Hydraulic fracturing has been used to stimulate hydrocarbon reservoirs for over 70 years, yet no single optimal methodology has emerged.

This talk will discuss a methodology that examines well heterogeneity, and designs the diversion strategy based on the rock properties within each fracturing stage. In addition to rock properties, the method proposed utilizes stress shadows, perforation design, and modified pump schedules to ensure equal cluster stimulation in diverter applications.

Horizontals, Multi-zone, Openhole Packers, Barefoot, ICDs, ICVs, Frac Valves, Plug and Perf, Unconventional – Why are there so many lower completion types? There is a better way – all lower completions could be redesigned as a two-trip and intervention capable system.

​Minifrac Tests are also known as: Fracture Diagnostic Tests (FDT), Fracture Calibration Tests (FCT), or Diagnostic Fracture Injection Tests (DFIT).

​For many years, the benchmark for indicating perforation performance in the well was a surface gun test into concrete. However, it became recognized that shooting an API concrete target at a surface could not be effectively correlated with actual downhole conditions of overburden, reservoir pressure and rock properties.

​As the industry moves to more complex multi-pad, multi-well completion designs, intelligent completion optimization will require more sophisticated algorithms to improve the decision-making process. This is where the use of analytics and AI can directly drive efficiencies to unlock the production potential of unconventional reservoirs specifically during hydraulic fracturing. The growing volume and availability of completion and production data creates a revolutionary situation where building reservoir potential maps, planning pads and optimizing completion designs begins to benefit from the use of AI methods.

The terms "Well Barrier" and "2 Independent Barriers" are used throughout well integrity management literature. However, there are misunderstandings as to what truly constitutes a Barrier and what are 2 Barriers, as opposed to 2 isolations or redundancy. Physical Barriers, their construction or installation and verification against performance criteria are the foundation of establishing and maintaining a well's integrity. Understanding how a system of components (barrier elements) is used to establish a barrier can become complex especially when there are multiple sources each requiring their own containment. This webinar will discuss and review fundamental concepts, to bring some clarity to these essential topics.

Over the last few years there have been several initiatives to instigate or update well integrity standards and practices around the globe. Two of these in particular will be discussed in this webinar. First, a summary of main highlights of the ISO Standard 16530-1 which was published in 2017 will be presented. Secondly will be some of the changes that have taken place in API RP 90, especially the newly issued first edition of API RP 90-2, published in 2016.

This lecture seeks to explain a systematic approach to characterize, constrain and validate such models through integration of prefrac diagnostic injections, core data, independently-determined fracture dimensions, and postfrac production data. The final objective is to build predictive models that can be used to improve completion strategies in this promising play.
