Automated Evaluation of Hole Cleaning Efficiency While Drilling Improves Rate of Penetration

, 2020
Hole cleaning of drilled hole section of planned oil or gas well is considered as a major part of optimization of rate of penetration (ROP). ROP significantly depends on hole cleaning of drilled hole section.

Evaluation of a Drill Bit Button Arrangement for Enhanced Drilling Efficiency

Transactions of the Korean Society of Mechanical Engineers A, 2015
The drill bit, which directly transmits percussive forces and torque to the rock, is the core part of a rock drilling machine. For effective drilling, the button arrangement of a drill bit should be optimized because it is the most important design factor in determining drilling efficiency.

Efficiency of percussive drilling of rock with a bent drill rod

International Journal of Impact Engineering, 1994
Summary Wave propagation and efficiency in percussive rock drilling with a bent rod is studied theoretically using a combined approach of FFT and matrix method. The bent drill rod is represented by straight uniform elements. The extensional and flexural stress waves in the drill rod are described by the one-dimensional wave equation and by Euler ...

Increased Drilling Efficiency of Gas-Storage Wells Proven Using Drilling Simulator

CIPC/SPE Gas Technology Symposium 2008 Joint Conference, 2008
Abstract Gas storage wells are being drilled in Nova Scotia, Canada for natural gas storage in underground rock and salt caverns. A study was performed to evaluate the efficiency of the drilling of these wells. Utilizing a drilling simulator where drilling operational or log data is required to generate a drillability log or apparent ...

The Efficient Control of Twist Drills

Aircraft Engineering and Aerospace Technology, 1946
ONE of the noticeable effects of the extensive application of drill jigs is a steady decline in the number of fully qualified hands. Too many operators are jig specialists and quite unable to handle anything else. This is hardly a matter for surprise. After all, the main function of a jig bushing is to control the movements of the drill, and to anyone ...

Drill String Torque Reducing Technology Improves Drilling Efficiency in Horizontal Well

SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition, 2015
Abstract Horizontal wells have proven highly beneficial to the Oil and Gas Industry by enabling operators to tap into reservoirs previously deemed inaccessible by conventional drilling practices. This inaccessibility was particularly evident when drilling unconventional reservoirs; the efficient penetration and successful production of ...
