Since there is a possibility that the future could bring issues concerning offshore fracking, here is some of the information about it:

Will the Gulf of Mexico remain a dumping ground for offshore fracking waste?

When you think of a fracking site, the image that comes to mind is probably a bare-scraped well pad in a rural or maybe suburban landscape, topped with a drilling rig and other industrial infrastructure, and a fleet of trucks to haul materials needed for the controversial process that involves high-pressure injection of fluids into wells to boost oil and gas flow.

But nowadays fracking is also happening in a landscape of a very different sort: the Gulf of Mexico. …

Offshore Hydraulic Fracturing Q&A

1. Is offshore hydraulic fracturing the same procedure as operations conducted onshore?
The basic operation of hydraulic fracturing is similar but the scale is significantly different than onshore
operations due in large part to the geologic formations and the cost and logistical constraints that occur
with offshore platforms. Typical water usage for offshore hydraulic fracturing is 2% of the liquids that is
used routinely for onshore hydraulic fracturing (like those used in the Marcellus shale play, for example). …

OFFSHORE SAND CONTROL AND WELL STIMULATION TECHNOLOGY

Abstract:

Offshore, a form of sand control technology has been in commercial use since the early 1990’s. Offshore sand control technology combines two mature oil and gas technologies – hydraulic fracturing and gravel pack completions. The result has been a significant improvement in well life and reliability, productivity, and oil and gas recovery.

In many offshore regions, the geologic formations that produce oil and gas are unconsolidated, which means the sand that makes up these formations is loose or poorly bonded, much like the sand on a beach. As a result, this loose sand can end up inside the production piping in the well or production equipment on the surface. Sand production is highly undesirable since it can plug pipes and equipment, erode piping (much like sand blasting) and lead to corrosion of pipe and equipment. Eliminating sand production has been one of the main production challenges faced by engineers since the early days of offshore oil and gas development.

Offshore fracking – SourceWatch

Fracking for offshore oil and gas reserves is taking place in the United States. In California, Venoco is currently fracking the Sockeye field offshore from McGrath Beach in Santa Barbara County. Critics have argued that there needs to be more regulations and public oversight of these practices.[1]

Fracking also takes place off the coast of Long Beach, California on man-made oil islands. It was reported in 2013 that 203 fracking operations had taken place offshore Long Beach at six different sites over the past 20 years.[2
