Definitions
- the present invention describes a drilled well exploration system and a method for extracting fluids from said drilled wells.
- the present invention is in the fields of petroleum engineering, and mechanical engineering.
- Oil prospecting has been the subject of long studies and major technological contributions in recent decades, despite the emergence of new sources of energy use, forecasts point to many decades ahead of the great importance of this type of natural resource.
- Intelligent completion of oil producing wells is a type of completion that allows the production of several production zones together, monitoring and controlling said production zones remotely and individually.
- the use of intelligent completion enables exploration of marginal reserves and acceleration of hydrocarbon production through joint and controlled reservoir production, significantly increasing the field recovery factor.
- the average life of the BCS is 2 years. That is, in this average time interval, a probe intervention should take place to replace the BCS that has stopped working. This intervention lasts an average of 45 days and, in addition to the high expenses with "daily drilling", it is necessary to internalize the time that the well ceased to produce (loss of profit), awaiting drilling for intervention. To minimize this, the well is usually equipped with BCS and gas lift chuck, which will start as soon as the pump stops working while the probe does not arrive. This time may be long and depends on the demand for probes in the period demanded.
- Document CN103382835 discloses a multiple producing zone completion system provided with packers separating said producing zones in order to provide segregation between said producing zones.
- Each producing zone has an intelligent control device, for example, the first producing zone is controlled by a first intelligent control device, the second producing zone is controlled by a second intelligent control device, and so on.
- the production column is associated with all producing zones, but only produces fluids from that zone that a control system decides to produce.
- the teachings of this invention are about an automated system of detecting which zone is producing fluids with the least amount of unwanted fluids mixed with the fluids of interest. This paper does not suggest how to reconcile the prospecting of fluids from well-completed wells with the use of high-tech intelligent mechanisms in order to reduce costs with the wells, especially those associated with submerged centrifugal pumping set exchange and probe interventions.
- US8127845 discloses a hydrocarbon producing multiple zone completion system based on the selective segregation of the zones that will produce fluids.
- a sliding sleeve the operator operating a service rod is able to isolate a misaligned production zone from the holes in the inner shell from the holes in the outer tube, whereas when it is desired to produce from another production zone, this one The operator aligns said holes so that fluids can rise through the production column.
- Said alignment and misalignment of holes is made with the service rod and its outer shoulder which, in contact with the inner shoulder present in the sliding sleeve, transmits the axial movement of the service rod in order to align or misalign the holes.
- This document reveals some facilities for completions, as it is possible to produce from several producing areas jointly or separately. For example, if in a given producing zone the pressure is much higher than a second producing zone, it is possible to produce from this higher pressure producing zone until the pressures are balanced and the formation of hydrocarbons occurs simultaneously. between the various producing zones. In addition, it is possible to drain unwanted fluids (water, mud, etc.) from a particular producing area, while the others are closed, avoiding possible contamination. This document does not reveal a way to shorten the intervention time of oil-producing wells, especially those with smart completions. Nor does this document disclose a means of removing the submerged centrifugal pump assembly into well-completed wells without the risk of complex and costly fisheries.
- US20140083684 discloses a hydrocarbon production well completion system that permeates through multiple formations.
- the system is based on packers that divide the multiple forming zones and, through a pressure sensor that analyzes the pressure in said forming zone sends the information collected through the cable. This information is used to control the flow that is formed from each of the production zones.
- Conventional completion equipment includes gravel, pressure sensor, filtration screen and, most importantly, a flow control valve driven by a hydraulic control. The flow control valve is able to fully close the forming zone or simply restrict part of the production flow according to momentary needs.
- the system of the present document also has a productive flow pumping device, safety valve and total isolation valve of the formation. This document does not disclose how to produce multiple forming zones reconciling the minimal need for probe intervention with the use of submerged centrifugal pumping equipment, which has a short service life.
- US 8,651,188 deals with a gas lift valve comprising longitudinal tubular structure provided with an inlet and outlet, a flow passage between the inlet and outlet, and a flow pipe disposed within the tubular structure.
- the disadvantage of this document is that it does not provide a solution for the passage of fluids of different densities, and that it does not provide a means for increasing gas flow.
- US8662184 discloses a capsule system for coating a set of two submerged pumps that can operate simultaneously or in backup system. This document emphasizes the importance of using two pumps in a completion due to the difficulties associated with the exchange of said pumps. While suggesting that the capsule assembly should be withdrawn from the well casing for maintenance, the inventor has not provided facilities for withdrawing the pump assembly from said casing, so time consuming work is required for such operation.

This very important aspect prevents such objects from falling above the 'bass packer!' This would result in the need for a special, complex and risky "fishing" operation that could lead to the loss of the well.
- the option to continue producing the well using gas lift can be used with gas injected by the ring entering the gas lift chuck host to reach the chuck. gas lift.
- the gas lift chuck host can direct flow into the chuck or into the column, depending on the flow of pumped fluids. That is, the system of the present invention is selective with respect to pumped flow rates and fluid types: whether gas or liquid. This is critical for preserving the high-speed gas lift valves generated by pumped fluids into the annular space during damping.

- the extraction capsule comprises: internally polished tube, casing tube, selective gas and fluid inlet gas lift chuck host, formation isolation valve, check valve, and a sealing anchor with elastomeric elements.
- the submerged electric pump assembly comprises: electric cable, pump, electric motor, pipes, and telescopic joint.
- the steps of the method occur independently of each other.
- This entire submerged electric pump assembly is contained within the watertight casing, isolating the fluids produced from the formation of the rest of the well, called the annular space (space formed between the production casing and the production column + casing). BCS).
- the non-solid capsule remains in the well thus enabling any object that falls into the well to be easily recovered (as they will be inside the capsule). This very important aspect prevents such objects from falling above the "packer de gravei” which would result in the need for a special, complex and risky "fishing" operation that could lead to the loss of the well.
- the option to continue producing the well using gas lift can be used with the gas injected by the annuler entering the gas lift chuck host to reach the chuck. gas lift.
- the gas lift chuck host can direct flow into the chuck or into the column depending on the flow rate of pumped fluids. That is, the system of the present invention is selective with respect to pumped flow rates and fluid types: whether gas or liquid. This is critical for preserving the high-speed gas lift valves generated by pumped fluids into the annular space during damping.
- Advantages presented by the present invention include: fast assembly and lowering of the capsules; quick assembly of pump sets; possibility of exchanging pumps without removing capsules; possibility of eliminating swing and dummy run maneuvers; significantly eliminating or minimizing the possibility that in-well "fish” generate complex and risky "fisheries” with large financial losses and even well loss; possibility of adding recoverable Gas Lift Chuck (MGL) with BCS sets; possibility to perform TFR with BCS and superior completion just by changing the pumps used in each operation without removing the capsule.
