using a drill string. The drilling string usually includes a series of "pexfoxacxon" or "bottom and well" (DHA) pipe. The BHA includes at least one drill bit and may include additional components that will rotate the drill bit

Uientss u meuic on while increasing (MWD) / registration while drilling (L D) and another 5 specialized equipment that would allow directional drilling. In conventional drilling, the casings are typically installed in the borehole to prevent the borehole from collapsing or preventing fluid and pressure from invading the borehole. The first installed tubing is known as surface tubing. This surface tubing is followed by one or more intermediate tubings and finally by production tubing. The diameter of each successive tubing installed in the borehole is less than the diameter of the previous tubing installed in the borehole. The drill string is lowered into the borehole to drill a new section of the borehole and then moves out of the borehole to allow the borehole to be installed in the borehole. As discussed in further detail below, the record can be conducted in the borehole while the new section is being drilled or after the new section is drilled or while the tubing is being run to the new section. -Texadicularly, open drilling training evaluation records have been obtained using wireline record. In the wireline record, the formation properties are measured after a section of a borehole is drilled, but before a tubing runs to that section of the well. The operation involves lowering a logging tool at full concentration of the sounding well using a wire line (shielded electric cable) wound on a crank drum and then pulling the sound logging tool from the sounding well. The registration tool measures the formation properties and pulls out of the borehole. As a waste in hostile environments, the logging tool can also measure training properties as it is lowered into the borehole. The wire line transmits the acquired data to the surface. The length of the wire line in the borehole provides a direct measure of the depth of the logging tool in the borehole. The wireline register can provide high quality, high density data quickly and efficiently, but there are situations where wire line registration can be difficult or impossible to run. For example, in highly deviated or horizontal boreholes, gravity is often insufficient to allow lowering the hexagonal depth at full depth or simply unwinding the wire line from the crank drum. In this case, it is necessary to push the logging tool along the well using, for example, a drill pipe, spiral pipe or the like. This process is difficult, time consuming and expensive. Another situation where wire line registration can be difficult and risky is in a borehole with stability problems. In this case, it is usually desirable to run the tubing immediately to protect the open piercing. LWD is a newer technique than wire line registration. It is used to measure formation properties during the boreholes of a section of a borehole, or shortly thereafter. An LWD tool includes recording devices installed in drill collars. The drill collars are integrated into the BHA of the drill string. During drilling using the drill string, the recording devices make the formation measurements. The LWD tool records the data acquired in its memory. The recorded data is removed when the perforation stops and the perforation saxta coxxe to the surface. During drilling, a subset of the acquired data can be sent to the surface using conventional telemetry systems. LWD data transmitted to the surface in real time can help make quick and accurate decisions regarding drilling and hazard identification. The scale of available LWD services and registration speed are limited compared to the wireline record. In LWD, the recording speed can be limited by the real-time data regime of the telemetry of the MWD tool. In this case, the drilling regime can be slowed down so that enough data can be sent up the well for evaluation or training decisions. However, LWD has an advantage over wire line registration in that the properties of the formation are measured-before the drilling mud invades the formation deeply. In addition, LWD can be used in boreholes that may prove difficult or even impossible to measure with conventional wireline registration. For example, because the LWD tool is part of the analysis tool, xegistxax can easily deviate well and horizontally drilled wells, while the wireline record may require thrust from the logging tools using drilling tubing, spiral pipe, or the like. The complete drilling record (TBL) is a much newer technique than LWD. Allows open drill formation evaluation records to be obtained without moving the drill string out of the borehole. (See, for example, John Runi et al., "Through Boxe Drilling Systems: a New Drilling Gption", SPE 79794, February 2003), A typical TBL system includes a drill string having a drill bit with a drill insert. Removable and re-detachable and a latch fixed to the drill insert. During drilling, the latch is held in the drill stem. The TBL system also includes a saxta of logging tools (eg, gamma, resistivity, density, neutron and sonic recording tools) and may include a MWD tool for pexmitíx real-time data transmission. When the drill bit reaches full drilling, the drill string is pulled back and the drilling tool string is run in a smoothing line or pumped down the drill string bore. A special movement tool attached to the bottom of the registration tools releases the drill bit latch, allowing the bit insert to be released from the drill bit, allowing the hex bits to pass through the drill bit. When the logging tools under the drill bit, registration occurs as the drill string pulls back from the drill hole. After registering the open hole, the registration tools are pulled through the drill bit with a straightening line. The latch attaches itself to the drill stem and frees the special movement tool at the bottom of the registration tools, allowing the hexagonal tools to move from the drill string and continue drilling. U.S. Patent No. 6,119,777 (Runia) discloses a conventional method of drilling wells conventionally drilled while running a well into the borehole. The nfexiox end portion of the entrubado runs to the borehole, termed as the tubing shoe path, is provided with a registration tool. The recording tool is releasably retained in a fiberglass-reinforced epoxy tube (FRE) fixed to the inner surface of the tubing shoe path. In one example, the xegistxo tool is composed of a gamma-ray recording device, a neutron-recording device, a density recording device, and an echo / memoxie caxiucho. The density measurements are made through a window in the formed shoe tread track of FRE. Some sections of the pipe-zapa track are made from vidxio paxa FRE to optimize the record response of tools affected by the steel. In general, the accommodation shoe track is made of pexfoxables annex materials that can be punched out if necessary. The tubing shoe track also allows for mud pumping. The recording is conducted as the tubing runs into the borehole. After the tubing is installed and before cementing the tubing in place, a clamping device is connected to the tubing. registration tool. The clamping device is also connected to a spiral wire or pipe line provided with electrical conduction means, thereby allowing the acquired data to be transferred from the recording tool to the surface. After transferring the data, the registration tool is removed, and the tubing is then cemented in place- There remains a need for techniques to obtain open drilling training evaluation records, particularly when LWD would not be effective in cost and registration Wireline may be difficult and / or risky-Compendium of the Invention In one aspect, the invention relates to a system for determining a surface parameter thereof, the system comprises a housing adapted for subsurface arrangement, a registration tool comprising one or more registration devices, and a holding device that couples the registration tool to the housing so that the registration tool hangs below the tubing when the tubing is disposed in the sounding well.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1A illustrates a recording system in accordance with one embodiment of the invention. FIG. IB shows a pad in a recording tool driven against a formation in accordance with an embodiment of the invention. Figures 2A-2D illustrate a method for recording while confounding with a mode of the invention. Detailed Description of the Invention The invention will now be described in detail with reference to new preferred embodiments, as illustrated in the accompanying drawings. In the following description, a number of specific details are set forth in order to provide a complete understanding of the invention. However, it will be evident to an expert in the field that the invention can be rendered without some or all of these specific details. In other cases, well-known particularities and / or process steps have not been described in detail in order not to obscure the invention irmecesaxiamente. The paxticulaxi ades and advantages of the invention can be better understood with reference to the drawings and discussions that follow. The embodiments of the invention provide a method and system for obtaining open drilling training evaluation records. The system includes a recording tool, a tubing (or coating), and a latching device. The latching device is attached to the registration tool and used to hold the registration tool to the casing so that the registration tool hangs below the casing. The logging tool is dimensioned so that it is xetixable through the perforation of the casing. The method includes running the casing into a borehole. The registration tool can be attached to the tubing before the tubing is coxed to the borehole or when the tubing reaches the beginning of the open bore. With the registration tool hanging under the tubing, the tubing is co-located at the desired height while the logging tool registers the drilled hole. The logging tool is removed through the tubing bore- Figure 1A shows a system 100 of record that is running towards a perforation 102 open, that is, an untubed portion of a borehole 104 traversing a formation 106, in accordance with one embodiment of the invention. In this example, a tubing
103 has already been installed from a portion of the borehole 104, and the open bore 102 is below the borehole 103. It should be apparent that the drawing is not to scale. The record system 100 is shown as the largest increment relative to the borehole 104. of sounding and tubing 103 installed to clearly illustrate the principles of the invention - Well bore 104 is drilled in a conventional manner, i.e. using a drill string (not shown) - For a low cost borehole, is it preferable not to use LWD while drilling the open-loop period? even when the mud xegistxo or gamma ray record MWD can be made while drilling. The record system 100 can be coxxex to the perforation 102 opened immediately after moving the drill string out of the borehole 104. The borehole 104 may be vertical, as shown, or may be dixeccional. The registration system 100 includes a registration tool 108. The tool 108 of
-registxo includes registration devices 108b, 108c, 108d, and 108e. It should be noted that the registration tool 108 can include any number and combination of recording devices. Each recording device includes appropriate sensors and electronics to make measurements and record measurements. For example, the recording tool 108 may include xegistxo devices selected from the gxupo consisting of acoustic tool, seismic sources / sensors, electromagnetic propagation / induction tool, neutron tool, density tool, neutron density tool, gamma ray , nuclear magnetic resonance (NMR) tool, forming pressure tool, image forming tool, deptometer, ultrasonic gauge tool, gravity sensors and combinations thereof. These tools are known in the art- However, certain modifications can be made to the tools to take full advantage of the invention. Some of these modifications will be discussed later. The registration tool 108 may further include a MWD telemetry tool 108a, which provides real-time data transmission through selected registration intervals. The registration system 100 further includes a holding device 110 housed at an upper end of the registration tool 108. The registration system 100 further includes a casing 112 equipped with an axial / torsional clamp 118. The axial / torsion clamp 118 includes a profile that engages a locking surface in the clamping device 110, thereby holding the tool 108. registration to tubing 112. From -preference, clamping device 110 is releasable from axial / torsional interlock 118. An example of an appropriate axial / torsional anchorage is available from Tesco Corporation under the trade name CASING PROFILE NIPPLE (CPN) . An example of a suitable clamping device is also available from Tesco Corporation under the tradename DRILL LOCK ASSEMBLY (DLA), When the clamping device 110 engages the axial / torsional lock 118, the registration tool 108 hangs below the casing 112. In its clamped position, the clamping device 110 receives torque and weight from the casing 112. The clamping device 110 includes a commanding head 110a.
(or fishing head), which would allow it to be withdrawn through the perforation of the tubing 112. In a specific example, the hexxa 108 of register includes a sonic or acoustic tool 108b, a density tool 108c, a tool 108d of Gamma rays, and an electromagnetic xesist ± vi ad hexxamienta iG8e (v.gr ,, propagation), The density tool 108c includes a pad 109 through which it perceives the formation 106. The pad 109 may be movable between a position xetxaxda and a deployed position, or it can be fixed in position. The recording tool 108c may not be able to accurately determine the density of the focus 106 through the pad 109 if the distance, i.e., the space between the pad 109 and the array 106 is greater than about 1.27. cm (0-5 inches) during density measurements. Therefore, a method for maintaining a small distance between pad 109 and formation 106 is desirable. Referring to Figure 1A, if the pad 109 is fixed to 108c density tool, and if the well 104 polling is not strictly vertical, then the hexxamíenta 108c record can be oriented so that the pad 109 is facing aJo jo. The gravity will then force the pad 109 against one side of the borehole 104. Alternatively, the tubing 112 can slowly rotate as it descends to a well of non-vertical drilling, and density praede edix duxante time when the pad 109 faces downward, can be used magnetometers and aceierómetros the tool IOS of xegistxo paxa detexminax the oxidation of the pad 109. In one embodiment, the registration tool 108 is equipped with a mechanism for diverting the pad 109 against the borehole 104. As illustrated in Figure 2C, the mechanism includes an auxiliary 111 near the density tool 108c. The auxiliary 111 has an extendable shoulder Illa that is diametrically opposed to the pad 109. Typically, the extension arm Illa remains retracted until the registration tool 108 reaches the opening position 102 abiexta. When the registration tool 108 reaches the open bore 102, the extendable arm Illa is released and urged against one side of the borehole 104. This forces the pad 109 against formation 106- Any appropriate mechanism, v, g, f spring, can be used to drive the extendible bxazo Illa against the well probe 104, In the extended position, the extensible arm Illa can also provide caliber measurements as the hexxmeter 108 of xegistxo atxavíesa perforation 102 open. When the extendable arm Illa is deployed, the portion of the registration tool 108 between the density tool iG8c and the casing 112 can be allowed to deflect as shown in the drawing. Alternatively, an articulation joint, such as provided pox auxiliary 107 SPAT adox (Figure 2C) and connections 107a pivot 107b (Figure 2C), can be placed properly in the tool 108 of record so that the pad 109 deflect against the formation 106 without diverting the portion of the log 108 hexxamienta 108c between the density tool and the tubing 112. Turning to Figuxa 1A, the open pexfoxación 102 has drilled to a desired depth using a drill string (not illustrated). Pexfoxation 102 abiexta can be pexfoxed vertically or directionally. The drill string may have included a BHA (not shown) that has a steerable engine and an MWD tool. The MWD tool (not shown) may have been used for evaluation of low level formation, v.gr, mud log or gamma log,
• While drilling- Paxa xeducix to the minimum costs, the BHA preferably did not include LWD tools, The drill string can be moved out of the wellbore 104. In one example, it has been known that the probe well 104 is not stable enough to be left open for the extended periods necessary for wire line registration or that it is more cost effective to run a casing immediately to save installation time. Using the registration system 100 of the present invention, the registration can be conducted while the tubing 112 is moved toward the open piercing 102. Figures 2A-2D illustrate a procedure for recording while the open piercing 102 is intubated. On the surface, the clamping device 110 is fixed to the upper part of the recording tool 108 (Figure 2A). The axial / torsional lock 118 is also fixed to the lower end of the housing 112 (FIG. 2A). Then the clamping device 110 and the registration tool 108 are run towards the casing 112 until the clamping device 110 engages the axial / torsional interlock 118, leaving the registration tool 108 hanging below the casing 112 (Figure 2B) . Next, the tubing 112 is run into the borehole 104 with the registration tool 108 hanging below (Figure 2C). The registration tool 108 starts to xegister when it reaches open pexfoxation 102. The tubing 112 is run until the recording tool 108 reaches the total depth, namely, the bottom of the wellbore 104. At this point, the clamping device 110 is released from the axial / torsional interlock 118, for example, using pressure pulses, and a withdrawal tool 120 is run into the casing 112 to remove the clamping device 110 and the tool 108. of registration a. through casing 112 (Figure 2D). A. Next, a cement flotation retainer (not shown) is pumped down from the casing 112 until it engages the axial / torsional clamp 118. With the cement flotation retainer in place, the casing 112 is then cemented in place. Place in a conventional manner - In an alternative procedure, instead of coupling the registration tool 108 to the casing 112 on the surface, the casing 112, equipped with axial or torsional / 118, runs into the borehole 104 without the registration tool 108 hanging below, when the axial / torsion beam 118 is at the salix premium towards the open bore 102, the run of the casing 112 is stopped. Then the holding device 110 and the registration tool 108 down to tubing 112 at the end d? a wire line cable or straightening line or spiral pipe. The clamping device 110 is made coincident with the axial / torsion beam 118 at the lower end of the casing 112, so that the recording tool 108 then hangs below the casing 112. Then, the coxxid of the casing 112 and recording using the Record tool 108 continues as shown in Figure 2C. The recording speed is the same as the casing input speed and can be adjusted based on the type of measurements to be made. For example, sonic and resistivity measurements can be made at high recording speeds. Therefore, the recording speed when measurements are made using sonic and resistivity tools can be high. On the other hand, the optimal velocity for density measurements using typical LWD density tool is approximately 1.6t9 cm / s (200 feet / hour) or less. In this case, the registration speed can be slowed through d? interesting areas where density measurements would be taken. These interesting areas can already be identified by the gamma ray or muddy xegisthox when piercing the open bore 102. The recording devices included in the registration tool 108 can be existing registration devices used in L? D tools or they can be log devices built on purpose. For exampleIt is not uncomplicated that the recording devices included in the registration tool 108 have mud flow passages. In addition, the recording devices included in hexagonal socket 108 can be disengaged so that registration tool 108 can be adjusted through the smaller tubing that would move into well bore 104. A logging tool having a total diameter of about 7.62 cm (3 inches) would be possible to fit inside the casing strings. This form, the same registration tool 108 can be used for all registration services in the polling well 10. Preferably registration tool 108 includes batteries and register memory similar to the LWD hexes. The registration tool 108 could have a main power cartridge and register memory or each recording device included in the hex tool could be equipped with power and register memory. The registration tool 108 does not have to be as strong as a LWD hexxairdepta since it does not mean that iomax drill bit drilling and bit torque measurements, the record tool 108 could be made light weight so that can you remove using a line cable d? conventional wire. The data stored in the record tool 108 can be transmitted to the surface using the wire line cable before the recording tool is removed to the surface. The invention typically provides the following advantages. The xegxstxo hexxamienta can be moved under a tubing to monitor an open drilling section of a borehole. The risk and cost of xegistx in an unstable downhole environment are reduced since open drilling is accommodated as it is recorded. Also, the quality of data collected is high because the recording devices are not enclosed in the cased The clamping device can be made less strong than, for example, the Tesco DLA, since the xegistxo system does not look to perforate. The registration tool can be made light weight so that it can be removed using conventional wire line cable and pulley instead of a split crown on the equipment as required for the Tesco DLA, this means that the registration system of the invention can be used in any equipment. The recording speed can be very high and can also be made as needed when certain measurements are made, such as density measurements. The registration tool can. Include conventional and specialized registration tools. While the invention has been discredited with respect to a limited number of embodiments, those skilled in the art, who have the benefit of this disclosure, apologize that other embodiments may be designed that do not leave the scope of the invention described herein. For example, while tubing / cOtrvet? Cles coatings are formed of metal, embodiments of the invention can be implemented using non-metal tubing / coatings (e.g., composites).
