SpecialReport: Crude Purchasing
site, or increasingly, at central facilities.
Separators, heater treaters and stabilizing
towers increase temperature and decrease
pressure to allow the gas molecules to
separate, according to Anson. This processing equipment breaks out as much
gas as possible before the crude goes to
sales or custody transfer. If the gas hydrocarbons are not liberated from the oil,
he says, the measurement equipment may
over-register the actual liquid volume
and experience volumetric shrinkage once
all of the gas is liberated.
Blended oil can also lead to measurement anomalies. " Smaller hydrocarbon
molecules in one source can embed between larger molecules from another, creating the potential for a lower combined
volume than expected, " notes Anson. For
example, he says two 100-barrel batches
of unblended crude may measure 199
barrels after blending, creating volumetric
shrinkage from blending.
For all its importance at the point of
custody transfer, measurement data often
is not accurately or efficiently transferred
to data management systems, Anson
states. " Just like there are different measurement technologies, there are different
data management scenarios, " he avers.
" It can be as simple as a pumper typing
data into a spreadsheet or a trucker leaving
paper tickets in mason jars, both of which
easily introduce errors, cause delays and
create a big burden for reporting given
the volume of data involved. "
Capturing data at the point of measurement and transmitting it by SCADA
makes great sense, given the importance
of the data for allocation, accounting, reporting and planning, Anson goes on. To
that end, W Energy Software is developing
new technologies to ease field-level data
capture, whether manually entered, imported from spreadsheets or delivered as
digital data.
" Our goal is to enable the analysts in
the office to go through the data more
quickly and accurately, " he says. " They
will be able to look at suspect data first
by setting smart parameters for their data
and then making corrections and adjustments as needed. "
" Producers in shale plays are moving
large volumes, so even very small errors
can lead to large sums of money, " Anson
points out. " We want to help them ensure
their data has a high level of integrity all
the way from measurement to final downstream reporting. "

Reporting, accounting, regulatory and
forecasting are all spaces that rely on
measurement data, he adds. Engineering
groups use the information to make decisions on working over wells or shutting
in production. " Measurement data is used
in almost every part of the business. "
As the industry continues to do more
with less, efficient data management is

gaining urgency, Anson concludes.
" When you are looking at tens of thousands of records of data, it is easy to
miss things that contribute to overall
losses, " he says. " Look for next-generation measurement data management to
allow users to track, validate, balance
and report hydrocarbon quantity and
quality data across the value chain. " ❒

Regardless of whether the end user is a producer or midstream or pipeline company,
the primary value driver behind LACT units is improved revenue capture. LACT units automatically measure temperature, pressure, gravity, flow and other variables to eliminate
the volumetric " shrinkage factor " associated with manual custody transfer measurements and increase sales revenues even in lower-volume applications.
