... model for predicting temperature and pressure changes with instrument uncertainties during the shut-in process, followed by application case studies with leak and no leak conditions. The results will be examined with regard to providing recommendations for leak sensitivity. INTRODUCTION The API 1149...

... as pressure changes. Also explored are the frictional effects that cause the pressure to drop. For example, how does the velocity influence the pressure drop and hence the temperature? The background behind the theoretical basis is described followed by an introduction to the Joule Thomson coefficient...
