Where do companies get their analog information?
From various sources, according to survey responses.
Some answers: data purchased from third parties,
literature searches, databases and consortia studies.
Half the companies interviewed have purchased an
analog database system, and five companies are building custom in-house
digital analog systems.
“We thought the super majors would have similar in-house
analog systems in place, but we were surprised to find that is not
the case,” Wan said. “None of those (surveyed) companies have an
in-house system.”
There are likely many reasons for this, Wan said,
including:
- The flux in the industry created by mergers
and acquisitions. - Movements of personnel from one project
area to another. - An emphasis on finding and producing oil
and gas rather than documenting and compiling data.
“Systematic documenting
and codifying information and building a system to house that data
would require a major commitment,” Wan said. “Most companies indicated
they could get the data from public libraries or third party providers.”
Some even take field trips.
Bonus
Inclusion:
Survey participants made several recommendations to improve the
application of geological analogs. These include:
- Documenting and publishing best practices.
- Establishing a consortium to fund the creation of a methodology
for integrating seismic analog information with outcrop and subsurface
geological data and engineering data. - More education to convince a greater number of production
geologists and reservoir engineers that decisions based solely on
“closeology” methods may not be optimum.
