Location: San Diego Marriott Marquis Hotel; Room Carlsbad
Abstract: Advent of water reactive or dissolvable materials and nanostructured alloys, enabling engineering of high strength, corrosion resistant structural materials with tailored specific gravity and with an intelligent combination of micro-electro-mechanical system (MEMS) sensor devices, mechanism to assess “Corrosion and Environmentally Assisted Cracking (EAC)” of oilfield alloys under live reservoir conditions is now possible. Our sensors facilitate testing at the production zone and not in a simulated autoclave environment, providing much needed data to make judicious materials selection for target environment without assumptions and extrapolations. Here we present method to deploy retrievable sensor packages in wellbore, wherein the gauge carrier is (1) made from bulk nanomaterial (2) has tailored specific gravity (3) ultra-high strength; as such can withstand greater than 10,000 psi collapse with wall thickness of ~ 1mm (4) can be corrosion resistant (stemming from customer requirement) (5) allows the retrieval of the sensor package aided by buoyant forces.
Tracer Impregnated nc-materials and Dissolvable Solids for Controlled & Bulk Release Machinable into Downhole Tools for Sensing and Characterization

Abstract: Water and oil soluble tracers, wherein tracer material is a nc-powder or liquid are often used in oilfield for sensing and reservoir characterization. Many attempts have been made to integrate tracers in light weight high strength nc-materials and dissolvable alloys, however unsuccessfully. Here we present our novel approach to include tracers, including quantum dots on silica substrates and nano-electronics into the DNA of nc-alloys and dissolvable materials. Mechanisms encompass matrix mixing and impregnating, in a permeable and porous dissolvable scaffold for controlled & bulk release as well as downhole characterization. Applications are many-fold. Tracer impregnated nc-materials and dissolvable solids can be of any shape or form, for example ball for packers to isolate zones; rings deployed anywhere in a wellbore or proppants to be blended with conventional particulates and injected in the formation. Tracers released from such alloys on reaction with deployed environments can be made to act as timers.
