The Use of Open Flow Potential Test Data in Determining Formation Capacity and Skin Factor

An open-flow helium cryostat for single-crystal X-ray diffraction experiments capable of reaching 14 K has been developed using off-the-shelf components. Solid/liquid air build-up is prevented using the transfer-line helium back-flow and a heated nozzle. The system has run for over 30 h with no frost build-up. The effectiveness of the system has been demonstrated using test data for oxalic acid, terbium vanadate and dysprosium vanadate.

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.

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