The amount of the initial application of Custom PF and the amount of regular treatments will be relative to the well conditions. The primary conditions that determine the treatment procedure are 1) the severity of the paraffin problem, and 2) the well maintenance frequency. A treatability study may be needed to determine the proper treatment schedule for Custom PF.
Importantly, the entire treatment procedure is based on preventative maintenance rather than emergency workovers. For best results, start with a well that has just been cleaned or has been worked over. Custom PF is a paraffin inhibitor, designed to control paraffin buildup; it is not a chemical emulsifier.
There are several ways to apply Custom PF to the well. Initially, Custom PF can be pumper under pressure into the well. To maintain the well, Custom PF can be pumped into the well annulus through the annulus valve. Custom PF can be applied to the well by an electric or gas operated pump. In most cases, little or no modification of the wellhead plumbing is required to accommodate the treatment equipment.
If you are using a biocide to control sulfate reducing bacteria (SRB), then you will need to move the biocide injection point from the downhole to the wellhead. Also, in many cases you can reduce the amount of biocide injected by as much as 33% and still not have any additional corrosion problems.
Daily production is not affected, as opposed to hot oiling, because lengthy recirculation times are not required. Plus, produced from the storage tanks and not used as a transport media.
Custom PF, manufacture and distributed by Custom Biologicals, is designed as a biological paraffin inhibitor.
