Reduce drilling time and cost. Avoid the cost of lost fluid and circulation

The margins in land, offshore and deepwater drilling operations are tighter than ever before, which means that any unplanned fluid losses – and the associated NPT – can significantly impact on your well’s economic performance.

The risk of lost circulation is present most wells, and increases in weak and fractured formation, or when exploring new reservoirs beneath depleted zones. At these greater depths, hydrocarbon sources are found within complex geologic structures.

As drilling complexity increases, the need for an effective wellbore strengthening strategy to prevent and cure lost circulation increases too. Wellbore strengthening strategies minimize the likelihood of lost circulation by strengthening the wellbore and arresting fracture growth. The result is an increased tolerance of higher downhole pressures under drilling and cementing conditions.

Wellbore strengthening strategies engineered to prevent fluid loss

Before developing a wellbore strengthening strategy engineered to prevent fluids and lost circulation – our fluids specialists take the time to understand your drilling plan and formation. After carefully selecting from Newpark proprietary mechanical wellbore stabilization products, a solution is engineered to address modeled loss rate severities and fracture geometries. Additionally, we anticipate potential issues to ensure that back-up options are available to remediate unexpected fluid loss challenges encountered during drilling.

The most effective wellbore strengthening strategy is to run products for the entire section to seal fractures soon as they begin to form thus preventing induced fractures from growing. Using wellbore strengthening materials in sweeps or dedicated pills is recommended only when downhole tools prevent whole fluid treatments.

Prevent and quickly fix fluid losses in induced and naturally fractured reservoirs

With Newpark FIX™ wellbore strengthening additives, you can drill exposed, weak formations or depleted zones with confidence and more cost certainty. All thanks to the engineered preventative wellbore strengthening and remedial fluid loss properties of this innovative solution.

Newpark specialists model predicted fracture width and loss rate to recommend the appropriate wellbore strengthening and loss prevention strategy. Either by deploying individually or a combination of single-sack FIX additives.

PreFIX™ preventive seepage control blend is comprised of soft, compressible materials designed with an engineered particle size distribution. PreFIX™ provides excellent pressure isolation and protects the fracture tip.
