    • ACD-GEL|Gelling Agent

      Introduction:

      SL-ACD-GEL is an organic copolymer used in the oil and gas wells acidification operations to produce stable gel in order to retard the acid fluid flow through with lower fluid loss.

      SL-ACD-GEL is a gelling agent for HCl acid solutions. Viscosities of 50 to 60 centipoise can be obtained in 15% HCl up to temperatures of 250ºF. SL-ACD-GEL is applicable in all strengths of regular HCl; however, the viscosity of gels in higher strength acid solutions ...

    • Friction Reducer

      Ultra-low Molecular Slick Water System

      1. Background Introduction

      As for the unconventional oil and gas reservoirs with low permeability, high strength rock, low closure stress and natural fracture formation, slippery water fracturing fluid system has better network crack performance than guar gum system and the formation damage is low, which greatly improves the yield of fracturing fluid. Conventional drag reducing agent is not able to ...

    • High Temperature Gel Stabilizer for Fracturing Fluids

      Product Description

      Linear gel may dehydrate due to exposure to high-temperature, causing a loss of viscosity and risk of screen-out – cessation of pumping due to loss of fracture width which causes a spike in the treating pressure. Screen-outs can be dangerous and operationally challenging and time consuming to remediate.  Stabilizers are therefore required at temperatures greater than 200°F, or approximately 95°C. Special compounds have been develo...

    • Non-Emulsifier

      Water-based fracturing fluids can form emulsions with the residual oil in the formation during or after fracturing or during other stimulation treatments. Such an emulsion can block the fractures and cause formation damage. The main function of a non-emulsification agent is to break such an emulsion in-situ before the stimulated well is p...

    • Corrosion Inhibitor

      Acidification is one of the most effective technical measures for oil-gas well and water injection well stimulation during the carbonate reservoir development process. However, acid constituted a serious corrosion to the well in the production until 30's in twentieth century that the first batch of corrosion inhibitor was presente...

      Introduction

      Mechanisms of Clay Dispersion

      In migration, clay minerals can be dispersed by contact with a foreign fluid, or they can be entrained by produced fluids and transported until a restriction (normally a pore throat) is encountered where the entrained particles bridge, forming a restriction to the capillary. The mechanism of clays and other fine minerals has been extensively explored in other sources.

      Clay minerals are composed of small crystal structu...
