armed Forces of Malta is the name given to the combined armed services of Malta. The AFM is a brigade sized organisation consisting of a headquarters and three separate battalions, with minimal air and naval forces. Since Malta is the guardian of the European Union's most southerly border, the AFM has an active role in border control.

Critical infrastructure protection (CIP) is a concept that relates to the preparedness and response to serious incidents that involve the critical infrastructure of a region or nation.
A theatrical technician, is a person who operates technical equipment and systems in the performing arts and entertainment industry. In contrast to performers, this broad category contains all "unseen" theatrical personnel who practice stagecraft and are responsible for the logistic and production-related aspects of a performance including designers, operators, and supervisors. Many professional designers and technicians consider the diminutive "techie" to be offensive.
The Royal Australian Army Ordnance Corps (RAAOC) is the Corps within the Australian Army concerned with supply and administration, as well as the demolition and disposal of explosives and salvage of battle-damaged equipment. The Corps contains clerks, operator supplies, petroleum operators, parachute riggers and ammunition technicians. Members of the Corps are nicknamed Roaches.
ISO/IEC 27002 is an information security standard published by the International Organization for Standardization (ISO) and by the International Electrotechnical Commission (IEC), titled Information technology – Security techniques – Code of practice for information security controls.
In the Petroleum industry, Integrated operations (IO) refers to the integration of people, disciplines, organizations, work processes and information and communication technology to make smarter decisions. In short, IO is collaboration with focus on production.
Staff management is the management of subordinates in an organization. Often, large organizations have many of these functions performed by a specialist department, such as personnel or human resources, but all line managers are still required to supervise and administer the activities, and ensure the well-being, of the staff that report to them.

A diving team is a group of people who conduct a diving operation. A characteristic of professional diving is the specification for minimum personnel for the diving support team. This typically specifies the minimum number of support team members and their appointed responsibilities in the team based on the circumstances and mode of diving, and the minimum qualifications for specified members of the diving support team. The minimum team requirements may be specified by regulation or code of practice. Specific appointments within a dive team for which competences are specified and registration may be required are listed below.
