Hydraulic Fracturing Pressure Pumping Spread
We deliver high quality hydraulic fracturing pumping services to customers from the Bakken to the Permian and anywhere in between.
Established in 2012, TOPS Well Services ordered a new fleet of equipment from Stewart & Stevenson and new trucks from Kenworth. This equipment was then hauled to Newton, Kansas, where TOPS´ first well treatment was completed for Petro River Oil Corp.
Since then, TOPS has successfully pumped deep wells with over two-mile laterals to shallow vertical wells while utilizing an inventory of fluid systems ranging from nitrogen and CO2 foam, crosslinks, slickwater and high viscosity friction reducer.

Fracture Modeling Software
Advances in well logging and fracture modeling technology have greatly increased the hydraulic fracturing industry’s ability to predict and optimize fracture designs.
The in-depth rock and fluid properties gathered during well logging gives TOPS the information required to optimize the completion design and accurately estimate how a completion will affect a reservoir system using the advanced modeling software available within our engineering department.
Modern completions modeling software incorporates all complexities involved with geological, geomechanical, and flow considerations to optimize design for reservoir system changes after hydraulic fracturing.
GOHFER Software
GOHFER (Grid Oriented Hydraulic Fracture Extension Replicator) is a multi-disciplinary, integrated geomechanical fracture simulator that incorporates all the tools necessary for conventional and unconventional well completion design, analysis and optimization. A planar 3-D geometry fracture simulator with a fully coupled fluid/solid transport simulator, this software has been continually developed by Dr. Robert D. Barree & Barree & Associates LLC for almost 40 years.
By computing inputs from all disciplines of petroleum engineering, including petrophysics, geology, drilling, reservoir and completions, we get a coherent and consistent three-dimensional reservoir and geomechanical model for both unconventional and conventional reservoirs.
GOHFER has the capability to model multi-layer completions, zipper fracs, and offset depletion effects within multiple wells on the same model while also allowing for pressure diagnostic analysis, production forecasting and rate transient analysis.
FracPro Software
FracPro software improves performance from prospective wells by giving the knowledge necessary to achieve successful stimulations.
Regardless of formation type, permeability or location, using FracPro software can lead to optimized contact area, spacing, EUR, and economic performance. FracPro can effectively model both horizontal and vertical wells in any formation type.
FracPro was the first software to simulate and optimize multiple well zipper completion projects. The software properly sequences and simulates multiple wellbores and high-density network fracture techniques just as they would be done on location.
Pay zones are identified and lithology and in-situ environment of the zone is analyzed. The fracturing design is then written up and simulated to show fracture width, length, and proppant distribution within that zone. FracPro is capable of modeling multiple zones at once as well as real-time modeling during a job.
Laboratory Capabilities
TOPS is outfitted with an industry-focused laboratory facility capable of performing all pre stimulation testing in-house by lab technicians with over 15 years of oilfield experience. With the ability to perform testing in-house 24 hours a day, tests and analyses can be run immediately after receiving samples.
Water Analysis:
Prior to any testing or completion project, a sample of the base water that will be used for the job is obtained and tested thoroughly.
Specific gravity and pH of the sample are measured and give a good initial indication of water quality. Sub ions are then tested using an in-depth procedure, measuring ion levels such as chlorides, sulfates, and carbonates to gauge potential interference and allow for design changes to be made.
Fluid Rheology Equipment:
The TOPS laboratory is equipped with one Chandler Engineering HTHP 5550 Rotational Viscometer and one Brookfield Engineering PVS Rheometer. These tools are used to simulate stimulation process conditions on a benchtop environment.
After water analysis is completed and bottom hole conditions are received for a proposed completion, a prospective fluid system design is created and tested.
Fluid Rheology Testing:
Fluid system samples are tested for both stability and break times using the sample water collected for the job. This testing allows for design changes to be made prior to the job and create a system that will maintain viscosity when carrying proppant but will successfully break down for clean flow back.
Emulsion Testing:
Emulsion most commonly refers to water droplets in a continuous oil phase, which is also called water-in-oil emulsions. Other types of emulsion include oil-in-water and multiple emulsions (e.g. water droplets suspended in oil droplets that in turn are suspended in a continuous water phase).
The formations of emulsions during oil production is a costly problem but can be combatted from the start of completion using a surfactant.
Other Testing Available:
- Bacteria Testing
- Chemical Qualification
- Quality Control Testing
Fluid Systems
High Viscosity Friction Reducer Fluid System:
TVISC-1401 is a high viscosity, polyacrylamide-based fluid system yielding carrying capacity equal to or greater than crosslink systems with superior friction reduction.
Our HVFR system produces higher fluid viscosities with lower friction pressures for excellent proppant transport and regained conductivity, lower stimulation costs, and less wear and tear on fracturing equipment resulting in less down time on site.
When comparing an HVFR system vs. a Crosslink fluid system, cost differences are very apparent, over 60% savings.
Slickwater Fluid Systems:
Slickwater fluids combine high molecular weight polymers with minimal additives to simplify operations, achieve economic goals, and maximize reservoir contact. These polymers are used to reduce fluid friction, enabling efficient and effective service designs that transport proppant with high pump rates rather than the viscosity mechanism of conventional guar linear gel and crosslinked systems.
Base slickwater systems do not require a polymer breaker, yet still produce exceptional post treatment fracture conductivity.
A key advantage of a slickwater fluid system is the simplicity and cleanliness after completion. This system requires no breaker to be pumped with the fluid system to breakdown the fluid for flow back, saving money and time. In a cost analysis of slickwater versus crosslink, chemical savings for a 5600 barrel extended horizontal stage were over 80 percent.
Instant Borate Crosslinked Fluid System:
Guar-based fluids provide a borate crosslinked gel fracturing fluid system that utilizes borate ions to crosslink the hydrated polymers and provide increased viscosity, delivering superior proppant transport while producing improved fracture conductivity with the system’s ability to break down and flow back effectively.
Crosslink systems provide options for a wide array of fluid and reservoir conditions producing a system with the ability to successfully stimulate reservoirs with high sand concentrations without sacrificing fluid rheology.
When compared to slickwater systems, crosslinked fluid presents far less fluid and pressure leak off into formation. By mitigating excessive fluid loss, fractures are able to accumulate sufficient fluid volumes to increase fracture propagation.
Delayed Borate Crosslink Fluid System:
Delayed borate crosslinked systems provide a gel fluid system that utilizes borate ions to crosslink the hydrated polymers after a predetermined delay to provide increased viscosity, delivering superior proppant transport while producing improved fracture conductivity with the system’s ability to break down and flow back effectively.
Delayed crosslink systems provide a fluid system with stable rheology at a range of conditions to suitably carry proppant into formation and develop large fracture networks down hole while being able to delay crosslink time to decrease friction pressure seen at surface.
CMHPG Crosslinked Fluid System:
Carboxymethyl Hydroxypropyl Guar (CMHPG) crosslinked fluid systems provide a zirconium crosslinked gel fracturing fluid system that utilizes zirconium ions to crosslink the hydrated polymers and provide increased viscosity, delivering superior proppant transport while producing improved fracture conductivity with the system’s ability to break down and flow back effectively.
CMHPG crosslink systems provide options for a wide array of fluid and reservoir conditions producing a system with the ability to successfully stimulate reservoirs with high sand concentrations without sacrificing fluid rheology.
