... water, and a maximum rate of 3.3 bbl/min was achieved. The bullheading of 275 bbl of fresh water at a wellhead injection pressure of 1,900 psi indicated that the open hole was taking fluid and a wellbore conditioning stage was not needed. Wellbore Drift and Prestimulation Assessment. The first CT run...

This paper describes the analysis of sidetracks drilled in an open hole by an annular ledge formation method with a downhole motor in multilateral wells. Introduction Currently, industry growth requires...

... environments. Most pulsed-neutron tools are run after casing; this study provides a unique opportunity to examine the effect of casing on spectroscopy by comparing casedhole measurements to measurements taken in the open hole before the casing was run. Introduction Pulsed-neutron logging has evolved over...

... shallow gas interval directly below a 22-in. shoe using MPD. A total length of 350 m of 22-in. open hole was drilled to the 18-in.-casing point. An unexpected high-pressure water/gas sand was encountered below the 22-in. shoe with a pore pressure of approximately 9.85 lbm/gal. The fracture pressure...

Once through this compressed stage, the offset bow centralizer will revert to its designed outer diameter in the open hole and thus maximize standoff without additional drag. The device achieves a reduction in drag compared with other centralizers because of its patented bow design...

... technologies, underbalanced drilling (UBD) and managed-pressure drilling (MPD) have emerged as solutions to specific hydraulics issues during drilling. A hydraulic parameter can be defined as any factor—mechanical, structural, or fluid—that affects the exertion of hydrostatic head on the open hole. Hydraulic...
