Abstract: Abstract Wellbore instability in shallow unconsolidated formations is a great challenge to deepwater oil and gas drilling operations. Traditional experimental methods for evaluating wellbore stability cannot effectively simulate the cementation and consolidation effects of the… read more here.

Abstract: Larger well diameters allow higher groundwater abstraction rates. But particularly for the construction of wells at greater depth, it may be more cost‐efficient to only expand the borehole in the target aquifer. However, current drilling… read more here.
