Assess Your Stress – Get Mohr From Your Microseismic

Presenter: Orlando Teran, PhD, Structural Geologist

Date: January 17, 2017


Summary: Focal mechanisms, when computed for an entire microseismic catalogue, permit a rapid assessment of the stress conditions throughout the entire stimulated reservoir. In this talk we will present a new geomechanical workflow using focal mechanisms to accurately and unambiguously estimate SHmax. We will demonstrate the importance of SHmax in achieving more precise frac design modeling results, as well as how the microseismic data permits us to evaluate the stratigraphic variations in SHmax. Additionally, by simply using the microseismic fracture orientations and this new workflow, we will show how we can identify fracture populations likely to control fluid flow, those that required different stimulation pressures in order to contribute to flow, and the mechanical conditions that favored out-of-zone growth and reactivation of geohazards. We will further show how by integrating stimulation data, such as net wellbore pressure measurements, and geophysical logs, can better constrain our geomechanical model as well as understand the adaptive controls affecting the overall stimulated rock volume.

Designing More Efficient and Effective Treatment Plans Using Full Moment Tensor Analysis of Microseismic Data

Presenter: Sudhendu Kashikar, VP Completions Evaluation

Date: September 20, 2016


Summary: Moment tensors are valuable tools for interpreting microseismic data from hydraulic fracturing as they describe the dynamic geomechanical response of the earth to the hydraulic treatment. The moment tensors and the focal mechanisms derived from them are becoming increasingly more sought after as a means to help integrate microseismic data with fracture modeling, reservoir engineering, and completions optimization.

Automatic calculation of moment tensors offers a distinct advantage in that it enables fast and efficient evaluation of numerous microseismic events and their possible source mechanisms with little need for analyst intervention. This facilitates a more detailed and accurate picture of stress and resultant fracture network both spatially and temporally. Such detailed moment tensor analysis makes it possible for the completion engineer to plug microseismic data into their fracture modeling in a more deterministic way so they can customize specific details of the treatment schedules and parameters. The most direct application of this type of analysis is identifying the net pressure required for activating various natural fractures and induced fractures in the rock. Being able to determine temporal changes in the stress fields offers a look into how the treatment is changing the stress field and provides a pathway to modify and alter the treatment to generate the desired near wellbore complexity and more effective fracturing.

Summary: MicroSeismic’s new AutoMTI tool calculates a discrete focal mechanism, the orientation of a fracture plane and the direction of movement, for every event, thus providing an adequate distribution of fracture plane orientations and slip vectors to perform statistically reliable stress field inversions. In this webcast, we will present our workflow on how we derive the fracture plane solutions, SHmax direction and magnitude, and how this can be used to understand the variations in the stress field throughout the reservoir during stimulation.

Rapid and Accurate Diagnosis of Well Performance Through Integrated Microseismic

Presenter: Sudhendu Kashikar, VP Completions Evaluation

Date: Feburary 8, 2016


Summary: In this webcast, we will look at several case studies that demonstrate how microseismic data offers the opportunity to make early, well specific, in situ observations of the permeability through stimulation. These observations can then be turned into a more timely and robust well appraisal, significantly reducing the need for 6 to 12 months of production data before appraising the well and diagnosing performance issues.

Seeking Real Value From Microseismic Monitoring | Early Appraisal of Unconventional Well Performance Using Microseismic Data

Presenter: Peter M. Duncan, Ph.D. – Founder & CoChairman, MicroSeismic, Inc.

Date: January 19, 2016


Summary: At every stage in the life of a well, estimates of what that well will recover and how much that might be worth are of primary importance. Before the well is drilled, the subsurface team uses the best G&G data available to forecast the value of the well and justify it being drilled. As the well is being drilled we anxiously watch the logs and cuttings to get hints on whether our predictions will bear out. After completion, we watch the IP as the well unloads hoping to see numbers that validate the prediction. In reality, all these are weak and highly uncertain indicators. We have to wait for 6 to 12 months of production history to really know how the well is going to perform over its life. In the meantime, we continue to drill more wells in an area that perhaps should be downgraded, we continue to complete wells with perhaps a less than optimal design and we continue to space wells based on a drainage model that may not be correct.

Microseismic data, that is the location of the microseismic events generated as the stimulation proceeds, have been used by the completion engineers to “watch” what is happening at the reservoir and confirm that the completion is going as planned. Various methods of mapping the extent of the microseismic cloud have been used to estimate the volume of stimulated rock (SRV) as a predictor of how the well will perform. Unfortunately SRV or the propped fraction of it alone are not reliable predictors of production since the amount of permeability enhancement within the SRV and its distribution are key to effective drainage of the hydrocarbons present.

Recent work has shown that microseismic data can also provide an insitu, real-time estimate of the permeability enhancement resulting from the treatment and its distribution over the SRV. This allows for an improved appraisal of the well within days of it being completed, without waiting months for production data. The workflow has been validated with long-term history matching to production.

The workflow and its output are the subject of this webcast.

Using Depletion-Zone Microseismicity to Understand Producing Volumes | Part 2

Presenter: Jon McKenna, Completions Evaluation Team Leader

Date: November 17, 2015


Summary: In Part 2, the methodology for separating microseismic events into different populations is further defined. This yields insight into an observed proppant distribution associated with offset producing wells, an observed fluid and proppant-laden gel distribution on stimulated wells, and depleted zones associated with offset producing wells.

In addition, the proppant-filled discrete fracture network model is validated by demonstrating that the modeled proppant distributions are very similar to the observed proppant-distributions on both the offset producing wells and the stimulated wells.

Using Depletion-Zone Microseismicity to Understand Producing Volumes | Part 1

Presenter: Jon McKenna, Completions Evaluation Team Leader

Date: October 20, 2015


Summary: Microseismicity is typically used to describe the region around the wellbore directly affected by the hydraulic stimulation. However, when wellbores are treated near offset producing wells, microseismicity can illuminate areas that have already been stimulated and can reveal important details about how the offset wells were treated, where production has occurred, and where hydrocarbons may have been left behind.

In this webcast, we will explain how to use microseismicity occurring on offset producing wells to understand and describe the region around the wellbore that was propped and where production has occurred. Using this information to test calibrated proppant filled fracture models, along with fracture velocities, helps evaluate the enhanced permeability around the wellbore from stimulation.

Geomechanics of Refracturing – Part 2: An Engineering Approach to Refracturing

Presenter: Alireza Agharazi, Petroleum Engineer

Date: August 18, 2015


Summary: As discussed in Part 1 of this webcast series, microseismic observations and geomechanical analysis of refracturing indicate that diverters are not effective in regulating the flow along lateral during the treatment.

Ineffective diverters and the pressure drop along the lateral, results in localized stimulation of reservoir at the heel area, leaving a major part of the well un-stimulated.

In part 2, we introduce an alternative method to address ineffective diverters and to improve the effectiveness of refracturing. This methodology is based on the stimulation of naturally fractured reservoirs by a pore pressure-driven mechanism. Proper handling of injection pressure and flow rates is a key factor in this methodology. Numerical simulations indicate the effectiveness of the method in creating a uniformly stimulated rock volume along the lateral.

Microseismic Correlation to Production

Presenter: Asal Zeynal, Petroleum Engineer & Mike Mueller, VP Development

Date: April 22, 2014 at 10AM CDT


Summary: The application of microseismic-based hydraulic fracture monitoring over the past decade of shale oil and gas development has reached the point where thousands of wells and tens of thousands of stages have been monitored. With this microseismic monitoring of a large number of wells, and sufficient time since initial production for many of the monitored wells, it is now possible to compare the microseismic results to multi-year production data across all of the active shale oil and gas trends. The correlations are based on using the stimulated rock volumes computed from microseismic pointsets and production data available from common reporting agencies. Overall these correlations are very promising with coefficients above 0.8 for all the prominent North American shale trends.

Productive-SRV: Proppant Placement and Production Estimation from Microseismic Data

Presenter: Carl Neuhaus, Petroleum Engineer at MicroSeismic, Inc..

Date: June 17, 2013 at 10AM CDT


This month’s webcast focuses on how using microseismic data allows users to build an event magnitude calibrated DFN, taking into account the seismic energy of the events, rock properties, and the pumped treatment. Evaluating proppant placement in the calibrated DFN allows you to discern between the part of the SRV that contributes to production in the long term, and the part of the reservoir that was affected by the treatment but may not be hydraulically connected over a longer period of time. Then obtaining reservoir characteristics from microseismic data gives you an idea of permeability that was created with the stimulation in order to evaluate drainage volume from where you are producing. From here you are able to estimate production, as well as refine field development in terms of wellbore spacing. Considering other treatment data, such as pressure and rate, we show how you can make additional recommendations on stage spacing and how to optimize your fluid system based on the signature of a proprietary treatment analysis plot.

Coupled Fluid Flow and Geomechanical Modeling of Unconventional Hydraulic Stimulation: Processing Affecting Recovery

Presenter: Mark McClure, Assistant Professor of Petroleum & Geosystems Engineering at University of Texas at Austin

Date: April 23, 2013 at 10:00 AM CST


During hydraulic stimulation in unconventional oil and gas, newly forming and preexisting fractures interact to generate complex fracture networks. We developed a computational model, CFRAC, that couples fluid flow and the stresses induced by fracture deformation in large, complex discrete fracture networks. Modeling these processes with discrete fracture networks is useful because the stresses induced by fracture propagation and deformation are specially heterogeneous and depend on the relative locations and orientations of neighboring fractures. The model also has the capability to describe friction evolution on fractures, allowing it to directly describe the processes giving rise to microseismicity. In this talk, applications to practical problems will be given. Different mechanisms that encourage or inhibit development of productive fracture networks will be summarized. The relationship between microseismicity and deformation will also be discussed.


Uncertainties in Surface and Downhole Microseismic

Presenter: Michael Thornton, CTO MicroSeismic, Inc.

Date: March 26, 2013 at 10AM CST CST


This month's webcast focuses on the presumption that the two competing microseismic imaging techniques in use today appear at first to be very dissimilar. Downhole microseismic locations are determined from P & S wave travel-time matching, much like traditional earthquake seismology, while surface microseismic imaging is more like pre-stack depth migration of reflection seismic. However, if one considers both techniques as maximum likelihood estimators (MLE), it is possible to show that the two are in fact quite similar. Moreover, the MLE framework provides a basis to compare the two methods in terms of the uncertainties in location estimates and sensitivity to velocity uncertainty.


Improving Event Location Accuracy with Anisotropic Velocity Models

Presenter: Carl Neuhaus, Petroleum Engineer, MicroSeismic, Inc.

Date: February 19, 2013 at 10:00AM CST


This month’s webcast focuses on the application of an anisotropic velocity model in determining microseismic event locations from surface-acquired passive seismic data. The Thomsen parameters ε and δ were determined to accurately locate calibration shots to their known location. Hydraulic fracture events where then imaged and compared to their locations derived from processing incorporating an isotropic velocity model. When compared directly to calibration shot locations derived with an isotropic velocity model, we will show that the absolute average error in calibration shot positioning in all directions was improved by almost 30% and hypocenter events from the hydraulic fracturing treatment depicted a more dense and confined zone of microseismic activity.


Microseismic Monitoring: Methods and Interpretation

Presenter: Mike Mueller, VP Technology Development, MicroSeismic, Inc.

Date: January 22, 2013 at 10 AM CST


The optimal horizontal wellbore orientation is generally orthogonal to the direction of hydraulic fracture propagation. There is a very little publically available data concerning the direction of maximum horizontal stress and natural fracture orientations in the Eagle Ford. In this webinar, the speaker will discuss how source mechanism analysis from surface-based microseismic results shows that the azimuth of hydraulic fractures in the Eagle Ford varies, depending on location. The optimal wellbore orientations varies as well. A range of wellbore orientation in the Eagle Ford Play is estimated using microseismic source mechanism analysis.

Integrated Microseismic Monitoring for Field Optimization in the Marcellus Shale

Presenter: Carl Neuhaus, Petroleum Engineer, MicroSeismic, Inc.

Date: October 23, 2012 at 10 AM CST


This webcast focuses on an integrative analysis of hydraulic fracture treatments conducted in the Marcellus Shale. The presentation determines how various factors related to the specific reservoir geology in the Marcellus and to what extent the variability of hydraulic fracture treatments impacted the microseismic results. It analyzes stress changes in the reservoir indicated by focal mechanisms to help explain the asymmetry of the microseismicity about the wellbore. Finally, the initial production results are compared to reservoir and engineering parameters to determine if the variability in the microseismic results is due to engineering differences or to spatially-varying reservoir properties.

Understanding Microseismic Positional Uncertainty

Presenter: Mike Mueller, VP Technology Development

Date: September 25, 2012 at 10AM CDT


Microseismic event location or position resolution and uncertainty remains one of the most critical aspects of passive seismic for the user community. Understanding the inherent capabilities, limitations and drivers for event locations from downhole, surface and near-surface microseismic acquisition geometries is required to have confidence with ‘beyond the dots’ microseismic applications such as hydrofracture length, height and stimulated rock volume calculations. In this webinar, these capabilities, limitations and drivers are reviewed for both the downhole and the surface acquisition methods.

Geological Interpretations of Microseismic Events to Better Constrain Fracture Models

In addition to locating microseismic events, MicroSeismic, Inc.’s surface and shallow buried array passive seismic technology is used to define the geometry and orientations of the fracture networks that are stimulated or induced by hydro-frac treatments. Additional rock mechanics parameters can be combined with additional information contained in the microseismic data to better understand in-situ subsurface stress and failure conditions.

In this webinar, the speaker will discuss focal mechanisms, stress inversion techniques, discrete fracture models constrained by microseismic events, and stimulated rock volume calculations. Additional analysis to be discussed include fractal geometries of event clusters, and event energy analyses can be used to optimize the stimulation treatment.
