Scope of Work

With its state of the art equipment and extensive years of personnel experience, PICO Energy’s CTS  brings to its customers superior solutions with outstanding service delivery at their fingertips.

Our portfolio offers a wide range of field equipment, software, acquisition systems and chemical solutions engineered and delivered to clients’ locations wherever it would be.

Lifting Services

The injection of nitrogen into the fluid column within the production conduit to initiate fluid flow from the wellbore and production from the reservoir. Nitrogen lifting through a coiled tubing string is a common technique used in well kickoff.

Displacement Services

The injection of nitrogen into the fluid column in a pull-heading technique to displace the killing fluid to get the well into an underbalance condition.


The removal of wellbore-fill material, such as sand, scale or organic materials, and other debris from the wellbore. Many reservoirs produce some sand or fines that may not be carried to surface in the produced fluid. Accumulations of fill material may eventually increase in concentration within thelower wellbore, possibly restricting production. Clean out may be for (sand-scale, etc…), usually using nitrified gel.

Acid Stimulation

The treatment of a reservoir formation with a fluid containing a reactive acid. the matrix acidizing treatment improves the formation permeability to enable enhanced production of reservoir fluids. At treatment pressures below the fracture pressure of the formation. The coiled tubing enables a good jetting and penetration condition in the exact wanted area while avoiding the formation damage.

Scale Removal & Inhibition

Scale-inhibition treatments involve squeezing a chemical inhibitor into a water-producing zone for subsequent commingling with produced fluids, preventing further scale precipitation. Chemical removal is performed with different solvents according to the type of scale: Carbonate scales such as calcium carbonate or calcite [CaCO3] can be readily dissolved with hydrochloric acid.

Acid Wash

A wellbore acid treatment designed to remove scale or similar deposits from perforations and well-completion components. Acid-wash treatments generally do not include injection of treatment fluid into the reservoir formation, can be applied using both through tubing or pull heading techniques.


Coiled Tubing has the ability to perform drilling and milling operations under live well conditions with the assistance of positive displacement motors (PDM’s). Coiled Tubing provides an ability to mill formation in an under balance or balanced condition while preventing damage to the formation from drilling fluids.


The application of technique using fishing tools for the removal of junk, or fish from a wellbore. The key elements of a fishing operation include an understanding of the dimensions and nature of the fish to be removed, the wellbore conditions, the tools and techniques employed and the process by which the recovered fish will be handled at surface.
