Drilling wood generally uses higher spindle speeds than metal, and the speed is not as critical. However, larger diameter drill bits do require slower speeds to avoid burning. Cutting feeds and speeds, and the spindle speeds that are derived from them, are the ideal cutting conditions for a tool. If the conditions are less than ideal then ...
Integrated asset modelling (IAM) is the generic term used in the oil industry for computer modelling of both the subsurface and the surface elements of a field development. . Historically the reservoir has always been modelled separately from the surface network and the facilit
As technology has advanced, more modern drillers have better control of the overall well. Oil well control is the management of the dangerous effects caused by the unexpected release of formation fluid, such as natural gas and/or crude oil, upon surface equipment of oil or gas drilling rigs and escaping into the atmosphere.
MODU – mobile offshore drilling unit (either of jack-up drill rig or semi-submersible rig or drill ship) MOF – marine offloading facility; MOPO – matrix of permitted operations; MOPU – mobile offshore production unit (to describe jack-up production rig, or semi-submersible production rig, or floating production, or storage ship)
Well completion is the process of making a well ready for production (or injection) after drilling operations. This principally involves preparing the bottom of the hole to the required specifications, running in the production tubing and its associated down hole tools as well as perforating and stimulating as required.
Spud date: When drilling a new well, the spud date is the day on which the main drill bit begins drilling. For onshore drilling, spudding-in occurs after a wellsite has been prepared and a larger surface hole drilled and cased in preparation for the main drill bit to be used. Subsalt: Refers to oil prospects that lie below a salt layer. [7]
Well drilling is the process of drilling a hole in the ground for the extraction of a natural resource such as ground water, brine, natural gas, or petroleum, for the injection of a fluid from surface to a subsurface reservoir or for subsurface formations evaluation or monitoring.
Surface to down hole communication is typically done via changes to drilling parameters, i.e., change of the rotation speed of the drill string or change of the mud flow rate. Making changes to the drilling parameters in order to send information can require interruption of the drilling process, which is unfavorable due to the fact that it ...
