Microbial and Fines Migration

Microbial

Tomson Technologies researches ways to mitigate microbial activity in the oilfield. Through field sampling, analysis, and biocide testing Tomson Technologies implements site-wide and company-wide microbiology treatment strategies.

Microbial analysis plays an important role in production well flow assurance. Several microbial processes can have a profound impact on oil and gas production and downstream processing, as well as on water quality and safety. Therefore, for environmental, health and economic reasons, it is critical for reservoir engineers and operators to understand how individual decisions and actions related to drilling, fracturing, and well operation may affect subsurface microbial community dynamics and composition.

Tomson can perform bug bottles for kill rate analysis as well as detailed quantification of the microbial community via qPCR.

Fines Migration

Core1Fines migration in the reservoir can be caused by a number of factors, including frequent squeeze treatments, injection, flow rate changes, salinity changes, and other factors. Migration of fines from the reservoir creates a serious flow assurance risk by choking pore throats and reducing permeability. Near-wellbore damage is frequently seen as a direct effect of fines migration. Reducing fines migration is typically accomplished through either preventing fines from migrating initially or from dispersing the already-created fines in order to produce them through the wellbore. Fines migration is a complicated problem with several sources and solution approaches. Tomson Technologies has extensive expertise and research on particular fines migration problems and provides custom solutions to overcome individual fines migration issues.
