The Effect of Rheology on Rate of Penetration

SPE/IADC Drilling Conference, 1995
Abstract Field data have been collected and analyzed to 1) identify the characteristics of a drilling fluid that enhance rate of penetration, and 2) quantify the impact of particular fluid properties on rate of penetration. The information is being used to evaluate the economics of a fluid treatment program in order to deliver optimal ...

Market penetration rates of new energy technologies

Energy Policy, 2006
The market penetration rates of 11 different new energy technologies were studied covering energy production and end-use technologies. The penetration rates were determined by fitting observed market data to an epidemical diffusion model. The analyses show that the exponential penetration rates of new energy technologies may vary from 4 up to over 40 ...

Rate of Penetration of Phosphate into Muscle Cells

Acta Physiologica Scandinavica, 1940
Summary.Labelled sodium and labelled phosphate are injected simultaneously into the lymph sack of the frog and the distribution of the radioactive sodium and the radioactive phosphate between plasma and muscle of equal weights is determined. A constant partition ratio of the radioactive sodium is obtained after the lapse of about 20 minutes.

How To Improve Rate of Penetration In Field Operations

Proceedings of SPE/IADC Drilling Conference, 1996
Abstract A method has been developed that identifies which factors are controlling rate of penetration (ROP) in a particular group of bit runs. The method uses foot-based mud logging data, geological information, and drill bit characteristics, to produce numerical correlations between ROP and applied drilling parameters or other ...
