Lost Circulation Materials
Targeted Treatments for Every Loss Type
Lost circulation refers to the partial or complete loss of drilling fluid into formation. It can stem from naturally occurring geological conditions or improper pressure management. As a common and potentially costly drilling hazard, ineffective mitigation can jeopardize well stability, damage formations, and lead to significant nonproductive time (NPT)—up to and including well abandonment.
Our lost circulation materials portfolio delivers reliable solutions across the full range of loss challenges. WEL‑Sure™ Self‑Degradable Lost Circulation Material (LCM) provides reservoir‑safe loss control for severe conditions by sealing fractures and then degrading over time to protect long‑term productivity. For total losses in fractured or highly permeable formations, the LCM 115–116 Polymer System delivers deep placement and robust shutoff by reducing permeability at the source. Complementing these solutions, WEL‑Stabilizer™ Lost Circulation Material offers fast‑acting wellbore stabilization by sealing microfractures and limiting fluid invasion, helping operators drill ahead with confidence in unstable formations.
