  • Passive Seismic

    Passive seismic exploration methodology, in particular the IPSS/IPDS (Infrasonic Passive Seismic Spectroscopy/ Infrasonic Passive Differential Spectroscopy ) and PST/MST (Passive Seismic Tomography/Micro Seismic Tomography) technique uses spectroscopic and time analysis of the seismic background noise acquired passively using high sensitivity VBB (Very Broad Band) 3D seismometers.  Passive ...

  • Seismic Reflection Method

    Compiled and rigorously edited stacking velocity data to produce velocity maps at specified travel time intervals. These maps were verified to be extremely accurate, enabling exploration staff at AMOCO Production's Alaska North Slope group to make much needed time-depth conversions. Produced time-structure Maps via interpretation of Gulf Coast seismic reflection data while employed with Conoco, ...

  • An environmentally–friendly integrated seismic imaging for coal exploration in the Miocene Soma Basin, Western Turkey

    Seismic reflection data from target depths of several hundred metres have been acquired and processed as an aid for lignite exploration in the Miocene Soma Basin, western Turkey. An environmentally–friendly approach was followed by acquiring the data with mini–vibroseisseismic source along crooked lines, using available mountain/forest and village roads; quality control tests were conducted to ...

  • The use of shallow high resolution seismic reflection data to determine drilling locations at the Apache powder superfund site.

    INTRODUCTION Groundwater contamination at the Apache Powder Superfund Site in Cochise County, Arizona includes dissolved nitrate-N and perchlorate. Past studies have determined that these contaminants migrate laterally from a perched zone underlying Apache Nitrogen Products, Inc. operating areas into the shallow aquifer of the San Pedro River alluvium (shallow aquifer). The base of both the ...

  • Seismoelectric survey project for oil and gas exploration in Mangistau Oilfield, Kazakhstan - Case Study

    The seismoelectric survey was conducted by Seismo Electronics LLC in November, 2015. After our survey, seismoelectric data from measurement points nearby proposed location do not show promising hydrocarbon reservoir and their signal anomalies are even weaker compare to anomalies from two existed wells. We didn't recommend drilling in this proposed location, but our client is interested in a ...

  • Use of paleontological data in long–distance correlation between wells drilled for hydrocarbon exploration

    The purpose of this paper is to briefly review theory and applications of RASC and CASC. The latest versions of these computer programmes employ user–friendly graphic modules. Since 1978, these methods have been widely applied by major oil companies to correlate over long distances between wells drilled for hydrocarbon exploration. The purpose of ranking is to construct an optimum sequence ...

  • Donzi landfill expansion using stratagrid case study

    Background The Donzi Lane Landfill in Atlanta, GA had been in use since the 1970's for construction and demolition waste disposal. The site was nearing its capacity and additional landfill space was urgently needed due to the accelerating population growth and waste stream generated by development. Due to the high cost and long lead times for designing, permitting and constructing new ...
