1 GE Oil & Gas Subsea Wellhead Solutions Advanced technologies with industry-proven reliability, performance, and safety for all operating conditions

2 Reliability is a must Offshore operations are moving into deeper waters, more remote locations, and more challenging environments with increasing temperatures and pressures. As they push past the boundaries of 10,000 ft (3,000 m) depths and 30,000 ft (9,100 m) wells, financial pressure and technological complexity increase exponentially. In these scenarios, collaboration among oil and gas players is fundamental to provide the industry with production systems and expertise to enable optimized, ultra-reliable performance throughout life-of-field. GE pushes the technology boundaries needed to increase reliability, flexibility, speed and performance. With more than 40 years of infield experience and over 1,000 systems installed worldwide, our heritage includes robust casing connectors dating back to the 1960s and game changing wellhead designs back to the early 1990s. The driving force behind our successful technology has always been a design approach that draws from our customers actual infield experience, and their evolving need for higher efficiency and dependability. Through collaboration and commitment, our people have delivered such innovations as the patented MS metal-to-metal sealing technology, robust wellheads and connectors now used around the world. Today, we continue to partner with operators, technology and services providers to enable safe, sustainable, and reliable growth in the offshore industry. Our products are designed, tested and proven for industry-leading performance, safety and efficiency in a wide range of operating conditions. We tap into the full breadth of experience across all GE s different industrial sectors from healthcare to aviation, power and water and apply it to oil and gas. We call this synergetic approach the GE Store. It unlocks the power of over 50,000 technology experts around the globe who are continually inventing the new industrial age helping us bring innovative solutions to the market faster and more cost effectively. collaborating for speed To help projects overcome increasing capital costs, we develop standardized configurable solutions that improve speed to market and enhance operations. Our innovative FastWorks approach to product development combines tools and behaviors that deliver better outcomes for customers, faster. FastWorks is reshaping our business culture and the way we collaborate with customers, bringing all project teams together under a unified goal. It s already helped deliver more than 75 MS-700 subsea wellhead systems with industryleading delivery schedules well ahead of customer due dates.

3 Standard features of GE subsea wellheads Dual tapered socket load transfer (up to 7 million ft-lbs) Passive load shoulder (7 and 8 million lbs load capacity) High pressure housing lockdown load rating (4 million lbs) Full metal-to-metal, pressure-set seals tested to 350 F Secondary metal seal areas Maximum system flow-by (16 sq. in.) Casing hanger flow-by particle size of 0.75" High-pressure to low-pressure housing hydrate seal Reliable running tools Proven time savings in deepwater with Trip Saving Tools Manufactured to the latest industry standards, API 17D and 6A Superior preload Effective transfer loading from the high-pressure housing into the low-pressure housing is critical to reduce fatigue. GE Oil & Gas achieves this with a unique patented dual-tapered socket design. Our passive preloaded style wellhead makes a rigid connection through radial preloading generated by weight without the use of bootstrap or preload tooling typical of axial preloaded wellhead designs. The tapered socket interface uses a multiple-step latch design that delivers high capacities in minimal space. The heavy-duty latch, rated for 4 million lbs lockdown capacity, is standard for our latest generation of MS-700, MS-800, and SFX wellhead systems. The design has an ultimate capacity of over 6 million lbs to beat the demanding requirements of deepwater drilling with dynamically positioned rigs. A bulk rubber o-ring and Xylan coating ensure full-rated capacity is still achieved after extended periods subsea. 5

4 Advanced connector profiles The H-4 connector family is a GE patented design that has been adopted industry wide for its leading reliability dating back to Smartly engineered with simple operating characteristics and advanced metal-to-metal sealing, the modern hydraulically operated H-4 provides excellent bending and tensile load capabilities, and a long, economical service life. It s also highly versatile and field-proven for BOP stack to wellhead, LMRP to BOP stack, and completion tree to wellhead connections. Wellhead ring gaskets Seals the wellhead to H-4 interface Achieves complete gas-tight sealing up to 20,000 psi Available in VGX-2 high temperature, high-pressure version Also available in VT-2 secondary seal surface version VX-2 & VGX-2 Seal Taper VT-2 Seal Taper (Secondary) VX-2 Cadmium plated, carbon steel rated for 10,000 psi or stainless steel rated for 15,000 psi at 250 F VT-2 Secondary seal with independent seal surface used when VX profile is damaged.

5 MS-700 subsea wellhead system Since launched in 1991, our MS-700 remains one of the most widely used subsea wellhead systems in the world. Its versatility has been proven across TLP/spar tieback, exploration, subsea completion and deepwater drilling applications. Fundamental to its design is our proven Metal Sealing (MS) technology superior to elastomer options because it prevents inevitable heat and corrosive fluids from damaging seal integrity, making it one of the most reliable metal-to-metal seal offered in the industry. SFX standardized solution for fatigue applications SFX takes our field-proven architectures to the next level with up to 16 times fatigue improvement. The optimized design is simpler, faster and stronger delivering ultra reliability in your worst fatigue conditions. SFX will also greatly simplify your entire procurement process, since the full range of optimized wellheads and connectors can be easily obtained from a single source all adhering to the same high standards for design, testing and manufacturing. Key features Allows additional casing string to be hung under the wellhead Includes a single trip running tool to test both the casing hanger and the annulus seal High pressure and temperature capabilities ( F) Up to 7 million ft-lbs bending capacity 7 million lbs load capacity allows for 3 casing strings (up to 1 million lbs each) Simpler Harmonized specification across global operations One supplier for wellhead and connectors Based on field-proven technology Faster 4 5 Quicker response and delivery time Global manufacturability Reduced number of welds and post weld processes MS-800 subsea wellhead system Developed in 2007 and based on decades of proven technology, MS-800 is a cost-effective full bore system that can be utilized in all applications including shallow water and deepwater wells. The MS-800 enables operators to run one extra casing string under BOP control with a 21" drilling riser. The system also allows more flexibility in designing casing programs by using larger drill bits, testing packoffs to higher pressures, and having the option to run 18" and 16" casing strings below the mudline. MS-800 allows potentially larger completion options, by reaching total depth with a larger production string. Key features 8 1. VX/VT gasket profile 2. H4 connector profile 3.
