Spatial Analysis of Horizontal-Shale-Well Water Production in the Wattenberg Field
Reusing waste water from the oil field for hydraulic fracturing has become an important topic in the oil and gas industry, and it requires a thorough understanding of both the quality and quantity of the waste water. In this paper, water production from horizontal shale wells in five sections of the Wattenberg field in northeastern Colorado was analyzed. Models were developed for these wells for future water-production prediction. A spatial analysis was also conducted by comparing water production from each section with the gas/oil-ratio (GOR) value for each well. Results indicate that the GOR value of wells has a significant impact on water production in the first year of operation. Wells with low GOR value tend to have higher fracturing-flowback volume and, furthermore, water-recovery rate. Results from this study also provide valuable information for estimating water production from unconventional shale fields, which is critical for the design of wastewater collection and treatment facilities in the field.
How Water Management for Shale Oil and Gas is Evolving
An overview of some of the trends and issues related to water management for tight oil and gas are discussed, including environmental, sustainability, and legislative issues associated with water handling for hydraulic fracturing.
Incorporating Reuse: The Next Frontier for Produced Water Management
As producers and third-party vendors navigate the logistical challenges of water management, the push toward greater reuse of produced water has gained steam. How close is the industry to 100% reuse?
Are Your Produced Water Decisions Based on the Best Economics?
Recycling produced water may not be the soundest economic decision for operators of hydraulic fracturing projects. A water logistics expert examines the design considerations companies must account for with full-cycle water management systems.
