SPE Production Engineering Special Interest Group – Hydraulic Fracturing Technology Workshop

Event Description:

Join us for an insightful production engineering special interest group event on 20th Feb, 2023 at 7:30am at 31 Little Cribb St, Milton. The purpose of the event is to bring together technical professionals to discuss the latest developments in hydraulic fracturing. Three knowledgeable presenters will each share their expertise on various aspects of frac technology. After each 15-minute presentation, there will be a 10-minute question time to dive deeper into the topics. At the end of the presentations, a facilitated group discussion will be held, followed by networking opportunities. Ticket price is $10, which includes a food and drink voucher at the adjacent cafe. Don’t miss this opportunity to hear from industry experts and engage in meaningful discussions about hydraulic fracturing in the petroleum engineering domain.

Title:

Get more value and useful information from DFITs and how it impacts fracture treatments

Abstract:

Diagnostic fracture injection tests (DFITs) are commonplace, but how many DFITs are effective and properly planned to derive the desired information.  Many can be over large, perforated intervals or of such a volume such that specific stress information and clean diagnostic interpretations are not possible or filled with uncertainties.  This presentation will cover a strategy to gain more effective information from DFITs and the implications of the results for the more complex stress environments in Australia.

Title: 

The application of chemical tracers in multi-stage frac operations and completions

Abstract: 

Chemical tracers can be used for interventionless monitoring to evaluate fracture clean up, flow back efficiency and quantification. The basis of the technique utilises a family of unique, environmentally-friendly, fracturing fluid compatible chemical tracers to monitor each stage, immediately after fracturing treatments from multiple stages and their deterioration over time. The data is collected during clean up and steady state periods by collecting surface samples and analysed for their tracer concentrations over time. There are two different methods to deploy chemical tracers. The first method is pumping a known concentration into frac fluid stages as the frac fluid is pumped downhole. The use of the mass balance allows the flowback efficiency for each stage to be calculated. The second is to integrate chemical tracers into downhole completion equipment to provide the same as the first method but provide data over years, post frac. The latter allows multi-quantification results to assess the performance deterioration of each frac and identify the location of formation water breakthrough.

Title: 

How to do DFITs when the grass grows faster than pressure declines – application in unconventional formations

Abstract: 

Diagnostic Fracture Injection Test is a powerful method at a heart of microfracs, minifracs, extended leakoff tests. Unconventional shale and tight oil & gas formations are characterised by low permeability, and observing natural pressure decline to determine fracture closure is often not practical. Flowback at a constant rate was traditionally used by the industry. It requires specialized equipment and prone to human error that likely to create false signal. Constant choke flowback provides clean record devoid of interventions, can be executed using minimum equipment, but harder to interpret. This presentation covers application of Pump-in/Flow-back (PI-FB) in unconventional formations, pitfalls associated with near-wellbore stress concentrations and natural fractures.
