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 |

125 | acknowledges the availability and use granted by Shell International |

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 | |
---|
209 | <P><IMG SRC="dtsFiberConfigurations.jpg" NAME="Graphic2" ALIGN=BOTTOM width=601 height=425 BORDER=0></P> |
---|
210 | |
---|
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 |
---|
257 | known requirements for DTS data.</P> |

260 | |
---|
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 |
---|
269 | and what format they should be in. |

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> |

403 | <H4>Generic Usage elements</H4> |

---|
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> |

---|
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> |

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 |

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> |

1188 | <P>The wellLog object is used to define large tables of data. Each column is represented by a curve. |
---|
1189 | The 'data' element within cs_wellLogData.xsd represents one row in the table. The wellLog can actually |
---|
1190 | contain multiple tables of data where, for example, one block would represent a table for one pass in a |
---|
1191 | wireline run. For use with DTS data |
---|
1192 | there will normally be only one block.</P> |
