AIG Instrumentos provides the key information you need during the design phase for the installation of pipes, plants, sub-stations and structures, giving you a view of the electrical parameters of soil through Soil Resistivity measurement. To know these values that result in corrosion levels, can save large sums of money on the installation of cathodic protection systems and grounding grids, ensuring that the metal structures installed have the estimated useful life.
The most common methods used in the oil industry and telecommunications are Wenner and Schlumberger. The study consists of inserting the 4 electrodes on the ground by placing them in a straight line, the separation between the electrodes will depend on the method used and such separations will allow to measure the resistivity values at different depths.
Soil Electrical Resistivity Test is also used to determine the existence of groundwater level for the installation of water extraction wells.
We have latest technology equipments, allowing measurements in a short time with very precise values of the renowned brand AEMC and highly trained personnel to perform these studies.
AIG Instrumentos supports its Marine Services in all development activities engineering in all water depths providing “high-resolution characterization of layers of the seabed” in order to reduce risk, facilitate ways and designs putting their available information you need to know, offering a quality service on time.
Through studies of marine seismic provide stratigraphic information sub-soil and structural geology using the principle of reflection waves to image the subsurface, recipients of these waves are hydrophones that are installed on a cable that is maintained at a certain depth .
The depth of the study will depend on the requirements of projects and soil characteristics, can offer different sources to adapt to the needs of our customers: Boomers, air guns, sparkers, among others.
We have high-tech equipment for seismic acquisition in order to obtain the best possible results. In addition, we have experts in the area of acquisition, processing and seismic interpretation.
We also offer Sub Bottom Profiler (SBP), which can be used coupled with marine seismic or independently for better resolution of the shallow layers and Side Scan Sonar (SSS) for obtaining a true picture of the seabed which allows a real image of the seabed and is used to locate and map sandbars and rocky outcrops , locate man-made , such as archaeological sites, sunken machinery and detect objects on a small scale , such as anchors, propellers, underwater pipelines objects , etc. Another study used to complete information is Magnetometry to detect metal elements on the surface or buried
In those hard to reach places such as rivers and seas where it is essential to have information from the depths of the bed and the bottom morphology to design and make way for the next phases of the project, AIG Instrumentos is present offering “High precision depth and morphology of the seabed “.
During the study bathymetric, measuring the depths it is achieved by devices that emit sound waves. These emitted waves travel through the water, to meet the seabed are reflected and then travel back to the surface, thereby obtaining depth.
We offer studies using single beam bathymetric and multibeam, team selection will depend on customer requirements and the study area. In the case of using single beam echo sounder, moving the boat you have the bathymetry of a line while the multibeam echosounder bathymetry of an area is obtained, the latter is ideal for deep areas. We also offer positioning system WASSS or C -NAV depending on the required accuracy.
Like the marine seismic, we can complement these studies bathymetry with Side Scan Sonar (Side Scan Sonar) to have a picture of the seabed, allowing locate and map sandbars and rocky outcrops, locate man-made objects, as archaeological sites, sunken machinery and detect objects on a small scale, such as anchors, propellers, underwater pipelines, among others, also can accompany the study Magnetometry to detect metal elements on the surface or buried.
