Abstract: The present invention relates to a method for predicting the restart of paraffinic oil flow by being able to estimate the precipitated paraffin fraction under conditions of production stoppage through differential scanning calorimetry (DSC) tests and rheological evaluation, to predict the yield stress (TLE) profiles in pipes containing gelled paraffinic petroleum and the time interval until line blockage formation (available waiting time—TED).

Abstract: The present invention presents a system that allows mixing in a controlled way the streams exported by two-phase or three-phase separators, allowing the management of the phases according to the processing needs of the SPUs. The main idea is that the outlet streams of the subsea separation modules can be routed to different SPUs in order to optimize the processing capacity of the surface plant. It is capable of manipulating in real time process parameters such as GLR (Gas-Liquid Ratio), or GOR (Gas-Oil Ratio) or Water Cut (amount of water in oil) to generate the multiphase streams required by each SPU, using the own autogenous pressure of the process to carry out this adjustment, that is, without the need for pressure raising systems or artificial lifting (pumps, compressors, gas lift, etc.) of the export streams of the system. This is possible by means of a crossflow injection control system between the phases. However, the possibility of using pressure raising systems (pumps, compressors, etc.

Abstract: The present invention relates to the monitoring of disconnected subsea oil wells. In this scenario, the present invention provides a system for monitoring disconnected wells comprising (i) means for acquiring and processing (12) monitoring data from the WCT (20) and/or from the well, the means for acquiring and processing (12) being connected to the sensors of the WCT (20) and/or of the well, (ii) means for verifying (12) the monitoring data from the WCT (20) and/or from the well and comparing them with predetermined values, and (iii) means for signaling (14, 16) designed to send at least one signal in the event an abnormality is detected through comparison of the data with the predetermined values. The present invention further provides a method associated with the above-mentioned system.
