Lunch & Learn—Announcement of FracRx—Just What the Dr. Ordered
MicroSeismic has an announcement of seismic proportions! Hint…it’s not another new product announcement, and it may just “rock” your world! Join us for a Lunch & Learn where Peter Duncan, MicroSeismic CEO will share some groundbreaking news!

Completion and Wellbore Geomechanics in High Stress Settings—A Case Study from the Vaca Muerta Formation
We will present observations from the hydraulic fracturing of two horizontal wells in the Vaca Muerta. We show that initial estimates of SHmax from sonic logs were not nearly as large as that required to explain the reactivation of shallow-dipping thrust faults and wellbore stability issues. Real-time moment tensor inversion and geomechanics provide the detectability and mitigative solutions that can reduce negative economic impacts for better field development.

Driving ROI in Unconventionals
Verisei’s Active Decision Model (ADM) links a company’s financial value to the specific actions that drive it. Using transparent logic and a simple interface, it enables teams to quickly evaluate the financial impact of alternatives and make better decisions. We will demonstrate how the model can be integrated with
FracRx monitoring technology to make real-time stimulation treatment decisions based on optimal financial impact.

Determining Optimal Completion Design Using a Multi-Well Downhole Array
A well-designed array is used to monitor single-stage hydraulic treatments in the Canyon Creek Formation. Completions evaluation of the result leads to several recommendations including appropriate job size, completions order and perforation suggestions.

Frac Hits: Parent Child Well Interaction
Infill drilling and hydraulic fracturing of new wells are placing wells at risk of suffering premature production declines. In some areas of the Permian, frac hits have caused child wells to deliver a 30% lower recovery rate than their parents. Some parent wells impacted by frac hits never fully recover and, in the worst cases, permanently stop producing. We will discuss the known causes of this issue as well as the tools and analysis that are currently available to help you detect and mitigate frac hits.

Impact of Frac Hits on Production Performance
Analysis results from a wide range of data sets, from microseismic monitoring to production data provide a new insight into how the initial well communication
during stimulation impacts the well interference during production.

Microseismic Bedding-plane Slip Theory – Requires a Very Slippery Slope or a Very Large SHmax
There is much discussion on associating microseismic activity with the reactivation of bedding planes near the hydraulic fracture tip. Yet evidence for bedding-plane slip has not been observed in cores of stimulated rock volumes, and a consensus on how to integrate bedding plane slip in fracture and reservoir models has not been established. We will demonstrate geomechanical criteria for when and where to interpret microseismic data as bedding-plane slips and the importance of using microseismic data to simulate and forecast reservoir performance.

Sensitivity of Well Performance to Well Spacing and Configuration
To better understand well communication, we applied an integrated workflow to quantify the effect of various well and completion designs on the well performance of unconventional shale reservoirs. The applied workflow offers a new systematic approach of field development for E&P companies aiming to understand optimal well spacing and location for new pads for improved economics of the field.

Tank Development and Estimating Drainage Volume
Full-field development with high wellbore density in multiple target zones poses challenges regarding interaction between wellbores and decrease in recovery per section. Microseismic-based reservoir simulation is used to understand the draining volume and identify optimum wellbore spacing.

Improved Understanding of Multi-well Completion Programs: A Case for Multifaceted Data Visualization
Analysis of microseismic data yields a wealth of high-dimensional information that can be leveraged to better understand complex multi-well completions. Too
often our understanding is limited by the constraints of data visualization; we will present a series of novel data visualization approaches aimed at illuminating pathways for improved treatment efficiency.

Understanding Induced Seismicity in the Montney using Lab, Production and Theoretical Data
Understanding fracture mechanics of Montney shale during completion operations is fundamental in assessing their effectiveness, forecasting associated production, and its induced seismic signature. Combining observations from hydraulic fracturing experiments in the lab and production data (ISIP and DFIT) provides us with insights suggesting that the complexity of the fracture network during frac’ing operations is fully dominated by the failure or reactivation of the pre-existing flaws (bedding planes, faults, etc.).

Understanding the Vaca Muerta Formation
Results from four wells in the Vaca Muerta provide insight on preferred horizontal well orientation, spacing, and landing zone and also helped establish the feasibility of a permanent, life-of-field array that was installed during the pilot phase of field development.
