Casing Drilling ® Services TESCO’s CASING DRILLING® technology is changing the way wells are drilled. The CASING DRILLING® process generates value for the operator by keeping assets protected behind casing as the drilling proceeds. With easily tapped reservoirs in decline, difficult wells are generating more trouble and non-productive time. CASING DRILLING® provides a solution for a number of well shapes and challenges including vertical, horizontal, under-balanced, offshore and onshore, difficult geo-mechanical environments, hard and soft formations among others. CASING DRILLING® is most effective in areas where hole problems have been severe with drill pipe such as lost returns, wellbore stability and well control. TESCO’s experience in CASING DRILLING® provides a greater chance of success when drilling through difficult intervals. TESCO has a long history of delivering value to our customers with our CASING DRILLING® process. While CASING DRILLING®, TESCO has run numerous retrievable bottom hole assemblies (BHA) with reliability approaching 100%. TESCO has drilled intervals directionally up to 90 degrees and 150 degree azimuth turns. Hole diameters range from 6” to 17-1/2” in both oil and water based mud systems. In underbalanced or high-pressure applications, well control is simplified as casing is allways on bottom. Expanding its products and services globally, TESCO offers directional CASING DRILLING ® with rotary steerable technology to vertical drill-in with drillable shoes. TESCO’s focus is to be rigged up and ready to run or retrieve a CASING DRILLING® BHA within a few hours on any drilling contractor’s rigs. TESCO is building equipment to rig up below the top drive and CDS to run wireline, circulate the wellbore, reciprocate casing and maintain well control while tripping BHAs. This means major rig conversions are not needed for CASING DRILLING®. And, TESCO simplifies its tools – minimizing wireline operations and improving efficiencies. CASING DRILLING ® eliminates drill string tripping, making it a safer and more cost effective method of drilling. CASING DRILLING ® helps avoid unscheduled events, saves operating and labor costs and reduces capital investment. The asset-intensive environment of offshore drilling dramatically illustrates CASING DRILLING ® efficiencies. p a g e 1 0
