Patent number: 11732572Abstract: Techniques for determining depths of provenance of drill cuttings contained in a drilling fluid received from a wellbore. The drilling fluid contains drill cuttings of different sizes that arrive at surface at different times, and the drill cuttings originate from different formation layers at different depths along the wellbore. Such techniques may include extracting samples of drill cuttings from the drilling fluid and repeating this step as necessary to provide samples of drill cuttings that arrive at surface at different recorded times; characterizing one or more formation attributes associated with the drill cuttings; and for each formation attribute, estimating a distribution of formation attribute characterization versus depth of provenance.Type: GrantFiled: March 4, 2022Date of Patent: August 22, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventor: Paul Simon Hammond

Patent number: 9581475Abstract: A multiphase flow meter comprising two Venturis separated by a choke. The choke may be varied to adjust the properties of the multiphase fluid flow being measured. The two Venturis may be identical and may be arranged horizontally with respect to the multiphase fluid flow. The choke may be a choke in a return line of a managed pressure drilling system.Type: GrantFiled: June 29, 2012Date of Patent: February 28, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Ashley Bernard Johnson, Paul Simon Hammond, Gary Martin Oddie, Cheng-Gang Xie

Patent number: 9528869Abstract: A method for compensating for changes in a property of water in a multiphase fluid during analysis of the multiphase fluid is provided. In one embodiment, the method includes providing a multiphase flow meter system configured to emit and detect nuclear radiation, to emit and detect microwave radiation, and to analyze a received multiphase fluid. The method can also include measuring a temperature and a microwave complex permittivity of the multiphase fluid. Further, the method includes compensating for changes in the property of water in the multiphase fluid during analysis of the multiphase fluid by using an empirical transformation between the fluid temperatures, microwave complex permittivities and nuclear mass attenuation coefficients for mixtures of different waters expected to be produced and received by the multiphase flow meter system. Additional systems, devices, and methods are also disclosed.Type: GrantFiled: December 16, 2014Date of Patent: December 27, 2016Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Cheng-Gang Xie, Paul Simon Hammond, Ian Atkinson

Patent number: 8770283Abstract: A method and system for acoustic monitoring using a fiber optic cable. The optical fiber is used as a distributed interferometer that may be used to monitor activity, such as activity with respect to a conduit, wellbore or reservoir. The distributed interferometric monitoring provides for accurate detection of acoustic occurrences along the fiber optic cable and these acoustic occurrences may include fluid flow in a pipeline or wellbore, processes taking place in a wellbore or pipeline, fracturing, gravel packing, production logging and/or the like.Type: GrantFiled: December 5, 2012Date of Patent: July 8, 2014Assignee: Schlumberger Technology CorporationInventors: Arthur H. Hartog, J. Ernest Brown, John Cook, Jonathan James Elphick, Paul Simon Hammond, Ashley Johnson

Publication number: 20130009048Abstract: An immersion probe is described that includes sensing elements that allow for hydrate inhibitor dosage to be more efficiently provided into gas and/or oil wells. The immersion probe allows for detection of first appearance of water in a multiphase flow in a well, measuring the amount of inhibitor in water within the well, determining an accurate water-cut, and measuring other property such as water salinity. Accordingly, with the known water-cut, salinity and the water flow rate inferred from the inhibitor injection flow rate and inhibitor-in-water fraction, a correct dosage of the inhibitor can be injected to the well in order to prevent hydrate formation, while reducing overdosing. Water flow rate may also be inferred from an independently measured liquid flow rate and the immersion-probe measured water cut.Type: ApplicationFiled: December 17, 2010Publication date: January 10, 2013Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Cheng-Gang Xie, Paul Simon Hammond

Patent number: 8347958Abstract: Acoustic monitoring is carried out using a fiber optic cable. Coherent Rayleigh noise generated by the transmission of a coherent beam of radiation through the fiber optic cable is detected, a phase of the coherent Rayleigh noise is measured and the measured phase is processed to identify an acoustic occurrence along the fiber optic cable. In certain aspects, an optical fiber serves as a distributed interferometer that may be used to monitor a conduit, wellbore or reservoir. The distributed interferometric monitoring provides for accurate detection of acoustic occurrences along the fiber optic cable and these acoustic occurrences may include fluid flow in a pipeline or wellbore, processes taking place in a wellbore or pipeline, fracturing, gravel packing, or production logging.Type: GrantFiled: June 20, 2012Date of Patent: January 8, 2013Assignee: Schlumberger Technology CorporationInventors: Arthur H.

Publication number: 20120160011Abstract: Methods and apparatuses for determining the steam quality at a subsurface location for a steam injection operation. The methods involve obtaining a total mass flow rate, measuring a vapor velocity at the subsurface location and a second parameter, determining a vapor density from the second parameter when the second parameter comprises a measurement other than a vapor density, generating a vapor mass flow rate as a function of the vapor velocity, the vapor density and the internal cross-section area of the conduit, and generating the steam quality at the subsurface location as a function of the vapor mass flow rate and the total mass flow rate.Type: ApplicationFiled: December 4, 2011Publication date: June 28, 2012Inventors: Andrew Colin Whittaker, Paul Simon Hammond
