GAZ & MASLO: autoRTA, Diagnostics, and Forecasting

Introduction

The AFA™ GAZ and MALSO modules have a variety of automated solutions for highly complex engineering workflows. This is includes the introduction of the automation transient methods and related workflows - also great tools for reservoir performance analysis and production forecasting.

Automated Type Curve Analysis

Using advanced data science and/or machine learning, the traditional method of manually performing RTA type curve matches, following by forecasting can be automated by the AFA™ platform.

MultiFractured Horizontal Well (MFHW) Capability

AFA^TM has MFHW capability that allows for custom number for fractures and frac lengths along the well. The model will handle all flow regimes, pre and post inter-fracture interference.

Automated History Matching & Forecasting

Both automated analysis, history matching, and forecasting represents a substantial improvement workflows, compared to traditional methods. After easily performing an automated type curve for the transient and PSS parameters, the forecast is can be automatically generated. Anchor to pressure or rate constraints.

Types of Models

Currently, the following features/models are enabled in AFA™ autoRTA for both oil and gas. These models have applications for both conventional and unconventional systems.

Model	Dual Porosity	Boundary Condition
Vertical Well (skin-perm)	Yes	No Flow Constant Pressure
Finite Conductivity Fracture (Vertical Well)	No	No Flow
Uniform Flux Fracture (Vertical Well)	Yes	No Flow
MFHW	Yes	No Flow Constant Pressure
Radial Composite	Yes	No Flow Constant Pressure
Closed Linear Reservoir	Yes	No Flow Constant Pressure
Multi Fractured Horizontal Well	Yes	No Flow Constant Pressure

autoFMB

The automation capabilities of AFA extend to include automated Flowing Material Balance (autoFMB). The AFA platform automatically evaluates P10, P50, and P90 (low, mid, and high) scenarios for Original Gas in Place (OGIP), productivity, reservoir flow capacity, and more. Within the AFA™ platform, three full Flowing Material Balances (FMB) are simultaneously analyzed, providing comprehensive and efficient assessments of reservoir performance.
