Constructing Typical Well Production Profiles

Workshop Leader: Dr John Lee, Professor of Petroleum Engineering, Texas A&M University Workshop Leader: Rod Sidle, Chair of the Reserve Definition Committee, Society of Petroleum Engineers (SPEE) Workshop Leader: Randy Freeborn, Chief Research Engineer, Energy Navigator Workshop Leader: Vitaliy Charkovskyy, Senior Petroleum Engineer, Ryder Scott


This workshop will focus on good practices for constructing “Typical Well Production Profiles” often called “Type Wells” or “Type Curves.”

These type wells are typically based on analysis of production information from an area of interest, often a portion of a shale or resource play, with the intent of predicting what the future rate profile will be for an existing well with limited production history, a new well that has not yet been drilled, or the outcome if a multi-well drilling program. These production profiles are important in property valuation, especially for financing, mergers, and acquisitions.

Recently published studies have identified practices that will enhance accuracy and other practices that are best avoided when constructing type wells. This information and more will be discussed in the workshop:


  • Identifying your objectives – Understanding your objectives to ensure work is consistent with these objectives
  • Selecting wells to be used in the construction of typical well profiles
  • Separating wells into the appropriate categories that recognize differences among wells
  • Determining the most likely, optimistic and conservative profiles for well subsets
  • Reviewing good practices to include and those to avoid
  • Methods of validating resulting typical well production profile to ensure it leads to accurate production forecasting

John Lee

John Lee is Professor of Petroleum Engineering at Texas A&M University. John holds BS, MS and PhD degrees in chemical engineering from the Georgia Institute of Technology. He worked for ExxonMobil early in his career and specialized in integrated reservoir studies. He later joined the Petroleum Engineering faculty at Texas A&M, and became Regents Professor of Petroleum Engineering. While at A&M, he also served as a consultant with S.A. Holditch & Associates, where he specialized in reservoir engineering aspects of unconventional gas resources. He joined the University of Houston faculty in September 2011 and held the Cullen Distinguished University Chair until September 2015. He served as an Academic Engineering Fellow with the U.S. Securities & Exchange Commission (SEC) in Washington during 2007-8, and was a principal architect of the modernized SEC rules for reporting oil and gas reserves. John is the author of four textbooks published by SPE and has received numerous awards from SPE, including the Lucas Medal, the DeGolyer Distinguished Service Medal and Honorary Membership. He is a member of the U.S. National Academy of Engineering and the Russian Academy of Natural Sciences.

Vitaliy Charkovskyy

Vitaliy Charkovskyy holds an MS degree in petroleum engineering from the University of Regina as well as MEng and BEng degrees in oil and gas recovery from Ivano-Frankivsk National Technical University of Oil and Gas in Ukraine. During his graduate studies at University of Regina, Vitaliy joined Energy Division of the Saskatchewan Research Council where he focused on reservoir simulation of various enhanced oil recovery schemes with an emphasis on application of the chemical and miscible floods to the Western Canadian Basin. Vitaliy joined Ryder Scott in 2012 and is currently a Senior Petroleum Engineer.  At Ryder Scott, Vitaliy performs reserves estimation and detailed technical studies utilization rate transient analysis and reservoir simulation. His areas of expertise also include evaluation of SAGD assets and technical studies focused on full field gas deliverability models.

Vitaliy is a Professional Engineer in Alberta and Saskatchewan and a member of the SPE.
