Advantages and disadvantages of mechanical structures that are implemented in specific equipment. We present experimental design, developed and passed posters and well tests in "NIImorgeofizika-Interservice."A.D. ChigreenE.A.VinogradovV.A.Demakin...
Image data from these tools are used for a wide variety of tasks, including fracture studies, hydrofracture stress measurement, assessment of borehole breakout, casing inspection, and stratigraphy. Each group of tools has its advantages and disadvantages and will be described separately before any ...
After a brief introduction of both methods and their interpretation, a comparison between them is presented regarding their advantages and disadvantages using the results of the performed tests, which revealed an 8% difference in the soil thermal conductivity values, averaged over the length of the ...
To evaluate the new method and to identify advantages and disadvantages, several tests have been carried out, in the laboratory and in multiple groundwater monitoring wells in the field. Reproducibility of the PIB method was assessed through repeated tests, on the basis of the temporal development...
Three classes of blockage removal technologies for treating near borehole zones of oil production wells,presently used and under study,are reviewed on the basis of 17 papers published(besides of microbiological ones as the 4th class);their principles,advantages and disadvantages,and uses are presented...
The disadvantages of the prior art are overcome by means of the subject invention which comprises a method for estimating formation in-situ stress magnitudes using a sonic borehole tool. The method comprises generating a relatively low frequency signal and a relatively high frequency signal then dete...
Typically, these scintillation materials exhibit advantages over NaI(Tl) in some areas, but exhibit disadvantages in other areas. On such material is bismuth germinate (BGO), with properties well documented in the literature. The scintillation material cerium activated yttrium aluminum perovskite or ...
In the offered work the technology of the drill excavation for heat pumps is elaborated and the system of monitoring parameters of drill mode suggested either. In the first part a principle, advantages and disadvantages of heat pumps are explained and then a description of used technologies and ...
Advantages, disadvantages, and drilling adaptability of several rigs earlier used in domestic coal mine are analyzed. CMS 1-800/30 crawler jumbo is reconstructed from standing pillar rig according to specific condition of long bedding borehole at coal face which possesses rockburst trend. Wide blade...
We calculated and analyzed the potential characteristic curves of three different types of borehole configurations, as well as quantitatively evaluated their depth. The model test is made to invert and contrast the information gathered by various gadgets. The advantages and disadvantages of various bore...
