Mark A. Miller


Mark has nearly 38 years experience as a petroleum-engineering practitioner and educator, specializing in reservoir engineering, reservoir simulation, the reservoir engineering aspects of natural gas and naturally fractured reservoirs, thermal oil recovery, and petrophysics. After working for Getty Oil Company in a variety of petroleum engineering capacities, Dr. Miller earned a PhD in Petroleum Engineering from Stanford University. Dr. Miller subsequently served on the petroleum engineering faculty of the U. of Texas at Austin until establishing a consulting practice in 2001.


 



Narayan Nair


Narayan is a leader in Object Reservoir’s technology development and directly participates in the R&D for formulating practical and fast methods for analyzing well performance in Shale plays. In this capacity and his four years with Object Reservoir he has analyzed several hundred wells in the Haynesville, Woodford, Horn River, Montney and Marcellus Shale plays, focusing on improving capital and operational efficiency for shale well operators. Narayan Nair has an M.S.E and Ph.D. in Petroleum Engineering from the University of Texas at Austin.



Full Description
Shale resource plays often present formidable reservoir management challenges, particularly with regard to capital utilization and allocation. In spite of significant measurement and analysis, uncertainty typically remains in the physical characteristics of the stimulated reservoir volume (SRV) accessed by hydraulic fracturing, namely: shale permeability, fracture spacing, SRV spatial dimensions, and gas-in-place. In order to assess the viability and the impact of business and development decisions, a consistent workflow for analyzing well performance and predicting future performance is needed.
 
In this study, well performance histories of several hundred wells spanning the Haynesville, Woodford, Barnett, Horn River, Marcellus, Fayetteville and Montney shale plays were investigated with a common and consistent analytical framework that determined: a) a well productivity measure during transient linear flow, b) completion pressure losses (between sandface and bottomhole), and c) the onset of intra-fracture interference (internal SRV depletion). Parameters determined from the analyses are key indicators of the combined result of reservoir quality and hydraulic fracture performance. Results of this multi-well cross-play study provide information about both inter- and intra-play variability and commonality. 
 
In addition, the analytical methodologies used in this study provide a framework for diagnosing “problem well” performance issues. Several examples are presented, showing the likely effects of such things as poor fracture treatment results, frac hits from nearby wells and operational issues such as loss and gain of producing frac clusters.
 
The analytical approach utilized in this study can also be used to provide robust physics-based forecasts that directly recognize and incorporate interpretation non-uniqueness. Through a forecasting regimen that explicitly provides expected ranges of results, key field optimization decisions around well spacing and completion design can be made. Examples of this forecasting regimen demonstrate this capability.
