These products are necessary for: Lot 1. Flexible Tubing. Flexible tubing is required to equip tubing systems and is used for nitrogen well unevenness, sand bridge washing, bottom motor milling operations and other special gas well operations. The two rollers that currently equip the installations have a high degree of wear, they have been used in deep wells with high pumping pressures. Lot 2. Spare parts for IC5, TW30, UW30, IP30, TW50 and TW80 equipment. It is used to replace defective or worn parts in IC5, TW30, UW30, IP30, TW50 and TW80 intervention systems, used in production, overhauls and special operations such as: cementing, milling, tubular material handling, plunging operations, attachments of packers and other bottom equipment to the wellhole, acidification, washing and drilling advancements to natural gas wells. Lot 3. Hydraulic deflection feather. Hydraulic deflection , cementable , is used in the borehole ( tubed or untubed ) when it is desired to drill diverted from a certain depth relative to a vertical borehole. Lot 4. Piston device. The necessity was identified within the sections of the SIRCOSS branch, according to the proposed objectives regarding the fulfillment of the capital repair programs and special interventions at wells. The plunger device is used in the unevening operations of the natural gas wells by plunger operation, cleaning the inside of the rod liner, by removing the drilling fluid and/or the residues of cement milk left inside it. They allow the gradual unevenness of the fluid column, which exerts a counterpressure on the productive layer, facilitating the gradual and controlled exit of the gases from the exploitation area. Lot 5. Sealing box for hydraulic head. As part of the interventions, repairs and production samples at natural gas wells that it performs, SIRCOSS Branch is endowed with various drilling/milling equipment and from the well mouth (hydraulic heads) that have in their composition the products described in this specification. The sealing box is a subassembly/spare part that is the main wear element of the hydraulic head. The cassette is mounted between the fixed and mobile part of the hydraulic head, with the purpose of preventing the penetration into the body of the drilling mud pumped to the bottom of the well. Operation under very severe regimes, with pressure shocks and the penetration of mud, sand and slightly acidic well gas particles that produce the pronounced wear and loss of tightness that these products must provide. In conclusion, there was a need to replace the products found to be defective. Lot 6. Vibrating sieve nets. The nets are used on the King Cobra Venom and Mud Data vibrating sieves, for separating and filtering the drilling fluid, which engages the detritus resulting from the dislocation by the drilling screed towards the surface. They separate the detritus from other mechanical particles in the drilling fluid allowing its reuse and recirculation without stopping the drilling operation. Any request for clarifications must be submitted in SEAP (http://sicap-prod.e-licitatie.ro/pub). The EC will respond clearly and completely to all requests for clarification/additional information on the 11th day before the deadline set for the submission of tenders. The number of days until which clarifications can be requested before the deadline for submission of tenders / applications will be 18 days. At the same time, according to the legal provision in force, any economic operator has the right to request clarifications on the content of the tender documentation and implicitly on the contractual clauses (which are part of the tender documentation) 18 days before the deadline for submission of tenders.
