VIDL Network experience can introduce you to Gradiometry, or more specifically, gravity and acceleration. Gravity gradiometry is the study and measurement of variations in the acceleration due to gravity. The gravity gradient is the spatial rate of change of gravitational acceleration. Gravity gradiometry is used by oil and mineral prospectors to measure the density of the subsurface, effectively the rate of change of rock properties

The use of Full Tensor Gravity Gradiometry, or FTG, is becoming increasingly common in the exploration industry. This set of three modules and projects will allow you to become familiar with the dataset as it is used in oil, gas and mineral exploration, gain full background understanding of the components and how the data is acquired. Each module consists of three videos, a project and [...]
VIDL Network™ Project GR501 Full Tensor Gravity Gradiometry (FTG) Understanding the Components Modeled Geological Features Identifying Components in Modeled Data In VIDL Module GR102 we considered each of the components; from what you have heard in the video and read through the notes, identify which component is which in the following examples. As a reminder here is a summary of each component and an example [...]
VIDL Network™ Project GR502 Full Tensor Gravity Gradiometry (FTG) Understanding the Components Real Data As a reminder here is a summary of each component and an example of modelled data:In VIDL Module GR102 we considered each of the components; in the previous project you had the opportunity to become more familiar with recognising the components. In the following two examples we’ll work through a similar [...]
This module consists of a series of three (3) Videos and a summary text (PDF). All three videos are covering the topic Understanding the Components of Full Tensor Gravity Data. - Video 1 – What is FTG. We start with the basics by looking at what gravity is and the difference between conventional gravity and gravity gradiometry, then on to an overview of tensors and [...]
This module consists of a series of three (3) Videos and a summary text (PDF). All three videos are covering the topic Understanding the Components of Full Tensor Gravity Data. - Video 1 – Understanding the modeled response of a simple block. We start with understanding the characteristics of the tensor’s signal responses utilizing the modeled responses of a simple block as an example. [...]
This module consists of a series of three (3) Videos and a summary text (PDF). All three videos are covering the topic Survey Planning and Acquisition of Full Tensor Gravity Data. - Video 1 – Feasibility; is FTG valuable for this target? We consider determining if FTG is suitable for surveying the intended exploration objective. - Video 2 – Planning an FTG [...]
