Abstract:
Multi Stage Stimulation (MSS) is an established and growing market in Oil & Gas. The goal of this product line is temporarily isolation of sections of a well to perform sequential stimulations (hydraulic fracturing). This has been primarily used in “Unconventional” reservoirs such as shale plays and tight gas, the majority of which are horizontal wells. For cemented applications, isolation is currently achieved using primarily Frac-plugs or Bridge-plugs. Innovations to revolutionize this market are the new developments of a class of water reactive or degradable alloys. Novel processing routes have been adopted to transform these dissolvable materials into high strength bulk nanostructured alloys and have been adopted for Schlumberger’s MSS Product line, into the Infinity Plug and Perf System*. The system is essentially it is a valve in the shape of a ball made of the degradable material, deployed on a seat or profile with the ability to hold 10,000 psi [69 MPa] pressure differential during stimulation (fracking) can replace Frac-plugs and reduce intervention time to remove the barrier to entry for the next stage. This ball valve then degrades over time in contact with water based well fluids. Applications of novel processing routes to engineer high strength nanostructured degradable alloys with tailor-able well fluid reactivity have opened a variety of applications in oilfield services. Our presentation will introduce MSS as a topic for general interest and discuss salient technological developments in innovative nano-materials and mechanical design.
