“…A thermally stable acrylamide-based polymer with a reduced polymer loading of 30-40% less than guar-based fracturing fluid was considered to minimize formation damage concerns. With a polymer loading of 3 kg/m 3 , the fluid viscosity stayed above 300 mPa•s at 100 s −1 shear rate for 2 h at 143.3 • C [50].…”

“…While this may still be acceptable, the major limitation of these systems is the additional loss of needed fracture length [43]. For high temperature wells, guar-based fracturing fluids need to be formulated with higher polymer loading and at a high pH, that leaves insoluble residue and a tendency to form scales with divalent ions [50]. A thermally stable acrylamide-based polymer with a reduced polymer loading of 30-40% less than guar-based fracturing fluid was considered to minimize formation damage concerns.…”

Hydraulic fracturing operations are performed to enhance well performance and to achieve economic success from improved production rates and the ultimate reserve recovery. To achieve these goals, fracturing fluid is pumped into the well at rates and pressures that result in the creation of a hydraulic fracture. Fracturing fluid selection presents the main requirement for the successful performance of hydraulic fracturing. The selected fracturing fluid should create a fracture with sufficient width and length for proppant placement and should carry the proppant from the surface to the created fracture. To accomplish all those demands, additives are added in fluids to adjust their properties. This paper describes the classification of fracturing fluids, additives for the adjustment of fluid properties and the requirements for fluid selection. Furthermore, laboratory tests of fracturing fluid, fracture stimulation design steps are presented in the paper, as well as a few examples of fracturing fluids used in Croatia with case studies and finally, hydraulic fracturing performance and post-frac well production results. The total gas production was increased by 43% and condensate production by 106% in selected wells including wellhead pressure, which allowed for a longer production well life.

Guar gum and its derivatives based fracturing fluids are most commonly used in hydraulic fracturing. For high temperature wells, guar-based fracturing fluids need to be formulated with higher polymer loading and at high pH that leaves insoluble residue and tendency to form scales with divalent ions. In this paper, newly developed reduced polymer loaded fracturing fluids based acrylamide polymer was deployed from lab developments to field implementation. A thermally stable acrylamide-based polymer with a reduced polymer loading of 30-40% less than guar-based fracturing fluid was considered to minimize formation damage concerns. The crosslinked fracturing fluid viscosity was optimized at 340°F, bottomhole static temperature, and 315, 290, 265 and 240°F cooldown temperatures using a high pressure high temperature (HPHT) rheometer. For successful field deployment, a novel reduced polymer fracturing fluid was evaluated in the following sequence: chemical management, quality control, optimization of fracturing fluid formulations with field water, field mixing procedure, on-site QA/QC, data frac analysis and execution of main treatment. This paper presents rheological studies of reduced polymer loaded fracturing fluids at bottom hole static temperature (BHST) and cool down temperatures of selected well candidates that demonstrate the superior thermal stability of this novel fracturing fluid. With a polymer loading of 35 lb/1000 gal, the fluid viscosity stayed above 300 cP at 100 1/s shear rate for 60 min at 340°F. The fracturing fluid formulations were optimized using both live and encapsulated breakers using high pressure and high temperature rheometer. Due to the fast hydration of the base polymer, the linear gel was mixed on-the-flying during the main fracturing treatment. The main fracturing treatment was successfully executed with a 40 barrels per minute (bbl/min) pumping rate with increased proppant concentration up to 4.5 pounds per gallon (ppa) using 40/70 HSP (high strength proppant) proppant. The fracturing fluid system based on the novel acrylamide copolymer offers advantages over guar-based fracturing fluid such as low polymer loading, excellent high temperature stability and less formation damage. This paper presents a systematic approach and lessons learnt during novel fracturing fluid deployment.

Chemistry and the materials portfolio play a central role in fracturing success. Challenges in a achieving successful and productive proppant pack are resolved using varying products and fit-for-purpose chemistry utilization. The conventional understanding of using fluid loss additive (FLA) only for reducing fluid leakoff in high-permeability formations can be extended with advanced digital tools for optimum realization of a broader application spectrum for well-specific challenges. Polylactic acid-based powdered degradable FLA (DFLA) was developed with engineered particle size distribution to plug rock pore throats. Core flow tests were conducted with and without DFLA with borate crosslinked base fluid to measure the performance metrics. The application spectrum was extended beyond the fluid loss control in high-permeability rock to aid in screening out multiple fractures and natural fractures, reducing poroelastic tendency of tight, tectonically influenced formations. An advanced numerical modeling simulation approach was used to evaluate the distribution of the DFLA particles along the fracture cross-section and their dynamics to yield optimum fracture geometry with lesser pad volume. Coreflood tests demonstrated a reduction of up to 40% in fluid loss coefficient and spurt loss components with 30 lbm/1,000 gal DFLA loading. A regained permeability reduction of 12% from the baseline was observed when 25% particulate DFLA mass loss occurred, which can be minimized with higher shut-in times and complete degradation. The spectrum was expanded conceptually for up to eight applications based on literature references. Digitally advanced hydrodynamics and an in situ kinetics simulator were used to accurately model the slurry flow with and without DFLA. The model was extended with a sensitivity study with 32 synthetic cases to extend FLA utilization to medium- and low-efficiency formations. The modeling results showed that more than 50% of crosslinked pad volume could be saved while retaining the same fracture geometry evolution. Industry use of FLA chemistry has been minimal. In the digital age, this is the first and a unique demonstration of how digital tools can aid extending the material portfolio spectrum investigated from laboratory, simulation, and field case perspectives. Multiple applications of FLA can enhance project economics and reduce polymer and fracturing fluid formation damage by lowering the difference between differential pressure at the fracture face and drawdown during cleanup and the production phase.
