Survey Georadar (Ground Penetrating Radar)

Ground Penetrating Radar (GPR) is one of the methods in geophysics that uses an electromagnetic wave source in the form of radar. GPR works by utilizing the reflection of radar signals that are transmitted into the soil layer. The signal will be reflected when there is a dielectric constant difference in the soil layer. So we get the results of subsurface images (radargram) with a certain level of depth from the results of the reflection of the radar signal received by the tool.

Survey Pipeline Oil and Gas

Radio Frequency Location (RFL) is one of the methods used to detect the presence of paths and depths of a metal-based utility network (pipes and cables) that are embedded below the surface of the ground by utilizing electromagnetic wave propagation (EM). The use of the Radio Frequency Location method with the Pipe and Cable Locator tool uses 2 (two) tools, namely Transmitter (Tx) and Receiver (Rx). The function of the Transmitter (Tx) is to emit frequencies, and Receiver (Rx) to capture frequencies.

Survey Geoelectrical

Geoelectric is one of the geophysical methods that produce electricity on the earth and how to detect it on the surface. By utilizing the propagation of an electric current, a potential difference value is obtained so the difference in resistivity values below the surface can be known. The geoelectric method can be used for groundwater investigations, soil structure, mineral exploration and archeology and can be used to determine the potential for soil movement. Geoelectric analysis based on different materials will have different resistivity values flowed by electric current.

Horizontal Directional Drilling

Horizontal Directional Drilling is one of the trenchless methods for installing subsurface utilities. Utilities that can be installed with this method such as clean water pipes, sewage pipes, oil/gas pipes, power cables, fiber optics, and others. HDD can be used to create underground lines that cross rivers, roads, and existing structures, so that utility lines can be built through them. Compared to digging the ground to install pipelines, horizontal directional drilling technology has installation costs 6-8 times lower.

Topography Mapping Survey

A Topographic Survey is a survey that gathers data about the elevation of points on a piece of land and presents them as contour lines on a plot. The purpose of a topographic survey is to collect survey data about the natural and man-made features of the land, as well as its elevations. Output of Topograpy Survey is Topographic Maps that use the elevation.
contour lines to show the shape of the Earth's surface. Elevation contours are imaginary lines connecting points having the same elevation on the surface of the land above or below a reference surface, which is usually mean sea level. Contours make it possible to show the height and shape of mountains, the depths of the ocean bottom, and the steepness of slopes.

Manual Drilling

Manual Drilling

Manual Drilling is a method of creating horizontal holes using simple tools (not machines) by piercing through until reaching the end of the path. The tools used can include a 2-inch PVC pipe, with the end of the PVC pipe equipped with a sharpened galvanized iron, and water is used to soften the soil being bored. The excavation size is 1 meter long and 0.5 meters wide. The distance between one excavation hole and the next (span) is approximately 6 to 8 meters.

Pipeline Installation

Pipeline Installation

Pipeline installation is the process of installing a piping system used to transport various types of fluids (liquids or gases) from one place to another. This process involves several key stages, from planning and material selection to testing and completion. Piping systems are crucial in various industries such as oil and gas, water, chemicals, and construction. Pipeline installation requires technical expertise and careful planning to ensure the system operates effectively and safely. Good collaboration between planners, technicians, and field workers is essential for the success of a pipeline installation project.
