– World wide drilling is developing for oil, gas or water resources. Electric motors power 75% of the total drilling rigs installation, augmenting to 95% for the case of Romania. Monitoring diesel generators micro-power station and motors of the rig is the second important thing to do and complete the main task of drilling process monitoring. This paper describe a monitoring and control system ...

There are a number of developments where new dry tree platform drilling rigs are specified. In some cases the geographical location, number of wells to be drilled and the ongoing life of field intervention requirements lead to the need for a permanent rig installation. The majority of permanent offshore rig installations has in the main been confined to the N. Sea region. As a result there is a...

conclusions our results showed that only 17% of the measured points in the oil drilling rig floor were in safe area; 39% were in caution area and 44% were in danger area. in the camp facilities area, 51% of the points were in safe area, 38% were in caution area and 11% in danger area. the main sources of noise exposure in the rig floor area were power generators. materials and methods this was ...

This work is devoted to the investigation of oscillations in a drilling system using an induction motor with wound rotor as a drive. It is motivated by the problems of drilling rig failures in the oil and gas industry. The study is based on a modified version of the mathematical model of a drilling rig proposed by scientists from the Eindhoven University of Technology. The model of drilling rig...

During the petroleum well drilling operation many mechanical and hydraulic parameters are observed by an instrumentation system installed in the rig named mud-logging system. The mud-logging system is composed by several sensors distributed in the rig; these sensors measure different operation parameters like: hook load, column rotation, mud pit level, pumping pressure, etc. The mudlogging syst...

Previous economic analyses focused on relationships between crude oil and natural gas markets centered primarily on demand-side considerations. We provide evidence that two important supply-side connections play important roles in understanding crude oil and natural gas market integration. First, crude oil production and natural gas production require a common capital input: rotary drilling rig...

The most costly operation in the oil exploration is the well network drilling. One of the most effective ways to reduce the cost of drilling networks is decreasing the number of the required wells by selecting the optimum situation of the rig placement. In this paper, Balas algorithm is used as a model for optimizing the cost function in oil well network, where the vertical and directional dril...

The handling of complex machines such as redundant manipulators requires appropriate control systems in order to make the operating of the system easier and to reduce processing time. This paper presents an advanced control system for a drilling rig used in tunnel construction which is currently under development in cooperation with an industrial partner. The drill rig is equipped with two redu...
