Recently, the technologies for global modeling of process oil well drilling have become widespread. Mathematical is used in design, virtual testing various equipment, simulations emergency situations, and personnel training. Complex includes simulation such phenomena as dynamics drill string its contact interaction with walls, flow fluid soil (considering influxes leakages), crushing by drill, ...

Abstract. Good project planning provides the basis for successful offshore well drilling projects. In this domain planning occurs in two phases: an onshore phase develops a project plan; and an offshore phase implements the plan and tracks actual progress compared to the initial plan that was created onshore. The reuse of project plans is already prevalent within the oil and gas industry. A Per...

A gas kick simulation model for deep-water horizontal well with diesel-based drilling fluid is presented in this paper. This model is mainly based on the mass, momentum, and energy conservation equations. The unique aspect of this model is the fluid-gas coupling and the change of mud properties after the gas influx from the formation. The simulation results show that the gas in an annulus disso...

Automatic inspection of petroleum well drilling has became paramount in the last years, mainly because of the crucial importance of saving time and operations during the drilling process in order to avoid some problems, such as the collapse of the well borehole walls. In this paper, we extended another work by proposing a fast petroleum well drilling monitoring through a modified version of the...

Cost reduction is a driving force in the development of brownfield wells.1 It is well known that better planning leads to better execution in the drilling phase with less nonproductive time and reduced costs. This paper describes enhanced well planning workflows in light of recent software technological innovations. The technology, which enables this solution for the first time in the industry,...

Abstract This paper establishes the risk assessment index system according to characteristics of oil and gas drilling engineering cooperation project. After modularizing risk indexes of oil and gas drilling engineering cooperation project into eight clusters, risks are evaluated on the basis of multi-level fuzzy comprehensive evaluation method. The study is to construct risk assessment indexes ...

OBJECTIVES The purpose of this study was to evaluate the temperature change during low-speed drilling using infrared thermography. MATERIAL AND METHODS Pig ribs were used to provide cortical bone of a similar quality to human mandible. Heat production by three implant drill systems (two conventional drilling systems and one low-speed drilling system) was evaluated by measuring the bone temper...
