Reservoir fluid sampling & analysis techniques
Details :
Reservoir fluid sampling and analysis is one of the most
delicate and crucial services that strongly impact the reservoir management during
each stage of the entire reservoir life cycle. In many historical cases, lack
of knowledge about the reservoir fluid has led to an inappropriate production
strategy, wrong sizing of surface facilities, ineffective field development
plan, and environmental or HSE consequences. Losses were huge and unrecoverable.
This course provides reservoir fluid in-charge engineers with the essential
knowledge required to capture a meaningful and representative reservoir fluid
samples and eliminate operational mistakes that may lead to loss of accurate fluid modeling.
The course starts with the background on the phase behavior for
the different reservoir fluids and how this will impact the sampling technique selection and the application of
sampling operational procedure.
The course is covering all sampling techniques including WL
open hole samples, WL or DST conveyed cased hole sampling, well head sampling,
and separator sampling. for each sampling technique the recommended samples
practices, equipment used, operational procedures, samples QC with advantages
and disadvantages will be discussed.
The course also covers in brief the PVT experiments normally
conducted in the laboratory and provides details about the procedure and the
data to be obtained out of each test.
By end of this training course, the participants are
expected to be able to acquire the following knowledge:
1. Understand sampling Objectives and application of
reservoir fluid sampling and analysis
2. Factors affecting representative sampling
3. Selecting an effective Sampling Method
4. Understand all different sampling methods with
the following criterions:
·
Equipment used
·
Operational guidelines and
well conditioning procedure
·
Validation and quality
control of captured samples (onsite and in PVT lab)
·
Challenges and common
mistakes that affect quality of samples
·
Case studies
5.
Basic knowledge about all
PVT experiments and obtained data.
