ABSTRACT:
A well test apparatus in which a by-pass sleeve valve lands in a previously set packer. A lock mandrel assembly lands in the sleeve valve and carries a transducer fitting. A transducer is releasably carried in the fitting. Well conditions such as pressure may be sensed by the transducer and recorded or transmitted to the surface. By manipulation of casing pressure, the by-pass valve may be opened and closed to flow the well at high production rates with the transducer in place.
