Igneous, Volcanic Rock $3,000.00

Well Log Analysis of Volcanic Rocks: Examples from the Nevada Test Site, Nye County, Nevada As the exploration for hydrocarbon resources continues to move into non-traditional areas, and as the search for additional energy resources such as geothermal continues, subsurface geologists will encounter rocks not usually found in typical sedimentary-basin settings. One such group of rocks rarely encountered by most subsurface geologists is volcanic rocks. Volcanic rocks, however, are common at and near the surface in many parts of the world. Volcanic rocks have a variety of litho-facies with significantly different fluid-flow properties. The accurate characterization of volcanic litho-facies is critical in evaluating the potential of volcanic deposits for energy resource exploitation. As with sedimentary rocks, well logs provide valuable data for analyzing the various volcanic litho-facies encountered in drill holes. However, unique aspects of the composition, deposition, and alteration of volcanic rocks require a certain amount of special knowledge about volcanic rocks and their responses to various well logs in order to accurately evaluate and characterize volcanic litho-facies. At the Nevada Test Site (NTS) in southern Nye County, Nevada, more than 4,000 holes have been drilled as part of the underground nuclear weapons testing program and subsequent environmental restoration and groundwater modeling activities. Because the NTS lies within the southwestern Nevada volcanic field, many of the holes have encountered volcanic rocks, resulting in a large amount of well log data from volcanic rocks, and extensive experience in the subsurface characterization of volcanic litho-facies. Presented here are examples of well logs from a variety of volcanic litho-facies.

What Makes Our Process More Accurate

LogDigi technology completely adopts relative concepts and rebuilds a strict lithologic conductive equation. LogDigi technology is significantly improved well log analysis technology and different from current well-logging interpretation methods that use absolute concepts.

Traditional technologies are all based on an approximate value in the designing of well-logging equipment, result measurements, data collection and data processing. When facing extremely complex lithology, it is necessary to design models in each area based on changes in objective conditions. Traditional technology does not adapt based on changes of objective conditions. Traditional technology is often affected by different lithological, regional, and well conditions. Traditional technology cannot accurately locate oil and gas zones with complex lithology.

LogDigi technology has changed the current technology model of evaluating quantitative oil/gas formations. This technology is a breakthrough in well-logging technology, and an innovative method for the discovery of new oil and gas zones. LogDigi technology can automatically remove the influences of lithology variations in different areas and different depths. It can also compensate complex conditions, such as influences of deep intrusion of mud filtrate in drilling with saline mud. LogDigi method also evaluates the influences of oil layer flood out and automatically finds out whether or not the parameters are accordant with actual situations. This allows us to locate oil and gas zones 90% and greater. log evalution for porosity, saturation, effective thickness of reservoir beds. This plot is one of the successful samples.  Contact us for detail.

90% old oil wells do not have Nuclear and Sonic logging. For many oil companies, in order to re-exame their oil fields, they have to sent down sophisticated nuclear, and acoustic tools on a wire-line for the well. It costs them a lot to do that.

  • We re-evalute your oil fields with your existing logs. We do not need "many times costly core sample taken from the well", and "sophisticated nuclear, and acoustic tools are sent down the well on a wire-line". What we need just gamma ray (or SP),and resistivity. We can match your budget to re-evaluate your oil fields.
  • We determine the fluid and pressure distributions throughout the reservoir, the natural energy sources available, and the methods most useful in recovering the maximum amount of oil or gas from the reservoir.
  • We analyze, interpret, and optimize the performance of individual wells. We decides if it is economically feasible to make the investment needed to produce the well. If it is, the production engineer is given the tasks to determined how to bring this valuable fluid to the surface.
  • We analyze data to locate drilling sites where oil and gas may have accumulated in commercial quantities.
