GENERAL MEETING | Analytics, Physics, and the Truth

When: Wednesday, February 20, 2019 | 11:30 AM

Where: Denver Athletic Club | 1325 Glenarm Pl., Denver, CO

Speakers: Donny Keighley and Kerstan Wallace, Encana

As engineers and geoscientists, a big part of our job is creating models to explain and predict well performance.  We have no problem running physics based simulators, feeding machine learning algorithms, and creating mental models.  Unfortunately, we also have no problem believing our models without bothering to check if they’re any good.  While there is no perfect way to predict reservoir behavior given time, budgetary, and physical constraints, we think that reservoir management can be improved by questioning personal biases, making/checking rigorous predictions, and simply being honest about what we do and don’t know.

Speakers Bio:

Donny Keighley graduated from the Colorado School of Mines in 2004 with a BS in Geophysical Engineering and again in 2006 with an MS in Geophysics.  Since then, he has worked at Encana in Denver on various teams including Jonah, New Ventures, Permian, and Business Development.  Like many geophysicists, Keighley slowly morphed into a different role -- in his case, a data analyst.  Currently, he works on the Business Development team analyzing all types of data, making and using predictive models, and streamlining processes using R programming.




Kerstan Wallace received his B.S. and M.S in geology from the University of Texas at Austin. After graduating in 2013, Wallace joined Encana and has been working with the company for 5+ years. During that time he has held various roles in operations and reservoir characterization. Wallace's primary areas of focus is in subsurface data analysis, geomechanical modeling, and, most recently, well performance data analytics. Over the last few years, Wallace has been responsible for developing a predictive well performance model in the Permian Basin used to help guide program development decisions.

CONTINUING EDUCATION | Artificial Lift and Production Optimization Solutions

When: Tuesday, February 26th and Wednesday, February 27th, 2019 | 8:00 AM - 5:00 PM

Location: Liberty Oilfield Training Room, 950 17th Street, Floor 24 Denver, Colorado 80202


Members: $1400

Non-Members: $1800

Registration Cutoff: Friday, February 22nd, 2019


This course is designed to give trainees an overview of various artificial lift solutions and related production optimization concepts. After introducing participants to the need for an artificial lift system, training will focus on each of the following lift methods: Gas lift, Reciprocating Rod Lift, Progressing Cavity Pumping, Hydraulic Pumping, Electrical Submersible Pumping, Plunger and Capillary System. For each lift type, the course covers main components, application envelope, relative strengths and weaknesses. Animations, field cases, and example-calculations are used to reinforce concepts. A unique feature of this course is discussion on digital oil field as applicable to lift optimization. The course will close with a discussion session wherein trainees would discuss their challenges and plans for lift systems with a view to understand applicability of the concepts learned during the training.

Learning Level

Intermediate to Advanced, depending on course length selected.

Course Length

2-5 Days (The course length may be adjusted to meet the learning level of the target audience.)

Why You Should Attend 

Every oil and gas well requires a lift mechanism at some time-point. Often times during a well’s life cycle, changing conditions, necessitate switching from one to another lift method. Each lift system’s applicability often overlaps with other lift systems and it is important to understand when to use one and why not to use another. This course while providing instructions at awareness level will arm attendees with sufficient details to participate in informative decision making process.

Who Should Attend

Anyone interested in learning about lift systems application. Production and field operations engineers, operators, geoscientists, and reservoir engineers who wish to understand the implications of lift systems on their field/reservoirs.

Special Requirements

COMPLETIONS & PROD STUDY GROUP | Addressing Well Interaction with the Help of Microseismic...

When: Thursday February 28, 2019 | 11:30 a.m to 1:00 p.m.

Where: Halliburton | 1125 17th Street, Suite 1900 Denver, CO

Title: Adressing Well Interaction with the Help of Microseismic: Enhancing Integrated Diagnostic Data Streams with Heatmaps.

Speaker: Hannah Chittenden, Geophysical Analyst and Project Coordinator, ESG Global Energy


It is well understood that in today’s field development, well communication and interaction is a problem influencing production in both parent and child wells. While frac-hits are not a new phenomenon, infill drilling and tighter well spacing of horizontal pads in areas like the Permian and Eagle Ford have intensified the issue, leading to appreciable production losses or diminished producing capacity in many wells. 1 Some operators have taken a broader field wide approach to mitigate production loss, using techniques such as simultaneous operations or tank development2 while others propose pre-loading parent wells3 or customized well sequencing4 , all in efforts to generate protective pressure barriers between wells. However, with the added complexity of subsurface heterogeneity, operators need to consider a custom approach to developing their own mitigation solutions. Microseismic analysis, in conjunction with other diagnostic data streams such as tracers, fiber, geomechanical modeling and pressure data, can provide key feedback on the nature of well interaction. While assessment of microseismic event clouds can provide evidence of interaction, it lacks the resolution required to fully assess the mechanisms driving this interaction. Building on a new approach to interpreting microseismic data that emphasizes spatial and temporal trends in seismicity over discrete event locations, zones of “wet” and “dry” seismicity are visualized in heatmaps as a function of reservoir stress conditions, providing operators with a visual tool to evaluate the degree of interaction between wells. Looking at trends in seismicity at the stage-level and across a pad in conjunction with additional diagnostic data streams provides greater clarity on zones of communication or interaction between wells. With a better understanding of the nature of this well interaction, operators can make important decisions around well spacing, frac sequencing and completions design to optimally stimulate a reservoir while minimizing production losses associated with unintended interaction. Here we present a case study from the Permian basin to demonstrate how integrated data streams can be enhanced with microseismic data to provide additional knowledge of the mechanisms driving well interaction, and offer insights to operators to help mitigate the risk of frac-hits.

Title: Integrating Rock Properties and Fracture Treatment Data to Optimize Completions Design.

Speakers: Joel Mazza, Technical Solutions Manager & Carrie Glaser, Pethropysist, FractureID


A horizontal well landed in a single formation rarely encounters homogeneous rock from the heel to the toe of the wellbore. When analyzing treatment responses that occur during hydraulic fracturing, a decreasing trend in surface treating pressure in sequential stages is typically attributed to reduced friction within the casing or frac string. However, there are several variances in treating pressure that are not readily explained by examining the surface pressures and pipe friction in isolation. These variances are also apparent when looking at bottom hole injectivity. Combining surface data and geomechanical data quickly reveals the degree of variability in rock properties along a lateral and the impact that variability can have on a completion, leading to a more optimal design. This paper demonstrates how engineers can take advantage of their most detailed completions and geomechanical data by looking for trends arising from past detailed treatment analyses and applying that gained knowledge to future completions.

This study relies on the analysis of proprietary high-resolution geomechanical data derived from the processing of accelerations measured at the drillbit and high-frequency fracture treatment data recorded at one-second intervals. The data were standardized to a common format, screened for quality control, normalized, and analyzed using a data management platform. The methodology combines critical mechanical rock properties such as Young's Modulus, and Poisson's ratio with high-frequency fracture treatment data, including treating pressures, rates, and fluid and proppant volumes. Further application of the geomechanical data to derive brittleness allows for construction of a more predictive petromechanical model to optimize completion approaches.

A brief analysis of past completions indicated virtually no correlation between gamma ray measurements along the stage and fracture treating conditions. However, when evaluating high-resolution mechanical rock properties along the lateral, a much more useful correlation exists between minimum horizontal stress variations (calculated from Poisson's Ratio) and eventual treating pressure and proppant placement difficulties. Calculated brittleness and bottomhole injectivity (which accounts for changes in slurry rate and pipe friction) also show a relationship, especially when cluster efficiency factors are included. This study of six Eagle Ford wells suggests that rock properties are the dominant variables affecting fracture treatment pressure and bottomhole injectivity. This method can be used to predict trouble stages, improve operational efficiencies, and optimize proppant placement.

This paper proposes a process to improve completion efficiency while demonstrating the value of information contained in high-resolution and high-frequency datasets. Historically underutilized, these datasets are playing an increasingly prevalent role in advanced analytics due to improved and novel technologies for data management and interpretation. This process is useful to ask better questions and to improve critical decision making with real data.
