Title: Fluid flow volumetric determination apparatus and method
Inventor: DURRETT MICHAEL G
IPC: B01D19/00
Filed: 1990-02-13
Abstract: FLUID FLOW VOLUMETRIC DETERMINATION        APPARATUS AND METHOD                            ABSTRACT    A system and method for obtaining a rapid determination of the volumetric flow rate of a multi-phase fluid stream comprised  of crude oil, water and gas.

Title: Borehole, as well as a method and an apparatus for forming it
Inventor: HALLUNDBAEK JORGEN
IPC: E21B43/00
Filed: 1990-04-12
Abstract: A borehole,  as well as a method and an apparatus for forming it A b s t r a c t A borehole (2) serves to produce e.g. hydrocarbons in a preferably soft or relatively soft underground formation (1),  such as chalk or sandstone.  The borehole (2) is surrounded  by  a  substantially  tubular  reinforcement shell (9), which consists of formation material so com-pressed that the solid components of the material are substantially crushed to particles, and these are bonded together  by  the  fluid  or viscous  components  of  the material and/or drilling mud. The borehole (2) is formed by first predrilling a small hole and then rolling said hole up to final borehole diameter by compressing the formation  so  that  a  reinforcement  shell  (9)  of  the desired thickness  is  formed.  A self-propelling drive assembly (5) with a plurality of driven, elastic rollers (6) is used for this process, said rollers successively rolling down the borehole wall (7) and transferring the pressure force and moment from the drill bit (3) to the wall (7). Hereby horizontal boreholes can be formed far deeper into shallow hydrocarbon-bearing strata of the type which are found e.g. in the underground below the North Sea, so that these can be exploited profitably.
