Appl. No.:

15/742373

Inventors:

- Sugar Land TX, US

Peter TILKE - Watertown MA, US
George Alan WATERS - Oklahoma City OK, US

International Classification:

G01V 1/52
G01V 1/48
G01V 1/46

Abstract:

Methods utilizing ultrasonic acoustic logging tools are provided for detecting thin formation layers that present markedly higher compliance than that of the surrounding rock in, for example, a laminated tight hydrocarbon-bearing formation. These layers may be interpreted as presenting potential interfacial and planes of weakness that may have bearing on the extent of a hydraulic fracture propagating across them.

International Classification:

C09K 8/528
C09K 8/524
C09K 8/54

Abstract:

Compositions may include an aqueous phase comprising an acid source; an oleaginous phase containing an oleaginous base fluid, a pyrrolidone solvent, a terpene solvent, and a cycloalkyl ketone; and a surfactant. Methods may include emplacing a fluid in a subsurface formation, the fluid containing an aqueous phase comprising an acid source; an oleaginous phase containing an oleaginous base fluid, a pyrrolidone solvent, a terpene solvent, and a cycloalkyl ketone; and a surfactant. Methods may also include adding a treatment fluid to a hydrocarbon fluid being transported in a pipeline, the treatment fluid containing an aqueous phase comprising an acid source; an oleaginous phase containing an oleaginous base fluid, a pyrrolidone solvent, a terpene solvent, and a cycloalkyl ketone; and a surfactant.
