One of the most critical jobs of an oil field service company in Duchesne County is to oversee cases of well abandonment, in all of their forms. A seasoned service company will know how to identify the type of abandonment and what needs to be done to make sure it progresses smoothly and, most importantly, so that no lasting environmental concerns make themselves apparent post-abandonment.
The first and most common form of well abandonment is temporary abandonment. Temporary abandonment can occur for a number of reasons, including:
- During longer shutdowns due to company focus, fiscal barriers or regulatory disputes.
- As an oilfield is being redeveloped, to accommodate additional wells.
- While a specific site is awaiting a workover.
As the name implies, it’s the intent of a company to re-open a temporarily abandoned well sometime in the near future, in a period of between six months and two years. The inactivity of a given situation will force the need to be appropriately sealed, however, since a lack of presence on the jobsite could create unmonitored issues.
In this instance, an oil field service company in Duchesne County would be called in to plug the well to prevent cross-flow and continued production. Plugging a temporarily abandoned well will also serve to protect the well from depressurization.
Plugged and abandoned
When a well has been exhausted and needs to be closed for good, it’s a “plugged and abandoned” situation. This procedure effectively decommissions a well in a way that’s environmentally sound and should only be undertaken at the very end of economic operations.
For this procedure, the well is cemented, with mechanical plugs inset to prevent cross flows and any residual production. Permanent plugs also require a sizeable amount of pre-planning, as they’re required to meet the demands of municipal regulations in regards to oilfield pump operations—most specifically well decommissioning.
So what all goes into well plugs? It’s more than just cement being pumped into the ground! There are actually a number of considerations that must be made to ensure plugs meet the many specifications that they’ll be held to by governing bodies, including pressure testing and well identification logging and markings. Again, a seasoned oil field service company in Duchesne County will be required to make sure the plug falls within specifications.
Proper well decommissioning or plugging all boils down to one chief concern: what happens to improperly plugged wells? That answer can be varied, although the results are undesirable no matter what form they take:
- Contaminated soil and groundwater
- Leakage into aquifers, destroying the water table
- Open well entrances, posing dangers for local wildlife
If a plug fails, the drilling and pumping company can be held liable for detrimental damages. The need for comprehensive service from a seasoned oil field service company in Duchesne County is imperative and shouldn’t be overlooked when the time comes to plug a well, whether for temporary abandonment or permanent decommissioning.
