Build Subsurface Models with TVD and Petrophysical Data

Rosemary Jackson
TVD is a common data type that has the power to capture intricate subsurface features. True Vertical Depth, or TVD, is a measure of how vertically deep a point of a well is from the Kelly Bushing elevation reference point, can be predictive of some things that you’re looking for like production.

Geomechanics and the Complex Reservoir

"It’s important for us to have a systematic way to break things down into different buckets where we use the Petro.ai Drilling Spacing Unit Design Service to analyze section by section. The three major systems are geology and subsurface which includes geomechanics, the engineering aspects, and the economic aspects of the development of a DSU.

Offset Well Complexity: The DSU Design Service Tradeoff Approach

All uncomplicated DSUs are probably the same, but all complicated DSUs are complicated in different ways.

Frac Growth and Well Spacing

Frac Growth and Well Spacing

Most of the companies we work with are developing multi pay zones,” Kyle LaMotta, VP of Analytics explains. “The traditional thought is to establish what the well spacing is and geometrically space all the wells the same. But the stress is varying with depth so in one zone the fracs might go up more than in another zone where they might go out more. In that situation you’d want to consider different well spacings for different targets.

The Influence of Perf Erosion on Stage Optimization

The Influence of Perf Erosion on Stage Optimization

“Perf erosion is going to be a good indicator of perf efficiency,” Kyle LaMotta, VP of Analytics explains, “It’s an indication of whether you’re placing proppant in the perforation. If you don’t see any perf erosion that means you probably didn’t put any proppant in those particular perfs. We’re able to predict that."

Offset Drainage Calculated for DSU Parent/Child Interactions

Offset Drainage Calculated for DSU Parent/Child Interactions

We’re worried about the offset drainage; how do I bring that into our Drilling Spacing Unit (DSU) analysis? The ultimate effect of parent wells on infill child wells is hard for companies to examine because they lack a direct way of figuring out what that spacing needs to be.

Can the Petro.ai Drilling Spacing Unit Design Service take asymmetry into account?

Can the Petro.ai Drilling Spacing Unit Design Service take asymmetry into account?

“Asymmetry comes up frequently with our clients,” Dr. Brendon Hall, VP of Geoscience at Petro.ai shares in a recent conversation about new value adds to the Drilling Spacing Unit (DSU) Design Service. “There are several types of asymmetries on a DSU. A first might be when you drill a pad there are some wells on the inside or interior of a pad and there are wells on the outside. There’s an asymmetry there.
