The first industrial use of Geothermal Energy dates back to Larderello, Italy in 1911 with a geothermal power plant and 1911 sets also the year of Lamberti’s foundation in Italy.

For more than a hundred years we have been innovating, designing, tailoring molecules and ready to use products to be sustainable and cost effective for our business partners.We have a long history of supplying the right chemicals to drill geothermal wells and handle the produced geothermal fluids.

Our offer spans from low to high temperature drilling mud chemicals, to drill through low, medium and high enthalpy reservoirs and for both shallow and deep geothermal systems.  Among other products we offer biodegradable viscosifiers, fluid loss reducers, bio-based surfactants and “all-in-one bag” multi-functional products which comply with the strictest environmental classifications in the world.

When you need to build an Enhanced Geothermal System (EGS) or an Advanced Geothermal System (AGS) you can rely on Lamberti for the supply of the chemicals you need for hydrofracturing, acidizing and cementing operations in different types of rocks.

We can offer chemicals to design the right solutions for scaling, corrosion control and scavenging issues, to maintain a Geothermal District Heating as well as a flash, binary or ORC Geothermal Power Plant.

Additives for Geothermal

The multiplicity of technologies available in our company enables us to offer the full range of specialty chemicals for drilling fluids, reservoir hydrofracking, rock acidizing, well cementing and geothermal fluids transport and handling.


Available for application as torque reducers, drilling ROP enhancers, metal/metal and metal/rock friction reducers and extreme pressure lubricants. FRONLUBE are our environmentally friendly, high performance lubricants that cover a wide range of temperature and dispersibility/solubility requirements.

Shale Inhibitors and Encapsulators

Our Portfolio of shale inhibitors allows effective inhibition and control of hydration and dispersion. Thanks to the low dosage required versus traditional KCl/glycol systems, our HYBSTAR product range offers economical and logistical advantages.

Thinners and Dispersants

LAMSPERSE are synthetic low molecular weight acrylic derivatives suitable for a variety of temperature conditions and diverse types of drilling fluids systems. Our portfolio includes zirconium based products for HT applications.

Drilling Detergents and Surfactants

ALBISOL and DRILTAL improve water wetting action on all solids, thereby reducing the sticking tendency of reactive shale cuttings, wall packing and bit balling.


DEFOMEX are a full range of liquid products based on silicone, fatty alcohols or alkylene oxides derivatives designed to break down the foam in the drilling fluid.

Viscosifiers and Fluid Loss Reducers

We manufacture CARBOCEL, CEPAC and LAMPAC complying with international standards (i.e. API/ISO).
HYSOPOL are engineered polymeric fluid loss reducers designed to work in specific temperature conditions.

Gelling Agents

We manufacture a complete range of POLYFLOS gelling agents, such as High Viscosity Fast-Hydrating Guar and Low-Residue Guar Derivatives like HPG and CMHPG. They can be supplied as powders, slurriable powders and slurries.


Instant or delayed borate-based to produce strong gels also available as HYFRAC.

Borehole Stabilizers

BORESTAB products family reduces the risk of caving when unstable formations are encountered during drilling.

Corrosion Inhibitors

INICOR inhibits corrosion of downhole and surface equipments, they are based on surface-active organic chemicals and protect from attack in corrosive environments such as salt water, acid gases, steam and presence of oxygen.

Pipe Freeing Agents

Designed for easy and fast preparation of spotting fluids, PRESANTIL dehydrates the wall cake and lubricates the surface between the pipe and the wellbore.


CARBOSAN products are suitable for the control of yeasts, fungi, molds, aerobic and anaerobic bacteria (including sulfate-reducing bacteria).


LAMOX products include organic based H2S scavengers and oxygen removers.

Scale Inhibitors

Specifically designed to control barium, magnesium and calcium scale in completion fluids, pipelines and geothermal plants.

Acid Corrosion Inhibitors

Acid corrosion inhibitor is the most critical component of an acid-based stimulation fluid for carbonate reservoir; our expertise in this application will provide the most appropriate AI product for several technical issues, from low to very high temperature, from 15% HCl to 28% HCl and from organic acids to mud acids. Environmentally friendly compositions are available for regulated areas.

Cement Additives

Include spacers, retarders, liquid and powder dispersants, defoamers & antifoams and fluid loss reducers.
