Unwanted water production can erode well performance and asset economics if left unmanaged. Interwell’s precision water shutoff approach, grounded in diagnostics and engineered isolation, helps operators identify water-entry points, protect hydrocarbon flow, and restore sustainable well performance in mature and complex wells.

The oil industry has responded rapidly to the decline in oil prices of these last few months. -
Today, there is a need for higher-strength coiled-tubing (CT) grades with better resistance to severe environments and better fatigue performance in both the tube body and the bias weld.
-
Microbial-influenced corrosion (MIC) has been implicated in few corrosion-related challenges in the well-service industry in the past.

The technical contributions highlighted this year focus on matrix stimulation of carbonate and unconventional reservoirs.
-
Core-flow tests are usually conducted to test and model stimulation treatments at laboratory scale, to predict the performance of such treatments in carbonate reservoirs.
-
Mechanical-diversion techniques can ensure acid injection into the various intervals of naturally fractured reservoirs.
-
An operator developing tight carbonate reservoirs found that conventional acid stimulation with 15% hydrochloric acid (HCl) in horizontal wells did not provide expected results.
-
When it comes to fracturing, experts argue about many things, but they agree that fractures do not look like lightning bolts, tree roots, or shattered glass.
