There are moments when the challenge is not the environment, the pressure or the reliability. Shallow, marginal low-pressure well production dictates a very tight budget. The oil company then needs to maximize its use of customer property and to utilize the adequate technology to match its application. There is not extra cash for any luxury beyond the basic requirements. At FMC Surface Wellhead we listened to market situations and decided to develop our FH line with tapered bowl and exclusive elastomer seal design to stay “on budget.”

Our customer’s infield drilling program needed to minimize his rig time for multiple shallow wells (with surface casing pressures less than 5,000 psi) and to improve safety. FMC Surface Wellhead’s solution was the DTO®wellhead, which delivers significant time savings by eliminating a number of steps in the traditional drilling process and reducing time required for other steps. The ideal situation for using the DTO would be a single rig that’s drilling multiple consecutive wells by using a common casing program. Each rig is outfitted with a DTO diverter connector fabricated into a diverter riser. The assembly stays with the rig for the drilling project, and it is used on each well. A DTO drilling spool connector is assembled into the rig BOP and is moved with the rig from well to well.
F e a t u r e s a n d B e n e f i t s
◆ Eliminates steps in the drilling process.
◆ Offers time savings during nipple up/down of the BOP’s stack, landing casing hanger and installing the tubing head.
◆ Increases safety by eliminating the need for cutting torches and hammer wrenches.
◆ Locking ring design on drilling spool provides 360 degrees engagement to increase load capacity and reduce fatigue.
◆ Contingency systems for stuck pipe retains system benefits and time savings.
◆ Tests production casing seals prior to removal of BOP.
◆ Load capacity of surface casing hanger exceeds joint strength.

This major European-based oil company planned to develop a high-flow-rate, corrosive field in Borneo. Not only does this company uphold the highest standards for safety of crew and environment, but it would be operating in a part of the globe that it had not previously explored. The company came to FMC Energy Systems for its reputation as a worldwide supplier familiar with the Far East and the challenges of working here, and known for the high reliability of our wellhead systems. Energy Systems sales engineers recommended technology appropriate to the highest standard required, a fully featured system with metal-to-metal seals and Speedloc®connections. We knew this would be the best cost-to-risk choice for the customer, who would not have to be concerned about the equipment performance over the life of the field. They also felt such a system would be easier and safer to install and safer over the life of the wells, and that it would save them rig time during installation.

When a major oil company planned to develop a North Sea field, it estimated a 30-year minimum lifetime for the field and projected future production with water cuts and gas penetration. The field would have 12 tie-back wells (predrilled wells from a semi prior to installing the platform) and was planned for production, gas-injection and water-injection wells. Moreover, the field is regulated by strict API6A and NORSOK standards. Needing reliable, flexible, cost-effective drilling and production solutions, this company came to FMC Energy Systems as we are the most experienced well-head supplier in the North Sea for both surface and subsea applications. Our engi-neers proposed a fully featured surface system using thru-bore technology, including proven UWD 15 subsea technology, with the flexibility of switching from production to injection without changing trees. FMC Energy Systems’ Norway operations allow the customer to carry smaller inventories of equipment and parts, short lead time and ready access to engineers and technicians experienced in North Sea operations.
F e a t u r e s a n d B e n e f i t s

This project in the China Sea’s Ya Cheng field, which supplies gas energy to Hong Kong, presented the challenges of critical conditions: high corrosive, high temperature, fire resistant, severe weather, large-bore production, high reliability and a long life cycle to reduce the need for workovers. Our state-of-the-art “dry tree” system, the UWD-15, is an excellent example of our quest to design highly reliable wellheads for difficult environments and conditions and still contain costs. Developed out of our subsea wellhead technology, the UWD-15 is a 15,000 psi wellhead that combines advanced technology for high-pressure and hazardous-service environments. All seals are metal-to-metal, with the UWD-15 packoff providing the basis for annular sealing. This packoff does not rely on the tubing hanger weight to energize and can be removed separately from the tubing hanger. It utilizes an SBMS seal at the tubing hanger neck as standard. The seat is recessed to help ensure that the seal contact surface is not damaged when the packoff is installed.
The design includes a fire-safe envelope for the upper master valve to the annulus A.

Injecting 1.2 million cubic feet of nitrogen per day into a formation through a 9˝ bore is a major challenge to face with traditional solu-tions. The limited available height and weight on the platform plus the handling of a 9˝ Christmas tree during installation and workover ruled out a conventional production wellhead solution. Our engineers who have platform working experience understood better than other suppliers the operational challenge, and proposed the first horizontal wellhead tree system of its size in the Gulf of Mexico.

Fragmented reservoirs requiring multiple interventions are a major challenge due to the reduced space on platforms, especially when, as in this example, you need to complete (or abandon) wells and perform interventions without disturbing adjacent wells. For such challenges, FMC Surface Wellhead has developed a Side-By-Side (SXS) Wellhead System for optimization of space on new platforms or workovers on existing platforms. The SXS also accommodates configurations involving a combination of single and dual completions inside a single conductor.
F e a t u r e s a n d B e n e f i t s
◆ Allows installing either a 2-in-1 or 3-in-1 well configuration inside a single conductor, sized from 26˝ OD onwards to suit requirements.
◆ Eliminates the need for additional conductor pipe. This creates up-front savings and reduces abandonment costs.
◆ Allows the use of standard drill-bit sizes.
◆ Independent Tubing Heads (Unihead®) allow greatest flexibility in choosing wells to complete or abandon and to perform independent intervention, entry and re-entry without disturbing adjacent wells or flow lines. The wellheads are installed with full BOP protection. This system promotes time saving through batch drilling and drilling with reduced rig move time.
◆ Maximize platform size and the use of well slots on the platform. For existing wells, the SXS wellhead maximizes the use of existing spare well slots.

By far the most experienced suppliers of TLP/SPAR systems in the Gulf of Mexico, we also installed the deepest and most fire-resistant SPAR in the Gulf.
As certain platforms are designed to move with water action, every element connected to the sea floor becomes an integral part of a dynamic system and requires specialized wellhead solutions like our TLP/SPAR systems. From the initial stages of your project, we can help you decide to go with a “wet” or a “dry” tree.
Example: If you’re facing a fragmented reservoir offshore and must execute multiple interventions, economics indicate a surface tree.
FMC Surface Wellhead installed the first TLP/SPAR system in the Gulf of Mexico during the 1980s and has been the leader in this technology since, installing more systems worldwide than our competitors combined.
