Field-scale monitoring of a horizontal ground source heat system

Geothermics, 2016
The performance and sustainability of ground source heat systems is dependent on the thermal behaviour of the neighbouring ground. This paper presents a field-scale monitoring scheme which has been designed and implemented to inspect the ground behaviour in response to a horizontal ground source heat system providing space heating to a domestic ...

Monitoring and evaluating the volume fracturing effect of horizontal well

Journal of Natural Gas Science and Engineering, 2015
Abstract The volume fracturing technology has been the key technology to develop extra-low permeability, ultra-low permeability, and even the tight oil and gas reservoirs. Based on the real case of a volume fracturing horizontal well in Jilin Oilfield, the microseismic (MS) technology was used to monitor the effect of volume fracturing, and the MS ...

Automatic monitoring of horizontal displacement in deep foundation pit

2012 International Conference on Systems and Informatics (ICSAI2012), 2012
This paper aims to introduce the free stationing and its accuracy analysis in horizontal displacement monitoring of deep foundation fit, as well as discuss the feasibility and efficiency of using free stationing to maintain a horizontal displacement automatic monitoring, which is based on the automatic deformation monitoring of Georobot.

Monitoring and modeling horizontal gene transfer

Nature Biotechnology, 2004
Monitoring efforts have failed to identify horizontal gene transfer (HGT) events occurring from transgenic plants into bacterial communities in soil or intestinal environments. The lack of such observations is frequently cited in biosafety literature and by regulatory risk assessment.

Horizontal Monitoring in the Netherlands: At the Crossroads

Bulletin for International Taxation, 2013
Due to the prolonged economic downturn, tax compliance regarding large businesses is currently under scrutiny worldwide as never before. The key question is what are and will be the effects of the pressure to generate more revenue on new developments, such as horizontal monitoring.

A shear-horizontal SAW device as a pH monitor

Sensors and Actuators B: Chemical, 1993
Abstract A shear horizontal surface acoustic were (SAW) that propagates on 36° rot. Y-cut X-propagating LiTaO3 immersed in a liquid is affected by an acoustoelectric interaction between the piezoelectric potential and the electrical properties of the materials in the liquid.

Horizontal&Vertical Deflection Combinations for Monitors

IEEE Transactions on Consumer Electronics, 1985
Many of the integrated circuits for deflection utilized in monitors and video displays are TV application oriented. However, the monitor market is becoming more and more important, sufficiently so to justify the development of integrated circuits specifically aimed at satisfying the specific requirements of this field.

Dual Treatment Monitoring with a Horizontal Receiver Array

Proceedings, 2009
Microseismic monitoring from a horizontal well poses some challenges in terms of accurately determining the depth of the microseismic events. To handle data recorded by receivers distributed generally in deviated or horizontal wells, the full polarization vector in addition to event times must be included in the location algorithm.
