This less stress on the motor and BHAis a strong indication of potential life improvements. The torque signal has a slightly different criteria...

... to a condition of high/continuous-demand mode, as defined in IEC-61508 [ 15 ]. Therefore, the appropriate quantitative risk/reliability indicator to be evaluated for the well integrity function is the frequency of failure, which in the case of our workcorresponds to the instantaneous frequency of an uncontrolled...

... from the evaluation indicate periodic changes in water intake the various zones along the drilled interval over time. This may be due to variation in mobility and uneven pressurizing of the zones from the water injectivity. Abstract Logging-While-Drilling (LWD) formation testers have been...

... with an automated surface system. Different indicators such as vibrations, loads and ROP that are traditionally used for stringer detection have been analyzed in the development phase of the algorithm. High-frequency torsional oscillations (HFTO) have been found to be a leading indicator for stringer drilling...

... are efficiently transported to surface. The objective of this paper to present a real time automated model to obtain hole cleaning efficiency and thus effectively adjust parameters as required to improve drilling performance. The process adopts a modified real time carrying capacity indicator. There are many hole...

...Introduction In both workflows, we apply and test RMFinder to select the RS based on multiple simulation outputs (dynamic data). The simulation outputs considered in this study are divided into two main groups: Field indicators: net present value (NPV), cumulative oil production (NP...

... Abstract A previous study by the authors on synthetic fractal-fracture networks showed that lacunarity, a parameter that quantifies scale-dependent clustering in patterns, can be used as a proxy for connectivity and also, is an indicator of fluid flow in such model networks. In this research...

... speed decrease as the run progresses. This indicates the loss of motor efficiency due to the degradation of the mud motor. Without any mitigation action, worse drilling dynamics and surface and downhole equipment failures are likely to follow. This paper presents a new analysis method to estimate...

... Karlsen G. (2020) identified a list of well control events in his article which could be prevented by focusing on the well control barrier health indicators and taking informed decision timely. He recognized that the high consequence incidents happened as the left-hand side (or preventions side...

... system for detecting both static and dynamic sticking as friction increases while running into or pulling out of the wellbore. The system uses one-second surface drilling data to identify friction indicators in the axial and rotational directions based on data-driven analysis of time series data trends...

..., indicates the point in time lag where the signals are best aligned. Accordingly, the lag at this point is equal to the delay. As different variables have a significantly different range of values, we used normalized cross-correlation so that these coefficients will have a value of 1 at zero lag...

... Abstract The selection of a production strategy, seeking maximization of field performance according to some indicator, is a complex and important task. Choosing the indicator to be used to complete this task can lead to different results, and this choice must be carefully made to reflect...
