Halliburton’s FracFactory® service is a well stimulation service that can help accelerate an operators’ time-to-money, help improve operating efficiency for multi-well projects, reduce environmental impact, and reduce HSE exposure.
This manufacturing approach is a new concept for optimizing the efficiency of fracture stimulation operations in fields where well-spacing requirements and completion schedules involve large amounts of manpower, equipment and material.
FracFactory service is implemented from a base or central location to stimulate wells at distances ranging from several hundred to several thousand feet away. The remote wellsite is connected to the central location or pad by surface lines that typically consist of welded joints of tubing. The central location holds all the fracturing equipment. Frac crews work only from the central location, minimizing the need to move equipment, manpower and materials between jobs. The central pad is arranged to allow easy and efficient movement of equipment and fracing materials. Wireless technology relays pressure and density data from the wellsite to the TechCommand® center at the central location. Consolidating operations into a central, efficient location has proved to greatly increase the overall efficiency of fracturing operations.
Centralizing supplies, crew quarters, pumping and blending gear and water reclamation provides several benefits in addition to improved treatment efficiency such as aquifers and surface water are provided extra protection, the impact on local roads and wildlife is reduced, and remote locations can remain undisturbed.
The result? Reduced environmental disturbance, efficient energy use and simplified deployment logistics.
1--The operator of a tight-gas field in the Piceance Basin, Colorado, was under a financial time constraint and needed to stimulate 11 remote wells (63 frac jobs) located on a single pad, in 12 working days. A lack of available manpower prevented a 24-hr work schedule and required increasing the typical number of daily jobs from three or four per well to more than five. The operator chose FracFactory service to increase frac-job efficiency. All of the friction-reduced water fracs were completed with minimal problems and job efficiency was increased without sacrificing job quality.
The customer’s rate of return was improved by getting the wells on production sooner.
2--In another field, FracFactory service enabled six frac stages per well, with an average of one well completion per day. The number of wells per pad ranged from 4 to 21 and the remote frac pad was able to reach 5 to 10 well pads. The maximum length of the frac line was 13,200 ft and the maximum elevation change was 600 ft. Implementing the FracFactory service concept reduced NPT in this field by as much as 50%.
3--The FracFactory concept was used to frac wells in the Jonah field in the Green River Basin, Wyoming, where the well spacing is 10 acres. Two centrally located frac pads were used to perform 400 frac stages on 40 wells located on remote single- or multiwell pads; the maximum number of frac stages performed in any well was 12. The maximum length of the frac line was 6,800 ft.
