Publication number: 20030187582Abstract: A method of assaying work of an earth boring bit of a given size and design comprises the steps of drilling a hole with the bit from an initial point to a terminal point. A plurality of electrical incremental actual force signals are generated, each corresponding to a force of the bit over a respective increment of the distance between the initial and terminal points. A plurality of electrical incremental distance signals are also generated, each corresponding to the length of the increment for a respective one of the incremental actual force signals. The incremental actual force signals and the incremental distance signals are processed to produce a value corresponding to the total work done by the bit in drilling from the initial point to the terminal point. Using such a basic work assay, a number of other downhole occurrences and/or conditions can be assayed.Type: ApplicationFiled: April 26, 2002Publication date: October 2, 2003Applicant: Halliburton Energy Services, Inc.Inventors: William A.

Patent number: 5767399Abstract: A method of assaying the compressive strength of rock comprises testing a primary plurality of rock samples of similar lithology, at least some of which have different porosities, to determine, for each sample respectively, a value corresponding to compressive strength and a value corresponding to porosity. A first series of pairs of electrical compressive strength and porosity signals, the signals of each pair corresponding, respectively, to the compressive strength and porosity values for a respective one of the samples, is generated. These signals are processed by a computer to extrapolate additional such pairs of signals and generate a second series of electrical signals corresponding to compressive strength as a function of porosity. The second series of signals may correspond to unconfined compressive strength, and may be further processed, to generate a cumulative series of signals, using electrical adjustment signals corresponding to other conditions affecting the compressive strength of the rock.Type: GrantFiled: March 25, 1996Date of Patent: June 16, 1998Assignee: Dresser Industries, Inc.Inventors: Lee Morgan Smith, William A.

Patent number: 5704436Abstract: A method of regulating drilling conditions applied to a given well bit comprises assaying the compressive strength of the formation in an interval to be drilled by said bit. Wear of critical bit structure of the same size and design as in said given bit and which structure has drilled material of approximately the same compressive strength as that so assayed, is analyzed along with respective drilling data for the worn structure. From said analysis, a power limit for the respective compressive strength, above which power limit excessive wear is likely to occur is determined. Drilling conditions, such as rotary speed and weight-on-bit, at which the given bit is operated are regulated to maintain a desired operating power less than or equal to the power limit. Where several feasible rotary speed/weight-on-bit combinations may result in the desired operating power, these conditions are optimized.Type: GrantFiled: March 25, 1996Date of Patent: January 6, 1998Assignee: Dresser Industries, Inc.Inventors: Lee Morgan Smith, William A.
