Hop On! Trainings

What is a Hop On! Training? It is a short remote training session focused on one specific theme. The instructor will lead all attendees through the different concepts needed prior to practicing with real data on hands-on exercises using our software solutions: PLATO, PLATO-AT, PLATO-DTS.

Each session is independent*, meaning you can join whenever you find a session that suits your needs. It is an easy way to refresh your knowledge or learn new skills!

Agenda

You will find below the list of upcoming Hop on! Training sessions for 2023. Make sure you visit the page frequently as it will be regularly updated.

• April 14^th – Interpretation of DTS data (1/2): perform a simple DTS analysis over a stable flow period

The instructor will go over the theory of DTS data and temperature analysis.
The attendees will learn how to prepare the data for analysis. They will be able to identify and perform DTS data drift correction using multiple methods. They will also learn how to differentiate between stable and transitional periods from a temperature point-of-view and the influence of the well’s conditions on the analysis. The instructor will demonstrate how to perform a historical cumulative DTS analysis over a 400-days period. They will also go over the monitoring and automatic processing capabilities of the software.

At the end of the session, the class will have acquired the skills to identify a suitable stable flow period, adjust the geothermal temperature, and choose the inflow zones to perform a successful quantitative DTS analysis.

• May 5^th – Interpretation of DTS data (2/2): perform a Gas-Water DTS analysis

The instructor will guide the attendees through a DTS analysis using a 2-phase gas producer real DTS data. The attendees will learn how to prepare the data, then will go over the step-by-step workflow of PLATO-DTS to perform the analysis:

Data QC: DTS data QC; caliper, survey and perforation/completion import; stable flow period identification.

Corrections : 

PreProcess: Effective flowing temperature calculation (Twf); TVD calculation; Pressure calculation using reference point and gradient; Geotherm calculation and reservoir information setting.

Profile: Manual inflow zones determination from real DTS data.

Process: Manipulation of geothermal; zoning of rock conductivity; Adjustment of surface rate and continuity constraints; Convergence of reservoir and well pressure; Manipulation of flow rate boundaries.

PostProcess:

The attendees will finally be introduced to automatic report generation.

• May 26^th – Warmback Analysis: Conventional reservoir open-hole injectors (cylindrical warmback)

The instructor will introduce the different injection models the attendees may come across and will explain how to identify which injectors are more suited to a warmback analysis using DTS data. This session will focus on traditional warmback datasets for open-hole injectors in conventional reservoir. The attendees will be introduced to the warmback cylindrical model directly derived from the enthalpy conservation equation.

An open-hole water injector warmback real dataset will be used by the class to practice using the warmback model. The attendees will learn how the temperature behaves during warmback and how to relate the warmback gradient to injection rates.

• June 9^th – Working with geothermal : Learn how to use the Tgeo Auto method

The geothermal is an essential element of the temperature modeling. It represents the temperature at which the fluids are being produced into the well as well as the influence of the reservoir on the wellbore. In simple cases, the geothermal can be inferred from a bottom hole temperature datapoint, general knowledge of the region and/or a measurement of temperature below the first inflow zone. But, often, it is not that simple and the thermal properties of the reservoir or the completion will modify the geothermal temperature. In the first exercise, the instructor will walk the attendees through the different parameters available to properly model the geothermal in PLATO.

In the most challenging wells, such as the wells stimulated with hydraulic fracturing, the geothermal cannot be estimated with traditional technique and general thermal parametrization will fall short. The geothermal cannot be directly measured and needs to be optimized. In the second exercise the attendees will learn how to use the Geotherm Automation functionality of PLATO-DTS to optimize the geothermal needed to perform a Production Logging analysis with a HF DTS dataset.

• June 30^th – PLATO Beginner practice: learn basic production logging with spinners

The instructor will explain the philosophy behind PLATO and its renowned Global Optimization approach. The 6-step workflow will be introduced to the attendees through a demo double with a hands-on practice exercise. The attendees will become familiar with the basic steps needed for a spinner-based analysis. They will then undertake two additional exercises to practice their newly acquired skills.

The first exercise will introduce the concepts of cross-flow and static water column. The attendees will learn how to analyze a 2-phase producer with cross-flow.

The second exercise will allow the attendees to practice their Profile In the last exercise, trainees will be guided to analyze water injection real data to perform an injection well analysis.

• Aug 11^th – Advanced multirate analysis: Estimate reservoir pressure and productivity index

In this session the trainee will learn first how to create a par file for each rate using a dedicated template.

Then, the instructor will lead the trainee through a hands-on exercise where he will go over all required steps to perform such analysis. The attendee will learn the different steps and purpose of the workflow:

Data QC and mapping: How to map the velocity and capacitance data, and add specification of the perforations manually

PreProcess: How to select the passes for each rate

Spinner Calibration: How to add the layers on Spinner Cross-plots

Profile Building

Process: How to use waterflow to specify a static water column

PostProcess: edition of multirate parameters to be saved to par file.

Ultimately the trainee will export the final tables to perform the SIP analysis.

• August 25^th –DTS (Advanced) : Perform advanced simulations to analyze hydraulic fractured wells.

In this session the instructor will lead the students through three hands-on exercises.

In the first one, trainees will learn how to constrain the thermal model using flowrates bounds set on the zonal production rates during optimization.

In the second exercise, the instructor will guide the trainees during a complex well scenario using simulations to determine DTS feasibility tests.

In the third and last exercise of the session, the instructor will lead the trainees through the analysis of a 3-phase, fracked, horizontal well. Trainees will constrain both the Gas Water Ration and Gas Oil Ratio, and use the flow boundaries parameter to compute the geotherm automation.

• September 8^th – Combining DAS and DTS (Advanced): combine DAS and DTS data to identify production zones and determine production profiles

The instructor will first review how to process DAS and DTS data: the attendee will correlate start by correlating depth and time and then will review the event log.

Then, the instructor will lead the trainees through a qualitative analysis of DTS and DAS data and they will learn how to:

Shift depth and time data

Synchronize DAS and DTS data

Identify fracked stages out of Frequency Spectra

Identify production zones from DAS

Find a correspondence between DAS and DTS data.

Perform a quantitative analysis of DTS data using imported deviation, perforations, and geothermal data.

Build a production profile using the qualitative results found at the previous step.

• September 29^th – PLATO interface manipulation and GUI: learn how to customize PLATO for a tailored experience

The instructor will teach first how to manipulate Figurines:

Polylines: How to create, edit, move, delete, and save polylines.

Depth Anchors: Learn how to differentiate depth matching and depth shifting and how to select, move, and delete anchors.

Curves: How to select, set an offset, shift, draw, save, or restore the curves.

Animation: How to play, pause, reverse, speed up, slow down, or reset the animation.

You will also learn how to create in your project new plots such as Curve, Histogram, Cross, and Station Plots and to add Layers.
