In-Well Fiber-Optic Sensing

Disciplines: Engineering
Category: Foundational • Completion • Production • Drilling • Well Integrity • Reservoir Characterization • Mapping
Format: Classroom • Live Online
Available: Public • Private

Who Should Attend

Completion, drilling, production, surveillance, and reservoir engineers who need an introduction to the design and use of fiber-optic instrumented well installations, as well as geologists and geophysicists who need an understanding of the capabilities of in-well fiber-optic sensing.

Description

This two-day training event introduces petroleum engineers and geoscientists to fiber-optic sensing technology that is used for well and reservoir diagnostics and surveillance. Each day may be taken individually to satisfy a particular need (technology awareness, review prior to beginning FO field projects, introduction to current preferred practices) or as a sequence to obtain a more thorough understanding (to move user through “awareness” to “knowledgeable” level).

Learning Outcomes

How fiber-optic sensors work.
Where and how fiber-optic sensing can create value.
Technical and economic factors that influence the selection and justification for installing DAS/DTS systems in specific well types.
Completion and monitoring components needed to deliver a DAS/DTS-monitored well.
Installation and commissioning operations.

Course Content

1. In-Well Fiber-Optic Sensing: Introduction to the Technology and Applications (1 Day)

What is Fiber-Optic Sensing (FOS): basic physics and engineering of the FOS system components: fibers, coatings, cabling, connectors optical fibers, sensor types, instrumentation.
Why we would want to use FOS: advantages and disadvantages vs. other sensing/monitoring technologies.
1. Single-point FO sensors: P, T, seismic/acoustic
2. Distributed FO sensing: temperature (DTS), acoustics (DAS), strain (DSS)

Overview of the different applications
Survey of FOS system deployment methods
1. Permanently installed FOS
2. FO “logging” interventions & temporary installations

Data management and analysis/interpretation
Factors that influence FOS system selection
High-level screening of candidate wells and justification for installing FOS

2. In-Well Fiber-Optic Sensing: Applications and Deployment (1 Day)

Applications for Diagnostics and Surveillance

Introduction to “Life-of-Field” monitoring with Fiber-Optic Sensing (FOS)
Using FOS for completion and stimulation diagnostics, e.g.:
1. Role in field development
2. Well placement strategy/optimization (2- and 3-d)
3. Stage and cluster efficiency
4. Frac monitoring/mapping
5. Frac “hits”

Life-of-field surveillance
1. Production monitoring/multiphase inflow profiling
2. Well-well interactions
3. Artificial lift monitoring
4. Well integrity

What FOS provides (where it works), what it misses (advantages/disadvantages vs. other monitoring tools)

Integration (synergy) with other monitoring methods
1. Tracers

TRANSFERS: If a student elects to apply their registration fee to a different course, notification of the transfer must be received at least two (2) weeks prior to the original course start date.
SUBSTITUTIONS: Substituting a student for another is accepted without penalty if notification is received at least seven (7) days prior to the course start date. In addition, SCA reserves the right to substitute course instructors as necessary.
CANCELLATIONS & REFUNDS: If it is necessary to cancel an enrollment, the tuition, less the non-refundable registration fee of US $150.00, will be reimbursed provided the cancellation is received in our office at least 30 days prior to the first day of class. For cancellations received less than 30 days in advance, the full tuition is due. SCA reserves the right to cancel any course session at any time. The final decision to hold a course is typically made two weeks prior to the scheduled start date. If a course is canceled, registrants will be notified via email and given the opportunity to transfer to another course or receive a refund. NOTE: Should there be a difference in the tuition, the difference will be refunded on or before the start of the class. SCA is not responsible for any penalties incurred for having to cancel or change your own travel arrangements. Please keep our cancellation policy in mind when planning your travel.
