SPE Mid-Continent Luncheon Meeting — Tuesday, May 28, 2013

11:20 a.m.-1:00 p.m.

Tulsa Country Club

SpeakerStuart Cox, Marathon

Topic: "A Comprehensive Approach to Tight Oil Decline Curve Analysis"



Decline curve analysis in unconventional reservoirs is challenging due to extremely low reservoir flow capacity, completion techniques and production practices. The primary flow regimes for these wells include bilinear flow, transient linear flow, boundary influenced flow and long term linear flow. Classical decline curve techniques are applicable only during the boundary dominated flow period. Industry attempts to use decline curve analysis over the life of unconventional wells have been performed by imposing limits to the final decline in order to properly constrain estimates of future performance. Long term production performance data from most of these reservoirs is limited. One exception is the Bakken reservoir in North Dakota. Based on historical performance and conceptual studies, it is commonly believed that the dominate flow regime for unconventional developments will be long term linear flow. However, actual performance from recent Bakken and Eagle Ford completions do not always support this belief. Using historical Bakken and Eagle Ford production, this talk will challenge these concepts. Techniques to analyze performance using a flow regime based workflow to guide classic decline curve analysis will be presented. In addition to providing guidance for decline curve analysis, the proposed workflow can also be used to evaluate completion efficiency.

SPE Mid-Continent Section

The Mid-Continent Section of SPE was founded on December 28, 1917. It predated, by two years, the establishment of the American Petroleum Institute (API). Today, the Mid-Continent Section has over 700 members located in Tulsa, Oklahoma USA and surrounding area. Our diverse membership comes from a mix of medium and small businesses including major oil & gas companies, independent producers, drilling contractors, well services, equipment suppliers, gas transmission, universities, government agencies, and consultants.

The Mid-Continent Section maintains a tradition as one of the most active of more than 140 SPE sections in the world. One of its more unique activities is an annual series of 9 monthly luncheons with guest speakers, started in 1965, and continued through the present for over 40 years.
