• Corion Express Wireline Retrievable Coring

    Traditional wireline coring systems retrieved 2” diameter or smaller core samples due to limitations imposed by industry standard BHA components and drillstring tool joint internal diameters (IDs). With an innovative, forward thinking design, the Corion Express™ system allows the retrieval of cores up to 3 ½” in diameter. It works through drill pipe with tool joint IDs 4 ¼” or larger. The system works for land and offshore operations, in conventional and unconventional applications, and allows coring of targets from mudline to any depth. With unlimited core, log, and drill cycles, time savings, and superior core retrieval, the Corion Express system provides a substantial economic benefit to your operations.

    Traditional wireline coring systems retrieved 2” diameter or smaller core samples due to limitations imposed by industry standard BHA components and drillstring tool joint internal diameters (IDs). 

    With an innovative, forward thinking design, the Corion Express system allows the retrieval of cores up to 3 ½” in diameter. It works through drill pipe with tool joint IDs 4 ¼” or larger. 

    The system works for land and offshore operations, in conventional and unconventional applications, and allows coring of targets from mudline to any depth . With unlimited core, log, and drill cycles, time savings, and superior core retrieval, the Corion Express system provides a substantial economic benefit to your operations.

    Express 4.0 Wireline Retrievable Coring
    The Express 4.0 system allows the retrieval of cores up to 3” in diameter. For this system, we adapted the design of our Corion Express system to work through drill pipe with tool joint IDs as low as 4”, allowing you to retrieve large diameter cores without requiring specialized drill pipe.

    Features/Benefits

    Time Savings – Reduced time spent tripping reduces overall rig costs
    Minimal Costs – Compatibility with standard drill pipe reduces rental, transport and inspection costs
    Unlimited Cycling – Can core, drill, or log as needed
    Large Cores – Retrieves samples up to 3 ½” (Corion Express system) or 3” (Express 4.0) in diameter
    High-Quality Samples – Large-diameter coring provides more core volume without fluid contamination
    Supporting Technology – Fully compatible with NOV provided coring collars and jars
