Development and application of turbodrills in hot dry rock drilling
Hot dry rock HDR drilling Geothermal drilling Turbodrill Field application
2018/3/23
The strata of hot dry rock (HDR) are usually igneous rocks with high temperature which are challenging for drilling activities. This paper deals with the key technology and research of turbodrills, in...
Mathematical modeling of heat transfer in counter-current multiphase flow found in gas-drilling systems with formation fluid influx
Gas-drilling Temperature Prediction Influx Joule–Thomson Cuttings
2018/4/2
The performance of gas-drilling (drilling oil and gas wells with air, nitrogen, or natural gas) is very unpredictable in many areas due to lack of proper design of drilling parameters because of limit...
The spectrum of thermally stimulated currents in rock samples from KTB drilling:preliminary results
thermally stimulated depolarization currents (TSDC) KTB drilling rocks relation parameters
2015/9/28
The technique of thermally stimulated depolarization currents (TSDC) was applied to fine grained amphibolite rock samples extracted from KTB drilling. Each sample was cooled down to liquid nitrogen te...
Gas Hydrates in Marine Sediments:Lessons from Scientific Ocean Drilling
Gas Hydrates Marine Sediments Scientific Ocean Drilling
2015/7/24
Certain low-molecular-weight gases, such as methane, ethane, and carbon dioxide, can combine with water to form ice-like substances at high pressure or low temperature. These compounds, commonly calle...
Large Igneous Provinces and Scientific Ocean Drilling:Status Quo and A Look Ahead
Large Igneous Provinces Scientific Ocean Drilling Status Quo Look Ahead
2015/7/24
A rich mosaic of disparate crustal types characterizes the Earth beneath the sea. Although "normal" oceanic crust approximately 7-km thick is by far the most prevalent, abnormally thick oceanic-type c...
Mission-Specific Platforms for the Integrated Ocean Drilling Program
Mission-Specific Platforms Integrated Ocean Drilling Program
2015/7/24
Since the inception of the Deep Sea Drilling Project (DSDP) and during the Ocean Drilling Program (ODP), scien-tific ocean drilling has been almost wholly confined to outer-shelf water depths or great...
Past and Future Impact of Deep Drilling in the Oceanic Crust and Mantle
Past and Future Deep Drilling Oceanic Crust and Mantle
2015/7/24
Knowledge of the composition of oceanic crust is critical for calculating the fluxes of mass, heat, and volatiles from Earth's interior to its crust, oceans, and atmosphere. In the great debate over c...
D/V Chikyu:Riser Operations and the Future of Scientific Ocean Drilling
D/V Chikyu Riser Operations Future of Scientific Ocean Drilling
2015/7/24
Earth science disciplines focused on investigation of climatic, ecological, or tectonic change as recorded in geological deposits (e.g., paleoceanography, marine micropaleontology, paleoclimatology, p...
The year 1967 was spent preparing for Leg 1 of the Deep Sea Drilling Project (DSDP). Because it was believed that graduate students, instead of professors, would staff the continuous expeditions, I jo...
Introduction to the Special Issue on the Impact of the Ocean Drilling Program
Special Issue the Ocean Drilling Program
2015/7/24
Exactly one year before man landed on the moon, on July 20, 1968, another scientific undertaking began that was much less publicized but perhaps just as important in its ultimate contribution to scien...
SHALDRIL I and II: Drilling from the Research Vessel Icebreaker Nathaniel B. Palmer
Research Vessel Icebreaker B. Palmer
2015/7/15
Understanding of Antarctica's climate and ice sheet evolution remains fragmented due to a paucity of outcrops and drill cores that contain deposits from the Neogene (~ 23–2.6 million years ago), when ...
Uncontrolled Drilling: Exposing a Global Threat to Groundwater Sustainability
Groundwater Resources Contamination Drilling Well-Pooling
2013/3/19
Untold numbers of boreholes are drilled into the earth’s crust every year. Most constitute a potential threat to groundwater quality by creating a preferred pathway for contaminant migration. Some sol...
