What are Capillary StringsWhat are Capillary Strings

?High strength duplex alloy continuous tubing, 1/4, 3/8, or

5/8 diameter?The Capillary String is injected through the wellhead and into

the production tubing

?The Capillary String can be deployed while the well is flowing

?No work-over rig is required.

?The well is not killed or damaged during the installation

?The Capillary String can be left hanging in the wellbore

? Installation depths up to 22,000 feet

?System can be removed and re-installed in another well


4/52

Capillary String Applications and CapabilitiesCapillary String Applications and Capabilities

?Relieve water or hydrocarbon loading problems

?Reduce corrosion, scale, paraffin or hydrate problems.

? Foam assisted gas lifting

?Chemical or acid washes

?Relocate the lowest gas lift injection point

?Re-instate SCSSV control line failures.

Scale Solubility Test:


33/52

Scale Solubility Test:Test were conducted with 15% Acetic and Techni-Solv 1780 solutions at 350F at

1000 psi and 15% HCL at 75F and atmospheric pressure. Samples of CaCO3 wereplaced into 80 milliliters of each test solution for a minimum of 4 hrs and heated and

pressured as required to meet the test objectives. After 4 hrs the treating fluids and

remaining solids were filtered, washed and then allowed to dry. The remainingsolids were then calculated and the percent of solids dissolved were calculated.
