An offshore oil platform.
A well bay provides an access point to a well and accompanying equipment on a drilling rig. On automated rigs, the well bay may make up the majority of the rig, while larger rigs include worker accommodation, processing facilities, and other structures. A rig can feature multiple wells, allowing the oil company to extract resources from multiple wells using the same rig. Like other components used in drilling, the well bay is regularly inspected to confirm that it is in operational order and needs to meet health and safety standards set by regulators involved in oil drilling operations.
This equipment can be used with both dry and wet equipment. For offshore drilling, subsurface drilling equipment is required, while shallower water operations may use dry rigs above the ocean surface. Depending on the type of well, the situation and the company, the well bay can have one or two levels. The lower level provides access to the wellhead, while the upper level allows workers to manipulate controls and hardware on the drill rig’s so-called Christmas tree.
Size determines whether a well bay can accommodate one or more wells. This is built into the design of the platform, based on the results of oil and gas exploration conducted in the area to determine what type of equipment may be needed. Oil companies work with engineers and technicians to develop the most efficient and effective equipment, including not just the platform but also pipelines, terminals and other components needed to transport oil from the ocean to onshore refineries.
Within the well bay, workers can maintain components, operate controls and perform tests. Their work may include specific interventions to resolve problems with the well, as well as emergency shutdown procedures. Wells may need to be closed so workers can evacuate, for example, if critical safety issues arise on the platform. They can also be individually controlled to allow workers to repair them, a process that may require stopping production to clean and replace components in an overhaul.
Workers at the well bay wear proper safety equipment, including hard hats and other equipment that may be required by the production company. They also receive safety training so they know how to work safely on site. Oil rigs can be dangerous, especially during bad weather, and workers need to be coordinated and organized.
