First ResponseWhy was First Response Developed?
Turbo-Chem International was approached by a major operator to research and develop a one
sack solution to partial to massive losses while drilling offshore with oil & synthetic base mud
systems. While there are a few “One Sack Solutions” currently on the market and being used, they
are not performing at a rate deemed successful by the operator. During TCI’s research of
hundreds and thousands of wells in which our patented products were being used together with
synergistic success to stop partial to massive losses, a trend was evident. That because
Oil/Synthetic base mud systems and Water base Mud systems react vastly different when adding
LCM to the respective drilling fluids, what may work well in a water base mud system at a certain
ppb, may not address the loss circulation issues when using Oil/Synthetic base muds. Taking this
into consideration, TCI started a rigorous Research and Development project to tackle this issue.

How was First Response Developed?
TCI’s Research and Development team spent months testing and evaluating the perfect
combination of materials that would give the optimum particle size range to solve partial to
massive losses due to fractures. Whenever the optimum blends of products were determined,
testing began. Numerous particle plugging tests were performed using stainless steel slotted discs.
These tests were run at low pressure using Modified Particle Plugging discs specifically designed by
TCI for use in the API Press (100 psi max), Dynamic PPT’s (500 PSI Max) and Static PPT’s (up to 5000
psi). In addition to slotted discs, semi-permeable mediums were used in the cells, as well such as
various size gravel, to ensure the sealing capabilities of the First Response pill.

How does the First Response differ from other lost circulation materials?
TCI’s First Response pill is extremely versatile as a preventative used in sweeps or as a pill when the
well dictates a need for hole healing or soft squeezing. Contrary to other “single sack” LCM’s on
the market, First Response contains NO inert materials. All of the products contained in First
Response are environmentally friendly and are specifically designed to be used in most well
specific applications.

What are the benefits of running First Response on my well?
First response can be added to all oil or synthetic based mud systems. First Response can also save
on rig space, whereas other LCM’s need to be run in conjunction with as many as 4 or 5 additional
various particle sized palleted materials. TCI’s unique, proprietary one sack blend can be added,
as dictated by the well, in varied amounts from 15 ppb – 60 ppb. First response has been used
successfully in West Texas and recently as a 50 bbl pill at only 25 ppb in the Eagleford Formation.
First Response is aptly named because in many cases it can be used as a First Line of defense
when initial losses occur, rather than running a High Solids Squeeze pill which in some cases can be
time consuming and more costly, First Response may be spotted as a pill and soft squeezed into a
losing formation.
