Abstract
In some embodiments, an apparatus [100] and a system, as well as a method and an article, may operate to transmit downhole data in a drilling fluid via fluid pressure modulation, and receive the downhole data at a fluid pulse receiver included in a conduit [104] coupled to a drill pipe downstream from a Kelly hose. Other apparatus, systems, and methods are disclosed.
Claims30
An apparatus, comprising:
- a length of conduit to form a portion of a drilling fluid flow path, the conduit including a drill pipe attachment and a first opening to define a first flow path area along the drilling fluid flow path;
- an orifice to reduce the first flow path area to a second flow path area defined by a second opening;
- and
- a fluid pulse receiver to receive modulated data propagated via pressure waves in a drilling fluid contained by the portion of the drilling fluid flow path.
