Mastering real-time and accurate downhole information is crucial for ensuring drilling safety, improving efficiency, maximizing economic benefits. In recent years, logging while (LWD) technologies, represented by mud pulse telemetry (MPT), achieved significant success. However, they still face challenges such as a large amount of conflicting with low transmission rates, severe channel distortio...

This report documents how we developed appropriate features and applied different algorithms to interpret flow rate, pressure and temperature data from permanent downhole gauges.

Abstract Currently, the main objective of oil operating companies is to increase drilling efficiency and minimize costs; this can be achieved in several ways. One them curtailment downhole events associated with trouble time by obtaining key factors that drive best proactive solutions terms cost effectiveness. From perspective, core focus paper present a detailed description develop an integrat...

The recently developed smart well technology allows for sectionalized production control by means of downhole inflow control valves and monitoring devices. We consider borehole radars as permanently installed downhole sensors to monitor fluid evolution in reservoirs, and it provides the possibility to support a proactive control for smart well production. To investigate the potential of borehol...

Abstract Cementing operations in wellbores, especially for long casings, are often challenging and prone to deficiencies when not properly planned executed. While exploring exploiting of geothermal resources at temperatures above the critical point water was attempted different drilling projects recent years, well design, procedure run cement production casings became a key challenge engineers....

A downhole seismometer at 900-m depth and a temporary network of surface stations were deployed to use rays from local microearthquakes to study the upper and middle crust beneath the Long Valley caldera. The downhole seismograms show S waves with high apparent amplitudes from earthquakes located 2-20 km to the south of the downhole seismometer. In contrast, S waves from earthquakes located in ...

In the process of geo-energy drilling, real-time vibration measurement drill pipes is significance for an understanding downhole conditions and properties rock. However, sensors used in areas at present require additional power sources, such as batteries, replacing batteries would significantly reduce production efficiency increase costs. our work, a new method using triboelectric nanogenerator...

At present, mud pulse transmission systems are widely used in downhole data transmission. But the systems are very low in transmission efficiency, only 5 10 bits/s, with very large anti-inter-symbol-interference (ISI). It cannot meet high requirements for high-speed transmission of modern logging system. The development of communication technology has laid some foundation for this requirement. ...
