Presenting - "Demystifying Displacements- Taking a Black Art and Applying Engineering for Success"

 

There are many ways to displace a well and each client has their preferred methodology. The displacements for a cased-hole scenario in theory can be translated into open hole displacements up to a point.  By no means can they be handled in precisely the same manner.  Regulatory requirements also play a role in displacement design.  This presentation will take you through simple displacement concepts and how a displacement is thoughtfully engineered.

Presenting - "3D Displacement Dynamics and Real-Time Hydraulics: A Path to Instantaneous Validation of Annular Barriers."

 

The integration of 3D displacement dynamics and real-time hydraulic modeling plays a critical role in achieving instantaneous validation of annular barriers during cementing operations. By combining advanced computational fluid dynamics (CFD) with real-time data transmission, this approach significantly enhances the accuracy of fluid placement predictions and improves barrier integrity assessments in complex wellbore environments. Operators can now receive immediate feedback on cement placement and barrier effectiveness, reducing operational risks and improving decision-making during crucial stages of well construction. This innovation marks a significant advancement in optimizing cementing practices and maximizing long-term wellbore integrity.​​​​​​​

Presenting – “Impact of Fracturing Fluids on Hydraulic Fracture Modelling”

 

The impact of fracturing fluid selection on fracture modeling is critical to effective well completions, particularly in unconventional reservoirs where hydraulic fracturing is essential for economic production. Fracturing fluids, such as acids, slickwater, linear gels, and cross-linked gels, each influence fracture propagation, conductivity, and the induced stress distribution differently, impacting fracture geometry and connectivity within the reservoir. Acid-based fluids, which primarily react with carbonate formations, are often utilized to enhance formation etching and improve initial permeability, whereas slickwater is used to generate complex fracture networks in shale plays with minimal proppant transport capabilities. Linear gels provide moderate viscosity, enhancing proppant suspension without excessive friction, while cross-linked gels offer high viscosity for superior proppant transport in high-stress, tight formations. These fluids behave differently under various pumping rates; high rates can lead to extensive fracture networks with fluids like slickwater but may compromise control in stress-dominated environments requiring cross-linked gels.

 

Moreover, the design schedule of fracturing treatments—encompassing fluid type, pumping rates, and sequencing—often diverges from the actual treatment schedule due to on-site adjustments in response to real-time pressure and rate responses, leading to variances in fracture dimensions and conductivity. This discrepancy between design and execution can impact stress shadowing effects and fracture propagation, influencing long-term productivity and recovery. By examining the influence of fluid types at identical and variable pumping rates, a better understanding of fluid selection's role in fracture geometry and network complexity can be achieved, informing design adjustments for optimized reservoir stimulation.
