| 204 | Method for predicting rate of penetration using bit-specific coefficient of sliding friction and mechanical efficiency as a function of confined compressive strength | US11015899 | 2004-12-16 | US20060149478A1 | 2006-07-06 | William Calhoun; Hector Caicedo; Russell Ewy |
| A method for predicting the rate of penetration (ROP) of a drill bit drilling a well bore through intervals of rock of a subterranean formation is provided. The method uses an equation based upon specific energy principles. A relationship is determined between a bit-specific coefficient of sliding friction μ and confined compressive strength CCS over a range of confined compressive strengths CCS. Similarly, another relationship for the drill bit is determined between mechanical efficiency EFFM and confined compressive strength CCS over a range of confined compressive strengths CCS. Confined compressive strength CCS is estimated for intervals of rock through which the drill bit is to be used to drill a well bore. The rate of penetration ROP is then calculated utilizing the estimates of confined compressive strength CCS of the intervals of rock to be drilled and those determined relationships between the bit-specific coefficient of sliding friction μ and the mechanical efficiency EFFM and the confined compressive strengths CCS, as well as using estimated drill bit speeds N (RPM) and weights on bit (WOB). | ||||||

| 207 | Method for optimizing the bit design for a well bore | US09705569 | 2000-11-03 | US06879947B1 | 2005-04-12 | Kevin L. Glass |
| A drill bit is designed to achieve optimum performance in a specified drilling application defined by the drilling system, the formation to be drilled and the configuration of the bore hole. A depth of cut versus predicted torque for a basic bit configuration is evaluated for different configurations of the drill bit. A computer modeling program is used to obtain the predicted torque for the basic bit configuration, and its modifications. Features of the bit design are changed to achieve the lowest predicted torque for an optimum depth of cut. Presenting the computer analysis as depth of cut versus predicted torque for the bit design simplifies the design selection process. The formation being drilled may be evaluated by comparing actual torque with predicted torque for a given rate of penetration. The evaluation can be used to conform the computer model and determine formation properties. | ||||||

| The invention relates to a procedure for measuring the rate of penetration V.sub.F of a drill bit fixed to the lower end of a drill string lowered into a well. During an initial period, the well is drilled keeping, on average, the value of weight F of the drill string measured at the surface relatively constant, and the instantaneous values of the drill string rate of penetration V.sub.S and the weight F are measured at the surface at different successive moments. The value of the drill string average rate of penetration V.sub.SM at the surface is determined from the values of V.sub.S measured and the successive values of dF/dt of the first derivative with respect to time. The coefficient of apparent rigidity of the drill string during the initial period is then determined from the values of V.sub.SM, V.sub.S and dF/dt. Finally, the rate V.sub.F is calculated. | ||||||

The totalizer device continuously displays the total depth of the object in the well bore. | ||||||
| 215 | Continuous real time drilling penetration rate recorder | US837149 | 1986-03-07 | US4736297A | 1988-04-05 | Donald LeJeune |
| An apparatus for providing a real-time monitoring and readout of the drilling progress of a rotary drilled deep well or oil well is connected to the wire of a standard wire line measurement wire and monitors the length paid out as a drill string descends. Simultaneously the device monitors the drill operator's controls to detect the status of drill operation. Through a computer driving both a visual and a hardcopy graphic display the operation is provided with a real-time indication of the rate of drill penetration and the rate of change of the drill penetration rate, thus providing direct information as to passage through various strata. A preferred embodiment uses a cam equipped idler wheel to measure movement of the wire line, and monitors the drill operators control switch to detect drill operation. A computer creates a video readout on a standard CRT and a tracking graph on a chart recorder. | ||||||
| 216 | Core monitoring device with pressurized inner barrel | US6488 | 1987-01-23 | US4735269A | 1988-04-05 | Arthur Park; Bob T. Wilson |
| A well coring apparatus is provided with the capability for monitoring the length of the core in the inner barrel (32) of a core barrel (16) and the rate at which the core enters the inner barrel (32). The device includes a Sonic Core Monitor (78) which is disposed in the upper end of the inner barrel (32) and a piston (68) which is disposed in the lower end thereof. The inner barrel (32) is filled with a pressurized fluid. The Sonic Core Monitor (78) generates an ultrasonic pulse that is transmitted down to the surface of the piston (68) and reflected back up to the Sonic Core Monitor (78). The time between the transmitted and received pulse is then measured and distance determined therefrom. Both length of core and rate of core entry into the inner barrel (32) can then be determined. If the core is proceeding at too slow a rate, a valve (50) can be opened to allow drilling fluid to bypass the core barrel (16). This provides the surface operator with an indication that a jam has occurred. | ||||||

| 218 | Video borehole depth measuring system | US161190 | 1980-06-19 | US4610005A | 1986-09-02 | Joseph G. Utasi |
| A video system measures the position of the traveling block of a drilling rig to determine borehole depth and the rate of drill bit penetration. A television camera is arranged to track the vertical movement of the traveling block of a drilling rig between its uppermost and lowermost positional limits. An encoding unit is connected to the television camera. The output of the encoder indicates the block's position along its vertical path of movement. The output signal is processed to provide information such as borehole depth and drill bit penetration rate. The output may be in the form of an analog output to a dial indicator, a chart recorder or the like. The system is not subject to fouling or mechanical failure and the system, including the input sensor, may be located in its entirety remotely from the drilling rig. | ||||||
| 219 | Method and apparatus for logging inclined earth boreholes | US31245 | 1979-04-18 | US4282523A | 1981-08-04 | Arthur H. Youmans |
| An improved technique is provided for comparing the velocity of an elongated well logging instrument traversing an inclined earth borehole with the playout velocity of the well logging cable at the earth's surface to control both the cable hoist drum rotation and the rate of movement of the subsurface instrument and thus insure cable playout is in equilibrium with the logging instrument movement. Method and apparatus are described for detecting any reduction in movement of the logging instrument through the borehole and for reducing the velocity of the logging cable playout in response thereto by reducing drum rotation. Further, when the velocity of cable playout slows to a preselected value, a monitoring circuit generates control signals which actuate a means of power attached to or integral with the logging instrument which, upon initiation, apply a force to move the logging instrument upward or downward within the borehole. | ||||||
| 220 | Method and apparatus to measure the rate of advance of a drilling tool on a floating drilling installation | US819041 | 1977-07-26 | US4138886A | 1979-02-13 | Jean Lutz; Francois Besnard |
| The disclosure relates to measurement of the rate of advance of a drill bit from a floating drilling installation. The process includes joining a point of the drilling system, fixed in translation with the movement of the drill string, at the lower extremity of which is a drill bit, to a fixed point solid with the ground, by a cable of constant length passing through a pulley system fixed to the floating drilling installation, to measure the angular displacements of different pulleys of the pulley system and to derive from them magnitudes representing the rate of advance of the drill bit. This procedure, applied to a floating drilling system, eliminates the effect of vertical movements, that is swells or waves, from the measurements. | ||||||
