... penetration rates. A novel gauge geometry was engineered to reduce drag and deliver a smoother borehole. This would provide less torque when sliding and beneficial gauge pad interaction with the borehole when in rotating mode. Field performance studies clearly demonstrate that matching TCC, an optimized...

... that the grain scale geometry of tight gas is responsible. Abstract In tight gas sandstone the productivity of a well is sometimes quite different from that of a nearby well. Several mechanisms for this observation have been advanced. Of interest in this paper is the possibility that a small change...
