SpecialReport: Compression & Production Optimization

Analysis And Reporting
The collected information must be analyzed carefully for operations (e.g., subbasins, gathering line ownership, singleversus-multiwell pad), equipment and reporting exemptions, since calculations
vary from emission factors to complex
equations that require a detailed understanding of equipment and its operation.

The information must be quality-checked
by persons knowledgeable of oil and gas
operations and the latest reporting requirements to ensure it is recent and relevant, as well as within guideline values.
In addition, the tools developed to calculate GHG emissions and house data must
be revised to incorporate the latest calculation
methods and equipment to ensure calculations are accurate and reflect current conditions. Analysis requirements are similar

for sizes of systems, and include:
* Identifying equipment and operations (pipeline gas-to-oil ratios, operation
and vacuum, single- or multiple-well pad,
etc.) within each basin, and determine
ownership (gathering lines);
* Establishing terminology and units
for equipment and operation information,
data collection formats, and datasets that
will be shared;
* Segregating equipment and operations

tracking and analysis.
Small producers with tens of wells
such as EdgeMarc Energy, which holds
52,000 total acres under lease in Pennsylvania and Ohio and has drilled about
50 Marcellus and Utica wells to date,
may be able to use a spreadsheet to
collect and calculate emissions and track
data. However, larger producers with hundreds or thousands of wells, transporters,
and processors may require elaborate
systems to accomplish the same task.
Regardless of the system size, the approach is similar and can be defined by
three main steps: data collection, analysis,
and reporting.
The initial step is to identify sources
that can provide data to address the GHG
reporting rule and demonstrate compliance.
Because of an oil and gas company's
distinct function groups, it is important
to first understand what information each
function group collects and how it is
maintained. Initially, not only may it be
difficult to collect data, but the information
can be conflicting, since different function
groups may have similar data. Also,
groups may use different terminology
and units for the same data.
Therefore, one must define terms and
units for data collection and transfer between departments. Potential problems
typically are related to duplicate data, incorrect units, operating status, and missing
components. The focus at this step is to
ensure necessary data can be bridged
into a centralized database that includes:
* Number of wells on a well pad and
location by basin;
* Equipment such as gathering lines,
wells, engines, compressors and separators;
* Production information, including
sub-basins and production rates;
* Operational information such as blowdowns, engines hours, and gas analysis;
* Other information such as ownership, completions, workovers, fuel usage
and leakage;
* Leak detection; and
* Scheduling of events such as shutins, flowbacks, flaring, etc.
