Halliburton has announced the release of the CYPHER聽2.0 Seismic-to-Stimulation Service, a proprietary and collaborative workflow that links geoscience and reservoir, drilling, and completion engineering to allow operators to better predict and produce unconventional reserves. The CYPHER 2.0 service builds on the complete full-field solution and provides enhanced capabilities through innovative software applications allowing operators to optimise the development of their unconventional reservoirs and reduce their cost per barrels of oil equivalent.

Powered by Landmark鈥檚 DecisionSpace^庐 next-generation earth modelling solution, the workflow is unique to the industry in that it is capable of updating dynamically and iteratively with the seismic and well data required to model the structure, rock and fluid properties. Halliburton鈥檚 petroleum systems modelling technology defines the distribution of hydrocarbons in the unconventional reservoir to aid well placement, while the company鈥檚 integrated formation evaluation module identifies the sweet spots for optimising the spacing of perforation clusters.聽

Modelling the reservoir鈥檚 natural fracture networks

Key scientific and technological advances in the CYPHER 2.0 service include modelling the interaction of the reservoir鈥檚 natural fracture networks with the fractures induced by the hydraulic fracturing process. This results in a more accurate fracture network model with which to simulate the production performance of the completion design. Critical operational factors can then be adjusted in real time between stages during the fracture treatment to further optimise well performance. Another advancement is the ability to evaluate, predict and alter perforation cluster efficiency.聽Leveraging these models to rapidly evaluate the production performance of different well placement and completion design options, Halliburton is able to聽quickly and iteratively optimise the development plans for operators鈥� shale assets.

鈥淪ince we released the CYPHER service聽in September 2013, we have seen tremendous customer interest and uptake,鈥� said Jim Brown, Halliburton鈥檚 President of the Western Hemisphere. 鈥淧rojects on shale assets in several North American basins have delivered a 35% production increase on average. The CYPHER 2.0 service is a step-change improvement in our ability to deliver better wells for our customers at a lower cost per boe.鈥�

Customer reactions

Devon Energy first applied the CYPHER service in the Grasslands Area of the Northern Barnett Shale. After seeing improved production results and EURs with far less production variations between wells, Devon has chosen to incorporate the CYPHER service in the Eagle Ford Shale as part of their technology efforts to help them better understand the reservoir and also aid in the stimulation design to help improve their fracture efficiency and effectiveness.聽

Synergy Resources Corporation鈥檚 Chief Operating Officer Craig Rasmuson had this to say after using the CYPHER service: 鈥淗alliburton increased the 30 to 90-day production rates with its CYPHER service through prior planning and diligent management of the drilling processes, ultimately increasing the EURs and reserves for Synergy which is why we wholeheartedly endorse the CYPHER service.鈥�

The CYPHER service is deployed to all major shale developments in North America and many key international markets through multi-disciplined technical teams, with more than 300 technical professionals trained on major elements of the workflow.
