May 1, 2023 · This paper has demonstrated that estimating ROP downhole using machine learning is a viable method to enable downhole position control with fast control loops. An important consideration is how the error of the estimate impacts the processes using the estimate.
Dec 1, 2022 · Drilling a well is a dynamic process to reach the target formations. During drilling, many surface and downhole parameters are routinely measured and recorded, such as ROP, torque, RPM, weight-on-bit (WOB), etc. These parameters help drillers monitor the drilling, and then make real-time decisions to optimize drilling or detect anomalies.
Aug 1, 2024 · By providing real-time downhole pressure data, these sensors enable the drilling crew to promptly make well-informed decisions, thereby enhancing operational efficiency and reinforcing well...
5 days ago · Before the introduction of machine learning (ML) algorithms, reservoir parameter inversion was performed using linear regression and plate associations (App, 2017). However, these methods have low practical prediction reliability, owing to the nonlinear relationship between reservoir parameters and logging data ( Bai et al., 2022 ; Li et al., 2023a , Li et al., 2023b ).
Oct 19, 2020 · With high-speed telemetry and processor downhole, the system has the capability to process and analyze raw sensor signals at the bit, improving the data transmission rate, actuation delay, and response time.

Feb 20, 2021 · The analytical model (e.g., differential equation)-based methods have been extensively studied to identify downhole conditions and diagnose downhole faults [10]. A fault diagnosis model was developed by estimating the friction parameters of drilling fluid systems using nonlinear observers [11].
