Description

Activity in the Barnett shale of North Texas has continued to surge over the past several years, and with this surge in activity has come a steady evolution of completion techniques.  Most operators agree that the best Barnett shale wells are those that have the largest fracture network development.  One of the biggest challenges facing operators today is determining which completion techniques create the largest fracture network and the most effective diagnostic methods for evaluating these techniques in order to continue the optimization process. Numerous operators have used diagnostic techniques to optimize well placement and overall completion design. Approximately 20% of the Barnett shale completions have used radioactive tracers or chemical tracers to determine proppant placement, cement integrity, lateral cleanup, and offset well interference. 

Many operators are drilling parallel horizontals as close as 500’ apart. Simultaneous fracturing operations on these close offsets have also been used successfully in many areas. In general these techniques are being used to maximize fracture network development while possibly minimizing the number of surface locations. Additionally, with over 5000 available existing well-bores, re-fracture stimulations have become a significant piece in the evolution process.


This presentation will cover several Barnett Shale close offset and re-frac projects. The main discussion will deal with Spectral gamma ray logging results and chemical tracer results and how they were used to explain well performance anomalies. Additionally, we will utilize the sampling of chemical tracers to develop well-to-well interference profiles and help quantify communication between fracturing stages.

Dick Leonard is Dallas-Fort Worth Business Development Manager for ProTechnics, a division of Core Lab. Dick joined ProTechnics after working for 19 years with Union Pacific Resources in several engineering and supervisor positions. At UPR, the majority of his engineering experience dealt with the stimulation of tight sands in East and South Texas and horizontal development in North Louisiana. While he was engineering supervisor for East Texas, his group pioneered the water-frac technology that is currently being used in many tight sand and shale formations throughout the country. During the last 7 years, most of Dick’s focus has been on the diagnostic analysis of the Barnett Shale in North Texas. During his 29 years in the petroleum industry, Mr. Leonard has co-authored several SPE papers on hydraulic fracturing. Dick graduated from The University of Texas in 1979 with a BS degree in Petroleum Engineering. Mr. Leonard is a member of the SPE, API, AAPG, and AADE.
