Infill Well Optimization
Maximize the returns from your infill well investments by harnessing the power of fit-for-purpose technologies and digital workflows
Infill drilling accounts for more than 60% of the new wells drilled in North America, making it more important than ever to follow a consistent and holistic process of planning, designing, constructing, completing, and producing them.
Infill drilling sparks changes for operators
In most US unconventional basins, operators start development by drilling the minimum number of wells needed to hold their acreage. These initial wells are sometimes called parent wells. Operators then start drilling infill wells, also called child wells. When the child well stimulation operation communicates with a parent well, the result is parent-child well interference or a frac hit.
Frac hits can have positive, negative, or neutral effects on parent well production. In addition, infill well production varies with distance from the parent, time elapsed since the parent began producing, and other factors. Rapid production declines can also occur in parent and child wells after infill well stimulation.

Learn about minimizing losses during well shut-in and restart operations.
Download the webinarParent production affects child fractures—and productivity
The point of infill drilling is to replace reserves as parent well production declines. But the parent well’s production depletes the reservoir, and the reduced reservoir pressure tends to reduce formation stresses, attracting new hydraulic fractures from nearby infill wells.
If a new well is too close to the parent well, its fractures will grow asymmetrically toward the lower stress, creating a drainage area that largely overlaps the area already depleted by the parent well. Thus, the child well’s initial production will be markedly lower than that of the parent well, and it will decline faster.
Differences in experiences by play exacerbate the challenge of optimizing the field and individual well designs.
