a r t i c l e i n f o The use of high-volume horizontal hydraulic fracturing (fracking) has increased substantially over the past five years in the United States. Use of this drilling technology to extract natural gas from hitherto impermeable shale is expected to increase even more in coming decades. Two institutions, integration contracts and well spacing requirements, evolved to mitigate the...

Laser drilling is a well-established process in aerospace industry. However quality and geometry of holes do not get under control in an absolute way. Moreover, drilling understanding is complicated due to the number of parameters and physical phenomena. Laser and matter have some own parameters which are not constant with temperature, and so could not be fitted. In this paper, we describe the ...

With the introduction of nanotechnology, energy industries envisage a potential revolutionary change in the field of exploration, development and production. Research by universities into such areas as nanosensors, nanomarkers and nanobots to provide valuable data regarding the reservoir are of great focus due to their large potential return on investment, but have yet to yield substantive prod...

Oil well drilling operation is a complex process, in which there are always new lessons learned during drilling operation. Casebased reasoning (CBR) is an approach to problem solving that recalls previous experiences. Whenever the process is running smoothly, or is failing, the experiences gained during such episodes are valuable and should be stored for later re-use. This paper presents a meth...

Situation Awareness (SA) issues are often identified as contributing factors to drilling incidents, most recently in the Deepwater Horizon blowout. Two studies aimed to identify the cognitive components required for offshore drillers to develop and maintain SA whilst controlling subsea hydrocarbon wells. In study one, critical incident interviews were conducted with 18 experienced drilling pers...

The data measured by well bottom sensors can be transmitted to the surface through the drilling mud during oil drilling operations. This article introduces a data processing scheme for a wireless data transmission application via mud. The detailed signal processing procedure is given, and several data processing techniques used are discussed, mainly including data encoding and signal integratin...

Achieving minimum cost and time in reservoir drilling requires evaluating the effects of the drilling parameters on the penetration rate and constructing a drilling rate estimator model. Several drilling rate models have been presented using the drilling parameters. Among these, the Bourgoyne and Young (BY) model is widely utilized in order to estimate the penetration rate. This model relates s...

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...
