Method And Apparatus For Prediction Control In Drilling Dynamics Using Neural Networks
US Patent:
6732052, May 4, 2004
Filed:
Sep 28, 2001
Appl. No.:
09/965958
Inventors:
Robert P. Macdonald - Houston TX
Volker Krueger - Celle, DE
Vladimir Dubinsky - Houston TX
John D. MacPherson - Sugar Land TX

Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
G01V 140
US Classification:
702 6, 175 24
Abstract:
The present invention provides a drilling system that utilizes a neural network for predictive control of drilling operations. A downhole processor controls the operation of the various devices in a bottom hole assembly to effect changes to drilling parameters and drilling direction to autonomously optimize the drilling effectiveness. The neural network iteratively updates a prediction model of the drilling operations and provides recommendations for drilling corrections to a drilling operator.
Controlled Full Flow Pressure Pulser For Measurement While Drilling (Mwd) Device
US Patent:
2013004, Feb 28, 2013
Filed:
Aug 21, 2012
Appl. No.:
13/368997
Inventors:
Robert MacDonald - Houston TX, US
Gabor Vecseri - Houston TX, US
Benjamin Jennings - Houston TX, US
Gabor Vecseri - Houston TX, US
Benjamin Jennings - Houston TX, US
Assignee:
Teledrill, Inc. - Katy TX
International Classification:
E21B 21/08
US Classification:
175 38
Abstract:
An apparatus, method, and system described for generating pressure pulses in drilling fluid utilizing a flow throttling device which includes a controllable pulser operating sequentially within a downhole assembly within a drill string of a drill pipe. The system includes drilling fluid, fluid flow, and fluid drilling pump which when combined creates fluid flow into a bore pipe annulus within the downhole assembly creating a base line bore pipe pressure wherein bore pipe pressure is sensed via a sensor and information is sent to a Digital Signal Processor (DSP) that interprets the information. The DSP also receives information from an annulus pressure sensor that senses drilling fluid pressure as it returns to the pump. The DSP recognizes pressure variation input from the annulus pressure sensor and bore pipe pressure sensor and detects pressure variation providing signals as data information to the DSP, determining required action to adjust pulser operation.
Controlled Pressure Pulser For Coiled Tubing Applications
US Patent:
2013004, Feb 28, 2013
Filed:
Dec 23, 2011
Appl. No.:
13/336981
Inventors:
Robert MacDonald - Houston TX, US
Gabor Vecseri - Houston TX, US
Benjamin Jennings - Houston TX, US
Gabor Vecseri - Houston TX, US
Benjamin Jennings - Houston TX, US
Assignee:
Teledrill, Inc. - Katy TX
International Classification:
E21B 34/06, E21B 34/00
US Classification:
166373, 166319
Abstract:
An apparatus, method, and system for generating pressure pulses in a drilling fluid flowing within coiled tubing assembly is described that includes; a flow throttling device longitudinally and axially positioned within the center of a main valve actuator assembly that allows main exit flow fluid to flow past a drive shaft and motor such that the pilot fluid and the main exit flow fluid causes one or more flow throttling devices to generate large, rapid controllable pulses thereby allowing transmission of well developed signals easily distinguished from any noise resulting from other vibrations due to nearby equipment within the borehole or exterior to the borehole, or within the coiled tubing assembly wherein the signals also provide predetermined height, width and shape of the signals.
Drilling System With Integrated Bottom Hole Assembly
US Patent:
6206108, Mar 27, 2001
Filed:
Oct 22, 1997
Appl. No.:
8/955930

Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
E21B44/00;47/00
US Classification:
175 24
Abstract:
The present invention provides a drilling system that utilizes an integrated bottom hole assembly. The bottom hole assembly contains sensors for determining the health of the bottom hole assembly, borehole condition, formation evaluation characteristics, drilling fluid physical and chemical properties, bed boundary conditions around and in front of the drill bit, seismic maps and the desired drilling parameters that include the weight on bit, drill bit speed and the fluid flow rate. A downhole processor controls the operation of the various devices in the bottom hole assembly to effect changes to the drilling parameters and the drilling direction to optimize the drilling effectiveness.
Wastewater Treatment Process
US Patent:
5386079, Jan 31, 1995
Filed:
May 19, 1992
Appl. No.:
7/885413
Inventors:
Robert E. Munson - Baton Rouge LA
Robert D. Macdonald - Houston TX
Robert D. Macdonald - Houston TX
Assignee:
Ciba-Geigy Corporation - Ardsley NY
International Classification:
A62D 300, B09B 300, A61L 1100, C02F 168
US Classification:
588205
Abstract:
Wastewaters which are contaminated with heterocyclic aromatic compounds, especially wastewaters contaminated with biocidal heterocyclic aromatic compounds, or the by-products and intermediates thereof, can be treated to largely or even substantially completely degrade the heterocyclic aromatic rings by a process which comprises either adjusting the pH of said wastewaters to at least 11 and heating in a sealed vessel at a temperature of 120. degree. C. to 175. degree. C. , or adjusting the pH of said wastewaters to 2. 5 or less and heating in a sealed vessel at a temperature of 130. degree. C. to 175. degree. C. , for an effective length of time.
