AntiScalant DosTreat™ Solution


Ensure Optimize And Continuous Production

AntiScalant DosTreat Solution
___________

Optimize Oil & Gas Production Subsequently
Manage The Scale Formation Potential

AntiScalant DosTreat™ Solution provide an effective production optimization oil & gas industry, in addition to ensure anticipating, limiting, or preventing undesirable formation during production and transportation of crude oil by flow assurance plans. Because different mineral and salt types from its origin make most of the reservoir formation; consequently oil and gas, and scale-resulting minerals are naturally formed together in the same environment and certainly can never be isolated.

In most cases salts and formation water which dissolving components are associate at reservoir conditions but under specific production conditions for instance substantial change in flowing pressure and temperature meanwhile, the formation of scales can occur before the production stream reaches the surface. Since manipulating of downhole flowing conditions are not easily , changing production conditions favor the nucleation of scales along perforations, valves, production tubing, casing, pumps and other down hole completion equipment, with detrimental effects on production.

Scale Management:

Identification of the optimum approach to minimizing their negative effects is the primary goal for production optimization and our scale management strategies are based on scale formation and location prediction, moreover evaluation of potential chemistry, and deployment techniques for long-term effectiveness; in the same vein DOSAS can work with you to address your oilfield scaling challenges and the level of support we provide is customized to meet your individual requirements by

 

DosTreat™ Series Solutions

The inhibition mechanism by which a scale inhibitor functions depends on its chemical nature, whether a chelating agent or threshold (liquid or solid inihibitor) scale inhibitor in other hand it can function by one or more mechanisms as described below.
_____________________

A chemical scale inhibitor can also function as a surface conditioner to preventing scaling in this way, the tubing walls or equipment surfaces are conditioned in such a way that the adherence of crystals onto the walls or surfaces is prevented.

 

DosTreat™ Scale Inhibitor

Threshold scale inhibitors prevent scale precipitation during delaying or preventing the mineral crystal nucleation and/or crystal growth.

DosTreat™ Solid Scale Inhibitor

Solid product that slowly desorbs to provide immediate and long-term protection against scale deposition meanwhile minimizing risks of lost production in hydraulic fracturing.

Product Name Description

ChelaTreat™ Scale Remover

The negative ions of the scale inhibitor molecules attract the metal cations in the solution, therefore the cation is prevented from reacting with scaling anions in the solution, as a result the scaling process is prevented.

Simulation & Evaluation, Optimize Production

Our laboratories and technicians have the expertise and tools to perform all the tests required to manage the treatment and measure the performance for instance:

  • Static prescreening for compatibility, efficiency, and adsorption
  • Dynamic tube blocking test for determining the injection dosage or minimum inhibitor concentration
