"Hardness reducers in drilling" published on by De ://?language=en. Rock Hardness Reducers. Overview; RTP. The additive for drilling muds RTP is purposed for using in water based drilling muds for reducing rock hardness by means of decreasing interfacial tension at the «liquid — formation» boundary.

Reagent is to be used for increasing penetration rate during drilling hard formations resistant to sloughing   In drilling fluid testing, alkalinity can be measured on either whole mud (designated with a subscript "df") or on the filtrate (designated with a subscript "f"), as collected with a filter press.

The data collected from the alkalinity test can also be used to estimate the concentrations of hydroxyl (OH -), carbonate (CO 3 -2) and bicarbonate Effect of Hardness Reducers on Failure Characteristics of Rock The chemical additives investigated have no influence on microbit drilling rate when drilling with zero differential pressure.

A Russian book by Rehbinder published in generated much interest in the possibility of aiding and accelerating the destruction of solids by the Calcium Reducer Brand: Doheny's.
