20210254433 | WIRELESS ACTIVATION OF WELLBORE COMPLETION ASSEMBLIES - A completion section includes a base pipe defining a central flow passage, an injection port, and a production port. A fracturing assembly includes a frac sleeve positioned within the central flow passage adjacent the injection port, a sensor that detects a wireless signal, a first frac actuator actuatable in response to the wireless signal to move the frac sleeve and expose the injection port, and a second frac actuator actuatable based on the wireless signal to move the frac sleeve to occlude the injection port. A production assembly is axially offset from the fracturing assembly and includes a production sleeve positioned within the central flow passage adjacent the production port, a filtration device arranged about the base pipe, and a production actuator actuatable based on the wireless signal or an additional wireless signal to move the production sleeve to an open position where the production ports are exposed. | 2021-08-19 |
20210254434 | OIL WELL FLOWBACK WITH ZERO OUTFLOW - A method for recovering reservoir fluids from a target reservoir through a well includes analyzing formation properties of the target reservoir and of formation layers surrounding the target reservoir. A disposal zone is then selected within the target reservoir or the formation layers surrounding the target reservoir that is segregated from the reservoir fluids in the target reservoir. A well completion operation accesses the reservoir fluids in the target reservoir and directs flowback effluent from the well completion operation to the disposal zone using internal oil flooding equipment. | 2021-08-19 |
