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.

Monitoring of Landfill Settlement by Means of Horizontal Inclinometers

2010
Waste settlement will affect the liner system and ultimate usage of the municipal solid waste landfill significantly. Settlement at different depths of a landfill cell in Shanghai Laogang Landfill, China, is monitored by means of horizontal inclinometers.

Monitoring horizontal motions in a local network at Caneva in Friuli, Italy

Journal of Geodynamics, 1993
Abstract The intention of the “Caneva network” is the detection of tectonic movements in the area. It consists of 11 points and has a dimension of about 700 × 2200 m. The point positions are chosen by topographical necessities. The first epoch was observed in 1985, the others followed in annual intervals—up to now there have been eight epochs ...
