OIL & GAS EXPLORATION
HELPING OUR CLIENTS GET THE MOST SOURCE POINTS, WHILE MITIGATING RISK.
IGS helps clients get the most source points with the maximum amount of seismic energy in the ground, without causing damage to surrounding structures.
At IGS we don't use distance as a pre-requisite, we conduct site attenuation studies which allow us to use the rate of decay of the vibration waves to accurately predict the PPV at the closest structures. Often our clients can work closer to structures, allowing for more source points, which gives a better resolution of substructures.
With on-site monitoring that moves as the project progresses, our qualified technicians monitor vibration for damage claims and liability.
Experienced IGS technicians monitor shot hole and vibroseis activity. All field technicians are equipped with multiple vibration monitors, a GPS unit and range finder. Data is recorded on a tablet in the field for a paperless recording and reporting system. Monitoring data is then presented in a spreadsheet and plotted on Google Earth. For documentation, photographs of the setup and background of each monitoring unit is taken.
Site attenuation studies are a scientific regression analysis that show the decay rate of vibration energy. They allow us to make appropriate recommendations on stand-off distances and get closer to structures while staying within limits.
IGS conducts pre- and post-condition inspection to document the visible condition of structures prior to and after source points have been shaken or shot. These provide vital evidence in the event claims arise.
IGS works with pipeline companies, refineries, cities and government agencies to negotiate stand-off distances and increase allowable PPV values, using scientific analyses. We can also recommended specific vibration criteria.
IGS will view and discuss the alleged damages. They are photographed then compared to the seismic data and vibration criteria. At the end, an opinion is rendered on whether damages were caused by or attributed to the seismic activity.
IGS conducts third party chemical analyses on well water sample and ultra-sonic flow rate testing - a completely non invasive testing method. Tests conducted include; minerals, hardness, alkalinity, suspended solids, pH, etc.
Road inspections document the conditions of a road before and after vibroseis trucks have vibrated the street. Reports include geo-referenced video with mapped locations of where the video is on the screen.
