摘要： Disclosed is a mechanism for retracting the wedges of a rigid riser support, consisting of a cam holder crown, rods with rollers, a drive spindle, a hydraulic actuator and springs; this system can be driven by ROV or remotely. The system allows the reduction of the need for shallow diving and enables interconnections of rigid risers by keelhauling, promoting competitiveness with the flexible riser solution.

摘要： The present invention describes a hydraulic cement composition, process and use thereof, wherein the composition comprises a hydraulic cement composition with increased resistance against carbon dioxide (CO2) for application in reservoirs such as oil and gas and carbon capture and storage (CCS) wells; with improved performance of cement paste formulations as a material for application in primary, secondary cementing, recovery and/or plugging operations, of reservoirs/wells that operate with high CO2 content; as a technological alternative to guarantee the integrity of wells in CO2-rich environments for long periods of time, without any additional intervention to the already current operational procedures for cementing wells, and with cost reduction in relation to class G cement (currently, the main raw material); and sufficient chemical resistance to carry out enhanced oil (EOR) and gas (EGR) recovery by injecting high levels of CO2, increasing reservoir pressure throughout the extraction period of hydrocarbon reservoirs.

摘要： The invention presents a system and method for reducing pressure and draining the annulus of submerged flexible pipes, with application in all flexible pipe structures and in any industry that uses these types of pipes. Its objectives are to eliminate condensed water and reduce the partial pressure of CO2, thus restoring the integrity of the pipes. In addition, with the reduction of the pressure of the annulus gases, the operations of collection of the pipes can be carried out with greater speed, that is, in less time. The previous relief of the annulus pressure further reduces the risk of rupture of the outer cap during the operation, thus reducing the risk of exposing operators to the presence of harmful gases, when the pipe reaches the deck of the PLSV vessel.

摘要： The present invention relates to devices and methods for containing gas leaks in pipelines. In particular, the present invention describes a device for eliminating gas leaks by sealing a gas leak in an expansion joint arranged between two pipes misaligned with each other, the device comprising a metallic structure comprising a sealing blanket, in which the metallic structure and blanket fully enclose the expansion joint using cables. In addition, the present invention describes a gas leak elimination device for sealing a gas leak in an expansion joint arranged between two aligned pipes, the device comprising a sealing blanket, steel cables, straps and fastening elements to fully enclose the expansion joint.

摘要： The present invention relates to the composition of calcite impregnated with chemical tracer, process for obtaining the same and process for identifying the origin of scale through mapping the tracer incorporated in the calcite, which is added to a viscous gel-based mattress. The present invention further comprises the use of said composition to identify the source of calcium carbonate scale in a well. Thus, it is possible to verify whether the origin of the calcium carbonate in the scale formed in the production column comes from the material injected into the well. Once this occurrence is confirmed, it is possible to plan ways to mitigate scale formation through material to combat circulation loss, thus avoiding production losses associated with scale formation.
