Ground electromagnetic profiling, using a Geonics EM34-3 instrument, has been employed to identify areas of high conductivity in a Precambrian basement complex terrain of Nigeria. Field examples, conducted as part of a rural water supply programme, are presented. They indicate that the apparent conductivities are generally lower than about 60 mmho m−1. Subsequent borehole drilling suggests a good correlation between high EM34 anomalies, deep weathering and high well yield (> 1 1 s−1). On the other hand, boreholes sited on conductivity lows penetrated a thinner regolith with relatively lower yields.

Actual Stress

Abstract This paper describes a method of experimentally ascertaining the actual stress-time curve in a mechanical part subjected to an impact blow. The apparatus consists of a resistance strain gage in conjunction with a high-speed recording oscillograph, the combination being sufficiently rapid in response to record strain variations occurring within a few microseconds. Consequently, the strains during impact are recorded with sufficient accuracy for detailed analysis. Longitudinal strain waves in long bars striking end to end have been subjected to theoretical analysis and have served as a subject for testing of the apparatus. The theory is reviewed in this paper, and computed results based thereon are compared with experimental data. The agreement is shown to be satisfactory, the form being as predicted and the magnitude within a few per cent of the computed value. The strain waves and reflections occurring in this simple case are surprisingly complex. An investigation of other impact problems by this method, such as the correlation of standard impact tests of materials, might well yield information of considerable value.

Groundwater Demand

ABSTRACT Stable O and H isotope data distinguish three sources for base flow in five reaches of the San Pedro River: (A) base flow and sub-flow from upstream reaches of the river; (B) bank storage derived from summer monsoon floodwater; and (C) water from the mountainous flanks of the river catchment. A and C support base flow in the sub-basin upstream of Sierra Vista. A, B, and C combine to support base flow near St. David. Source C in this area is ancient deep-basin groundwater. Source C dominates in Cascabel near Benson Narrows, with downstream additions from A. In Cascabel near Gamez Road, sources A and C combined to support base flow that had disappeared by 2019. Near Redington, source C appears to have operated through a limestone aquifer vulnerable to short-term drought. Groundwater sub-basins separated by impermeable sills in the riverbed are evolving into hydrologically separate sub-basins as base flow across the sills decreases. The decrease in base flow partly reflects regional long-term drought, which has been exacerbated by pumping. Additional groundwater demand from urban growth upstream of Benson is likely to cause further decline of base flow near St. David and Sierra Vista.

Hydrodynamic Study

Bottomhole formation zone processing (BFZP) is performed at all phases of oil field development to restore and improve the filtration-capacity properties of the bottomhole formation zone to improve the oil yield. The choice of the BFZP technology is made basing on the study of the reasons for low well yield with account for the collector properties of productive sediments and rheological characteristics of the formation fluids, as well as a special geologic-geophysical and development-hydrodynamic study for the assessment of the porosity and permeability properties of BFZ. The research objective is to develop the criteria and assess the conditions for the application of bottomhole formation zone processing technologies for the upper Jurassic formations. Analysis of the results of laboratory and industrial research allowed offering the most efficient technologies for the influence on the upper Jurassic deposits.
