Drilling Parameters Optimization
2020Relationships between drilling parameters of weight on bit, rotary speed, tooth and bearing wear, hydraulic power, and rate of penetration (ROP) as well as drilling bit wear are first analyzed. After that, the method of optimizing mechanical drilling parameters is presented.

Study on Critical Drilling Parameters for Auger Drilling
Advanced Materials Research, 2011Auger drilling is widely employed in pile foundation engineering and sampling test for geological sciences, and is even considered as one of the idealest methods for space sampling. However, in practice, drilling parameters are usually determined by experience which might cause unnecessary accidents as a result of transportation blocking of chips.

Optimization of Drilling Parameters During Drilling with Casing in Unconventionals
Day 1 Mon, March 20, 2023, 2023AbstractDrilling with Casing (DWC) has been used in over 2200 strings in the last 10 years in Argentina and Bolivia. More than 1400 of the total strings were for surface casing applications.In Argentina and Bolivia, drilling with casing has been used extensively in mature fields and shale applications. In all the cases, the objective was to reduce cost

Parameters Estimation of Orthopedic Drill
2019 27th Signal Processing and Communications Applications Conference (SIU), 2019In medical drills, battery drills are highly preferred due to their comfort. Battery discharge during operation is a very important problem. For this reason, it is important to use the control method to minimize the energy consumption and to keep the drill speed in the desired range.

Publisher Summary Drilling rate is a function of weight on the bit, rotary speed, bit type, and size, hydraulics, bottom-hole cleaning properties of drilling fluid, and formation characteristics. Under controlled conditions of constant bit weight, rotary speed, bit type, and hydraulics, the drilling rate in shales decreases uniformly with depth. This

Optimizing Drilling Parameters Enhances Horizontal Drilling Performance
SPE/IADC Middle East Drilling Technology Conference, 2001AbstractThe optimized selection of bits and mud type during any drilling operation improves significantly the drilling efficiency presented in high rates of penetration consequently less cost per meter.Hydraulics play also great part in optimization cycle by enhancing the ratio of the pressure loss across the bit nozzles to the circulating pressure ...

Drill-bit displacement-source model: Source performance and drilling parameters
GEOPHYSICS, 2006The emission properties of a drill-bit source and the signature of the drill-bit seismograms depend on the dynamic action of the drill bit, which in turn is a function of the geological conditions, rock properties, and drilling parameters. In fact, drilling is a variable dynamic process, in which the vibrations produced by the drill bit are ...
