Are you looking to map the physical characteristics of a new area, or do you need quick answers about what’s in an area where you’re already active? Seisland employs highly-skilled field mappers who can access virtually any terrain and use industry-leading technology to create high-quality field culture maps for seismic surveys, construction, as well as power-line and underground utility locating. From the moment the crews arrive on-site to map delivery, we are fully digitized – including offering an industry-leading online access service, TriliGIS.
The goals of seismic surveying and field mapping are to position and plot the locations of the receiver stations (geophones) and source points, plus all other important features and hazards such as pipelines and power-lines, fences and gates, roads and trails, properties, buildings, wells and water sources. The work includes identifying exclusion zones – areas where source and receiver points are not permitted – such as water bodies or close proximity to pipelines.
Seisland’s approach to field mapping is to create the hazard assessment and field culture map first! We never try to make our surveyors map while they survey. Why? Because having a map already in hand is safer and more efficient for the surveyors. It helps prevent trespassing. And it gives you, the client, more control over redesigning your seismic program at the field level.
Think about this: by identifying and mapping hazards, exclusion zones (where source and receiver points are not permitted) and field culture first, our surveyors aren’t just moving these points based on general skidding guidelines in complicated areas. Rather, our mapping team will have identified them ahead of time, with appropriate exclusion zones mapped so that you, the client, can remodel these points and select optimal locations. The survey team will then have their tasks properly defined, removing a source of miscommunication about the job to be done.
Seisland’s numerous surveys, stretching over many years, have demonstrated that mapping first is effective and efficient for the client and the survey contractor. Among other benefits, it can reduce the remodelling time, thus greatly reducing remodelling charges. Ultimately, the client has more control over source and receiver point locations and, therefore, will end up with a superior final product.
