  • the main problems are: Maintain the stability of the well walls, since the formations are highly collapsible due to the presence of high percentages of battered sands. For this phenomenon, a fluid with clay inhibition is required, due to the presence of the latter's hydration, which causes swelling, dispersion, embolisms, colloidal solids, torque and drag problems, to mention.
  • the diameters of the augers used in these stages normally 26.0 "in diameter, it is necessary that the designed fluid has a good cleaning in the well, according to the operating conditions and advances.
  • the fluid must suspend drilling cuts and solids that the fluid contains in a homogeneous manner during the stoppages of fluid circulation, which are required by failures or adjustments in the drilling decisions.
  • the different rocks to be drilled have different physical and chemical characteristics, among those characteristics are porosity and permeability rocks and / or sands; who have greater permeability and porosity than shales or clay rocks.
  • the fluid invades these porous areas so that the fluid is required to generate a layer or coating that allows these permeable areas to be sealed, and with this control the problem of differential sticking that occurs in drilling operations is avoided.
  • the SP-KCL® fluid is designed with seawater, so it has in its composition enough inorganic salts that are a good means to propagate the electrical signals of the geophysical records, since these are used to take important information in drilling of wells. Secondary corrosion control is carried out with alkalizer, bitter gas controller and amine corrosion inhibitor, which is important to protect the pipes, equipment and tools used in drilling operations. When you have a good drilling fluid this is reflected in the activities of the other operations involved to drill a well, such as the cementing of casing pipes and the completion of the wells, the cements will act with better adhesion if the enjarres of Drilling fluids are thin and easy to remove.

  • the potassium chloride system uses the potassium chloride salt (KC1) as the main source of potassium ions for ionic inhibition. This system is effective because it uses polymers for the encapsulation of reactive colloidal solids. Polymers such as the filtrate reducer and the inhibitor of slippery clays and well stabilizer of hole walls are designed to be used for encapsulation. These polymers cover the cuttings and exposed shales, limiting the interaction with water.
  • KC1 concentration of KC1 required to inhibit these shales will vary. During drilling operations, shale cuts should be continuously monitored to determine inhibition. If the concentration of KC1 in the system is not sufficient, shale cuts will be soft and fluffy.
  • Potassium-based drilling fluids are used in areas where the chemical alteration of clays is required to be limited by interaction with drilling fluids. Potassium is used as an inhibitor ion due to the exchange of ionic bases of potassium ions with sodium and / or calcium ions between the clay layers and by fixing the potassium ion in the crystalline network of inflatable clay minerals. Another factor by which the potassium ion is used as an inhibitor is because it fits better in the crystalline networks of the clay due to its size, compared to the sodium ion and the calcium ion.
