Dissolva-Perf
Overview
•Provides full wellbore integrity until a pre-determined time.
•Ports dissolve to allow communication to the formation.
•Variable dissolve rates can be achieved by changing material compositions or wellbore fluids.
•Provides a low-cost alternative to perforating and mechanical sleeves.
•Simulate any SPM / Phasing / Shot Density
•100% successful initiations


Applications
•Multi-stage frac operations using coiled tubing w/ isolation tool
•Full-wellbore stimulations
•Single or Multi-stage toe initiation
Deployment Methods
- Setup to dissolve in days to weeks
- Dissolve one or more subs at the same time
- Simulate first stage cluster
- Pressure test to MACP during well integrity period
- Begin fracturing operations

- Setup to dissolve in days or weeks
- Pressure test to MACP during well integrity period
- RIG w/ Cup-Cup tools for single point stimulation

- Setup to dissolve in days to weeks
- Pressure test to MACP during well integrity period
- Continuous frac ops
- Drop pods to isolate treated intervals and divert proppants to new clusters
- Ideal for longer laterals where coil and wireline cannot reach

Benefits

Dissolva-Perf – Case Study #1
5-Stage Toe Cluster Deployment – Duvernay
Test Plan
- 6 well completion program
- 5 wells utilized conventional PnP methodology for first stage completion
- 1 well, 5 stage cluster of Disolva-perf subs installed

Highlights
- 100% isolation during installation and cementing
- Achieved required hold and dissolve time
- Full open access of all ports to formation
- no restrictions in flow area
- Higher than average treating rate
- Outperformed the perforating stages

- Early time pressure reduction, potentially perforation/cement erosion and critical frac path being established
- Higher treating rates could be due to no stress cage effects created during ballistic perforating events
- Results indicate stage 1 behaved in similar fashion to standard design

Interval #2-5 frac charts

Dissolva-Perf – Case Study #2
18-stage, Coiled Tubing Cup Frac Operation
- 100% success
- One screen out mid-stage. Correlated to lover quality reservoir
- Average treating rate and pressure same as conventional methods (perforating, burst ports)
Time Savings: 1.2 Days
Cost Savings: 50%/stage
