Procedure of Testing Of Well Liquids

Liquid Loading Test

The following is a step by step easy method to determine if a Soap-Condensate-Asphaltene-Paraffin stick will serve its purpose to rectify the liquid loading of wells.

Step 1: Obtain from well 1 to 2 Litres of well liquids from the desired well and run the tests as specified in what is to be accomplished to resolve the issues. (Well loading, asphaltenes, paraffin’s, salt, scale etc.)

Step 2: Melt the desired stick or sticks (3 inches of stick based on 1 ¼ inch stick)(each in a separate container) into 500ml of fresh water, this usually happens by putting the 3 inch of stick in warm or hot water and dissolves overnight with no agitation (the hotter the water the quicker the stick dissolves). In the case of combination sticks like the SlickWillie 1 ½ inches of each is desired)

Step 3: Useing a 1 Litre bottle fill it approximeitly ¼ full of the produced fluid sample (this step is for consideration of lift and drop out looking at how much a head of foam is created and how fast the liquid returns to fluid form.) Add 7-10 drops of the solution that was created by melting the stick in water as specified. When the two are together shake vigorously 10-20 times to create the agitation for test purposed (note in a lab a blender can be used as opposed to a 1 Litre bottle).

Step 4: Note the height of foam created whereas if bottle is full we have 100 plus foam height. Also note at this time the amount of water absorbed and look at how fast the foam is dissipating and returning to liquid form. Each stick can react differently in different water samples and note these on a spread sheet (included). This will give you which sticks can achieve the desired lift of fluids you require. Also remember the deeper the well we would like to see the half-life (amount of time we see bubbles returning to liquid) to be longer so we bring up the maximum amount of fluids from the well.

 

In conclusion over the years this has been the best method I have found to see if we have a stick that works. As this is visual and not done in a well enviroment it may not work but over 25 years of experience that is less than a 5% chance. When they do testing in a Lab (Costly) in many cases they do not get the right mixture as when treating a well there is no way possible of replicating downhole conditions.

Therefore i have for over 20 years used this method and achieved great success in enhancing production and cleaning out problem wells. We always look at cost of treatment in relation to production increase and with this method as we are only treating the wells as required (when the well start to load or create problems) we are only interducing the fix when it has issues keeping cost to a minimum.

Unlike a Liquid a stick will fall to the bottom of the formation therefore treating a well from the bottomup as opposed to just doing the surface whch happens with a liquid. A stick is designed to stat dessolving when it comes in contact with the fluid colum, but dependant on tempureature and amount of gas bubbling through the fluids can take anywhere from 5 minute (Kwik N Dry) to 45 minutes or longer to totally dissovle based on the type of liquid produced by the well.
