Weatherford provides premium quality products and services without compromising the health and safety of its workforce or its customers. Committed to protecting the integrity of all its resources, Weatherford strictly complies with all safety and environmental laws and regulations. Health and safety is a top priority, company-wide policy that is strictly enforced. Weatherford also continually seeks and adopts environmentally responsible work practices, services and materials to promote a safe and environmentally responsible work environment.

Completion Flow Control

Flow Control is the ability to regulate or prevent the flow of fluids or gases in the wellbore, and flow controls are the devices used to perform those functions. Flow control is required throughout the life of the well:  At the initial completion  During the producing /injection life

of the well

 Whenever wellbore intervention is

required  At workover time

The flow control process is often underestimated, and flow control design frequently under-engineered, leading to unnecessarily costly intervention operations. Weatherford Completion Services offers a very wide range of flow control products backed by the operational expertise necessary to ensure that flow control selection reflects the needs of the well throughout its life cycle, and not just at completion time.

Flow Regulation Flow controls are used to regulate or prevent flow, during the operational life of the well, often for very long periods. These include:  Zone isolation  Reducing or increasing production or

injection flow

 Safety systems safety valves or injection

valves

 Fluid loss control

Flow regulation devices require the twin virtues of long term reliability and simplicity of operation. Pressure Testing Flow controls are used for all wellbore pressure testing to:  Confirm the integrity of completion and

its components

 Confirm the integrity of XMAS Trees  Set packers

Barriers Many flow controls are barriers to flow in the wellbore. They can be either bidirectional or uni-directional and in some cases both. Flow control barriers are used for:     

Under-balanced completion Well suspension Zone plugging Safe removal of XMAS trees or BOP's Recovery of upper completions during workover

Flow control barriers must be designed to withstand all potential hazards.

Weatherford Flow Control Structure

Weatherford Flow Control Structure Weatherford divides the Flow Control product line in the following groups: Interventionless Completion Products Weatherford Interventionless Completion Products system is a grouping of tools which perform Flow Control functions (barriers, fluid loss control, packer setting) without the need for a specific intervention in the well bore on wireline, coil tubing or other means. Slickplug The Weatherford Slickplug is a retrievable bridge plug deployed and retrieved on slickline, or other intervention means that do not require explosive or pyrotechnic setting tools.

Sliding sleeves Weatherford Sliding sleeves are tubing mounted devices which regulate flow from or into individual producing zones, or to control communication between the tubing and the annulus. Standard flow controls Weatherford Standard Flow Controls comprise a wide range of industry standard flow control devices, including nipples, lock mandrels, plugs, standing valves and every accessory for those items. Standard Flow Controls are the appropriate choice for conventional, economical, flow control requirements. Uniset flow controls The Weatherford Uniset System is a high performance, high pressure, premium flow control system to suit exacting completion architecture.
