Publication number: 20230279774Abstract: Methods for interpreting pressure transient tests and predicting future production for a well are provided. In one embodiment, a method for predicting future production includes beginning a pressure transient test within a well at a wellsite and obtaining pressure measurements of well fluid during the pressure transient test. The method can also include using the obtained pressure measurements to determine probabilistic estimates of input parameters of a pressure transient reservoir model while continuing the pressure transient test. Future production from the well can then be estimated based on the probabilistic estimates of the input parameters. Other methods and systems are also disclosed.Type: ApplicationFiled: May 24, 2023Publication date: September 7, 2023Inventors: Nikita Chugunov, Sukru Sarac, Kirsty Morton, Fikri Kuchuk, Terizhandur S.

Patent number: 11149544Abstract: A technique facilitates communication in a subsea well application. The technique involves deployment of a blowout preventer subsea control and telemetry system to a subsea location proximate a wellbore. The blowout preventer subsea control and telemetry system is coupled to both a blowout preventer system and a wireless telemetry system. The wireless telemetry system has a plurality of repeaters deployed along the wellbore. The blowout preventer subsea control and telemetry system is used both to collect data from the wireless telemetry system and to control operation of the blowout preventer system. For example, the blowout preventer subsea control and telemetry system may receive control signals from a surface system and also relay data to the surface system through a common communication line.Type: GrantFiled: December 19, 2016Date of Patent: October 19, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Benoit Deville, Arnaud Croux, Stephane Vannuffelen

Patent number: 10711601Abstract: A system and method to automate data acquisition in a wireless telemetry network optimizes data acquisition to best match a target data set that the user desires given the performance limitations of the telemetry network. The user defines the target data set by providing inputs regarding a target quality of the target data set relative to a data set that has been produced and stored by a communication node in the network. The performance limitations of the network are defined in a system operating envelope. A data acquisition cycle is then automatically initiated and propagated in the network to acquire an actual data set that is an optimal match for the user's target given the system operating envelope.Type: GrantFiled: June 28, 2019Date of Patent: July 14, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Sukru Sarac, Clement Probel, Stephane Vannuffelen, Andriy Gelman, Arnaud Croux, Elias Temer, Khaled Mouffok

Patent number: 10708869Abstract: An acoustic network is located in a formation traversed by a borehole having a pipe contained therein. The acoustic network includes a backbone network having a number of backbone modems engaging the pipe and acoustically communicating along the pipe using a first modulation technique. A number of end node modems acoustically communicate using a second modulation technique orthogonal to the first modulation technique. At least one of the backbone modems is a bridge hub modem that is coupled to both the backbone network and an end node modem and communicates with the backbone network using the first modulation technique and with the end node modem using the second modulation technique. The end node modems may have a hibernation mode defined by low energy usage with no transmission or receipt of data, and a transmission mode defined by transmission of data by the end node modem.Type: GrantFiled: January 30, 2017Date of Patent: July 7, 2020Assignee: Schlumberger Technology CorporationInventors: Arnaud Croux, Julius Kusuma, Stephane Vannuffelen

Patent number: 9790786Abstract: A network management system for a wireless communications network adaptively selects wireless modems to use in communicating messages between a control system and downhole equipment. The wireless modems are selected based on a monitored signal to noise ratio. The network management system may be centralized within the network or within a surface control system or can be decentralized so that a plurality of the wireless modems can adaptively determine routing in the network. The network management systems can be used in conjunction with a backbone network architecture to achieve further efficiencies in network throughput.Type: GrantFiled: June 2, 2016Date of Patent: October 17, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Arnaud Croux, Stephane Vannuffelen
