In this work, we introduce an innovative data-driven approach for liquid loading detection and prediction (LLDP) that harnesses high-frequency gas rate and tubing head pressure measurements to identify the onset of liquid loading and use...

... (EOR) and CO 2 sequestration. However, foams are thermodynamically unstable, and the stability properties need to be evaluated initially before introducing foam into the formations. In this study, we developed a novel approach to characterize foam using a multi-frequency dielectric technique...

This work presents a novel methodology for establishing the optimal logging frequencies required to maintain the integrity casing wall thickness of the primary flow string which serves as the leading indicator of casing integrity. In this study, metal loss data from magnetic flux-leakage logs run...

... than 30%, the supramolecular gel began to undergo different degrees of sol-gel phase transition, which showed that the energy storage modulus of supramolecular gel decreased. In addition, the energy storage modulus of supramolecular gel was always greater than the loss modulus in the whole frequency...

... is influenced either by the applied frequency or gas environment. The minimum energy required to initiate the flow increased with the applied frequency and was fairly altered by the change in the gas environment. remediation of hydrates asphaltene inhibition scale inhibition geologist asphaltene...

... is selected, the amount of tracer to be injected and the tracer sampling frequency are determined based on the distance between wells, mean traveling time, and the desired peak concentration. The tracer is injected as slug/continuous type to the selected injection wells and sampling from production wells...

... inaccuracy is common, and data-driven decisions may not be possible in a timely manner. We propose the use of radio frequency identification (RFID) for tracking oilfield tubulars and similar, outdoor-stored, equipment. Our proposed application utilizes passive ultra-high frequency (UHF) RFID technology...

Further risk reduction is accomplished thorough investigation of the different types of absorption attributes and enhancing the ANN training with petrophysical information derived from well logs. We demonstrate that the high frequency content of the seismic...

... Abstract Estimating inter-well connectivities based on injection and production rates has become increasingly popular, because it is an economical way to detect preferential subsurface flow trends. The techniques that adopt this idea all rely on the quality (accuracy and frequency...
