..., Nuclear magnetic resonance (NMR) logging is a geophysical method to directly detect the fluid properties of reservoir pores. NMR while drilling technology is to obtain the pore medium parameters for permeability, and saturation. It can be used for porosity logging, bound water logging, permeability...

... and a handful of operators. This model has remained the same for decades in contrast to technology already been deployed in drilling for instance, where a fully closed loop directional drilling system has automated the trajectory drilling service. This paper describes a remote wireline logging solution...

... ABSTRACT A well was drilled to target turbiditic channel sands of the Schiehallion field. The horizontal well was drilled from east to west to link multiple channel elements within the seismically mapped reservoir envelope. There were several challenges associated with the well, including...

... of holes are drilled, each generally less than 60 metres. Assays (geological analysis of material collected from the hole) are the primary reference data. Costs to log are low and many processes (data interpretation, delivery of logs, etc.) are automated. Next we will review how gamma ray, density, neutron...

There is a very narrow drilling window and reservoirs are drilled with high overbalance. Sensitive shales make borehole...

... ABSTRACT Borehole imaging at the time of drilling has been available since the first azimuthal tools were designed and put into use in the 1990s. In water-base muds (WBM), numerous improvements in both the resolution and quality of images have been made, particularly in microresistivity...
