Abstract
PHASE I OF THE PROPOSED RESEARCH WILL INVESTIGATE THE FEASIBILITY OF ASSESSING THE WEAR LEVEL OF AN OIL-WELL DRILLBIT DURING THE ACTUAL DRILLING PROCESS, BASED SOLELY ON PROCESSING SURFACE VIBRATION DATA. A RELIABLE AND INEXPENSIVE BIT WEAR SENSING SYSTEM WOULD READILY BE ACCEPTED AND IMPLEMENTED BY MOST DRILLING OPERATORS IN ORDERTO: (1) MINIMIZE UNNECESSARY DOWNTIME RESULTING FROM THE RETRIEVAL OF "GREEN" BITS, (2) MINIMIZING THE CATASTROPHIC FAILURE OFTEN RESULTING FROM THE CONTINUED USE OF A WORN BIT, AND (3) DETERMINING OPTIMAL DRILLING SPEEDS. DUE TO THE HIGHLY "NOISY" NATURE OF SURFACE DRILLING MEASUREMENTS, ADVANCED SIGNAL PROCESSING TECHNIQUES WILL BE USED TO DEVELOP A RELIABLE AND ADAPTIVE BIT WEAR ESTIMATION SYSTEM WHICH CAN COPE WITH THE HIGHLY "INAUSPICIOUS" AND UNPREDICTABLE DRILLING ENVIRONMENT. THE PROPOSED SYSTEM WOULD PROVIDE A LOW COST ALTERNATIVE TO BIT WEAR ESTIMATION SCHEMES TO BE PROVIDED IN THE NEAR FUTURE BY MOST COMMERCIAL MWD SYSTEMS, WHICH WOULD RELY ON DOWNHOLE SENSORS. ALTHOUGH THE PERFORMANCE OF THE LATTER WOULD BE SUPERIOR TO THAT OF THE PROPOSED APPROACH, THE COSTWOULD BE SUBSTANTIALLY HIGHER AND IN FACT PERHAPS PROHIBITIVE FOR MANY SMALL RIG OPERATORS.
