Silicon Wafer Processing

2020-4-23  The sand (SiO2)is taken and put into a crucible and is heated to about 1600 degrees C – just above its melting point. The molten sand will become the source of the silicon that will be the wafer. Step 3: Making the Ingot A pure silicon seed crystal is now placed into the molten sand bath. This crystal will be pulled out slowly as it is ...

Artificial Lift Method - an overview ScienceDirect Topics

James F. Lea Jr, Lynn Rowlan, in Gas Well Deliquification (Third Edition), 2019 Abstract. Gas lift is an artificial lift method whereby external gas is injected into the produced flow stream at some depth in the wellbore. The additional gas augments the formation gas and reduces the flowing bottom-hole pressure, thereby increasing the inflow of produced fluids.

Preparation and Evaluation of Artificial Cores of ...

2020-9-28  Unconsolidated sandstone has the characteristics of poor cementation, loose structure, and low intensity. It is difficult to obtain representative cores, and coring from reservoirs is expensive. Thus, artificial cores have been widely used in core flooding experiments instead of natural cores. We found that, during the process of making artificial cores, formation water has an important ...
