T2.3 Addressing Measurement Challenges in Today’s Shale Plays
As production continues to increase from unconventional shale plays in North America, factors such as live oil gathering systems, centralized processing facilities, volatile crude oils and higher BTU gases can present multiple challenges in measuring oil and gas from these plays. These challenges can have a severe impact on allocation, custody transfer and fiscal payments, and can cause system balances to exceed by up to 15 percent if not identified and addressed effectively. However, there are technologies and solutions that can adequately address these issues and provide valuable lessons to the rest of the world as their shale play developments progress.
The progression of hydraulic fracturing, horizontal drilling and the accessibility to hydrocarbons from shale formations has significantly changed the way unconventional oil and gas is produced, measured and transported. Environmental policies and landowner concerns are requiring operators to seek methods that mitigate the release of hydrocarbons to the atmosphere to preserve air quality and minimize the impact to the surrounding land. In addition, advances in production equipment are allowing operators to build more consolidated well sites with less equipment on location and less impact to the land. These policies and advances in technology have led to the development of multi-well pads, multi-phase gathering systems and centralized facilities used for the processing of the produced hydrocarbons. However, conventional measurement practices have not followed the same pace as the facility and gathering design changes, which is contributing to measurement error and system imbalances.
This presentation is intended to promote discussion of the challenges of accurately measuring wet gases and live oil, accounting for all produced fluids and applying value to shale hydrocarbons. It will also introduce and discuss solutions available in emerging technologies that improve metrology operations from an unconventional shale play.
This presentation will examine advanced measurement technologies and procedures that can help improve operational efficiency while lowering ongoing operational costs related to meter inspections, proving and sampling. Attendees will learn how to: identify the correct production profile; optimally size equipment used for fluid separation; use modeling data to predict hydrocarbon reaction to various temperatures and pressures; use a shrinkage factor to adjust measured volumes; and specify Coriolis and ultrasonic flow meters for advanced measurement calculations. The presentation will also help operators decide the value associated with each option and work with preferred vendors to make the appropriate measurement technology choices.
