F.1. Well Abandonment and Plugging solutions – Well & Rigless entry

Issues:

The key to a successful well plugging and rigless well abandonment is the use of seals that will secure the well long after the abandonment is complete, reducing corporate liability and potential environmental impact. Traditionally elastomer and cement plugs have been used with varying degrees of success and reliability. Due to their material construction they may deteriorate over time, particularly in corrosive environments. Conventional bridge plugs also have very small expansion ratios, limiting their use to wells with restrictions. High expansion plugs, such as inflatable packers, don’t possess the differential pressure capabilities required for many oil well abandonments, nor do they provide a gas tight seal.

Solutions:

With our patented Wel-lok M2M™ technology, we have developed multiple tools for use in plugging and abandonment of oil and gas wells. These tools are known as the Wel-lok M2M TS™ (Tubing Seal) and Wel-lok M2M MXD™ (Maximum Drift). Both tools offer higher expansion ratios than conventional bridge plugs and higher differential pressure ratings than inflatable packers, all while providing a V0 rated, gas tight seal that cement cannot provide. Though their designs are different, the proven BiSN technology behind them is the same.

F.2. Facilities, pipeline & flowline (Oil & Gas) abandonment solutions 

The oil, gas and LNG industry are growing exponentially as demand for energy increases worldwide. Activities in well-abandonment, facilities, pipeline, and platform-decommissioning operations will increase simultaneously. 

Pipeline decommissioning and abandonment are conducted for two main reasons: A pipeline has reached the end of its useful lifespan and further use is no longer economically viable. The oil and gas reserves it serves has been exhausted and as such, there is no longer a product for conveyance. Same may be the case for facilities. Technically sound well-abandonment practices are essential for long-term environmental protection, especially as regulations become more stringent and complex. Although advanced technologies and techniques bring new meaning to the “permanent” aspects of abandonment work, operators seek to minimize abandonment and decommissioning costs because these expenses are not recouped.
