TenEx develops NoHit tech for shale well issues

By TenEx Technologies | January 13, 2020

As US shale wells fall short of production projections by 15 percent to 40 percent, exploration and production companies are drilling more wells on their acreage to compensate. These new “child” wells, drilled in close proximity to an existing “parent” well, can damage the parent and themselves be less productive than prior wells. The parent-child interference happens because the parent wells create a pressure sink in their production zone, encouraging child fractures to propagate to depleted rock instead of virgin rock.

In some of the most productive basins, most drilling in 2020 will be child wells. This will bring a higher cost per barrel for the child well and a weaker new decline curve for the parent well. Lease depreciation will likely result, affecting the borrowing capacity of E&Ps and their ability to drill new wells, according to TenEx Technologies.

In response, TenEx Technologies has developed a trademarked NoHIT, a patent-pending frac hit mitigation chemical technology which is the first of its kind in the industry. NoHIT is pumped as an additive to a parent well’s preload and/or active loading program, to temporarily pressurize the depleted rock and increase its associated rock stress.

“NoHIT represents an important tool for operators as US shale drilling enters a new phase in which a lot of the prime acreage is becoming saturated with wells. NoHit should extend the life of existing acreage by allowing infill wells to produce more oil and cause less damage to surrounding wells,” says Eric Foster, CEO of TenEx Technologies.

By pressurizing the depleted rock around the parent, NoHIT discourages child fractures from communicating with the parent fractures, thereby protecting the parent, and it encourages those fractures to target new reservoir. This helps the child well achieve its modeled production.

Using NoHIT, E&Ps can gain additional production from their acreage and reduce their cost per barrel.
