Baker Hughes Introduces Rigless Intervention System

HOUSTON, TEXAS (May 2, 2012) – Baker Hughes’ new mechanized, self-pinning rigless intervention system, Mastiff™, provides operators an alternative method for carrying out pipe installation and retrieval operations, which typically require a costly offshore rig. By eliminating the need for a rig, the Mastiff Rigless Intervention System (RIS) can reduce the cost of abandonment, workover and drive pipe pre-installation operations.

The Mastiff RIS’ modular design and light weight make it ideal for operations on platforms with limited load capacity and is easily deployed worldwide. With a maximum weight of 24,000 pounds (10886 kg), each RIS module can be transported in a standard 40-foot (12-meter) open-top container.

The Mastiff RIS has a self-pinning mast erection system that improves safety and enables the unit to be rigged up or rigged down in 24 to 48 hours. Hydraulics built into the system enable the modular components to be assembled and disassembled using a hydraulic, self-pinning design, eliminating the need for riding belt operations, and dramatically reducing risks associated with working at height and manual handling of components. The system’s sturdy mast enables safe operation at wind speeds of up to 50 mph (43.5 knots).

The system has a 352-ton pulling capacity. While performing conductor pipe removal, the Mastiff RIS can support cutting and pulling lifts of 50-foot sections of 36-inch conductor pipe, inner casing and cement, a significant improvement over casing jack systems, which work with 5-foot sections.

As an alternative to well abandonment, the Mastiff RIS can be used to initiate a slot recovery program for continued field development prior to the arrival of the drilling rig. Once the pipe is removed, the well slot can be prepared for a new, full-sized wellbore using a full-range of equipment from drive-pipe whipstocks to hammer services, saving valuable rig time and offering the operator the option to further redevelop assets.

Baker Oil Tools' Newest Inflatable Service Packer Reduces Well Construction and Intervention Costs in Heavy-Duty Drilling Applications

HOUSTON (Feb. 14, 2003) – Baker Oil Tools’ new Blue Whale™ Inflatable Service Packer (ISP) is a high-expansion inflatable service tool designed for heavy-duty drilling applications. The Blue Whale ISP replaces a collection of tools with a single, simple tool that operates reliably in a range of environments to reduce total well construction and intervention costs.

Ability to seal a wide range of casing and open-hole sizes in critical applications fills ;important gap on deepwater rigs.

“Zone isolation in large-diameter casing and open holes offshore used to require a long list of packers, procedures, and secondary tools for each job. The Blue Whale has changed that,” said Baker Oil Tools Inflatables Product Line Manager Gordon Mackenzie. “The Blue Whale answers the need for a single tool that will seal a wide range of casing and openhole sizes in critical applications. On deepwater rigs -- where rig time, space, and transportation are expensive -- the Blue Whale can pay for itself quickly.”

The large contact area of the Blue Whale's inflatable sealing element allow it to anchor and seal reliably in wellbore
conditions such as soft formations, older and deteriorated casing, and fiberglass casing that pose problems for traditional mechanical service tools. The element inflates with most drilling fluids and pump pressure. Tubing weight is not required to set the tool.

Blue Whale ISP technology is based on the Baker Oil Tools Inflatable PIP (Production Injection Packer), the world's first
inflatable packer and the pioneer of all inflatable service tools. The Blue Whale can function as a permanent or retrievable bridge plug, a service packer, or a permanent cement retainer in cased or open hole. Its inflatable element allows for expansion ratios of greater than 200 percent after passing through wellbore restrictions. Additionally, a wide range of available accessory tools can be run with the Blue Whale ISP to perform many remedial operations in large-diameter hole.

Baker Oil Tools' proprietary INFLATEDESIGN™ software is a key component of the Blue Whale ISP system. INFLATEDESIGN eliminates guesswork by allowing precise definition of the Blue Whale’s performance envelope in a
given application. INFLATEDESIGN assists with information gathering, execution and post-job reporting, and can be used to consult with Baker Oil Tools inflatable systems experts onshore.

Baker Oil Tools is a world leader in total completion, workover, and fishing solutions that help exploration and
production companies optimize their hydrocarbon recovery investment. Baker Oil Tools solutions are based on advanced
downhole and surface technology, practically applied, to help operators produce at the highest levels and the lowest cost
throughout the life of the reservoir.

Baker Hughes is a leading provider of drilling, formation evaluation, completion and production products and services to the worldwide oil and gas industry.
