摘要： There is disclosed a system for monitoring abandoned subsea wells with a Wet Christmas Tree (WCT) comprising a Control Module to be installed on a modified abandonment cap and a Communication Module coupled beneath the ROV to perform the communication with the control system of the Control Module by way of an electric jumper and supply hydraulic power to the control system by way of an hydraulic jumper. The system is useful for wells with a VCM or three VCMs. In this case, the modified abandonment caps are used. The monitoring method of the abandoned subsea wells with WCT is also described.

摘要： A fully electric downhole safety tool comprising a valve for flow blockage in oil and gas wells completion operations under emergency conditions is described. Valve comprises an actuation array constituted by a hollow shaft motor, nut, spindle and sliding sleeve, so that upon starting, the opening movement of said array compresses a valve closure spring and places the flapper sealing in the open position, enabling communication to occur between zones and fluid to flow. To close the valve, as soon as the electrical supply is ceased, the string relaxes, the sliding sleeve, under spring force, returns as is the case for the whole of the actuation array, and flapper sealing is exposed to the flow so that valve returns to the closed position, physically blocking the flow.

摘要： A valve-type electric tool for downhole flow control using a holo-shaft motor. Said valve comprises: a housing provided with an infinitely variable choke where in seals work as gaskets both the outside and inside of the valve; a hollow-shaft servomotor inside said housing attached to a nut, and, additionally, when said motor is activated, the motor directly moves a sliding sleeve provided with an infinitely variable choke axis-wise said valve; and in which the movement of said motor is generated by of a spindle, created on the very same said sliding sleeve, and in which said valve is operated from the surface by a single electric cable.

摘要： An electromagnetic-mechanical locking device applied to a subsurface safety valve comprising an electromagnetic-mechanical coupler formed electromagnet (4), ferromagnetic bulkhead (5) in solidarity to the mobile part (6), actuated by spring (9), in addition to locking element (7), and when activated, the electromagnet (4) creates a magnetic field that attracts the ferromagnetic bulkhead (5), along with the mobile part (6), moving this set towards the electromagnet (4), and compressing the locking element (7). During the movement, the mobile part (6) shifts the locking element (7) to the locking position, until it reaches its coupling on the flow tube (3), where it is maintained with compression locking element (7), configuring a trigger device. When the power supplied to the electromagnet (4) ceases, the electromagnetic attraction force of the ferromagnetic bulkhead (5) is cancelled, and the locking element (7), until then retracted, is distended, causing the return of the mobile part (6) to initial position.
