One of the biggest complaints we hear from our oil and gas clients is about inconsistent survey data. On the one hand, they’re spending thousands of dollars on surface engineering data, and the cost is justified because of its business value. That data saves money down the line. Except it doesn’t. Because when drilling, completions and facilities engineers get the data, they often can’t trust it.
It’s data that comes from GPS and theodolite surveys, as-built drawings, and from other sources that aren’t always even identified. Any given data point could have come from any of these sources. Frequently the engineering data is not reliable enough.
What’s needed is a data set that comes from one, reliable source. Then existing data sets can be compared against that. Instead of several differing views, there’s one authoritative, reconciled picture of what’s happening on the ground.
PhotoSat offers our oil and gas clients coherent project location data with elevation accuracies better than 20cm. Completions, facilities and drilling engineers can work from a reliable data set now and in future project stages.
The value of surface engineering data is directly proportional to accuracy. We help our clients maximize the value of their engineering data by providing reliable data across the project site. That data can be used to inform cut and fill volume estimates as well as to streamline facilities engineering projects and well pad selection.
Additionally, surveying via satellite means less boots on the ground. Fewer survey teams have to work in hazardous working environments and less expensive equipment is exposed to the risk of damage at the project site. Data is also available in a usable form far more quickly, typically within five days.
So how does it work?
We start with the data set our client already has. Then we compare it against our own topographic survey. When we find inconsistencies, we work with the client’s project team to select the appropriate reference data set for that inconsistency, and shift the others horizontally and vertically to match it. This process usually means we’re leaving our clients with datasets that match to within 10cm vertically and 25cm horizontally. Clients also get a matching 1m grid of our satellite engineering topography, accurate to 20cm in elevation, and a 50cm precision satellite ortho photo with 25cm horizontal accuracy. That provides a reliable basis for future data-dependent engineering projects like surface design work, including cut and fill volume estimates.
We’ve delivered over 500 projects like this to clients all over the globe, and our clients know that there’s no better, faster or more accurate way to base their engineering data on something reliable and accurate.
