Get PriceThermal measurements indicate that borehole conditions were conductive prior to drilling and that heat flow through the basement section is essentially the same as that determined for the overlying sediments (Expedition 309/312 Scientists, 2006b; Shipboard Scientific Party, 2003). The lack of curvature in the temperature profile through the cased sedimentary section suggests that there is little or no fluid flow down the borehole, despite imposition of a cold column of fluid during drilling ...

Get Price2014-9-16 · This paper describes the application of a directional-drilling model to the phenomenon of wellbore spiraling and compares its predictions with field data. The spiraling tendency of a bottomhole assembly (BHA) is determined from a stability analysis of the delay differential equations (DDEs) that govern the propagation of a borehole.
Get PriceDrilling-induced borehole regularity would also alter the borehole normal condition at the borehole wall. In either case, it would affect the Stoneley response, making it less representative of a deeper formation, as the permeability at the mud-borehole interface would be drastically altered. Another effect comes due to the coupling of ...
