---|
| 97 | <UL> |
---|
| 98 | <LI><P>First, petroleum geoscientists and |
---|
| 99 | engineers will seek understanding of the temperature data profiles |
---|
| 100 | which they use to monitor conditions in the reservoir and wellbore. |
---|
| 101 | In addition to the actual temperature data, the standard enables |

| 103 | record and process them, along with contextual data about the |

| 123 | refer to the Shell docment |

| 126 | E&P of this DTS Primer as part of the basis of the proposed |

| 127 | standard.</P> |
---|
| 128 | |
---|
| 129 | <P>The application of optic fiber thermometry in oil and gas is a |
---|
| 130 | young and rapidly evolving technology. For this reason, any |
---|
| 131 | standard may anticipate several iterations and evolutions in |
---|
| 132 | its early years, and should be designed with a degree of |
---|
| 133 | flexibility. The challenges of installing and operating a |
---|
| 134 | delicate sensor - the optic fiber - in a remote and hostile |
---|
| 135 | environment - the oil well - are still being mastered. The |
---|
| 136 | survey process still has a significant experimental aspect to it, in |
---|
| 137 | addition to the natural variability of the processes the technique is |
---|
| 138 | being used to monitor.</P> |

| 140 | <H3>Well and Wellbore</H3> |
---|
| 141 | |
---|
| 142 | <P>The WITSML definition of wellbore as "a unique, |
---|
| 143 | oriented path from the bottom of a drilled borehole to the surface |
---|
| 144 | of the Earth" is particularly suited to DTS in that |
---|
| 145 | at least one end of the sensing fiber in a wellbore will always |
---|
| 146 | extend to the surface to connect with the Instrument Box. A |
---|
| 147 | fiber will not be physically joined or spliced into fibers from other |
---|
| 148 | wellbores in a well. </P> |
---|
| 149 | |
---|
| 150 | <H3>Fiber Optic Technology and DTS Measurements</H3> |
---|
| 151 | |
---|
| 152 | <H4>Principles</H4> |
---|
| 153 | |
---|
| 154 | <P>When light is transmitted along an optic fiber, transmitted light |
---|
| 155 | collides with atoms in the lattice structure of the fiber and causes |
---|
| 156 | them to emit bursts of light at frequencies slightly different from |
---|
| 157 | the transmitted radiation which propagate back along the fibre and |
---|
| 158 | can be detected at its end. This is known as backscattering. |
---|
| 159 | Optic fiber thermometry depends upon the phenomenon that the |
---|
| 160 | frequency shifts occur to bands both less than and greater than the |
---|
| 161 | transmitted frequency. Furthermore, in the case of the Raman |
---|
| 162 | shifted bands the intensity of the lower frequency band is only |
---|
| 163 | weakly dependent on temperature, while the intensity of the higher |
---|
| 164 | frequency band is strongly dependent upon temperature. The |
---|
| 165 | ratio of these intensities is related to the temperature of the optic |
---|
| 166 | fiber at the site where the backscattering occurs: i.e., all along the |
---|
| 167 | fiber. The backscatter spectrum is illustrated in Figure 1. |
---|
| 168 | The intensities of backscatter of individual pulses is very weak, |
---|
| 169 | necessitating statistical stacking of thousands of backscattered |
---|
| 170 | light pulses.</P> |
---|
| 171 | |
---|
| 172 | <P><IMG SRC="dtsBackscatter.jpg" NAME="Graphic1" ALIGN=BOTTOM width=637 height=403 BORDER=0></P> |
---|
| 173 | |
---|
| 174 | <H4>Equipment: Instrument Box and Fiber</H4> |
---|
| 175 | |
---|
| 176 | <P>Several organisations manufacture and / or operate DTS equipment |
---|
| 177 | on a service basis for the E&P industry. The optic fibers |
---|
| 178 | are mass-manufactured by a number of companies with a variety of |
---|
| 179 | materials and designs for different applications. The |
---|
| 180 | 'Instrument Boxes' comprise a laser light source, an oven which |
---|
| 181 | provides a reference temperature, and photo-electric sensors which |
---|
| 182 | capture the backscattered light, along with digital circuitry which |
---|
| 183 | both controls the laser transmission and analyses the frequency and |
---|
| 184 | intensity of the backscatter. Instrument boxes and fibers can |
---|
| 185 | readily be interchanged. </P> |
---|
| 186 | <P>The transmission characteristics of optic fibers are dependent |
---|
| 187 | upon several factors in addition to temperature, which include their |
---|
| 188 | construction, physical deformation and chemical , particularly |
---|
| 189 | aqueous, contamination. For these reasons, calibrations of the |
---|
| 190 | equipment are routinely necessary to monitor the transmission |
---|
| 191 | characteristics.</P> |
---|
| 192 | |
---|
| 193 | <H4>Installation in Wellbores</H4> |
---|
| 194 | |
---|
| 195 | <P>The location of the source of the backscattered light is |
---|
| 196 | determined in terms of its distance along the fiber by the two-way |
---|
| 197 | transmission time and the velocity of light in the transmitting |
---|
| 198 | medium. It is therefore necessary to know how length along the |
---|
| 199 | fiber correlates to measured depth along the wellbore in which the |
---|
| 200 | fiber is installed. The foregoing information includes |
---|
| 201 | knowledge of the positions in the well and along the fiber where |
---|
| 202 | connections through casing shoes, packers and other features occur. |
---|
| 203 | All these can be assumed to remain constant between initial |
---|
| 204 | installation and mechanical interventions in the wellbore.</P> |
---|
| 205 | <P>There are several fiber configurations deployed in wellbores, |
---|
| 206 | illustrated in fig 2, which enable various calibrations to be made to |
---|
| 207 | the temperature data.</P> |
---|
| 208 | |

---|
| 211 | <H4>Calibrations</H4> |
---|
| 212 | |
---|
| 213 | <P>Two kinds of calibration are applied to DTS data. These are:</P> |
---|
| 214 | <UL> |
---|
| 215 | <LI><P STYLE="margin-bottom: 0in">factors pertaining to the |
---|
| 216 | Instrument Box such as the oven reference temperature, the number of |
---|
| 217 | launches being stacked to get a temperature value at the required |
---|
| 218 | resolution; |
---|
| 219 | </P> |
---|
| 220 | <LI><P>factors related to the fiber, including the (practically |
---|
| 221 | linear) differential attenuation along the fiber, and the refractive |
---|
| 222 | index of the fiber. |
---|
| 223 | </P> |
---|
| 224 | </UL> |
---|
| 225 | |
---|
| 226 | <P>Where the fiber may be installed in a well bore for several years, |
---|
| 227 | it is necessary to recalibrate these factors periodically in order to |
---|
| 228 | be able to compare reservoir temperatures over these periods.</P> |
---|
| 229 | <P>The Optical Time Domain Reflectometry (OTDR) technique provides a |
---|
| 230 | routine means of examining the condition of the fiber. OTDR |
---|
| 231 | consists of observing the attenuation of backscattered light in the |
---|
| 232 | frequency band of the transmitted Rayleigh waves. An OTDR |
---|
| 233 | profile is illustrated in Figure 3.</P> |
---|

| 239 | <H4>Measurements</H4> |
---|
| 240 | |
---|
| 241 | <P>The measurements produced by the Instrument Box for a temperature |
---|
| 242 | profile typically comprise a set of records containing contextual |
---|
| 243 | data followed by the temperature records. The contextual data |
---|
| 244 | identify the well, the equipment, the date and time, and various |
---|
| 245 | calibration data. Each temperature record contains the length |
---|
| 246 | along the fiber of the temperature sample, the computed temperature, |
---|
| 247 | and measurements of the Stokes and anti-Stokes intensities.</P> |
---|
| 248 | |
---|
| 249 | <P>There are many possible representations of the temperature data, |
---|
| 250 | and criteria for selecting among them included: conformance to data |
---|
| 251 | produced from DTS instrument boxes; minimal verbosity of the XML |
---|
| 252 | transfer files; re-use of existing, implemented data specifications |
---|
| 253 | which satisfied DTS requirements; conformance to consuming data stores |
---|
| 254 | and applications, and others. POSC recognised the high degree |
---|
| 255 | of similarity of DTS data with other types of well logs, and |
---|
| 256 | chose to re-use of the existing WITSML wellLog specification which met all currently |

---|
| 261 | <P>POSC has defined standards for DTS data to be transferred between |
---|
| 262 | the oilfield well site and offices of oil and service companies. The |
---|
| 263 | DTS data standard should simplify, but does not specify, subsequent |
---|
| 264 | storage and access models and processes. Thus, the |
---|
| 265 | standard should improve the overall process of controlling and |
---|
| 266 | optimizing production operations. The standard specifies both |
---|
| 267 | the content and the representation of the data, in other words, it |
---|
| 268 | covers both the data, and their meaning, that need to be transmitted |
---|

| 373 | website. </P> |
---|
| 374 | |
---|
| 375 | <P>DTS is modelled as follows:</P> |
---|
| 376 | |
---|
| 377 | <H3>Well and Wellbore</H3> |
---|
| 378 | |
---|
| 379 | <P>The DTS specification utilizes the WITSML well and wellbore schemas to provide all of the related well data. |
---|
| 380 | This includes information such as operator, geopolitical location, geographic location, well datum, status, etc.</P> |
---|
| 381 | |
---|
| 382 | <H3>Fiber</H3> |
---|
| 383 | |
---|
| 384 | <p>The fiber is intended to capture |
---|
| 385 | a description of the fiber as a material. Information about the |
---|
| 386 | installation and use of the fiber in the wellbore is captured in |
---|
| 387 | dtsInstalledSystem.</p> |
---|
| 388 | |
---|
| 389 | <pThe fiber contains two types of |
---|
| 390 | information. These will be described for information only. There should be |
---|
| 391 | no attempt to separate these two types of information</p> |
---|
| 392 | |
---|
| 393 | <p>The first is the information |
---|
| 394 | that would be found in a manufacturer's catalog. This is a technical |
---|
| 395 | specification. It includes information that would be applicable for any |
---|
| 396 | fiber of the type described.</p> |
---|
| 397 | |
---|
| 398 | <p>Secondly, it includes |
---|
| 399 | information about a specific spool of the fiber. This additional |
---|
| 400 | information would be spool number, length of fiber on the spool, and any |
---|
| 401 | factory calibration or quality checks that were done.</p> |
---|
| 402 | |
---|
| 403 | <H4>Generic Usage elements</H4> |
---|
| 404 | |
---|
| 405 | <p class="MsoBodyText"><span lang="EN-US">There are three generic elements that |
---|
| 406 | can be used to characterize the fiber.</span></p> |
---|
| 407 | <UL> |
---|
| 408 | <LI> |
---|
| 409 | <p><b>type</b> - The |
---|
| 410 | purpose of the type element is to classify the fiber, using various |
---|
| 411 | classification systems. A specific element, mode, allows the classification of |
---|
| 412 | singlemode or multimode. The type element allows other classifications to be |
---|
| 413 | made. The type element contains an optional attribute, classType. This, along |
---|
| 414 | with the classification, is a way of transferring additional information</p> |
---|
| 415 | |
---|
| 416 | <p>Example: <type classType=flexibility>rigid</type></p> |
---|
| 417 | </LI> |
---|
| 418 | |
---|
| 419 | <LI> |
---|
| 420 | <p><B>parameter</b> - |
---|
| 421 | This element allows any additional information that might be useful. These |
---|
| 422 | consist of name/value pairs, along with optional description and uom attributes. |
---|
| 423 | This is patterned after the element that is used in wellLog to capture uncontrolled |
---|
| 424 | parameters.</p> |
---|
| 425 | </LI> |
---|
| 426 | |
---|
| 427 | <LI> |
---|
| 428 | <p><b>factoryCalibration</b><span lang="EN-US"> - |
---|
| 429 | Any quality control or calibration tests that were run can be captured in this |
---|
| 430 | information. This does <b>not</b> include tests that are run in conjunction with |
---|
| 431 | installing the fiber, or obtaining measurements. There is a similar calibration |
---|
| 432 | capability with these objects.</span></p> |
---|
| 433 | </LI> |
---|
| 434 | </UL> |
---|
| 435 | |
---|
| 436 | <h4>Installation History</h4> |
---|
| 437 | |
---|
| 438 | <p class="MsoBodyText"><span lang="EN-US">The installationHistory element allows |
---|
| 439 | previous uses of the fiber to be recorded. If the fiber was installed in a |
---|
| 440 | wellbore at one time, removed, and installed in the same or different wellbore, |
---|
| 441 | the previous installation may be referenced. This is an optional element, but is |
---|
| 442 | included to allow the sender to give quality control information.</span></p> |
---|
| 443 | |
---|
| 444 | <h3>Instrument Box</h3> |
---|
| 445 | |
---|
| 446 | <p class="MsoBodyText"><span lang="EN-US">Like the fiber, the |
---|
| 447 | instrumentBox has two types of information. The first is the |
---|
| 448 | manufacturer's catalog set, which could be used to describe a generic |
---|
| 449 | instrument box of the type being used. The other information is related to |
---|
| 450 | a specific instrument box that is being used in the DTS system.</span></p> |
---|
| 451 | |
---|
| 452 | <h4>Generic Usage elements</h4> |
---|
| 453 | |
---|
| 454 | <p class="MsoBodyText"><span lang="EN-US">The <b>instrumentBox</b> has two |
---|
| 455 | generic elements to capture information. There is a <b>parameter</b> |
---|
| 456 | element which allows any information not specifically covered in the given |
---|
| 457 | elements. The other is the <b>factoryCalibration</b> element which allows |
---|
| 458 | specific calibration information that was done at the factory or at the |
---|
| 459 | bench. As with the case of the fiber, this is not intended to include |
---|
| 460 | calibrations that are done in conjunction with the installation of the |
---|
| 461 | fiber and instrument box in a wellbore, or calibrations done at |
---|
| 462 | measurement time.</span> |
---|
| 463 | |
---|
| 464 | <h3>Fiber locations downhole</h3> |
---|
| 465 | |
---|
| 466 | <pThe measurements made are |
---|
| 467 | written as a table of information (using the WITSML wellLog) that has, at a minimum, length along fiber versus |
---|
| 468 | temperature. This must be converted to measured depth versus temperature for |
---|
| 469 | use.</p> |
---|
| 470 | |
---|
| 471 | <p>The information about the length |
---|
| 472 | along fiber versus measured depth |
---|
| 473 | is recorded when the fiber is installed. This information is recorded in |
---|
| 474 | the <b>dtsInstalledSystem</b> object using the element, <b>wellboreFiberSchematic.</b> |
---|
| 475 | This element is key, because it stores the relationship between length |
---|
| 476 | along fiber and measured depth at certain, important points of the |
---|
| 477 | wellbore and fiber installation.</p> |
---|
| 478 | |
---|
| 479 | <p>When a measurement is made, the |
---|
| 480 | data, as mentioned above, consists of the length along fiber. This |
---|
| 481 | information must be related to the wellboreFiberSchematic in order to |
---|
| 482 | obtain the measured depth information. However, it is generally not the |
---|
| 483 | case that the length along fiber in the <b>wellboreFiberSchematic</b> and |
---|
| 484 | the length along fiber in the measured data table have the same zero |
---|
| 485 | point. In order to match these two arrays, it is necessary that both the |
---|
| 486 | dtsInstalledSystem/wellboreFiberSchematic and the <b>dtsMeasurement</b>/ <b>fiberDefinedPoint</b> |
---|
| 487 | record a common point. A good policy for the DTS community would be to |
---|
| 488 | define which specific point should be used as the common point.</p> |
---|
| 489 | |
---|
| 490 | <p>In addition to the specific |
---|
| 491 | point, it is necessary to capture the recording direction for a |
---|
| 492 | U-shaped installation. This is done in the dtsInstalledSystem/fiberEndPoint |
---|
| 493 | by giving names to the ports. The dtsMeasurement/fiberEndConnected refers |
---|
| 494 | to this port using the same name.</p> |
---|
| 495 | |
---|
| 496 | |
---|
| 497 | <h3>DTS Measurements </h3> |
---|
| 498 | |
---|
| 499 | <P>These measurements are part of the wellbore object and use the wellLog object |
---|
| 500 | to capture the temperature - depth profiles. Instances of the wellLog object may also carry |
---|
| 501 | the OTDR |
---|
| 502 | (Optical Time Domain Reflectometry) data.</P> |
---|
| 503 | |
---|
| 504 | |
---|
| 505 | <h3>Composite Schema</h3> |
---|
| 506 | |
---|
| 507 | <P>In addition, WITSML includes an overall composite schema |
---|
| 508 | which has been defined to allow data from all of the data object |
---|
| 509 | schemas to be included in one document. This object is shown with |
---|
| 510 | only DTS objects and the wellLog object incorporated so that it |
---|
| 511 | becomes evident how the well, wellbore, and dts data can be |
---|
| 512 | incorporated into a single message. The hierarchical model for the |
---|
| 513 | composite is as follows:</P> |
---|
