Wellhead Clause Samples
The Wellhead clause defines the rights, responsibilities, and specifications related to the installation, operation, and maintenance of the wellhead equipment at an oil or gas extraction site. Typically, this clause outlines which party is responsible for providing, installing, and maintaining the wellhead, as well as the standards and procedures that must be followed to ensure safety and regulatory compliance. For example, it may specify that the operator must use equipment that meets certain industry standards and is subject to inspection. The core function of this clause is to allocate responsibility for the wellhead, ensuring operational safety and regulatory adherence while clarifying obligations between parties.
Wellhead. The place where Petroleum, Natural Gas, liquefied petroleum gas and other Hydrocarbons resulting from the exploitation in the Field are measured, after they have been suited for transport.
Wellhead. Wellhead with sufficient pressure rating is selected from the maximum design pressure and temperature. In conventional ▇▇▇▇▇, the maximum design pressure is assumed to be from a well filled with saturated steam from the bottom of the well to the top, where the bottom hole pressure and temperature conditions is assumed to follow the boiling point depth curve (BPD). For a superheated well, it can be assumed that the well is filled with isenthalpic superheated steam from the bottom, with assumption that from the critical point, the bottom hole pressure increases with depth according to a fixed gradient or other assumption mentioned before. From the IDDP-1 experience, it is clear that the pressure difference between bottom hole and the wellhead is governed by the weight of the steam column in the well and frictional pressure drop is negligible (▇▇▇▇▇▇▇, et al., 2015). The wellhead conditions of RN-15/IDDP-2 of temperatures >345°C to <500°C and pressures of 155 to 250 bar are likely, judging from several thermal gradient estimates (▇▇▇.▇▇▇▇.▇▇). The wellhead master valves from IDDP-1, pressure rating of ASME Class 1500 valve with Class 2500 flanges and material type 1.9 (▇▇▇▇▇▇▇, et al., 2010), were improved and refabricated and used for RN-15/IDDP-2 (▇▇▇▇▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇, 2017).
Wellhead. Top of a casing and the attached control and flow valves. The well head is where the control valves, testing equipment and take-off piping are located. Flowing of well fluids to provide information on how hydrocarbon will flow from the reservoir, well productivity and the reservoir properties.
