Tracer Case Study

Reservoir fl uid in-fl ow measurement from a tight oil fi eld development

RESERVOIR CHARACTERISATION

The Project

A customer requested a Tracerco fracture fl ow study that

would allow oil in-fl ow behavior to be measured following

completion of an unconventional well to better understand

contribution from each stimulated interval.

Sixteen unique organic based tracers were selected

for the project. Each tracer was injected at the leading

edge of individual hydraulic fracture stages when fi rst

solids were added to the hydraulic fl uids in order that the

tracer would penetrate deep into the fracture structure

and make contact with formation oil. During stimulation

treatment, stage three was abandoned due to operational

issues. Subsequent back fl ow of the well and analysis

of tracer presence in oil samples allowed relative oil fl ow

contribution from each stage to be measured.

Well Specifi cation

The horizontal oil well at 2km 928mTVD was located in

the Eagle Ford Shale and it was planned to carry out a 16

stage hydraulic fracture program. These would be evenly

distributed along the well bore length at 300 feet intervals.

Tracerco Technology

The specialist oil based tracers have a high affi nity for

oil and are very insoluble in water. As such they readily

partition from the water into the oil phase upon contact

with reservoir oil and allow the source of oil fl ow to be

determined. The technology also allows confi rmation

that fl ow is occurring from the toe end of a well through

downhole equipment after stimulation activities have been

completed.

Sampling

Following completion of the stimulation the well was

fl owed to clean up and start production. 25ml samples of

oil were collected on a regular basis and analysis for tracer

presence carried out using specialist equipment.

Results

Results reveal initial oil fl ow from stages closer to the heel

of the well with mid point being very low and toe fl ow

response from only the last two stages. As fl ow continues,

toe fl ow overall contribution increases but mid well fl ow

continues to be relatively low with as many as four stages

contributing zero to the overall production. The results are

shown overleaf.9500
