The pressure wave valve (PWV) is an intervention free, open-on-demand, equalising device that can be fitted to lock mandrels and bridge plugs to provide a large through-bore once activated.

HOW IT WORKS

With excellent pump-through capability, the system functions purely on a mechanical hydraulic principle. The internal mechanism operates only when it senses a 'wave' of applied pressure i.e. starting from a low pressure range, increasing to an upper pressure, and then returning back to a low pressure. This sequence counts as one 'wave'. By repeating this sequence several times to the pre-set values, the valve will open and provide a large through-bore.

PRODUCT FEATURES

• Intervention-free method of opening a circulation path
• Activation pressure cycles can be minutes or years apart
• Equalising without wireline, reduces intervention runs - saves rig time and reduces risk
• No electrics, batteries or other time-limited components
• No well specific setups required
• Hydrostatically balanced
• Can be fitted to any flow control device
• Modular debris management system

The operation of the valve is non-time dependent. The first two 'waves' can be carried out within minutes of each other and the remainder several months, or even years later.

TECHNICAL FEATURES

• Provides a large through-bore when opened
• Functions purely on a mechanical hydraulic principle
• Activated by sending a 'wave' of applied pressure (low-high-low)
• Different pressure cycle activation ranges available
• Flexible deployment options; Oilenco hybrid plug, lock mandrels or bridge plugs
• Can be pre-installed onshore for completion operations
• Can be retrieved with the tubing during workovers
• No dedicated personnel required on location to operate
• Available for production and annulus bores

APPLICATIONS

• Plug and abandonment (P&A) workscopes
• New completions
• Workovers
