摘要： A service tool and methods for performing subterranean hydrocarbon services in a wellbore. The service tool can include a body that having an aperture formed therethrough. A valve system can be connected to the body. The valve system can selectively form a flow path between a first portion of the aperture and a second portion of the aperture; a flow path between a first flow port formed through a first portion of the body, the aperture, and the outer diameter of the body; and/or a flow path between a channel formed in a portion of the body, a second flow port formed through a second portion of the body, and the second portion of the aperture.

摘要： The present invention relates to a method and apparatus for detection of hydrogen sulfide in downhole operations. A downhole tool is provided with a coupon adapted to react at varying degrees to exposure to concentrations of hydrogen sulfide. The downhole tool is positioned in the wellbore with the coupon(s) exposed to downhole fluids. A reaction to a change in the coupon, such as coloration, is used to determine the presence and concentration of hydrogen sulfide.
