Severe-Duty Components for Oilfield Evaluation

Severe Duty Ceramic Sleeve Liner


CoorsTek has partnered and developed ceramic sleeves to encapsulate wireline and LMWD electronic technology that is resistant to high temperatures and pressures. These ceramic sleeves can help the electronic feedback devices in temperatures exceeding 175°C (347°F). Leading oil and gas exploration and drilling companies have worked with CoorsTek to develop ceramic-electronic technologies that successfully operate and have a significant life expectancy in environments exceeding 200°C (400°F), perfect for reservoirs in Mexico, Southeast Asia, Australia, Africa and the Gulf of Mexico.
