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.

New Baker Hughes Water Treatment Improves Efficiency, Reduces Costs

?HOUSTON, TEXAS – Oct. 31, 2011 – A new Baker Hughes water treatment technology cost-effectively removes suspended solids and heavy metals without chemicals and treats 100% of flowback and produced water for reuse.

The H2prO™ water treatment service uses an exclusive electrocoagulation technology that reliably eliminates contaminants without chemicals and reduces costly non-productive time. The service combines high mobility and proven technology to conserve freshwater use; reduces transportation and disposal costs and complies with all regulatory requirements.

“This service addresses water supply limitations and enhances the pace of our customers’ pressure pumping operations,” says Tom Whalen, Baker Hughes’ Vice President of Water Management. “We improve overall efficiency of operations and reduce total water cost because this is part of a fully integrated process from pressure pumping to water treatment and disposal.”

Application starts with in-depth water tests to analyze the unique characteristics of each well or other water source. Next, Baker Hughes mobilizes the right water treatment equipment to enable operators to reuse the water for drilling or hydraulic fracture. This pre-treatment analysis reduces the risk of formation damage.

“Operators are no longer constrained by permanent equipment that may not be ideal for their needs,” Whalen adds. “We work with each operator on an individual basis to come up with a collaborative plan to conserve water, reduce transportation and disposal costs and design the best solution for each basin, reservoir or field to recycle and reuse produced and flowback water. We have the field proven technology, solutions and the equipment operators who look to us need.”
