Pressure control apparatus

A method of controlling wireline pressure control equipment used in the exploration, production and/or exploitation of hydrocarbons, the wireline pressure control equipment being for controlling pressure in a well and including a wireline grease inject having an operating pressure, the method comprising locating a first portion of a pressure control apparatus in relatively close proximity to the said wireline pressure control equipment, where the first portion has at least one fluid pressure outlet coupled to the said wireline pressure control equipment and at least one controlling mechanism to facilitate control of the fluid pressure outlet, and locating a second portion of the pressure control apparatus in relatively spaced proximity from the said wireline pressure control equipment, where the second portion has a control system which operates the controlling mechanism of the first portion, wherein the method further comprises obtaining pressure signals from the well and automatically adjusting the operating pressure of the wireline grease inject so that it operates at a higher pressure than the well pressure.

A pressure control apparatus comprising a first portion having at least one fluid pressure outlet and at least one controlling mechanism to facilitate control of the fluid pressure outlet, wherein the controlling mechanism is operable by a control system at least a portion of which is located remote from the first portion, and wherein at least one fluid pressure outlet is coupled to wireline pressure control equipment for controlling pressure in a well, the wireline pressure control equipment including a wireline grease inject having an operating pressure, wherein the controlling mechanism is operable by a computer controlled system, wherein the at least one controlling mechanisms comprise variable settings to enable variation of the operation of the at least one controlling mechanisms, and wherein the computer is pre-loaded with software which permits a user to alter the settings of the at least one controlling mechanisms, wherein the software instructs the computer to display gauges on a visual display unit (VDU) which relate to the settings of the control mechanism.

A pressure control apparatus comprising a first portion having at least one fluid pressure outlet and at least one controlling mechanism to facilitate control of the fluid pressure outlet, wherein the controlling mechanism is operable by a control system at least a portion of which is located remote from the first portion, and wherein at least one fluid pressure outlet is coupled to wireline pressure control equipment for controlling pressure in a well, the wireline pressure control equipment including a wireline grease inject having an operating pressure, wherein the controlling mechanism is actuated by at least one air valve.
