Shale Gas and Shale Oil refer to resources which are trapped into a shale formation.
Horizontal drilling and hydraulic fracturing techniques have made these unconventional resources accessible, and they can now be exploited.
Tight Gas and Tight Oil are mostly classic sand deposits; however the oil and gas are trapped in rocks with low permeability (i.e. little or no connection between pores, which sharply curbs or even prevents the circulation of hydrocarbons).
Vallourec provides solutions to critical unconventional wells to minimize the risks to operators.
Shale gas/oil and tight gas/oil wells have their own unique challenges that require experienced partners to provide guidance on the solutions available.
Shale and tight sand formations require fracturing to release trapped hydrocarbons. As fracturing technology progresses, connections are subject to higher fracturing pressures, and a greater number of high density fracturing stages.
With the increasing number of horizontal wells, operators require validated connections and quality OCTG pipes able to sustain greater tension, compression, and torsion over the life span of the well.
Those challenges can lead to severe consequences on the OCTG including:
Pipes getting stuck in the well
Tight spots and deviated wells
Subsidence and compaction during the running process
Thermal expansion during well fracturing
Vallourec works with their clients to understand the challenges they are facing in their shale and tight sand wells in order to find appropriate solutions.
To be able to provide suitable answers to the Shale and tight challenges, constant development of products, testing, manufacturing and services is ongoing within Vallourec including:
Semi-flush connections VAM® SFC and VAM® SG with enhanced torque and tension resistance.
VAM® TOP HT and VAM® 21 HT for superior gas tight sealing plus rotational torque and bending capability.
VAM® EDGE SF the next generation high torque semi-flush connection with industry leading technology representing twice the torque capacity of the current market solution.
Testing for purpose is a key for successful operations providing you with quality assurance
