... for which surface-measured parameters, such as CT weight and length and pumping pressure, are the only parameters available to monitor the operation's progress, CT telemetry systems provide real-time monitoring of downhole data such as pressure, temperature, depth, etc. The CT telemetry system described...

.... These could be operating restrictions, relatively low bandwidth and complicated installation with associated high implementation costs, all of which lead to increased barriers to deployment. This paper discusses a novel acoustic technology that allows downhole data transmission to the surface real time...

... downhole data including, cementing, tripping, depleted reservoir and completion operations. It can be readily understood that whilst these are concentrating on operations where real-time downhole data was not previously available it is clear that closing the loop back to drilling is entirely feasible which...

... Abstract Downhole high frequency sensors are heralding the era of big data in drilling and have already shown potential to significantly push the limits of drilling performance. Downhole data transmitted in real time can be used to optimally select parameters during drilling and optimize off...

... Abstract A recently developed 2 ⅛-in. intelligent coiled tubing (ICT) system combines real-time downhole data monitoring with the capability to simultaneously provide downhole power, significantly improving operational efficiency and accelerating well recovery in all types of CT operations...

... for identification purposes. Using a Bayesian approach with training supervised learning algorithms, vibrations were automatically classified with a success rate in excess of 90% when applied to high-frequency field datasets. machine learning classification downhole data Exhibition Upstream Oil & Gas...

.... By using downhole data in real time, this risk can be reduced and drilling performance can be significantly improved. This paper discusses the results of the latest field test program of an automated drilling system where direct closed loop control of machines performs drilling optimization tasks using...

...; good pump run lives; and relatively simple installation in the subsea environment. This paper shares the operating experiences and presents the lessons learned based on field performance of the HSPs on the Captain Field. captain field completion equipment downhole data artificial intelligence...

... in real time. Furthermore, the paper discusses factors constraining the use of the technology and gives an outlook on future developments in well intervention process optimization utilizing real-time downhole data. real time system drilling operation downhole data drilling data acquisition...

... the thin beds. As part of a more general programme we have investigated the potential of NMR measurements on saturated core, from two wells in the field, as indirect predictors of other parameters of petrophysical interest such as irreducible water saturation and permeability. plug downhole data...

... in both water based and oil based mud have been simulated. Surface and downhole data from full scale gas kick experiments have been used to verify the simulator. The data used are downhole annulus pressure data, surface pressures, mud flow rate out, pit gain and gas transport data. The measured gas influx...
