World Oilfield Forum
Hi, I am a new member. Am a geologist but do not know a lot about oil drilling mechanics, but been studying it. Am mostly an inventor and have had success at that, mostly in software biz.
On the DH spill, the initial attempts related to trying to plug it off or capture within a pressure pipe. This failed miserably making the spill much worse, some think it was only 1,000 bopd before the fixes were attempted.
Since then is anyone aware of a new technology to deal with capturing the oil at the point of the leak? The mistakes were bad ones, but 10-20 years from now it will happen again. I have filed a patent based on the concept of not disturbing the equipment at the seafloor where the leak is happening, but basically suction dredging all the escaping oil at the source (even if at 5,000') and dealing with the methane hydrates that might form.
Have any of you heard of any new technologies to capture oil spills at the underwater source?
Hi there,
A DISASTER that DID NOT need to happen.
YES, the methods used to contain the DWH leak were too late.
The eventual methods and ideas had been suggested on Day 2.
Methods of recovery of the 'spilt' substances had also been suggested on Day 2.
ALL these methods had been rejected by the 'people who thought they knew better'.
We suggested using 'Deep water mining' equipment, that has been available way before Macondo for mining minerals in the DEEPEST waters on this planet.
A small modification and you have the 'vacuum' cleaner required for 'cleaning' the seabed.
The surface equipment that was 'claimed' to be required to process and separate the recovered products had been available.

I will contact you at your email too. Thanks for that feedback. I have designed and fabricated several gold suction dredges up to VW engine powered ones, and used them. My photo is about a mile from where have used some of them. Very much like the Discover Channel new show about Nome dregders.
How I got involved was for nearly two months expected then to solve it, then could not take it any longer, stopped another project and came up with a solution, based on my suction dredging design experience. I contacted BP and Coast Guard could never even get a response, so wrote a patent so something would be in place for the next spill.
The biggest problem is the methane hydrates at bottom and dealing with the air lift effect as the gas does phase shift then expands rapidly on ascent. Both problems are solved. Am sure it will work, and have to say can not think of any invention have come up with, that did not work in the real world. If you know of anyone that is good at CFD (computational fluid dynamics) software and wants to be part of getting this implemented, please let know. With CFD it can be proved that it will work, no need to build a prototype.
So to the lest of your knowledge, if we had another DWH tommorow, they would be trying to recover only part of it on surface as opposed to 100% at source?
Thanks for you input! Dana
HI DANA From Colombia south america. Want to join to your tests. REcentl in Colombia will start the next seabed drilling wave and we want to share information regarding the protection you are talking. Also the dredging system how could be offered to the drillers?

The system has been designed and patent application has been filed, but the apparatus has not been built yet. It involves something similar to to a harbor suction dredger or a suction dredge such as Mel Fisher used for recovering gold coins and canon balls from sunken Spanish Galleons, but has several unique aspects just for oil spill recovery underwater at the source before the oil can cause damage and be lost.
On DHW spill BP's main expense by far was the cleanup and damages, but they lost millions in oil too. With this system basically 100% of the oil would end up in a tanker at the surface in addition to the big expense, damages and cleanup being eliminated once the device is barged to the location. The two most important unique aspects in the system is the prevention of methane hydrates at the nozzle and the ability to prevent (when Nat Gas is present as it was at DHW) the upper portion of the conduit to surface from becoming 99% gas not liquid as bubbles expand rapidly. If the conduit becomes mostly gas, not liquid, the result would be a crushing of conduit and extreme vacuum at the leak source at the bottom.
The solution was devised after the DHW spill occurred. I would be glad to talk to you more. If you could tell me more about your company and needs for underwater oil/gas spill recovery at the source, can better answer your question. You can contact me directly at Dana@SeqnTech.com
Thanks, Dana
