An assessment framework for selecting optimal drilling and completion, forecasting and operating procedures in low permeability coals. Themes covered: low permeability coal drilling and production alternatives; production forecasting and operating procedures; and, economics and technical feasibilty. Arrow Energy Limited has been exploring for and producing from moderate to low permeability coals for over eight years, both in Australia and internationally. Arrow has developed a systematic approach to assessing the optimal drilling and completion, forecasting and operating procedures to evaluate the best appraisal and development options. Following the confirmation that the coal resource is of low permeability (less than 5mD) the selection of the drilling and completion strategies is inter-linked with the expected production and operating procedures. This paper summarises the approach taken by each of these discipline areas and maps out the key alternatives, data requirements and selection criteria used to recommend a production pilot in a low permeability environment. The first stage of the assessment is to review the drilling alternatives. This includes consideration of horizontal versus deviated or vertical wells, wellbore stability and solids production conditions, stimulation requirements and the production string, including artificial lift. Production forecasting is conducted with due regard to the technical alternatives screened as part of the drilling assessment. The quality of the forecast will be determined by the available data and the use of the appropriate forecasting tools ranging from analogue assessments, simple single well modelling through to 3D reservoir modelling. Finally, the production procedures appropriate for the well will be selected based on the well configuration and forecast deliverability as well as regional geology and geomechanics. This framework ensures that a consistent methodology is applied for selecting well type and operations that maximises the flow potential from our low permeability coals while ensuring due consideration to economics and technical feasibility.

Special Composition

Puguang gas field is the first deeply buried formation and high-sulfur natural gas field on developing. Due to the special composition of natural gas, the deliverability evaluation has a lot of problems. So it is very difficult to conduct a deliverability evaluation with the pressure of well bottom. In this study, an equation of wellhead deliverability is established by testing data. And it is evaluated through the wellhead open flow potential and absolutely open flow potential which is determined by another deliverability equation from well testing data. Results show that there exists a good linear correlation between wellhead open flow potential and absolutely open flow potential in each well of Puguang gas field. In addition, through applying this correlation, absolutely open flow potential can be calculated through wellhead deliverability equation, which provides a new method to study deliverability.

<p>Sumur X-11 merupakan sumur gas yang terindikasi terdapat <em>skin </em>disekitar lubang perforasi, sehingga pada sumur X-11 dilakukan <em>acidizing</em>. Untuk mengetahui <em>acidizing </em>yang dilakukan berhasil atau tidak, maka dilakukan uji sumur. Uji sumur yang dilakukan adalah uji <em>pressure build up</em> dengan menggunakan metode <em>Pressure Derivative </em>dan <em>Horner</em> <em>Plot</em>. Selain itu dilakukan analisis uji deliverabilitas dengan menggunakan metode <em>isochronal test</em>,. Uji deliverabilitas dilakukan untuk mengetahui kemampuan suatu sumur untuk berproduksi (AOFP). Hasil  uji <em>pressure build up test</em> pada sumur X – 11 didapatkan nilai permeabilitas, faktor <em>skin, radius of investigation </em>dan <em>flow efficiency</em> sebesar 9,868 mD, 0, 554,77 ft, dan 1,34. <em> </em>Hasil uji deliverabilitas sumur X-11 didapatkan nilai <em>Absolute Open Flow Potential </em>(AOFP) sebesar 327227 Mscf/D. Nilai <em>skin</em> yang negatif menunjukkan bahwa <em>acidizing </em> yang dilakukan pada sumur X-11 berjalan dengan baik.</p>
