radioactive prospecting
Introduction
Radiological exploration is a technique used to analyze and assess the composition of soils and bedrock underlying the surface. It is a non-destructive method that can be used to identify the hydrological, geological and geophysical characteristics of the subsurface. There are variou......
microgravity exploration
In exploration and drilling for oil, microgravity surveys are used to map subtle regional density variations that can be related to oil and gas reservoirs. The technique is based on accurately measuring tiny variations in the gravity field of an area of interest. By analyzing the gravity field dat......
shallow refracted wave method
Introduction
Shallow refraction wave measurement is a geophysical method used to measure seismic velocity of subsurface layers. Originally developed in the 1920s, the method involves the use of a seismic source to generate a localized wave that is refracted when it reaches an interface between tw......
Expansive soil foundation survey
Introduction
Land base exploration is the process of investigation and collecting information about land, its environment, the materials it is composed of and the methods used in development. It is used to gain knowledge on how to best utilize the land for various purposes, such as for constructi......
Industrial Site Survey
Industrial Site Investigation
Industrial sites, large or small, have a complex of characteristics which requires careful examination, study and analysis in order to properly judge their suitability or potential suitability for use. Industrial site investigations are undertaken by a range of indiv......
very low frequency electromagnetic method
Very Low Frequency Electromagnetic Method
Very low frequency (VLF) electromagnetic methods are used primarily for surface and near-surface investigations of known conductive targets such as mines, pipelines, caves, and shipwrecks. VLF-EM instruments send low-frequency signals to the ground which ......
Engineering Seismic Exploration
Engineering Seismic Exploration
Engineering seismic exploration is a technique used when looking for petroleum, gas and other materials below the surface of the earth. In this process, shock waves are sent into the ground and seismic reflections, or echoes, are detected and studied. This can help......
ground radar method
Geophysical Radar
Geophysical radar methods are used to explore and monitor the subsurface of the earth in order to locate reserves of oil, gas, minerals, and other valuable resources. Geophysical radars use electromagnetic waves from portable or fixed sources to detect changes in the electrical c......
Magnetic Prospecting
Introduction
Magnetometer Surveying is a method of geophysical exploration that is used to measure the magnitude, direction and gradient of the magnetic field at a survey location. A magnetometer survey can be used to determine the type and location of magnetic anomalies that could be associated ......
