PACE™ 750
The PACE™ 750 is a programmable AC electric rig with PLC controls, allowing the driller to control the drawworks, the top drive, the mud pumps and virtually every other significant piece of equipment from a central control center. This compact, powerful rig was designed to drill to a broad range of depths in a variety of geographical and geological areas. It is engineered to move rapidly, reducing the time between wells. |

PACE™ 1,500
The PACE™ 1,500 is a larger version of the PACE™ 750. It is also programmable AC electric and PLC controlled, but has a stronger mast and substructure and an additional mud tank, allowing it to drill the deeper horizontal wells that are frequently required today. |

PACE™ 2000 AND PACE™ 3000
Worldwide drilling is going deeper, especially for natural gas in the Middle East. All of this requires special purpose ultra-deep capacity drilling rigs. Nabors has been engaged in a proactive building program to meet this demand and has produced twelve 2,000 and five 3,000 HP rigs incorporating the latest in performance-enhancing features. These rigs are easily adapted to the “lift and roll” moving system and automated pipe handling systems, and are equipped with a system for pre-assembly of drill pipe stands. |

ARCTIC
Nabors pioneered cold-weather drilling, having drilled some of the most important wells on Alaska's North Slope and in Canada. The company is a leader in winterizing rigs for harsh environments and originally developed pad drilling techniques which are now being used all over the world to move rigs between wells more rapidly.

SUPERSUNDOWNER MODS SERIES
Nabors continues to expand its fleet of proprietary MODS and SuperSundowner (SSD) offshore platform rigs. These rigs have realized extraordinarily high utilization due to their light weight, small footprint and ease of mobilization and demobilization. MODS rigs are drilling rigs available in 1,500-, 2,000- and 3,000-horsepower depth ratings while SuperSundowner rigs are ideally suited for heavy workover, re-entry and re-drilling applications, as well as medium-depth drilling projects. MODS rigs are designed specifically to accommodate the motion characteristics of deepwater floating SPAR and tension leg platforms, while SuperSundowners can easily be upgraded to similar capability. |

BARGE – 35,000' CAPABILITY
Nabors constructed barge Rig 300 in 2005 and has subsequently undertaken the construction of barge Rig 301 and barge Rig 100, both of which will deploy in early 2007. These rigs are geared towards the ultra-deep gas prospects in the shallow waters of the Gulf of Mexico. Barge Rig 100 is designed for deep workover and/or shallow drilling, while barge Rigs 300 and 301 are capable of drilling to 35,000 feet in water depths as shallow as seven feet. |

COILED TUBING/STEM DRILLING
Nabors is constructing 13 Hybrid AC Coiled Tubing Rigs for operations in shallow oil and gas plays in Canada and the U.S. The company has completed eight of these units with the balance due in 2007. These rigs combine the benefits of continuous drilling with the flexibility to switch to jointed pipe as necessary. Coil drilling has been used extensively in Canada in recent years, drilling wells at higher rates of penetration and reduced cycle times to allow more wells to be drilled in a given period of time. The technique is gaining momentum in the U.S. where it is beginning to demonstrate its ability to improve performance in shallower and directional drilling applications. |

HELI-PORTABLE RIG
Nabors Canada is developing heli-portable drilling, well-servicing and well site construction systems to provide year-round access to remote or environmentally-sensitive locations. The key enabler of these drilling systems is the use of the Russian MI-26T, the largest helicopter in the world, which has been working reliably and safely in Siberia and around the world for many years. The new rigs are state-of-the-art programmable AC electric rigs with a small footprint configuration, light loads and heated pipe sheds for Arctic operations. They are very competitive in the conventional drilling mode and can be moved by numerous methods for all-weather, all-season access to remote locations. Two of these heli-portable drilling rigs will deploy on long-term contracts in 2007, with more slated for construction. |

WELL-SERVICING 200 SERIES
The new 200 series rig is ideal for servicing shallow, closely spaced wells in rugged terrain. Its shorter wheelbase and drive-in capability give the driver improved visibility and greater maneuverability, critical features when working in tight quarters. An advanced instrumentation system gives the operator real-time performance monitoring of the rig. |

WELL-SERVICING 400-500 SERIES
Millennium Rigs from Nabors Well Services are a breakthrough in workover and well-servicing. Six years in Millennium Rigs from Nabors Well Services are a breakthrough in workover and well-servicing. Six years in design and construction, they combine a variety of features which make them safer, more efficient, more durable and easier to operate. Available in 400- and 500-horsepower models, these rigs are designed to service the increasing population of deeper and more directional wells. A total of 39 are currently deployed, with another 141 scheduled for delivery by early 2009. |
