Remove Your Risk with SAS Breaker Products

Calling all oil operators - why pay the price for inadequate product development? By using SAS Filtercake Breaker Products you could remove the uncertainty of using bespoke formulations that have proven in the past to be difficult and risky. Here's how...

We all know microemulsions can be fragile and fickle chemistries – especially where environmental variables such as pH, salt concentrations and temperature are concerned. Indeed, some of these environmental variables have been studied in great detail in order to maximize efficiencies of microemulsion products for use in the field - adjusting for salinity effects for EOR applications for example.

Since microemulsions are so specific in their requirements it has been hugely challenging for chemical providers and service companies alike to formulate products that perform beyond these boundaries and limitations – specifically where these variables have such a range from surface pumping to downhole well conditions.

From a pragmatic perspective huge risks, costs and logistical problems arise from having to overcome these issues. Simply blending a treatment pill sufficiently for downhole use, in itself, may be a huge obstacle if the formulation is not stable. It may take excessive work and time on the rig site to try and solubilize a chemistry in particular brines with significant equipment and manpower requirements.

Once solubilized some products have to be deployed into the well within a matter of hours in order to be effective and to avoid having these formulations fall apart and break down. If engineering malfunctions or other delays happen at this point, then the operator may end up paying the bill for hundreds of thousands of dollars in wasted chemical - paying a second time for a fresh batch to be made up after the obstacle to deployment has been overcome.

Then there is the risk of what happens downhole when the conditions (and especially the temperature) may change. Is it really worth taking that risk? We have an alternative!

SAS Production Services Breaker products are fully and readily soluble in brines meaning simple and straight forward preparations - needing less equipment and fewer personnel due to brine compatibility. Our Breakers are also stable over time so any on site delays do not mean wasted cash and chemical – no need for new batches to be made and for hundreds of thousands of dollars to be discharged.

Finally, SASPS Breakers are both robust and temperature stable so they perform every time downhole. What's not to like? Don't take the risk of using bespoke formulations. Use the best. Use SAS Breakers.

How to Return a Well to the Original Permeability and Increase Production

There is less need to drill more wells when existing wells can be completely remediated. It is possible to realise a return to original permeability and experience up to 600% production improvement. SAS Filtercake Removal & Breaker products allow for either drilling fewer wells or the option to remediate existing wells to meet your field development plan and production target. You can double, triple or quadruple your return on investment through the application of our technology while halving the number of planned wells or workovers.

SAS Breaker products are superior in the following attributes:

1. Off the shelf suite of products can be quickly deployed no matter what your application is – no requirement for extensive lab customization, just some quick compatibility tests.

2. Single pill train with a one can application – minimize rig pumping time and equipment required, does not require viscous pills to remain intact while deploying.

3. Phase stable – when applied they will not separate and remain fully effective for extended periods of time.

4. Simple preparation and mixing, no shearing required – just add the solution to the brine of your requirements.

5. Can be designed to be instantaneous active or delayed action.

6. Can be utilized with Mono or Duo Valent Brines with zero detrimental effect.

7. Do not require temperature to activate and completely thermodynamically stable.

8. Extremely efficient diffusion where it water wets and coats all solids.

9. Breaks all in-situ emulsion blocks.

10. In-situ acid generators will solubilize all Calcium Carbonate base filtercakes.

11. Creates fluidity and full mobilization of filter cake solids and all fines.

12. Smaller delta-P in producers and injectors resulting in substantially reduced reservoir damage.

SAS Products Effectively Clean-Up OBM Filtercake

One of our customers in West Africa put our Filtercake Removal & Breaker Products to the test, carrying out a laboratory evaluation to test their effectiveness on oil based mud (OBM) filtercake clean-up. Two products were chosen for this experiment, the SAS Breaker F and the SAS Breaker 162B. The aim was to simulate the effectiveness of each of these products on the dissolution and cleanup of filtercake formed by drilling fluid.

---

Test Parameters...     

• BHST - 200 F (93oC)

• Pressure - 200 Psi

• Brine - KCL weighted to 9.5 ppg

• Duration - 24 hours shut in period

---

The results...

In the first test we used:

Breaker F: 7.5% by volume - 0.075bbl/bbl

Breaker 162B: 8% by volume - 0.08bbl/bbl

This combination completely dissolved the filter and there was no residual carbonate left on the filtercake after application (pictured below).

In the second test we used:

Breaker F: 10% by volume - 0.1bbl/bbl

Breaker 162B: 8% by volume - 0.08bbl/bbl

This approach was also successful in completely dissolving the filter, leaving no residual carbonate on the filtercake (pictured below).

We always provide our customers with successful results, and we can do this for you too. SAS keep costs down and get production up, so why not contact us today!

SAS Filtercake Removal West Africa Lab Study

SAS Breaker Filtercake Removal Products are suitable for oil based mud (OBM) based on synthetics, oil and esters containing calcium carbonate. The unique SAS products are robust and work with any OBM or brine type and quickly solubilize the oil from the drilling mud – no need for bespoke formulation.

A great example of the SAS Breaker 162SC at work comes from a Lab Study (which can be downloaded here) we done for one of our customers in West Africa. In the picture on the left is the untreated OBM cake. In this case we treated the filtercake with a combination of SAS Breaker 162SC and SAS Breaker F (formic acid generating). Both products were used at 10% concentration.

Perfectly solubilised in a monovalent brine and using a 24-hour soak at 200F (93C) the SAS Breaker products achieved almost complete removal.

We can do this for you on your producing or injector wells. We keep costs down and get production up! So why not contact us today to find out more!  

SAS Breaker Products Put to the Test in India

Our customer, based in Asia, was experiencing difficulty in meeting production expectations from new wells. They drilled using Oil Based Muds (OBM) in a heavy oil reservoir. They were using thermal stimulation in order to decrease the viscosity of the oil. However, no mud damage treatment had been used before activating the well and they were not producing the expected volumes. SAS Production Services knew that our products could help. 

The operator was aware that the drill-in fluid damage was significant and beyond the capabilities of their usual treatment methods. Many lab tests were conducted and the SAS Breaker products were a clear winner, outperforming the other potential solutions being considered.

SAS Breaker treatment fluid was used to dissolve and displace the OBM used to drill the wells. The operator decided to use remedial treatments based on displacing SAS Breaker for OBM fluid into the screens spanning the reservoir sections, using coiled tubing.

SAS Breaker products are a patented approach using unique microemulsions to mobilize hydrocarbons in the skin created by the OBM. SAS Breaker products can be combined with most available acids and acid precursor products. This aids to dissolve calcium carbonate that is often found in OBM and filtercake. The fluid was placed in each well using coiled tubing and left downhole for the required soak period. The wells were then returned to production.
