ManyWells: simulation of multiphase flow in thousands of wells

The ManyWells datasets contain simulations of multiphase (gas, oil, water) flow in thousands of wells. The datasets were created and shared by Solution Seeker AS to support research on data-driven methodologies and industrial applications of machine learning and AI.

Description of datasets

There are currently three datasets for three different operating conditions:

• manywells-sol-1: simulations with stationary boundary conditions and open-loop control (no feedback)
• manywells-nsol-1: simulations with non-stationary boundary conditions and open-loop control (no feedback)
• manywells-nscl-1: simulations with non-stationary boundary conditions and closed-loop control (with feedback)

Each dataset has one million data points from 2000 vertical wells (500 data points per well). Each data point corresponds to one simulation performed by the simulator code in the ManyWells GitHub repository.

The datasets include a feature called "ID", which uniquely identifies a wells. Please note that ID are unique only within each dataset, meaning that well 1 in dataset A is different from well 1 in dataset B.

The parameters used in the simulation can be found in the config files, named [dataset-name]_config.zip. The configuration is stored as a dictionary with the keys being the well IDs.

Dataset features

Feature	Description	Unit
ID	Unique well ID	-
CHK	Choke position in [0, 1]	-
PBH	Pressure bottomhole	bar
PWH	Pressure wellhead	bar
PDC	Pressure downstream choke	bar
TBH	Temperature bottomhole	K
TWH	Temperature wellhead	K
WGL	Mass flow rate, lift gas	kg/s
WGAS	Mass flow rate, gas excl. lift gas	kg/s
WLIQ	Mass flow rate, liquid	kg/s
WOIL	Mass flow rate, oil	kg/s
WWAT	Mass flow rate, water	kg/s
WTOT	Mass flow rate, total incl. lift gas	kg/s
QGL	Volumetric flow rate at standard conditions, lift gas	Sm³/h
QGAS	Volumetric flow rate at standard conditions, gas excl. lift gas	Sm³/h
QLIQ	Volumetric flow rate at standard conditions, liquid	Sm³/h
QOIL	Volumetric flow rate at standard conditions, oil	Sm³/h
QWAT	Volumetric flow rate at standard conditions, water	Sm³/h
QTOT	Volumetric flow rate at standard conditions, total incl. lift gas	Sm³/h
FGAS	Inflow gas mass fraction	-
FOIL	Inflow oil mass fraction	-
FWAT	Inflow water mass fraction	-
WEEKS	Weeks since first data point	7d
CHOKED	Boolean indicating if flow is choked	-
FRBH	Flow regime at bottomhole (represented by string)	-
FRWH	Flow regime at wellhead (represented by string)	-

The following relations apply:

• WLIQ = WOIL + WWAT
• WTOT = WLIQ + WGAS + WGL
• QLIQ = QOIL + QWAT
• QTOT = QLIQ + QGAS + QGL

The flow regime features, FRBH and FRWH, may take on one of the following string values: 'bubbly', 'slug-churn', 'annular'.

The WEEKS feature is only present in non-stationary datasets (manywells-nsol-1 and manywells-nscl-1).

Personal and sensitive information

The datasets do not contain any personal, sensitive, or private data.

How to use the data?

The following snippet shows how to use the HuggingFace datasets package to download the dataset in Python.

import datasets

# Download 'manywells-sol-1'
data = datasets.load_dataset("solution-seeker-as/manywells", name='manywells-sol-1')

# Cast dataset to a Pandas DataFrame
df = data['train'].to_pandas()

# Print the data
print(df)
