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 circulation challenges. WEL-Stabilizer™ Lost Circulation Material is a versatile, fast‑acting solution designed to reduce fluid invasion across a wide range of loss scenarios, helping operators maintain circulation and drill ahead with confidence. For total losses in fractured or highly permeable formations, the LCM 115 Cross-Linking Polymer System delivers permanent solution with deep placement and robust shutoff by reducing permeability at the source. WEL‑Sure™ Self‑Degradable Lost Circulation Material provides reservoir‑safe loss control for severe conditions by sealing fractures and then degrading in a controlled time frame to protect long‑term productivity.
