Description of Oil States International Inc's Business Segments
In operation for 75 years, our Offshore Products segment provides a broad range
of products and services for use in offshore development and drilling activities.
This segment also provides products for onshore oil and natural gas, defense and
general industries. Our Offshore Products segment is dependent in part on the
industrys continuing innovation and creative applications of existing technologies.
We own various patents covering some of our technology, particularly in our connector
and valve product lines.
Offshore Development and Drilling Activities. We design, manufacture, fabricate,
inspect, assemble, repair, test and market OEM equipment for mooring, pipeline,
production and drilling risers, and subsea applications along with equipment for
offshore vessel and rig construction. Our products are components of equipment
used for the drilling and production of oil and natural gas wells on offshore
fixed platforms and mobile production units, including floating platforms, such
as tension leg platforms, floating production, storage and offloading (“FPSO”)
vessels, Spars, and other marine vessels, floating rigs and jack-up rigs. Our
products and services include:
flexible bearings and advanced connection systems;
casing and conductor connections and joints;
subsea pipeline products;
compact ball valves, manifold system components and diverter valves;
marine winches, mooring systems, cranes and other heavy-lift rig equipment;
production, workover, completion and drilling riser systems and their related
repair services;
blowout preventer (“BOP”) stack assembly, integration, testing and
repair services;
consumable downhole products; and
other products and services, including welding, cladding and other metallurgical
technologies.
Flexible Bearings and Advanced Connection Systems. We are the key supplier of
flexible bearings, or FlexJoint® connectors, to the offshore oil and natural
gas industry as well as weld-on connectors and fittings that join lengths of
large diameter conductor or casing used in offshore drilling and production
operations. A FlexJoint® is a flexible bearing that allows for rotational
movement of a riser or tension leg platform tether while under high tension
and/or pressure. When positioned at the top, bottom and, in some cases, middle
of a deepwater riser, it reduces the stress and loads on the riser while compensating
for the pitch and rotational forces on the riser as the production facility
or drilling rig moves with ocean forces. FlexJoint® connectors are used
on drilling, production and export risers and are used increasingly as offshore
production moves to deeper water areas. Drilling riser systems provide the vertical
conduit between the floating drilling vessel and the subsea wellhead. Through
the drilling riser, the drill string is guided into the well and drilling fluids
are returned to the surface. Production riser systems provide the vertical conduit
for the hydrocarbons from the subsea wellhead to the floating production facility.
Oil and natural gas flows to the surface for processing through the production
riser. Export risers provide the vertical conduit from the floating production
facility to the subsea export pipelines. Our FlexJoint® connectors are a
critical element in the construction and operation of production and export
risers on floating production systems in deepwater.
Floating production systems, including tension leg platforms, Spars (defined
below) and FPSO facilities, are a significant means of producing oil and natural
gas, particularly in deepwater environments. We provide many important products
for the construction of these facilities. A tension leg platform (“TLP”)
is a floating platform that is moored by vertical pipes, or tethers, attached
to both the platform and the sea floor. Our FlexJoint® tether bearings are
used at the top and bottom connections of each of the tethers, and our Merlin™
connectors are used to efficiently assemble the tether joints during offshore
installation. An FPSO is a floating vessel, typically ship shaped, used to produce
and process oil and natural gas from subsea wells. A Spar is a floating vertical
cylindrical structure which is approximately six to seven times longer than
its diameter and is anchored in place. Our FlexJoint® connectors are used
to attach the various production, injection, import or export risers to all
of these floating production systems.
Casing and Conductor Connections and Joints. Our advanced connection systems
provide connectors used in various drilling and production applications offshore.
These connectors are welded onto pipe to provide more efficient joint to joint
connections with enhanced tensile and burst capabilities that exceed those of
connections machined onto plain end pipe. Our connectors are reusable and pliable
and depending on the application are equipped with metal-to-metal seals. We
offer a suite of connectors offering differing specifications depending on the
application. Our Merlin™ connectors are our premier connectors combining
superior static strength and fatigue life with fast, non-rotational make-up
and a slim profile. Merlin™ connectors have been used in sizes up to 60
inches (outside diameter) for applications including open-hole and tie-back
casing, offshore conductor casing, pipeline risers and TLP tendons (which moor
the TLP to the sea floor).
These flexible bearings and advanced connector systems are primarily manufactured
through our Arlington, Texas, United Kingdom and Singapore locations.
Subsea Pipeline Products. We design and manufacture a variety of equipment used
in the construction, maintenance, expansion and repair of offshore oil and natural
gas pipelines. New construction equipment includes:
pipeline end manifolds and pipeline end terminals;
deep and shallow water pipeline connectors;
midline tie-in sleds;
forged steel Y-shaped connectors for joining two pipelines into one;
pressure-balanced safety joints for protecting pipelines and related equipment
from anchor snags or a shifting sea-bottom;
electrical isolation joints; and
hot-tap clamps that allow new pipelines to be joined into existing lines without
interrupting the flow of petroleum product.
We provide diverless connection systems for subsea flowlines and pipelines.
Our HydroTech® collet connectors provide a high-integrity, proprietary metal-to-metal
sealing system for the final hook-up of deep offshore pipelines and production
systems. They also are used in diverless pipeline repair systems and in future
pipeline tie-in systems. Our lateral tie-in sled, which is installed with the
original pipeline, allows a subsea tie-in to be made quickly and efficiently
using proven HydroTech® connectors without costly offshore equipment mobilization
and without shutting off product flow.
We provide pipeline repair hardware, including deepwater applications beyond
the depth of diver intervention. Our products include:
repair clamps used to seal leaks and restore the structural integrity of a pipeline;
mechanical connectors used in repairing subsea pipelines without having to weld;
misalignment and swivel ring flanges; and
pipe recovery tools for recovering dropped or damaged pipelines.
Our subsea pipeline products are primarily designed and manufactured at three
of our Houston, Texas manufacturing locations.
Compact Ball Valves, Manifold System Components and Diverter Valves. Our Piper
Valve division designs and manufactures compact high pressure valves and manifold
system components for all environments of the oil and gas industry including
onshore, offshore, drilling and subsea applications. Our valve and manifold
bores are designed to closely match the inside diameter of the required pipe
schedule for the system working pressure. The result is elimination of piping
transition areas that minimize erosion and system friction pressure loss, resulting
in a more efficient flow path. Our floating ball valve design with its large
ball/seat interface has over 30 years of field service experience in upstream
unprocessed produced liquids and gasses, assuring reliable service. Oil States
Piper Valve Optimum Flow Technology is our way of helping end users maximize
space, minimize weight and increase production. These products are designed
and manufactured at our Oklahoma City, Oklahoma location.
Marine Winches, Mooring Systems, Cranes and other Heavy-Lift Rig Equipment.
We design, engineer and manufacture marine winches, mooring systems, cranes
and certain rig equipment. Our Skagit® winches are specifically designed
for mooring floating and semi-submersible drilling rigs as well as positioning
pipelay and derrick barges, anchor handling boats and jack-ups, while our Nautilus®
marine cranes are used on production platforms throughout the world. We also
design and fabricate rig equipment such as automatic pipe racking, blow-out
preventer handling equipment, as well as handling equipment used in the installation
of offshore wind turbine platforms. Our engineering teams, manufacturing capability
and service technicians who install and service our products provide our customers
with a broad range of equipment and services to support their operations. Aftermarket
service and support of our installed base of equipment to our customers is also
an important source of revenue to us. These products are provided through our
Houma, Louisiana; Navi Mumbai, India; and Rayong, Thailand locations.
Production, Workover, Completion and Drilling Riser Systems and their related
repair services. Utilizing the expertise of our welding technology group, we
have extended the boundaries of our MerlinTM connector technology with the design
and manufacture of multiple riser systems. The unique MerlinTM connection has
proven to be a robust solution for even the most demanding high-pressure (up
to 20,000 psi) riser systems used in high-fatigue, deepwater applications. Our
riser systems are designed to meet a range of static and fatigue stresses on
a par with those of our Tension Leg Elements (“TLE”) connectors.
The connector can be welded or machined directly onto upset riser pipe and provide
sufficient material to perform "re-cuts" after extended service. Our
marine riser offers superior tension capabilities together with one of the fastest
run times in the industry. Auxiliary riser system components and running tools
can be provided along with full service inspection and repair of these riser
systems by our facilities worldwide.
BOP Stack Assembly, Integration, Testing and Repair Services. While not typically
a manufacturer of BOP components, we design and fabricate lifting and protection
frames for BOP stacks and offer the complete system integration of BOP stacks
and subsea production trees. We can provide complete turnkey and design fabrication
services. We also design and manufacture a variety of custom subsea equipment,
such as riser flotation tank systems, guide bases, running tools and manifolds.
In addition, we also offer blow-out preventer and drilling riser testing and
repair services. These assembly and testing services are offered through our
Houston, Texas, United Kingdom, Singapore and Brazil locations.
Consumable Downhole Products. North American shale play development has expanded
the need for more advanced completion tools. To reduce well completion costs,
minimizing the time to drill out tools is very important. Offshore Products
has leveraged its knowledge of molded thermoset composites and elastomers to
help meet this demand. For example, we have had success in developing and producing
composite drillable zonal isolation tools (i.e., bridge / frac plugs) utilizing
design and production techniques that reduce cost while still delivering high
quality performance. Time to drill out has been reduced significantly in comparison
to other filament wound products in the market. Our products also include:
Swab Cups - used primarily in well servicing work;
Rod Guides/Centralizers - used in both drilling and production for pipe protection;
Gate Valve and Butterfly Valve Seats – we service many markets in the
valve industry including well completion, refining, and distribution;
Casing and Cementing Products – we are a custom manufacturer of cementing
plugs, well bore wipers, valve assemblies, combination plugs, specialty seals
and gaskets; and
Service Tools – our products include frac balls, packer elements, zonal
isolation tools, as well as many custom molded products used in the well servicing
industry.
Other Products & Services. Our Offshore Products segment also produces a
variety of products for use in industrial, military and other applications outside
the oil and gas industry. For example, we provide:
sound and vibration isolation equipment for marine vessels;
metal-elastomeric FlexJoint® bearings used in a variety of naval and marine
applications; and
drum-clutches and brakes for heavy-duty power transmission in the mining, paper,
logging and marine industries.
