Three-dimensional wellbore analysis and visualization

Methods and apparatus for measuring sag properties of a drilling fluid using a rotary viscometer. An insert, or shoe, is placed at the bottom of the heat cup containing the fluid to be tested. A rotating cylinder is disposed within the fluid and solid particles are allowed to settle toward the bottom of the heat cup. The shoe incorporates a curved and inclined upper surface that directs the settled particles toward a well non-centrally located in the shoe. As the test is performed, fluid samples can be withdrawn from the well and analyzed. The samples can then be returned to the well and the test continued. The insert concentrates the settled solids into a single location, which increases the sensitivity of the test and provides a location for sample acquisition that is easily and repeatedly located, which allows for improved correlation with laboratory and flow loop results.

An apparatus is presented which simulates the circulation system through which a fluid is circulated in an oil well. The apparatus includes manually adjustable control means which simulate the circulation system controls used in the circulation of fluid through the oil well. The controls are interfaced with, and drive a digital programmable calculator which calculates the pressure and volume of fluid at a plurality of points in the oil well. The calculator in turn is interfaced with display means which simulate the circulation system instrumentation during the simulated circulation process. The apparatus additionally includes means for calculating a formation pressure which is randomly higher than the fluid pressure at the depth of the formation. Responsive to this increased formation pressure, the apparatus simulates the invasion of formation fluid into the well bore and simulates the reaction of the circulation system as the formation fluid is circulated to the surface. If the formation fluid is gas, the apparatus simulates the expansion of the gas as it is circulated to the surface. The apparatus further includes means for automatically, randomly changing a characteristic of the circulation system such as when a failure occurs at a point in the circulation system, thus simulating the action of the circulation system during such a failure. A time multiplier means is included to compress the time required to effect circulation of the fluid in the oil well. Audio means are provided to simulate the sound of the fluid pump, gas escaping from the circulation system, and to sound an error alarm in the event a pressure limit of the circulation system has been exceeded, or a blowout condition exists. An apparatus results which is particularly useful in training oil well personnel in the circulation of a fluid in an oil well, control of an oil well during drilling, circulating out a kick of formation fluid while preventing a blowout, and in recognizing a failure of a component of the circulation system during circulation of a drilling fluid.
