    • This specification relates to tracking phone calls related to online content items. In general, one aspect of the subject matter described in this specification can be embodied in methods that include the actions of determining a probability that a call to a phone number resulted from a first interaction of a set of interactions. In general, another aspect of the subject matter described in this specification can be embodied in methods that include the actions of determining a rank score for an online content item, including for each call of a plurality of phone calls to the phone number, attributing the call to an online content interaction of a set of online content interactions; determining, using the rank score, whether to provide the online content item to a client device; and providing the online content item to the client device upon determining to do so using the rank score.

    • The present invention provides aqueous viscoelastic compositions comprising a cleavable surfactant and possibly also an electrolyte. The cleavable surfactants useful in the present invention comprise at least one weak chemical bond, which is capable of being broken under appropriate conditions, to produce oil soluble and water soluble products typically having no interfacial properties and surface activity compared with the original surfactant molecule. Further, the rheological properties of the aqueous viscolelastic composition are usually altered upon cleavage of the cleavable surfactant generally resulting in the elimination of the viscofying, viscoelastic and surfactant properties of the composition. Aqueous viscoelastic compositions in accordance with the present invention are suitable for use in oil-field applications, particularly for hydraulic fracturing of subterranean formations. Thus, the present invention also relates to a wellbore service fluid and a method of fracturing a subterranean formation. The present invention also concerns novel cleavable surfactants.
    • 本发明提供包含可切割表面活性剂和可能还有电解质的含水粘弹性组合物。 可用于本发明的可切割表面活性剂包含至少一种弱化学键,其能够在合适的条件下破碎,以产生与原始表面活性剂分子相比通常不具有界面性质和表面活性的油溶性和水溶性产物。 此外,水性粘弹性组合物的流变性质通常在切割可切割表面活性剂时改变,通常导致组合物的粘着粘弹性,粘弹性和表面活性剂的消除。 根据本发明的水性粘弹性组合物适用于油田应用,特别是用于地下地层的水力压裂。 因此,本发明还涉及井筒服务流体和压裂地层的方法。 本发明还涉及新颖的可切割表面活性剂。
