Nanotechnology, the study of manipulating matter on an atomic or molecular scale
and developing materials, devices or structures possessing nanomaterials, has
been used in the medical, automotive, aerospace and textile industries.
Now, oil and gas companies are seeking to apply nanotechnology to enhance products
and tools used in oil and gas, including hydraulic fracturing, where the growing
number of zones typically fractured pushes the performance limits of fraccing
applications.
While some technology applications such as nano-robotics might be a pipe dream,
oil and gas companies are now looking at nanotechnology applications for material
science to push the constraints that heavier, bulkier structures and tools put
on oil and gas exploration and production and to address rising oil and gas exploration
and production costs, said Matt Bell, president and CEO of GEODyanmics, a Millsap,
Texas-based developer of perforating technologies.
Besides shale gas proppants, where nano-size pores require proppants to more
efficiently produce hydrocarbons, nanotechnology can increase the strength to
weight ratio of tubulars, and prevent abrasion and corrosion of equipment with
coatings and alloys developed from nanotechnology.
One example is Saudi Aramco. The Company is pursuing nanotechnology applications
for use in reservoir agents. "We want single, effective, scalable solutions that
we can take to the field as quickly as possible," said Howard Schmidt, nanotechnologist
at Saudi Aramco. Fluorescence A. Dots, which are used to map well connectivity
and allow Saudi Aramco to know what injector well is contributing water. Magnetic
nano-mappers have also been field tested on a small scale, with larger scale field
tests to be conducted late in 2012.
Another is Baker Hughes Company. Its FracPoint system, a multi-stage completion
system that uses openhole packers to isolate multiple stages and ball-activated
sleeves to divert frac treatments, now features IN-TALLIC disintegrating frac
balls, which are made of a new nanomaterial developed by the company's nanotechnology
scientists.
Of course, oil and gas companies also must be willing to invest in research and
development into new technologies. "We make progress in R&D, but then we eat
our own young," said Bell "We need entrepreneurs who are willing to invest and
get nanotechnology from the research institutes to commercial application."
