... conventional technologies are used, there are difficulties in drilling entirely vertical bore holes and large diameter casings (e.g. 20 or 13 3/8 ) are extremely rigid, so a borehole with a much larger diameter than the casing has to be drilled during the surface and intermediate stages, to ensure the casing...

.... These techniques can enable us to identify heretofore invisible geologicfeatures, thus boosting reserves and production. Also, they lead to substantially reduced well costs, because better detail known before drilling minimizes ‘overdesign’ of boreholes, and greater detail available while drilling can be matched...

... system is the availability of a reliable communication channel with the bottom hole. This makes it possible to obtain a continuous information on the bit and EDM operation, borehole path parameters while providing the transmission of the power required for the rock destruction at the bottom...

.... The idea is not new. The concept of drilling horizontally into a reservoir to enhance production has intrigued innovators since the late 1920's. In the mid-to-late 1950s numerous short-radius horizontal boreholes were drilled in the US to promote additional drainage in tar sands and other lowpressure...

... Abstract. As the search, exploration and development of oil and gas fields becomes more and more complicr.ted involving greater well depths and the necessity of investigating complex reservoir formations, the borehole geophysicist has been facing problems frequently insoluble with standard...

... Abstract. Active seismic probing of rock formations containing gaseous or liquid fractions is limited by a requirement for repeatable, nondestructive sources of high frequency seismic energy. When borehole access is available it is preferable to put both the source and the receiver well under...
