“…The wells might show an increase in water production and an increase or decrease in oil or gas production (Lawal et al 2013;Kurtoglu and Salman 2015). In addition, pressure testing on pad wells is often utilized to identify the well interference (Portis et al 2013;Sardinha et al 2014;Sani et al 2015;Scott et al 2015). Also, microseismic monitoring can be combined with the pressure test to improve understanding the well interference (Grossi et al 2015;Lehmann et al 2016).…”

“…Any well interference through the matrix in shale formations with ultralow permeability is more limited than that occurring through connecting fractures (Awada et al 2016). Although numerous pressure tests in the field have proven the existence of well interference (Portis et al 2013;Sardinha et al 2014;Sani et al 2015;Scott et al 2015), relatively few physical models exist to quantitatively simulate and explain the pressure response of shut-in wells. Marongiu-Porcu et al (2016) presented a state-of-the-art workflow by combining a complex fracture model, reservoir simulation, and geomechanics model to simulate complex fracture geometry, well performance, and stress properties to minimize undesired fracture hits.…”

“…This paper will build upon the well spacing toolkit described by Portis et al, (2013), including pressure monitoring during and after completions, as well as chemical and RA tracer data to constrain the extent of conductive fractures predicted by analysis of microseismic data and fracture modeling. Predictions of conductive fracture height growth will be confirmed by application of oil geochemical analysis.…”

Determination of proper well spacing is a key factor in successful resource play development. The objective is to optimize the spacing between wells that effectively stimulates the reservoir rock volume, increases overall recoveries and minimizes interference between wells. Recent work by Pioneer Natural Resources, Inc. (PXD) to optimize well spacing along the Eagle Ford Shale trend has resulted in reduced lateral spacing as well as vertical staggering of wells within the reservoir interval. Numerous tools are used to aid the determination of well spacing across the play, and it is critical to integrate data from all the tools available when establishing a spacing recommendation. The workflow presented is used to establish spacing recommendations through integration and analysis of multi-source data collected during the lifecycle of an unconventional resource play.The well spacing toolkit includes data collected from multiple disciplines in the asset. Microseismic data is integrated with 3D seismic data and fracture models to derive stimulated rock volumes. RA tracer and chemical fluid tracer data collected during well stimulation provide information on propped fracture length and height and inter-well communication, respectively. Pressure data recorded during well stimulation and interference tests performed after stimulation are used to help understand changes in well communication over time. Oil and gas geochemistry data from wells drilled in multiple stratigraphic intervals are used to provide insight on fracture height growth.The ability to integrate and analyze multi-source data is essential when establishing a recommendation on a complex problem such as proper well spacing; the workflow presented allows for the manipulation and visualization of these data in 4D that can be interpreted and edited by multiple users.

“…This interwell communication can be portrayed as "pressure sinks" that interfere with induced fracture effectiveness, and might affect unconventional EOR methods efficacy if they are overridden or not accounted for. For instance, numerous documented studies have demonstrated fracture interference occurrence and assessed this phenomenon in unconventional reservoirs (Ambrose et al, 2011;Manchanda et al, 2013;Portis et al, 2013;Sardinha et al, 2014;Sani et al, 2015;Awada et al, 2016;Morales et al, 2016;Klenner et al, 2018;Seth et al, 2018;Yu and Sepehrnoori, 2018). The current interest is focused on warding off negative impacts caused by fracture hits interwell propagation and affecting further productive wells.…”

First, I would like to express my profound gratitude to my academic supervisor Dr. Sepehrnoori for the continuous guidance and support during these two years of graduate school. I am truly grateful for his interest and willingness to guide me since the very first day of my graduate studies. I would also like to express sincere gratefulness to Dr. Wei Yu for his dedication, expertise advises, and insistent valuable guidance. I will always appreciate how he shared part of his extensive expertise in unconventional reservoirs, and reservoir modeling with me. Also, I would like to thank Erich Kerr and his company for supplying the field data that made this research possible. I gained great practice and understanding through their suggestions for my research work. Their invaluable support received weekly through my entire career will always be appreciated. There are not enough words to express how convinced I am that this would not have been possible without the support of my family. I thank my father Mario and my mother María for covering part of my tuition, and also my sister Carla Adriana for their continuous encouragement to pursue my dreams. I would like to thank Carolina for her caring love and support. I am indebted to my parents, my sister and my girlfriend who never stopped encouraging during both the good and the not so good times. I would also like to thank Reza, Sutthaporn, Fabio, Jorge, and Esmail for their collaboration and assertive comments for my work and my research. Finally, a very special acknowledgment is extended to the Fulbright Commission of Ecuador, the Department of State of the United States, and the Cockrell School of Engineering for being the sponsoring entities which provided me the scholarships to fund and make this accomplishment possible.
