The present invention relates to hollow hydrogel capsules. In various embodiments, the present invention provides a method of treating a subterranean formation with a hollow hydrogel capsule including a hydrogel shell including a hydrolyzed and crosslinked polymerized composition. The hollow hydrogel capsule also includes a hollow interior including at least one component of a downhole composition for subterranean petroleum or water well drilling, stimulation, clean-up, production, completion, abandonment, or a combination thereof. In various embodiments, the present invention provides compositions comprising the hollow hydrogel capsules and methods of making the hollow hydrogel capsules.

Hollow hydrogel capsules and methods of using the same

This present application relates generally to a testing device for selecting a surfactant during oilfield subterranean operation technologies. More specifically, the application relates to providing a testing device for selecting a surfactant depending on the interaction of the surfactant with a combination of variables, including the formation hydrocarbon, source water and formation mineralogy.

Method and apparatus for selecting surfactants

Techniques for determining a wellbore fluid constituent concentration include depositing a portion of a hydraulic fracturing fluid that includes a base fluid on a quartz crystal microbalance, the base fluid including a constituent; measuring an oscillation frequency of the quartz crystal microbalance based on the constituent of the base fluid; determining, with the quartz crystal microbalance, a mass of the constituent in the deposited portion of the hydraulic fracturing fluid; and based on at least one of the determined mass or the measured frequency, determining a concentration of the constituent of the base fluid.
