CVD Grown Hybrid MoSe2–WSe2 Lateral/Vertical Heterostructures With Strong Interlayer Exciton Emission

Advanced Materials, EarlyView.
A scalable bottom‐up CVD methodology, based on liquid transition metal salt precursors, is presented for the controlled growth of two high‐quality MoSe2–WSe2 heterostructures (HSs): purely lateral (HS I) and hybrid lateral/vertical (HS II), by simply adjusting precursor concentration.

DIAGNOSTICS OF DRILLING TOOL WEAR TO IMPROVE WELL DRILLING EFFICIENCY

Problems of Gathering Treatment and Transportation of Oil and Oil Products
Well construction in complex geological conditions, typical for hard-to-recover reserves, requires continuous improvement of technologies and methods for drilling process monitoring. One promising direction is casing-while-drilling (CwD) technology, which allows combining the processes of drilling and casing the wellbore.

New Drilling Technology for Hole Cleaning and Efficient Drilling

, 2020
Well integrity is an important safety aspect of a well. Lack of wellbore integrity can lead to challenges like wellbore collapse, stuck pipe, lost circulation and sloughing shales, which are all big problems for drillers. Loss of circulation and stuck pipe is a high cost problem and is affecting the drilling optimisation considerably.
