Using Measured Solutions for Cost Savings — Lyoid Fussell
Using Measured Solutions For Cost Savings Presented By: Lyoid Fussell MEASURED SOLUTIONS Outline • What Are Measured Solutions? – – – – SpectraStim – Radioactive Tracer SpectraChem – Chemical Tracer SpectraScan – Radioactive Tracer Analysis Completion Profiler – Production Profiling • How Can Measured Solutions Cut Costs? – No Pay Left Behind – No Pay Compromised – Analyzing Techniques and Methods to Find What Works MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY SpectraStim • ZeroWash Tracer – Ir-192 • 74 Day Half Life – SC-46 • 83.8 Day Half Life – Sb-124 • 60.2 Day Half Life • Two Types – ZW – Crush Strength > 8,000 PSI – 40/70 Mesh • 2.65 Specific Gravity – ZWLD – Crush Strength 1,500 – 2,000 PSI – 40/70 Mesh • 1.3 – 1.48 Specific Gravity MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY SpectraChem • 14 Uniquely Identifiable Chemical Tracers – – – – – Can be injected individually in multiple stages. Can be injected in various segments of single stages. Flowback analysis quantifies load recovery and stages contributing to flowback. Analysis performed using gas chromatography and mass spectrometry. Also perform Ion analysis to quantify chlorides. MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY •Full Spectroscopy Memory Tool •Can be ran on SlickLine, Wireline, Coiled Tubing and Tractor •Records the Entire Energy Spectrum of Natural and Injected Gamma Emitting Isotopes. Did You Know? What Went Right? Pad DV Tool (4700' Uphole) Excessive Uncontained Frac Height Proppant Mechanical Failure Perforations Cement Channel Target Zone Stage Isolation Failure Frac Height Containment Stg 2 Squeeze Perforations Stg 1 Stage 2 Bridge Plug Intended Pay Stage 1 Perforated Out Of Zone Early Proppant Perforation Effectiveness Late Proppant Proppant Flowback Collar Locator Indicates Actual Perforations Downhole Video Revealed no Perforation Intended Perforations MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY Limited Entry Example – Does It Work? Ran Ir-192 Prior To Ball Drop Ran Sc-46 After Ball Drop Balls Created No Diversion We know what’s left behind, how do we get it? Next job pumped in two separate Stages. MR 1H – 7-Stg Cemented Horizontal 7 Stage Cemented Horizontal – Well A MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY MR 5H – 6-Stg Cemented Horizontal 6 Stage Cemented Horizontal – Well B MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY MR 1H 2 1000’ Parallel Offsets – Same Stage Volumes MR 5H MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY CONCLUSION • Using measured solutions you can ensure no pay is left behind, and your stimulation strategies are working. • Post job analysis takes on a new meaning allowing you to analyze what went right and clearly identify what went wrong. • You may be able to, use less expensive completion techniques, downsize job volumes, treat larger intervals, and isolate water and production issues. MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY CONTACT INFORMATION LYOID FUSSELL (918) 760-7775 Lyoid.Fussell@corelab.com http://www.corelab.com/pe/protechnics/ THANK YOU! MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY Frac Height Containment Did you know that fracture height growth was contained? Squeeze Perforations RESULT: Lost reserves due to unstimulated pay Intended Pay ACTION: Isolate lower perforations, perforate missed pay and re-frac BACK MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY Cement Channel Did you know that the cement job didn't isolate the formation? RESULT: Ineffective stimulation of target interval ACTION: Squeeze and restimulate BACK MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY Pad Did you know that there was extensive downward frac growth? Proppant Excessive Uncontained Frac Height RESULT: Ineffective stimulation with shorter than planned frac length Perforations ACTION: Use tracer data to recalibrate 3D frac model for the next well BACK MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY Mechanical Failure Did you know that the frac went through an uphole DV tool? DV Tool (4700' Uphole) RESULT: Ineffective stimulation of intended pay zone ACTION: Refrac the well down-tubing BACK Target Zone MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY Perforated Out of Zone Did you know the perforations were shot off depth? RESULT: The reservoir never had a chance to perform ACTION: Squeeze, re-perforte on depth and re-frac the target zone BACK Collar Locator Indicates Actual Perforations Intended Perforations MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY Perforation Effectiveness Did you know that the lower perforations did not treat due to ineffective perforating? RESULT: Bypassed reserves ACTION: Improve perforation QA/QC Downhole Video Revealed no Perforation BACK MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY RESULT: Damaged connection to the wellbore resulting in decreased production potential Early Proppant Did you know that the wellbore connection flowed back? Late Proppant Proppant Flowback ACTION: Refrac the well down-tubing BACK MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY Stage Isolation Failure Did you know that the stage isolation device failed during pumping of Stage 2? Stg 2 Stg 1 Stage 2 RESULT: Ineffective stimulation of Stage 2 and possible damage to Stage 1 fracture Bridge Plug Stage 1 ACTION: Re-frac Stage 2 BACK MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY BACK MEASURED SOLUTIONS THE COMPLETION DIAGNOSTICS COMPANY
