Salt-Water Disposal

Overview

In oil and gas, Salt-Water Disposal (SWD) wells play a critical role in the proper disposal of produced water to comply with existing regulations. In today’s market, rising demand for SWD is placing additional risk and cost on operators. SWD tagged water is increasing in volume with lower reuse options, and the quality of produced water is deteriorating due to reductions in chemical spend at the central oil and gas processing facilities. Produced water arriving at SWD wells for processing can contain higher amounts of total dissolved solids and total suspended solids which drive up costs, limit allowable injection pressures, and increase the risks of injector failure.

Customer Challenges and Pain Points

SWD well operators typically face the following challenges in their operations:

  • Mechanical integrity due to erosion and corrosion
  • Reduced permeability and porosity due to solids loading
  • Scale blockage from multivalent precipitation
  • Transportation to move water offsite due to high differential pressure (Dp) at the
    injector 
  • High chemical treatment costs

Solugen Solution

Solugen approaches SWD operations with a platform that couples industry best practices with proprietary methods and prescriptive solutions tailored to maximize efficiencies and reduce costs in this competitive operation. The value of this program is realized through quantified operational cost reductions, maximized water injection rates, and assured operational uptime.

BioPeroxide™ is Solugen’s bio-based hydrogen peroxide product line that provides general oxidation clarification for produced water in SWD applications.

ScaleSol™ is Solugen’s flagship scale control product line that is an environmentally acceptable replacement for phosphonates. It targets calcium, magnesium, and iron-induced scale buildup and formation in SWD wells.

ScavSol™ is a multivalent sequestrant to inhibit precipitating metal salts in SWD operations. It is unique in that it does not contain sulfates which can contribute to microbiological growth, corrosion, and hydrogen sulfide evolution.

CorrSol™ is designed to prevent under-deposit corrosion, fouling, and maintain clean operating surfaces to reduce corrosion in tubulars and flowlines in high and low brine fluids.
