Too early in morning, should read "thin sands" not "shallow sands"...
Hiya Voskos....no problem in posting, have been in contact with Sandjet for quite a while, always get informative answers to any questions posed...oh and I'm definitely a bloke :)..
Additional reply received this week.also posted on Reddit this morning.
Questions were.
How would they get Sandjet to deal with "formation damage" and how accurate can they be for targeting small areas of interest(shallow sands)
Typically the timescale is the adjustment that we make to go farther into the formation. By lengthening the time on station, we are delivering more sand to cut perforation tunnel, which is the goal. That is one of the big advantages over explosives- the explosive perforating gun is limited in the amount of explosive charge that can be loaded into it based on its size. Since we are conveying cutting energy from the surface, we can continue to send that cutting energy in the form of pressurized sand slurry for as long as we want. At some point, there are diminishing returns on that time of course, but when we know there are near wellbore damage problems, extra cutting time/sand will extend the perforation tunnel and hopefully get us past the damage. The second adjustment might be to increase the pressure at the tool a little. Our typical target pressure at the tool is 2,500 psi, when we know there are problems to overcome, sometimes we will increase the pressure (by increasing flow rate) to 3,000 psi. The challenge here is that increasing beyond 3,000 psi will shorten the amount of pump time we can get before it is time to come out of the well and put in fresh jets so we have to strike a balance there.
Depth control can be achieved a few different ways. The easiest way is to have something in the well that the tool can “tag” to verify depth measurement. This might be a plug that has been set for that purpose, the bottom of the well (if perfs are relatively close to the bottom), or some nipple or restriction that have been placed for that purpose. The second way would be running a wireline tool inside the workstring to the tool and verify current depth of tool. This would apply if we are running the tool on tubing large enough to allow the tool to run in it."

Additional Sandjet (Td) reply .
I asked how much water is used for the aforementioned 100lb per perforation (30lb to clear casing, 20lb to clear cement, 50 lbs to create formation in the "tunnel" also asked was it reused...2nd question was "how does it compare with explosive perforation....depth of perforation etc...
Reply below
Q1 Answer "Our typical concentration is ½ pound of sand per gallon of water (60 kg/m³) so 100lb of sand would mix with 200 gallons of water (45 kg of sand would mix with 0.75 m³ of water). We have some customers that reuse the water/gel portion of the slurry by pumping the return fluid into a tank or two which allows the sand to settle and they draw the fluid from the top of the tank for reuse. It often depends on the setup at the well- for example, if they are going to perform a hydraulic fracturing operation afterward, our amount of fluid produced is easily handled without recycling. However if this is an older producing well, infrastructure might not exist for water disposal and reuse might be a significant advantage. Also, the gel is typically plant based (guar or xanthan) so the return fluid is environmentally friendly with the exception of whatever formation fluid might be circulating back with the sand slurry.
Q2 answer"Typically, the length of perforation is more than comparable explosives, but at a minimum, equal in length. The real advantage for sand jet perforating (SJP) is that the diameter of the tunnel increases with distance from the casing, while explosive perforations decrease in diameter with distance. For example, a 0.5” hole size in the casing is very common for both SJP and explosives. In the SJP tunnel the diameter increases in size from 1” to 2” in diameter at the end of the tunnel. In the case of explosives, 0.5” is as large as the tunnel will ever be and it decreases in diameter from there. When calculating contact area to the formation of the larger SJP perf tunnel there is often a factor of 10x more contact. This makes SJP especially attractive in hard or tight formations. Below is a graphic that we are using in a technical paper that we are presenting at the Society of Petroleum Engineers Annual Technical Conference in October that you might find interesting as it compares the two perforation tunnels."
Seeing as it's a quiet day, decided to break my silence on here and post on here what I posted on Reddit the other day.
Just for interest( Sandjetting).
I e mailed "sandjet td tools" enquiring how the process worked...(getting the mud out whilst jetting, and how they know that perforation has occurred.
May i add, i did not mention Predator or Morocco in the e mail..gives a good insight into the processes used 😀
Reply below .
Thanks for your email and interest in the process. When we begin pumping sand slurry to the tool, the wellbore will be full or nearly full of fluid (depending on if we are using coiled tubing or jointed pipe as the work string/fluid conveyor). As we pump the sand slurry through the tool to create the perforation tunnel, the bulk of the used slurry will flow to the surface and into a containment area. The sand slurry consists of water, sand, and a gel used to increase sand carrying capacity of the fluid. The gel allows us to more easily return the sand to the surface. There will be a little sand left in the well after the perforating job, and typically the tool is run back into the well to circulate/wash out the portion that might have fallen below the tool.
To your second question, the sand in the sand slurry performs the cutting and perforating work. We know the amount of sand required to perforate casings of different sizes, cement, and formations from 15 years of surface testing and well perforation. A typical perforation tunnel will require approximately 100 pounds of sand per tunnel. Unconsolidated formations may require less and more challenging environments like multiple casing strings will require more. Using the 100 pound example, approximately 30 pounds of sand are required to perforate the casing, 20 pounds to perforate the cement, and the 50 pounds remaining are for creating the perforation tunnel in the formation. We have been able to verify these quantities on well locations by performing injection tests to document that the wellbore has communication with the formation/reservoir.
I hope that this information answers your questions. Feel free to send more questions or you are welcome to give me a call.
Thanks and regards,
