Effect of penetration force on drilling efficiency for seabed drilling robot

2020 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), 2020
Seabed mineral resources have been discovered on the bottom of the ocean; to utilize them, samples must be obtained and analyzed. In this study, a seafloor robotic explorer that can excavate and sample seafloor soil is developed. In a previous study, we developed a drilling robot that could excavate 650 mm into the ground while being underwater.

Can Safety Improvement Increase Drilling Efficiency?

SPE/IADC Drilling Conference and Exhibition, 2011
Abstract The number one operational safety risk during the drilling and completion of a well is the risk of a kick becoming uncontrollable and the danger that can place on people, assets and environment. Another risk is the potential misdiagnosis of a kick and the ability to quickly and efficiently identify downhole anomalies.

Efficiency of releasing stuck drilling string

Azerbaijan Oil Industry, 2021
While drilling oil and gas wells, 10–15 % of open part of wellbore consists of permeable fractured reservoirs and horizons. Despite of it, 70–80 % of failures occurring in wellbore fall on the permeable suites. After sticking electrical measurement only upper interval is specified.

Hole Quality: Gateway to Efficient Drilling

Offshore Technology Conference, 2002
Abstract A high-quality wellbore is generally considered to have (1) a gauge hole, (2) a smooth wellbore, and (3) a wellbore with minimum tortuosity. This paper will demonstrate that wellbore spiraling is the primary contributor to poor hole quality and that almost every well contains some degree of spiraling unless
