... friction arising from both boreholes and perforated holes is reduced. The integration of rigless cementation and completion requires taking casing joints directly as fracturing strings, so there is neither perforated hole nor any subsequent friction. In horizontal borehole staged fracturing, the fracturing...

... deform to fit the borehole trajectory, which lead to its complicated contact geometry in the hole. The severity of dogleg and casing properties may make the formed annulus space so complex that prevent full placement of the cement around the casing, which can endanger well integrity in some occasions. We...

... al. 2017a, Xu et al. 2017b, Ren et al. 2017). Radial drilling-fracturing, combining radial drilling and hydraulic fracturing, is an innovative approach to remedy the above problems (Liu et al. 2017a, Guo et al. 2018). As shown in Fig. 1 , the radial borehole is drilled from the main wellbore...

...-in. (54-mm) diameter tools are passed through a 2.5 inch opening in the center of the bit face for logging deployment. Resistivity tools are normally run centered to minimize borehole effects, as compared to the nuclear tools which are eccentered to minimize standoff effects. In the through the bit...

Although the latter are much more uncertain, their greater number and spatial distribution mean that useful information about the rock permeability can be obtained. orientation information fluid pressure seismic...

The cuttings produced by polished cutters are half the size as standard ones even at more than twice the DOC enabling higher ROPs before the bit...

Both vector and curtain sections have display problems in areas of high dip or where the borehole is away from horizontal. In those cases, vector sections, which are constructed from dip-normal vectors combined...
