Title: "Integrating Multiple Diagnostic Methods to Determine Limited Entry Treatment Effectiveness"

Speaker:  Dave Cramer, 2021/2022 SPE Distinguished Lecturer and Senior Engineering Fellow for Conoco Philips Global Completions.

Abstract:

This presentation covers the essential elements of limited entry treatment design and reviews a case study of plug-and-perf horizontal well treatments in an unconventional shale play. In the case study, various diagnostic methods were used to better understand and quantify the factors determining limited entry effectiveness. Three diagnostic methods were implemented: 1.) injection step-down tests and pressure analysis of the fracturing treatments, 2.) video-based perforation imaging and 3.) distributed acoustic sensing (DAS).

In-situ stress variation and perforation erosion were determined to have significant impacts on treatment allocation among perforation clusters. Other undesirable effects such as heel-side flow preference were also observed. Camera images confirmed proppant-induced erosion at the scale of individual perforations. Measurements from the digital images provided comparison points for predictive software using surface pressure measurements. DAS results provided cluster level proppant distribution values. Correlations were also observed between treatment allocation values from DAS data and values derived from perforation friction calculated from Bernoulli’s equation using the image-based entry hole diameter data.

The results of the case study indicated that a staggered perforation design using more gradual changes among clusters would lead to a more balanced treatment. This scenario was evaluated along with a job design featuring high excess perforation friction and an equal number of perforations in each cluster. Fracture-simulation runs indicated that both tactics are likely to improve slurry allocation.

The key take-away from this lecture is that limited entry treatments can result in effective stimulation along the entire wellbore when the best practices disclosed in the presentation are followed.

SPE General Meeting | Unified Well Spacing and Completion Design for Unconventional...

When: Wednesday, November 17, 2021 | 11:30 am to 1:00 pm

Where: Denver Athletic Club | 1325 Glenarm Pl, Denver, CO 80204


Title:  "Unified Well Spacing and Completion Design for Unconventionals – A Physics and Data-Driven Approach"

Speaker: Walter C. Dobbs, International Reservoir Technologies, Inc. 

Abstract:

Development of unconventional plays requires an early election of horizontal well targeting and spacing.  As operators fine-tune development plans, changes to that initial framework can take years to implement due to long lead times for land, permitting, and planning.  However, hydraulic fracturing design remains a more flexible design element, representing a powerful force for optimization.

With a combination of accessible physics-based modeling and data analysis, engineers can see through the noise of multi-variate systems to create high-confidence integrated well spacing and completion designs for frontier and mature field development and for campaigns that have been drilled but not yet stimulated.  This approach mixes long-standing reservoir engineering practices with developing ideas about how to represent the hydraulic fracturing process and response.

A Dynamic Stimulated Reservoir Volume modeling workflow constrained against treatment, flowback, and production data enables engineers to interpret the most efficient stimulation fluid volume and forecast performance for any system.  Model predictions and field data are unified in an elegant visualization that illuminates a complex multi-well design space.  Insights about the impacts of geology and reservoir conditions highlight the potential for design customization across the play.

In stacked plays, the application of these techniques becomes even more important.  This workflow was developed and applied extensively in the Denver-Julesburg Basin Niobrara play.  The asset team validated the approach against a 70-well field trial then used it to decipher regional performance and ultimately to post-appraise and design drilling and completion campaigns for the most efficient use of capital.

SPE General Meeting | Solving Gas Interference Issues with Sucker Rod Pumps

When: Wednesday September 15, 2021 | 11:30 am to 1:00 pm

Where: Denver Athletic Club | 1325 Glenarm Pl, Denver, CO 80204


2020/2021 SPE Distinguished Leturer

Speaker: Anthony Allison, Senior Artificial Lift Advisor at Occidental Oil & Gas

Abstract:

Gas/liquid ratios (GLRs) typically increase later in the life of a sucker rod-pumped well, and unconventional reservoirs may have high GLRs from the beginning of production.  How to handle that gas production is important for sucker rod pumps, as the efficiency is reduced when gas enters the pump.  A project was undertaken to quantify several methods used to handle gas production with sucker rod pumps and the effectiveness of each.

This project focused on three areas of design or operation intended to improve gas handling:

·       Gas separator design:  The sizing of downhole gas separators was reviewed, and steps were taken to match the pumping system with the proper separator.  In cases where the separator was not pulled, the pump displacement was adjusted to ensure it was within the capacity of the existing separator.  Where there was an opportunity to replace the separator, the design was modified to ensure the separator capacity matched the expected well production.

·       Variable speed drives:  Horizontal wells do not provide consistent inflow, but rather exhibit slugging behavior as portions of the lateral load up with liquid or gas.  This makes pump-off control difficult with conventional rod pump controllers, which stop the pump completely when there is a lack of fluid at the pump.  The performance of variable speed drives was studied to determine if continuous operation while adjusting the speed to accommodate slugging would improve production.

·       Backpressure valves:  Backpressure has been used as a method to improve the performance of wells with gas interference, but the benefits have been questionable compared to the negative impacts on equipment loading.  Wells with elevated tubing backpressure were identified, the backpressure was reduced to line pressure, and the impact on performance was monitored.

COMPLETIONS STUDY GROUP| A New Approach to Sealing Unwanted Casing/Liner Perfs, Breaches and Leaks

When: Tuesday May 25, 2021 | 11:50 a.m. to 1:00 p.m.

Where: Zoom


Presenter/Author: Dale Larsen, Business Development Manager, New Well Tech, LLC

Abstract:

A Sealant Material to Fix Wellbore Leaks, Breaches, Unwanted Perforations and Water Flows

Objectives/Scope: Shale wells often drop to sub-economic levels in a relatively short period of time due to rapid production decline, water production, or wellbore interference issues. To salvage these wellbores, it requires a reliable method to fix their leaks and breaches or to block the unwanted fractures and perforations that already exist from the original completion.

A sealant material has been developed which is liquid on surface, then cures to form a pliable solid that can seal unwanted perforations or fracture openings.

Field tests were performed on a vertical well that had been fractured in two stages. The sealant material was bullheaded into both perf clusters simultaneously. It was then squeezed into the formation while slightly under displacing. After the material cured to a solid, the excess remaining in the wellbore was drilled out. Pressure tests were done on both intervals to see how much differential pressure the sealant could hold.

Results/Conclusions: After cleaning out past the top perforation cluster, the zone was pressure-tested up to the maximum allowable wellhead pressure. After holding for 25 minutes, the pressure was released and drilling was resumed on the sealing material that covered the lower interval.

Applications/Significance: This sealant material gives a cost effective and relatively low risk alternative to repair the well. The sealant material requires relatively small volumes and hence is cost effective. Lab and field test showed that the reaction can be controlled, which minimizes the risk that this sealant may set up too early or too late. Field tests also showed that it was easy to drill out the residue left in wellbore. It leaves original wellbore ID intact and it seals off not only the wellbore opening, but also near wellbore pathways, such as multiple fractures, cement channeling, and the open hole annulus of a sliding sleeve completion. With this material as a tool to increase the production of declining shale wells, the need for new replacement drilling may be averted saving money to the operator and decreasing the environmental impact.
