An ecofriendly corrosion inhibitor composition and a method for inhibiting corrosion on a metal surface with the ecofriendly corrosion inhibitor composition are provided. The ecofriendly corrosion inhibitor composition includes 10-30 weight % of fatty acids derived from waste vegetable oils and 70-90 weight % of heavy aromatic naphtha. The fatty acids derived from waste vegetable oils include oleic acid, linoleic acid, and palmitic acid. In the method, the ecofriendly corrosion inhibitor composition is added to a hydrocarbon fluid exposed to the metal surface and the corrosion inhibitor composition inhibits corrosion on the metal surfaces.

An apparatus for simulating fluid loss through diverging fracture fronts includes a housing including an inlet and an outlet. The housing defines an inner volume. The housing can receive and sealingly retain fluid in the inner volume. The housing includes a plate defining an opening formed in an axial surface of the plate. The opening spans a longitudinal thickness of the plate and diverges in dimension along the longitudinal thickness of the plate. The plate is sealingly positioned within the inner volume of the housing between the inlet and the outlet to permit fluid flow from the inlet to the outlet through the opening and to prevent the fluid flow past a circumferential surface of the plate. The apparatus includes a fluidic pressure source fluidically coupled to the housing and configured to flow the fluid through the housing.

Simulating fluid loss through diverging fracture fronts

An apparatus to simulate fluid loss through vugs in formations includes a housing defining an inner volume, and having a first end and a second end. The inner volume represents an inner region of a wellbore formed in a formation containing a vugular loss zone. The housing can receive wellbore fluid within the inner volume. A first cover late, which sealingly covers the first end, represents a first volumetric boundary of the inner region of the wellbore. A second cover plate, which sealingly covers the second end, represents a second volumetric boundary of the inner region of the wellbore. An outlet in the second cover plate can be switched between open and closed states. The outlet in the open state represents a vug in the inner wall of the wellbore. The apparatus includes a pressure port configured to transmit fluidic pressure in a direction of gravity within the inner volume and to apply the fluidic pressure to the wellbore fluid within the inner volume.

A method of evaluating fluid sensitivity of a water-based muds on a shale rock. The method includes providing a sample of the shale rock from a portion of a formation, where the portion of the formation is positioned outside of a reservoir region. The sample of the shale rock is separated into a first portion and a second portion. The first portion is subjected to a UCS test for detecting a first uniaxial compressive strength (UCS) value (UCS). The second portion is converted into a prepared sample utilizing a test preparation procedure. The prepared sample is subjected to the UCS test for detecting a second UCS value (UCS). A fluid sensitivity index (FSI) is determined utilizing the detected UCSand USCvalues.
