DL High-pressure annular BOP DL BOP The Cameron DL high-pressure annular BOP allows reliable performance in a shorter height and lighter weight than comparable annular BOPs. The unique design of the DL BOP does not require wellbore assist. The annular can close on drillpipe or large tubulars without reducing operating pressure, which minimizes risk of indention or damage to casing. ■■ Sizes: 7-1/16” to 21-¼” ■■ Working Pressures: 2,000 to 10,000 psi ■■ Dual configurations available for certain sizes ■■ Each packer assembly has passed API 16A qualification testing Packer with interlocking segments Functionality Closing pressure forces the operating piston and pusher plate upward to displace the solid elastomer donut and force the packer to close inward. As the packer closes, interlocking-steel reinforcing inserts rotate inward to form a continuous support ring of steel at the top and bottom of the packer. The inserts remain in contact with each other whether the packer is open, closed on pipe, or closed on open hole.

The design also provides visual indication of whether the top is locked or unlocked Components subject to wear are field-replaceable and the entire operating system may be removed in the field for immediate changeout, without removing the BOP from the stack Twin seals separated by a vented chamber positively isolate the BOP operating system from wellbore pressure. High-strength polymer bearing rings prevent metal-to-metal contact and reduce wear between all moving parts of the operating system vailable with a three-inch gas bleed port that runs from the inner A diameter to the outer diameter P ackers for DL BOPs have the capacity to strip pipe as well as close and seal on any size object that fits in the wellbore. These packers will also close and seal on open hole at half working pressure S tripping packers are available and reference information is available in TC9609 E-24 Popular sizes of the DL BOP are available with high-performance CAMULAR* elastomer technology annular packer subassemblies Manufactured to comply with NACE specification MR-01-75 for H2S service DL BOP Dimensional Information Size and working pressure Height, in/mm Diameter, in/mm Weight, lb/kg Gal/L to close Gal/L to open 7-1/16" 3,000 psi 23.94/557 27.88/708 2,738/1,241 1.69/6 1.39/5 7-1/16" 5,000 psi 25.50/647 27.88/708 2,778/1,260 1.69/6 1.39/5 7-1/16" 10,000 psi 34.22/869 37.38/949 7,255/3,290 2.94/11 2.55/9 7-1/16" 15,000 psi 44.75/1,136 43.25/1,098 12,000/5,443 6.94/26 6.12/23 7-1/16" 20,000 psi 50.75/1,289 48/1,219 17,716/8,035 8.38/31 7.56/28 11" 3,000 psi 32.50/825 41.25/1,047 8,255/3,744 5.65/21 4.69/17 11" 5,000 psi 34.94/887 41.25/1,047 8,447/3,831 5.65/21 4.69/17 11" 10,000 psi 41.06/1,042 48.50/1,231 13,954/6,239 10.15/38 9.05/34 11" 15,000 psi 62.50/1,587 61/1,549 36,500/16,556 23.50/88 21.3/80 13-5/8" 3,000 psi 36.69/931 52.38/1,330 12,855/5,830 12.12/45 10.34/39 13-5/8" 5,000 psi 40.19/1,020 52.38/1,330 16,215/7,355 12.12/45 10.34/39 13-5/8" 10,000 psi 49.09/1,246 61/1,549 27,262/12,365 18.10/68 16.15/61 16-3/4" 3,000 psi 47/1,193 60.50/1,536 25,950/11,770 22.30/84 19.00/71 16-3/4" 5,000 psi 49/1,244 60.50/1,536 26,300/11,929 22.30/84 19.00/71 18-3/4" 5,000 psi 60.81/1,544 62/1,574 29,560/13,408 35.60/134 29.00/109 18-3/4" 10,000 psi 70.50/1,790 67/1,701 40,940/18,570 51.00/193 45.10/170 20-3/4" 3,000 psi 54.75/1,390 66/1,676 29,500/13,380 40.50/153 28.40/107 21-1/4" 2,000 psi 53.31/1,354 66/1,676 29,000/13,154 40.50/153 28.40/107 21-1/4" 5,000 psi 64.84/1,646 71.69/1,820 36,000/16,329 40.50/153 28.40/107 DL BOP cameron.slb/DLBOP * Mark of Schlumberger Other company, product, and service names are the properties of their respective owners.
