An apparatus for detecting a biomarker includes a particulate capturing structure for receiving and capturing exhaled breath aerosol (EBA) particulate from airway linings of a user, the particulate capturing structure having an aerosol particulate testing system for receiving the captured particulate and detecting a first biomarker, wherein the aerosol particulate testing system includes a dissolvable EBA sample collector film for capturing EBA particulate. The apparatus may include a droplet harvesting structure for converting breath vapor to a fluid droplet for forming a fluid sample and a testing system having a biomarker testing zone for receiving the fluid sample and detecting a biomarker.

A wearable electronic fabric comprises a woven fabric formed from a plurality of interlaced threads. The plurality of interlaced threads comprise a plurality of warp threads interlaced with a plurality of weft threads. The woven fabric has a top face and a bottom face. A plurality of conductive threads is included among the plurality of interlaced threads at predetermined intervals and interlacing angles to provide a pattern of connection locations. The connection locations are located at regular intervals on at least one of the top face and the bottom face of the woven fabric.

An apparatus for detecting a biomarker comprises a droplet harvesting structure for converting breath vapor to a fluid droplet for forming a fluid sample and a testing system having a biomarker testing zone for receiving the fluid sample and detecting a biomarker. The droplet harvesting structure may include at least one of a hydrophobic field for receiving the breath vapor and forming the fluid droplet from the received breath vapor and hydrophilic channels for receiving the fluid droplet and channeling the fluid droplet towards the testing system. A fluid dam member may be provided disposed between the droplet harvesting structure and the biomarker testing zone.

A slurry for treating a wellbore, comprising a base fluid and a plurality of pre-processed fiber flocks dispersed in the base fluid.

Pre-processed fiber flocks and methods of use thereof

A system for generating variable frequency tube waves includes a high pressure multiplex pump having a number of plungers, with each plunger operatively coupled to a suction valve on a suction side and a discharge valve on a discharge side. The suction valve or the discharge valve of a first one of the plungers includes an opening, such that the modified plunger on a discharge stroke pushes fluid through the opening in the suction or discharge valve. The system includes a tubular fluidly coupling the high pressure multiplex pump to a wellbore, and a pressure sensor that receives tube waves generated by the high pressure multiplex pump and reflected from the wellbore.

Methods of treating a subterranean formation penetrated by a well bore, by providing a treatment fluid comprising a blend including a first amount of particulates having a first average particle size between about 3 mm and 2 cm and a second amount of particulates having a second average size between about 1.6 and 20 times smaller than the first average particle size or a second amount of flakes having a second average size up to 10 times smaller than the first average particle size; by introducing the treatment fluid into the well bore; and by creating a plug with the treatment fluid.

Methods of zonal isolation and treatment diversion

A method of treating a subterranean formation, including obtaining information of a subterranean formation, generating a three-dimensional model of at least a portion of the subterranean formation, and performing an experiment on the three-dimensional model. The three-dimensional model may be constructed by x-ray scanning of a core of the subterranean formation, and by additive manufacturing using the obtained x-ray image. The subterranean formation may be treated using a treatment designed based upon the experiments performed on the three-dimensional model.

Method of treating subterranean formation

A method of well treatment includes establishing fluid connectivity between a wellbore and at least one target zone for treatment within a subterranean formation. The method includes injecting a treatment composition into the wellbore. The method includes contacting a subterranean formation with the treatment composition, providing a diversion agent to a desired interval in the wellbore and measuring a wellbore parameter while performing at least one of the contacting the target zone and the providing the diversion agent.

Method and system for treating a subterranean formation using diversion

A method well treatment includes establishing fluid connectivity between a wellbore and at least one target zone for treatment within a subterranean formation, which is intersected by a wellbore. The method includes deploying coiled tubing into the wellbore and introducing a treatment composition into the wellbore. The method includes contacting a target zone within the subterranean formation with the treatment composition, introducing a diversion agent through the coiled tubing to an interval within a wellbore and repeating the introduction of the treatment, the contacting of the target zone and the introduction of the diversion agent for more than one target zone.

Methods of making and using wellbore casing are described, one method comprising providing a plurality of flow-through passages in a portion of a casing while the casing is out of hole; temporarily plugging the flow-through passages with a composition while out of hole; running the casing in hole in a wellbore intersecting a hydrocarbon-bearing formation; and exposing the composition to conditions sufficient to displace the composition from the flow-through passages while in hole. Methods of using the casing may include pumping a stimulation treatment fluid through the casing string and into a formation through the flow-through passages in the first casing joint; plugging the flow-through passages in the first casing section; and exposing a second casing joint of the casing string to conditions sufficient to displace the composition from the flow-through passages in the second casing joint.
