A bottom hole assembly 10 for drilling a deviated borehole includes a positive displacement motor (PDM) 12 or a rotary steerable device (RSD) 110 having a substantially uniform diameter motor housing outer surface without stabilizers extending radially therefrom. In a PDM application, the motor housing 14 may have a fixed bend therein between an upper power section 16 and a lower bearing section 18. The long gauge bit 20 powered by the motor 10 may have a bit face 22 with cutters 28 thereon and a gauge section 24 having a uniform diameter cylindrical surface 26. The gauge section 24 preferably has an axial length at least 75% of the bit diameter. The axial spacing between the bit face and the bend of the motor housing preferably is less than twelve times the bit diameter. According to the method of the present invention, the bit may be rotated at a speed of less than 350 rpm by the PDM and/or rotation of the RSD from the surface.

This application relates to various methods and apparatus for rapidly obtaining accurate formation property data from a drilled earthen borehole. Quickly obtaining accurate formation property data, including formation fluid pressure, is vital to beneficially describing the various formations being intersected. For example, methods are disclosed for collecting numerous property values with a minimum of downhole tools, correcting and calibrating downhole measurements and sensors, and developing complete formation predictors and models by acquiring a diverse set of direct formation measurements, such as formation fluid pressure and temperature. Also disclosed are various methods of using of accurately and quickly obtained formation property data.

A dispensing system and apparatus for introducing contrast media intravascularly during catheterization procedures, which includes connected segments of tubing that serve as a flow path into the vascular system. A spike is provided at one end of a first segment of the tubing for "spiking" a bottle of contrast media. A stopcock is also provided in the first segment of tubing and a luer lock fitting is attached to the stopcock for connecting a second length of IV (intravascular) tubing fitted with a companion luer lock fitting. In a first preferred embodiment a top check valve is provided in the second segment of tubing, which terminates in the top of a reservoir. A second stopcock is connected to the bottom of the reservoir and a third length of IV tubing projects from the second stopcock and receives a bottom check valve and a second luer lock fitting for securing the bottom end of the third length of IV tubing to a conventional manifold. In alternative embodiments of the invention the top and bottom check valves are omitted from the dispensing system. When the dispensing system is operational, contrast fluid is allowed to flow into the reservoir by manipulating the top stopcock, from which reservoir it flows into the manifold by manipulating the second stopcock and is injected intravascularly into the body from the manifold during the catheterization procedure.
