... and production of fines. The results can indicate whether or not the shale has sensitivity to water and can demonstrate the inhibitive nature of the proposed fluids. Testing was performed according to API RP 13I. Shale samples from various formations were obtained, and crushed to a sieve size of 5/10 mesh...

... underperformed relative to equivalent initial wells. In particular, a sidetrack to an early successful well, had very poor performance on initial start-up. The geometry of the original well and the sidetrack were simulated, together with various assumptions and sensitivities to formation damage. In the original...

... ABSTRACT All rocks are sensitive to changes in stress. In the Dulang Field sandstones, stress sensitivity is affected by differences in texture, mineralogy and clay type. In this study, we present the results of a study that shows how stress sensitivity is related to the make up of a rock...
