Publication number: 20240048277Abstract: The technology is directed to the use of a bitmap generated at a receiver to track the status of received packets sent by a transmitter. The technology may include a network device including an input port, output port, and circuitry. The circuitry may generate a transmitter bitmap that tracks each data packet sent to another network device. The circuitry of the network device may receive, from the other network device, a receiver bitmap that identifies each data packet that is received and not received from the network device. The circuitry may then determine which data packets to retransmit by comparing the transmitter bitmap to the receiver bitmap.Type: ApplicationFiled: August 3, 2022Publication date: February 8, 2024Inventors: Yuliang Li, Hassan Mohamed Gamal Hassan Wassel, Behnam Montazeri, Weihuang Wang, Srinivas Vaduvatha, Nandita Dukkipati, Prashant R.

Publication number: 20230185666Abstract: Aspects of the disclosure are directed to a low-latency, low-overhead fault tolerant remote memory framework, which packs similar-size in-memory objects into individual page-aligned spans and applies erasure coding on these spans. The framework fully utilizes efficient one-sided remote memory accesses (RMAs) to swap spans in and out using minimal network input/outputs (I/Os), with compaction techniques that reduce remote memory fragmentation. The framework can achieve lower tail latency and higher application performance compared to other fault tolerance solutions, at the cost of potentially more memory usage.Type: ApplicationFiled: December 6, 2022Publication date: June 15, 2023Inventors: Yang Zhou, Hassan Mohamed Gamal Hassan Wassel, Minlan Yu, Henry M. Levy, David E. Culler, Amin Vahdat

Patent number: 9238942Abstract: A system, method and computer-readable medium for developing an earth formation is disclosed. A tool conveyed in a borehole induces a stress in the earth formation proximate a borehole. A sensor assembly obtains a measurement of a physical property of the borehole at a plurality of azimuthal locations in the borehole. The values of the physical property are indicative of the induced stress in the formation. A processor forms an image of the borehole using the obtained measurements of the physical property, estimates an azimuthal variation with borehole depth of the induced stress in the formation from the formed image, and alters an operational parameter of a device for developing the earth formation using the estimated azimuthal variation with depth of the induced stress in the formation.Type: GrantFiled: April 23, 2012Date of Patent: January 19, 2016Assignee: Baker Hughes IncorporatedInventors: Daniel Moos, Gamal A. Hassan, Daniel T. Georgi, David A. Castillo, John Fabian

Patent number: 8190369Abstract: A system and method for the geomechanical steering of the orientation of a wellbore is disclosed. In one embodiment, any available a priori data regarding the stress characteristics of a region of interest are used to develop a preliminary stress model for the region. A geosteered drilling operation is thereafter commenced, with the trajectory being steered in a direction relative to the stress model of the region. While drilling, real-time data is obtained from conventional down-hole instrumentation. The real-time data is used to refine the stress model for the region, such that the trajectory can be guided on an ongoing basis to achieve an optimal relationship with the measured stress characteristics of the region.Type: GrantFiled: August 4, 2008Date of Patent: May 29, 2012Assignee: Baker Hughes IncorporatedInventors: Daniel Moos, Gamal A.

Patent number: 8015868Abstract: Caliper measurements made during rotation of an imager on a logging string are processed to estimate the location of the imager, and size and shape of the borehole. A piecewise elliptical fitting procedure may be used. These estimates may be used to correct measurements made by a standoff-sensitive formation evaluation sensor such as a neutron porosity tool. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.Type: GrantFiled: March 19, 2008Date of Patent: September 13, 2011Assignee: Baker Hughes IncorporatedInventors: Gamal A.

Patent number: 7647182Abstract: The present invention provides a method and apparatus for logging an earth formation and acquiring subsurface information wherein a logging tool is conveyed in borehole to obtain parameters of interest. The parameters of interest obtained may be density, acoustic, magnetic or electrical values as known in the art. The parameters of interest may be transmitted to the surface at a plurality of resolutions using a multi-resolution image compression method. Parameters of interest are formed into a plurality of Cost Functions from which Regions of Interest are determined to resolve characteristics of the Features of interest within the Regions. Feature characteristics may be determined to obtain time or depth positions of bed boundaries and borehole Dip Angle relative to subsurface structures, as well borehole and subsurface structure orientation. Characteristics of the Features include time, depth, and geometries of the subsurface such as structural dip, thickness, and lithologies.Type: GrantFiled: January 13, 2006Date of Patent: January 12, 2010Assignee: Baker Hughes IncorporatedInventors: Gamal A.

Patent number: 7596452Abstract: A logging-while-drilling density sensor includes a gamma ray source and at least two NaI detectors spaced apart from the source for determining measurements indicative of the formation density.

Patent number: 7424365Abstract: A data compression technique for MWD applications uses feature detection, extraction, followed by image compression for only the region(s) of interest. The detection approach processes data in real time. It triggers on the start and end of a feature without processing any further features. This provides feature detection with zero latency. Compressing only the region of interest provides data compression with both higher resolution and higher compression ratio.Type: GrantFiled: July 13, 2006Date of Patent: September 9, 2008Assignee: Baker Hughes IncorporatedInventors: Gamal A.

Patent number: 7295928Abstract: The present invention provides a method and apparatus for logging an earth formation and acquiring subsurface information wherein a logging tool is conveyed in a borehole to obtain parameters of interest. The parameters of interest obtained may be density, acoustic, magnetic or electrical values as known in the art. As necessary, azimuths associated with the measurements are obtained and corrections applied. The corrected data may be filtered and/or smoothed. The parameters of interest associated with azimuthal sectors are depth matched, resolution matched and filtered, and the acquisition effects removed. The data are denoised using a multi-resolution wavelet transform. The data acquired with separate transducers are resolution matched to obtain a resolution matched data series. Subsequently the resolution matched data may be further denoised using a multi-resolution wavelet transform.Type: GrantFiled: October 21, 2005Date of Patent: November 13, 2007Assignee: Baker Hughes IncorporatedInventors: Gamal Hassan, Andrew Kirkwood, Phil Kurkoski
