Casco’s FR-1002 is a nano-composited, nonionic, high performance friction reducer that is designed specifically for hydraulic fracturing. In contrast to other friction reducers, FR-1002 has the following characteristics:
- Unlimited salinity resistance
- Handles extremely harsh brines containing saturated levels of Ca, Mg and Fe.
- 100% biodegradable, green friction reducer.
- Water soluble, does not block the formation or cause damage to the formation like conventional friction reducers.
- Compatible with common fracking fluid ingredients.
- Can also be used in deep well applications to increase flow and decrease pump pressure.

Case History 2
Well Clean Out via Coiled Tubing
Field: Sichuan Basin, P.R.C.
Operation: Comparative clean-out via coiled tubing by utilizing FR1002 vs a conventional dry powder friction reducer (abbreviated as “FR-A”).
Results: The use of FR1002 led to up to 20% lower pumping pressure than conventional dry powder FR (FR-A) (see Figure 1 below).
- When pumping rate was 0.2-0.3 m3/min (53-80 gallons/min), the two friction reducers made no significant difference
- With pumping rate increased to 0.55 m3/min (145 gallons/min), the pump pressure was 11MPa (1,595 psi) when using FR-1002 and 14MPa (2,031 psi) when using FR-A
- The gap (difference in pump pressure) increased further with the increase of pumping rate (greater than 0.55 m3/min or 145 gallons/min)

Case History 3
Horizontal Fracturing/Same Well, Same Stage
Field: Sichuan Basin, P.R.C.
Operation: Comparative fracturing on the same stage utilizing FR-1002 vs a conventional dry powder friction reducer (FR-A).
Results: Use of FR-1002 has achieved 10% pumping pressure reduction than conventional dry powder friction reducer (FR-A) (see Figure 2 below).
- Pumping rate: 12 m3/min (3,170 gallons/min or 75.6 bbl./min)
- Lowest pump pressure of 52MPa (7,542 psi) achieved when using FR-2
- Before/after FR-1002, average pump pressure was 57.4MPa (8,325 psi) & 54MPa (7,832 psi) respectively
- A pumping pressure reduction of up to 10% using FR-1002

Case History 4
Horizontal Fracturing/Same Well, Different Stages
Field: Southwest China
Operation: Comparative fracturing on different stages of the same well utilizing FR-1002 & a conventional emulsion friction reducer.
Results: The use of FR-1002 led to additional 8% pumping pressure reduction than conventional emulsion friction reducer (see Figure 3 below).
- Pumping rate: 11 m3/min (69.2 bbl./min)
- An additional pumping pressure reduction of 8% by FR1002 was the result
Case History 5
Daily Gas Production Enhancement
Field: Sichuan Basin, P.R.C.
Operation: Comparative daily gas production through two wells on the same platform [one fractured by FR1002 (Gas Well #1); the other by a conventional inverse emulsion FR (Gas Well #2)] (see Figure 4 below).
Results: FR1002 is three times more effective at curtailing daily gas production decline than conventional inverse emulsion FR.
- Gas well #1: decline rate was ca. 10% after three months of production
- Gas well #2: decline rate was ca. 30% after three months of production
- Literature reports ca. 30% decline after three months of gas production on 838 wells (see image to the left in Figure 4)
