On the Use of Ocean Tide Model Driver, TMD, as a Filter to Recover Reservoir Signal from Well Test Pressure History
Available to PurchasePublisher: Offshore Technology Conference
Paper presented at the OTC Brasil, October 24–26, 2017
Paper Number: OTC-28020-MS
... Abstract In many cases, the intensity of tide signal present in a pressure transient test is so strong as to render its interpretation unfeasible. This noise (from tide) to signal (from reservoir) ratio is a function of the transfer of tidal stresses to porous pressure as well as of some...

Formation Oil Characterization in Oil-Based Mud Environments Using Blind Deconvolution in NMR Data
Available to PurchasePublisher: Offshore Technology Conference
Paper presented at the OTC Brasil, October 24–26, 2017
Paper Number: OTC-28001-MS
... Abstract The low contrast between formation oil and oil-based mud (OBM) filtrate as well as noise associated in the signal can cause the T2 distribution for the different fluids to resemble each other, making it difficult to identify the formation fluid using nuclear magnetic resonance (NMR...
