Patent number: 9217807Abstract: Systems and methods for identifying sanding in production wells using time-lapse sonic data. Formation anisotropy can be characterized in terms of shear moduli in a vertical wellbore, e.g., vertical shear moduli C44 and C55 in the wellbore axial planes and horizontal shear modulus C66 in the wellbore cross-sectional plane. Changes in formation anisotropy between different times can provide qualitative indicators of the occurrence of sanding in the production well. Before production begins, the horizontal shear modulus C66 is typically less than the vertical shear modulus C44 or C55 or both. At a subsequent time after sanding occurs, the horizontal shear modulus C66 is typically greater than the vertical shear modulus C44 or C55 or both. By comparing the shear moduli of the vertical wellbore at different times, it is possible to identify the occurrence of sanding in the production well using time-lapse sonic data.Type: GrantFiled: July 23, 2013Date of Patent: December 22, 2015Assignee: Schlumberger Technology CorporationInventors: Jiaqi Yang, Bikash K.

Publication number: 20150285936Abstract: A technique facilitates determination of fracture attributes through the recording and analyzing of borehole sonic data before and after a fracturing operation. The technique comprises generating broadband acoustic waves at an array of receivers based on output from a plurality of acoustic sources. The waveforms of the broadband acoustic waves are recorded and processed to estimate sonic signatures. The sonic signatures are then used to determine fracture attributes. In some applications, the data may be used to determine whether the fractures in the formation are filled with fluid or soft sediments. Information on the fracture attributes is output to a suitable system, e.g. a computer display.Type: ApplicationFiled: April 7, 2014Publication date: October 8, 2015Applicant: Schlumberger Technology CorporationInventors: Bikash K.

Publication number: 20150198032Abstract: Methods are disclosed for detecting fluid in at least one annulus around at least one casing installed in a borehole traversing a formation utilizing a sonic tool. The sonic tool is activated in the borehole and the received sonic waveforms are processed to obtain a dispersion plot. A reference dispersion plot is generated using a model of the borehole where the casing is well-bonded by cement. The obtained and reference dispersion plots are compared. An indication of fluid and in some cases, the specific radial location thereof is obtained based on the signature of the obtained plot as opposed to the reference plot. The methods are effective in doubly-cased boreholes using monopole and/or dipole sources.Type: ApplicationFiled: January 16, 2014Publication date: July 16, 2015Applicant: Schlumberger Technology CorporationInventors: BIKASH K.

Publication number: 20150119403Abstract: The invention provides the identification of the presence of mutant ROS protein in human cancer. In some embodiments, the mutant ROS are FIG-ROS fusion proteins comprising part of the FIG protein fused to the kinase domain of the ROS kinase. In some embodiments, the mutant ROS is the overexpression of wild-type ROS in cancerous tissues (or tissues suspected of being cancerous) where, in normal tissue of that same tissue type, ROS is not expressed or is expressed at lower levels. The mutant ROS proteins of the invention are anticipated to drive the proliferation and survival of a subgroup of human cancers, particularly in cancers of the liver (including bile duct), pancreas, kidney, and testes. The invention therefore provides, in part, isolated polynucleotides and vectors encoding the disclosed mutant ROS polypeptides (e.g., a FIG-ROS(S) fusion polypeptide), probes for detecting it, isolated mutant polypeptides, recombinant polypeptides, and reagents for detecting the fusion and truncated polypeptides.Type: ApplicationFiled: September 11, 2014Publication date: April 30, 2015Applicant: CELL SIGNALING TECHNOLOGY, INC.Inventors: Ting-Lei Gu, Meghan Ann Tucker, Herbert Haack, Katherine Eleanor Crosby, Victoria McGuinness Rimkunas
