Patent number: 11970934Abstract: Multi-phase measurements of a fluid in a wellbore can be received and stored by a memory tool for determining flow characteristics of fluid flowing in the wellbore. A system can include a flow meter device, one or more sensors, and a memory tool The flow meter device can include one or more acoustic devices that can be positioned to generate acoustic signals in a wellbore. The one or more sensors can be positioned to detect the acoustic signals from the flow meter device for making multi-phase measurements of fluid with respect to the wellbore. The memory tool can be communicatively coupled to the one or more sensors to receive and store the multi-phase measurements for a predetermined amount of time for determining flow characteristics of the fluid.Type: GrantFiled: June 3, 2022Date of Patent: April 30, 2024Assignee: Halliburton Energy Services, Inc.Inventors: Mikko K.

Patent number: 11959887Abstract: An asymmetric fluidic oscillator can generate acoustic signals in a wellbore. The asymmetric fluidic oscillator can include an inlet housing defining an inlet channel, a feedback system, and an outlet housing defining an outlet channel. The inlet channel can be sized to receive fluid from the wellbore. The feedback system can be coupled to the inlet channel to oscillate the fluid from the wellbore. The outlet channel can be coupled to the feedback system and can be sized to receive the oscillated fluid from the feedback system. The outlet channel can include an asymmetric feature to generate acoustic signals detectable in the wellbore.Type: GrantFiled: June 3, 2022Date of Patent: April 16, 2024Assignee: Halliburton Energy Services, Inc.Inventors: Mikko K. Jaaskelainen, Julian Drew, Benjamin Schaeffer

Publication number: 20230144034Abstract: A method can be used to determine multi-phase measurements of fluid flowing with respect to a wellbore. Signals can be received, and the signals can be emitted by each variable frequency acoustic emitter of a set of variable frequency acoustic emitters positioned spaced apart in a sensing transducer that is in an interior of a wellbore. The received signals can be converted into a flow rate of each of a set of different fluid phases of a fluid in the wellbore. The multi-phase measurements of the fluid can be determined using the converted flow rate.Type: ApplicationFiled: June 3, 2022Publication date: May 11, 2023Inventors: Julian Drew, David Diller, Werner Heigl, Richard Gibson, JR., Barry Fish

Patent number: 10641916Abstract: Seismic data processing using one or more non-linear stacking enabling detection of weak signals relative to noise levels. The non-linear stacking includes a double phase, a double phase-weighted, a real phasor, a squared real phasor, a phase and an N-th root stack. Microseismic signals as recorded by one or more seismic detectors and transformed by transforming the signal to enhance detection of arrivals. The transforms enable the generation of an image, or map, representative of the likelihood that there was a source of seismic energy occurring at a given point in time at a particular point in space, which may be used, for example, in monitoring operations such as hydraulic fracturing, fluid production, water flooding, steam flooding, gas flooding, and formation compaction.Type: GrantFiled: June 21, 2013Date of Patent: May 5, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Ali Ozbek, Julian Drew, Anthony Probert, Daniel Gordon Raymer
