    DR. ANDREW CHEN has worked with Shell, BP, AJM Petroleum Consultants, Schlumberger and other companies, as a reservoir engineering professional/specialist, and has been responsible for operation reservoir engineering, oil and gas reserve evaluation and resource estimates, economical forecast, and North American unconventional plays, with more than 25 years of petroleum engineering and education experience. As an SME, he specializes in wireline formation test (WFT) design, data interpretation, operational practice, and technical training. During his tenure with Schlumberger Canada, he was responsible for providing a variety of engineering technical support, technical/data interpretation practice including training of operators and clients, troubleshooting tests in problematic reservoirs, and coordinating land and offshore projects for reservoir description and formation evaluation. Dr. Chen has provided consulting services in many Canadian and international companies in reservoir engineering, pressure transient analysis, and regional pressure data interpretation. He has been an instructor with OGCI/PetroSkills LLC for the course of "Wireline Formation Testing and Interpretation," and provides in-house practical WFT interpretation and technical workshops. He holds a PhD in fluid mechanics from the University of Manitoba, Winnipeg, Canada, and is a registered professional engineer of the Association of Professional Engineers and Geoscientists Alberta (APEGA). Before that, he held an academic teaching position for six years in reservoir engineering. Since 2011, Andy has worked extensively on various North American unconventional and semi-conventional plays, from early play evaluation, exploration drillings, production data analysis, early development planning, and portfolio risking and ranking assessment.

    DR. JOHN P. SPIVEY has over 20 years experience in the petroleum industry, with interests in pressure transient analysis, production data analysis, reservoir engineering, continuing education, and software development. From 1984 to 1990, he worked for SoftSearch, Inc. (later Dwights EnergyData) developing petroleum economics and engineering software. In 1990, he joined S.A. Holditch & Associates (SAH), which was purchased by Schlumberger (SLB) in 1997. While at SAH/SLB he conducted reservoir simulation, gas storage, and tight gas application studies and taught industry short courses in well testing and production data analysis. He actively participated in on-going development of SABRE, SAH numerical reservoir simulator, and in research in techniques for production data analysis for gas wells. He also designed and developed PROMAT, an analytical production data analysis and forecasting program, and WELLTEST, an interactive pressure transient test analysis program. In 2004, he started his own reservoir engineering consulting company, Phoenix Reservoir Engineering, and software development company, Phoenix Reservoir Software, LLC, which provides PMTx, a software package for analyzing production and production log data and forecasting future performance for multilayer low permeability reservoirs. Since 1992, he has served as Visiting Assistant Professor or Adjunct Assistant Professor at Texas A&M University, teaching undergraduate and graduate classes in gas reservoir engineering and pressure transient analysis, and serving on several graduate student committees. He is the editor of the SPE Reprint Series Vol. 52, Gas Reservoir Engineering, and Vol. 57, Pressure Transient Testing, and coauthor of SPE Textbook Series Vol. 9, Pressure Transient Testing and has published numerous papers and articles in industry journals and trade publications. He received a BS Physics from Abilene Christian University, a MS in Physics from the University of Washington, a PhD in Petroleum Engineering from Texas A&M University, and is a registered professional engineer in the state of Texas.

  • You will learn
  • Course Content
Formation testing and sampling tools (FTs) with wireline and while-drilling are widely used in exploration/appraisal and reservoir development projects. Over the past two decades, modern tools, such as MDT, RCI, RDT, and FRT, have emerged to become as one of the critical formation evaluation means in drilling projects with high cost/risk and high reward environments. In recent years, FT tools while-drilling provide alternatives of formation testing at earlier timing, flexible operational sequences in complicated wellbores access to reservoirs. FT pressure data and fluid samples are acquired for predicting hydrocarbon resource sizes and accessing key development uncertainties. This course is designed to satisfy the interdisciplinary needs of geoscientists, petrophysicists, and reservoir engineers with an increasing use of FT data. Practical and hands-on exercises are worked in the class. In the ends, the participants are expected to apply the learned skills in maximizing chances of acquiring quality data with improved formation evaluation outcome certainty.
Geoscientists, petrophysicists, wellsite supervisors, reservoir engineers, and geodata technologists of multidisciplinary formation evaluation and development teams engaging in explorations, appraisals, and field development activities.
How To:
  • Apply formation testing and sampling: technologies, applications, and limitations
  • Understand how FTs work; configure tool strings and design/ plan a test program
  • Perform QA/QC pressures and sampling data in real-time
  • Interpret pressure gradient data for fluid densities and contact levels
  • Understand reservoir connectivity/continuity and compartmentalization
  • Quantify uncertainties of data interpretation results
  • Interpret graphical techniques (scatterplot, excess pressures, normalization)
  • Design and interpret Mini-DST and VIT data
  • Why formation testing and sampling
  • How FT tools work; measurement principles; test types; drawdown mobility; data quality QA/QC
  • Pressure fluid gradient and contact level interpretation principles
  • Graphical pressure interpretation techniques: scatter-plot for gradient, FWL, and compositional gradient; excess pressure plot for compartmentalization; normalization plot for depleted reservoir
  • Multiple well pressure trends for reservoir compartmentalization, continuity, and extent
  • Qualification and quantification of interpretation uncertainties
  • Mud filtration phenomena dynamics; dynamic gradient; supercharging; wettability/capillary effects
  • Optical property measurement of reservoir fluids and contamination control; sampling principles and fluid sample QA/QC procedures; in-situ fluid PVT analysis
  • Permeability test; mini-DST and VIT; practical aspects of well productivity and deliverability potential estimates
