High-pressure Pumping Service

In the last five years, CPVEN executed more than 4,000 jobs in cementing, gravel packing, hydraulic fracturing, pumping acid and nitrogen.

In the year 2005, it carried out a successful cementing of the Travis Well 2X, at a depth of 22,500 feet, the deepest well drilled by 2014 in Venezuela. CPVEN has a participation in the market that oscillates, depending on the type of service and operational regions, between 15% and 35%.

Cementing

For the design of the cementing jobs, CPVEN has an original simulation software that allows the engineer to introduce different design alternatives and analysis in real time and post-operational evaluations. Furthermore, the program is compatible with the equipment for data input of production, pressure and density used during the operations, all in real time. The high-pressure pumping equipment and mixers have been designed and some built, by the company itself, in order to suit them best to the geological demands of the exploratory and producing areas in the countries where it operates.

CPVEN has its own technology and proven expertise in wells with critical characteristics such as: high pressure, high temperatures, gas sands, low gradient formations, aquifers close to the producing sands, highly inclined wells, and horizontal sections.

Operational results have been rated as ‘excellent’ by clients, as can been seen in the CBL records, in the different areas of the countries where CPVEN offers cementing services.

Gravel pack

Sand-control services are required in non-consolidated formations for the purpose of reducing the entry of particles, and thus obtain an optimal production throughout the life of the well.

CPVEN makes gaskets with gravel for sand control in an open well and tubing at low or high-density concentration of gravel per volume of transportation fluid. In addition, it has extensive experience in the use of SOS (‘Sand Oil Squeeze’) techniques and the equivalent with water SWS (‘Sand Water Squeeze’).

CPVEN carries out analysis of the formation sand in order to determine the type of gravel to be used in the packaging and the fluid most suited to the conditions of the well; furthermore, it offers services of gravel supply, grates and gaskets for pumping the material until the completion of the well.

Stimulation Matricial

CPVEN has wide experience in matrix stimulation. Among the treatments used, the following stand out:

  • Solvent-based, non-acid, stimulations.
  • Water control based on polymers.
  • Acid stimulations of carbonates using hydrochloric acid.
  • Acid stimulations of sandstones using acid mud.
  • Delayed-action acid emulsions for high-temperature wells.
  • Acid stimulations for controlling migration of particles.

CPVEN offers an innovative stimulation program, whereby the treatment is designed according to the mineralogy of the rock and of the physical properties of permeability and porosity. This program permits observing the behavior of the treatment in real time, making it possible to adjust the pumping production and increase the efficiency of the stimulation.

Nitrogen

CPVEN has nitrogen pumping units and portable nitrogen storage tanks that can be used for such services as:

  • Thermal isolation in steam-injecting wells.
  • Energized displacement of the stimulation treatments.
  • Well cleaning.
  • Skimming cementing.
  • Drilling under balance.

Hydraulic fracture

This is a stimulation service that seeks to increase the oil or gas production in areas of low permeability. The procedure consists in placing within the formation, pumping above the pressure of the fracture of the site, a special transportation fluid with sand of specific characteristics, with the purpose of creating more permeability in the vicinity of the wellhead, that allows to increase the conductivity of the formation, hence boosting the production flow.

Advantages:

  • Increases production
  • Develops additional reserves.
  • Exceeds very damaged areas.
  • Reduces the deposition of asphalt.
  • Increases the effective drainage area.
  • Reduces the number of wells necessary to drain an area.
  • Delays water conification.
