Oil Well Drilling
Bisley have a range of innovative products for drilling, extraction & cementing of wells.
Bisley’s portfolio in this field comprises products for oil well establishment as well as chemicals for continuous and cost-efficient production of valuable oil and gas resources.
Bisley offers dispersants / water reducers, cements, fillers, flocculants, corrosion inhibitors, de-foamers, and scale inhibitors.
Products such as Lignosulfonate, Poly Naphthalene Sulfonate, Melamine Formaldehyde Condensate and Polycarboxylates can be used as dispersants / water reducers.
Following successful drilling, the steel casing is anchored firmly in the ground with special cement. More and more frequently the cement mixture has to be pumped over long distances. Bisley’s state-of-the-art dispersants improve the flow characteristics of the cement slurry with low water content, so it can be pumped without setting too soon.
CAC & CSA Cements are used for wellbore cementing, to increase the speed of the set time and the density of the concrete by introducing an Ettringite based system. This makes the cementitious matrix less permeable and increases its strength, while also imparting higher thermal resistance.
Silica Fume is an efficient pozzolan that yields higher strengths, improved pumpability and reduced permeability.
Microspheres allow for density reduction whilst maintaining acceptable strength.
Accelerators such as Lithium compounds for Alumina based systems and Calcium Nitrate for Portland cements are available.
Our retarder range includes Sodium Gluconate and Tartaric compounds.
