Title: Fracture-Driven Interference and the Application of Machine Learning to Improve Operational Efficiency.

Speaker: Hayley Stephenson, Reservoir Analytics Engineer, Baker Hughes, a GE Company

Abstract:

There has been a significant amount of progress made applying data science techniques in the oil and gas industry over the last few years. These applications have occurred in all aspects of upstream, midstream and downstream sectors, but it is perhaps fair to say that direct application to reservoir centric challenges has not enjoyed as much success as when it has been applied to aspects of the value chain that experience direct observation and measurement by operators (e.g. optimization of facilities). Reservoirs, by their nature, introduce vast degrees of uncertainty due to their imperfect characterization and sporadic measurement and perturbation. Here we touch on several reservoir workflows incorporating data science and dive deep in to specific example involving frac hit mitigation.

 

Frac hits are a form of fracture-driven interference (FDI) that occur when newly drilled wells communicate with existing wells during completion, and which may negatively or positively affect production. An analytics and machine-learning approach is presented to characterize and aid understanding of the root causes of frac hits. The approach was applied to a field data set and indicated that frac hits can be quantitatively attributed to operational or subsurface parameters such as spacing or depletion. The novel approach analyzed a 10-well pad comprising two ‘parent’ producers and eight ‘child’ infills. The analysis included the following data types: microseismic, completion, surface and bottomhole pressure, tracers, production, and petrophysical logs. The method followed a three-step process: 1) use analytics to assess interference during the hydraulic fracturing and during production, 2) catalogue or extract feature engineering attributes for each stage (offset distance, petrophysics, completion, and depletion) and 3) apply machine-learning techniques to identify which attributes (operations or subsurface) are significant in the causation and/or enhancement of inter-well communication. Information fusion with multi-modal data was also used to determine the probability of well-to-well communication. The data fusion technique integrated multiple sensor data to obtain a lower detection error probability and a higher reliability by using data from multiple sources. The results showed that the infill wells completed in closest proximity to the depleted parents exhibit strong communication. The machine-learning classification creates rules that enable better understanding of control variables to improve operational efficiency. Furthermore, the methodology lends a framework that enables the development of visualization, continuous learning, and real-time application to mitigate communication during completions.

SPE YP | Lunch & Learn: Integrating Rock Properties and Fracture Treatment Data...

When: Wednesday, March 13, 2019 | 11:30 AM

Where: Liberty Oilfield Services | 950 17th Street #24, Denver, CO 80202


Title: Integrating Rock Properties and Fracture Treatment Data to Optimize Completions Design.

Speakers: Joel Mazza, Technical Solutions Manager & Carrie Glaser, Pethropysist, FractureID

Abstract

A horizontal well landed in a single formation rarely encounters homogeneous rock from the heel to the toe of the wellbore. When analyzing treatment responses that occur during hydraulic fracturing, a decreasing trend in surface treating pressure in sequential stages is typically attributed to reduced friction within the casing or frac string. However, there are several variances in treating pressure that are not readily explained by examining the surface pressures and pipe friction in isolation. These variances are also apparent when looking at bottom hole injectivity. Combining surface data and geomechanical data quickly reveals the degree of variability in rock properties along a lateral and the impact that variability can have on a completion, leading to a more optimal design. This paper demonstrates how engineers can take advantage of their most detailed completions and geomechanical data by looking for trends arising from past detailed treatment analyses and applying that gained knowledge to future completions.

This study relies on the analysis of proprietary high-resolution geomechanical data derived from the processing of accelerations measured at the drillbit and high-frequency fracture treatment data recorded at one-second intervals. The data were standardized to a common format, screened for quality control, normalized, and analyzed using a data management platform. The methodology combines critical mechanical rock properties such as Young's Modulus, and Poisson's ratio with high-frequency fracture treatment data, including treating pressures, rates, and fluid and proppant volumes. Further application of the geomechanical data to derive brittleness allows for construction of a more predictive petromechanical model to optimize completion approaches.

A brief analysis of past completions indicated virtually no correlation between gamma ray measurements along the stage and fracture treating conditions. However, when evaluating high-resolution mechanical rock properties along the lateral, a much more useful correlation exists between minimum horizontal stress variations (calculated from Poisson's Ratio) and eventual treating pressure and proppant placement difficulties. Calculated brittleness and bottomhole injectivity (which accounts for changes in slurry rate and pipe friction) also show a relationship, especially when cluster efficiency factors are included. This study of six Eagle Ford wells suggests that rock properties are the dominant variables affecting fracture treatment pressure and bottomhole injectivity. This method can be used to predict trouble stages, improve operational efficiencies, and optimize proppant placement.

This paper proposes a process to improve completion efficiency while demonstrating the value of information contained in high-resolution and high-frequency datasets. Historically underutilized, these datasets are playing an increasingly prevalent role in advanced analytics due to improved and novel technologies for data management and interpretation. This process is useful to ask better questions and to improve critical decision making with real data.

GENERAL MEETING | Developing the Next Generation of Completion Engineers

When: Wednesday, May 15, 2019 | 11:30 AM

Where: Denver Athletic Club | 1325 Glenarm Pl., Denver, CO


Speaker: Mark L. Van Domelen, Vice President of Technology for Downhole Chemical Solutions.

Abstract: 

As the development of oil and gas reservoirs continues around the world, the need for innovative solutions to economically produce these reservoirs remains as strong as ever. Building a talent base within an organization is paramount for this task. The successful exploitation of these often- challenging plays will require completion engineers who can implement new technologies and function within a multidisciplinary work environment. This presentation will describe technical training options and available resources for developing high performing completion engineers within an organization. A case study of an advanced engineering training program implemented within a major service company will be presented, along with recommendations for external training and development programs.

Our industry faces several challenges related to advanced engineering training and technology application including generation gaps brought about from industry downturns, global expansion of unconventional reservoir plays, cost constraints, and the complex nature of the reservoirs we work in today.   Companies that recognize this changing landscape and focus their efforts on engineering development will be rewarded with a more productive workforce, higher retention of their technical employees, and a more seamless transition through the years ahead.
