  • Publication number: 20200096429
    Abstract: Methods may include emplacing a downhole tool within a wellbore, sampling a fluid downhole with the downhole tool; analyzing the fluid, and calculating an interfacial tension (IFT), wherein calculating the acid-base IFT contribution comprises measuring a concentration of a surface-active species directly. Apparatuses for measuring an interfacial tension (IFT) in a fluid downhole may be part of a downhole tool and may include a sampling head to sample the fluid; and a downhole fluid analysis module that includes a spectrometer capable of measuring a concentration of a surface-active species in the fluid, and a processor configured to determine the IFT of the fluid downhole based on the measured concentration of the surface-active species.

  • Patent number: 10422207
    Abstract: Transverse fractures are formed from a borehole using hydraulic fracturing fluid while maintaining the downhole pressure close to a target pressure. The target pressure is selected to be greater than the expected transverse fracture initiation pressure at predetermined weak points, such as notches, and less than the expected longitudinal fracture initiation pressure. The process can be repeated to form multiple transverse fractures by pumping diversion composition(s).

  • Patent number: 10351751
    Abstract: A wellbore is internally sealed using nanoparticles. Permeability properties are determined for a particular formation, along with its pore throat size distribution. A wellbore internal sealant (nanoparticle treatment fluid) is designed based on the determined permeability properties and pore throat size distribution. The nanoparticle treatment fluid is introduced into the formation. Pore throats within the formation are plugged by nanoparticles in the nanoparticle treatment fluid. Internal sealing reduces leak-off from filtercake damage, and also eliminates build-up of surface filtercake. Sealing the pore-structure of a particular wellbore zone alleviates the need for additional lost circulation material, resulting in a very thin filtercake and significantly reducing the chance of differential sticking. Oil-based muds can be replaced with water-based equivalents.

  • Patent number: 10329855
    Abstract: A control line assembly and technique for fabricating the control line assembly are disclosed. The assembly includes drawn tubular segments through which a gas is flowed to purge contaminants. The outflow of contaminants due to the gas flow is monitored and the gas flow can be controlled and terminated when a sufficient quantity of contaminants has been extracted. The gas flow can be combined with a heat treatment cycle to further extract contaminants. The heat treatment cycle can include multiple heating stages that can be controlled based on the monitoring of the exiting contaminants.

  • Patent number: 10301934
    Abstract: A downhole densitometer is used to determine one or more characteristics of a flowing fluid. The densitometer has one or more downhole x-ray sources and one or more downhole x-ray detectors. A fluid is allowed to flow past the x-ray sources. X-rays emitted by the x-ray sources and that have travelled through the flowing fluid are detected by the x-ray detectors. Characteristics of the flowing fluid are determined based on the detected x-rays. The densitometer may also have reference detectors used to measure a reference signal. The measured reference signal is used to normalize source emissions. The densitometer may be used as a permanent monitor and it may be used in conjunction with other sensors such as a flow-rate sensor or a capacitance sensor. The x-ray source may be, for example, a pyroelectric source, a radioisotopic source, or a traditional x-ray tube source.

  • Patent number: 8326094
    Abstract: The sensor includes an optical waveguide defined in a light-transmitting medium. The waveguide includes a sensing portion and an non-sensing portion. The light-transmitting medium included in the sensing portion has defects that provide the light-transmitting medium with a deep band gap level between a valence band of the light-transmitting medium and a conduction band of the light-transmitting medium. The deep band gap level is configured such that the waveguide guiding light signals through the light-transmitting medium in the sensing portion causes free carriers to be generated in the light-transmitting medium. A detector is configured to detect the free carriers in the sensing region of the waveguide.

  • Patent number: 7386207
    Abstract: An integrated optical waveguide (1) having an in-line light sensor (2) integrally formed therewith for tapping off a small proportion of the signal transmitted along the waveguide (1). A first part (1A) of the waveguide leads to a photodiode portion (2) and a second part (1B) of the waveguide leads away from the photodiode portion (2), the photodiode portion (2) comprising one or more regions (14) of light absorbing material within the waveguide (1) arranged to absorb a minor proportion of light transmitted along the waveguide (1) and thereby to generate free charge carriers within the waveguide (1). Deep band gap levels (21) are introduced into photodiode portion by ion implantation to enable it to absorb selected wavelengths. The free charge carriers are detected by a p-i-n diode formed across the waveguide (1). Wavelength selective reflectors (11, 12) may be provided either side of the photodiode portion (2) so light passes repeatedly through the photodiode portion (2).
