Hot Oil Problems

Mon, 09 Mar 2009 00:00:00 -0700

One of the main problems with using hot oil for paraffin removal, is that it can actually induce formation damage into the well [1].

During regular operations, stock tank oil is heated to a fairly high temperature (above 120°C, 250°F) and injected into the annulus of the wellbore between the casing and the tubing. As the hot oil descends, the temperature drops rapidly as the heat is drawn away by the surface area of the tubing.

Straub[2] presents an actual example where a hot oil treatment failed to raise the bottomhole temperature and had actually reduced the temperature from 52°C down to 46°C. Temperature changes such as these can actually cause deposition of paraffin downhole. The same hot oil treatment intended to remove paraffin, can actually cause paraffin to be deposited.

New Web Site

Parasolve announced the launch of their new web site today. The new web site uses state-of-the-art CMS technology to provide better coverage of their oil field service operations allowing the oil industry to make more informed decisions on alternatives to dangerous chemicals and procedures previously used in oil well services.

In an interview with Tyler Gobin (vice-president of Parasolve), Tyler reveals Parasolve's goals to clean-up the industry. "Our plan is to make as many people as possible in the oil industry aware that there are safer alternatives for oil well servicing, every bit as effective as dangerous chemicals."

Over the past years Parasolve has established itself as a leader in environmentally friendly oil field services from their head office in Calgary Alberta. Under pressure from both the provincial and federal governments as well as green parties across North America, oil producers are starting to listen and take notice that it's time for a change.

Parasolve's future includes expansion into the US beginning with a branch office in Texas. Both the industry and environmental protection advocates applaud the move saying "It's about time, something that should have began long ago is finally under way." We can look forward to a cleaner and safer oil production industry thanks to the efforts of people like Parasolve, and a safer and greener future for our children.
