Paper Number: SPE-192017-MS
... Abstract In this paper, a fracture mechanics model that deals with fracture growth in layered low-permeability rocks is presented and applied to hydraulic fracturing stimulation of coal seam gas reservoirs. The model uses the conventional pseudo-3D treatment by which the vertically planar...

... Typically, the SIS pairs were drilled with 1000 to 1500m in-seam lateral length and 1500m nominal areal well spacing. Although there is no 3D seismic and only widely spaced 2D seismic data of varying vintage and quality over the field, on average over 1000 meters in seam length (approximately 90...

Paper Number: SPE-191904-MS
... Abstract Building a representative static model for predicting and monitoring performance of coal seam gas fields presents several complex and unique challenges. The individual reservoirs possess very different coal architectures, often with highly complex seam splitting, amalgamating...

... eventually been used to improve the production forecasting. In particular, pressure data confirmed that aquifer activity was limited and pointed out a typical multi-layer with cross-flow production response which is consistent with the known geology on Fairview (alternating coal seams of contrasted...

... with extensive coal seam gas development experience to pursue aggressive short term reserve growth targets. Plans were in place to install PCP completions in the vertical wells and tie the wells into a pre-installed water and gas gathering system as soon as the first horizontal well was drilled...

... Abstract Spurred by the commercial success of coalbed methane activity in USA, India initiated evaluating its coal bearing basins for their coalbed methane potential in 1992. In a short span of five years it tested and flowed coalbed methane from one of the coal seams of Barakar Formation...

Paper Number: SPE-50061-MS
... Abstract Three propped hydraulic fractures, placed in coal seams from vertical wells, were recently mapped as the coal mine workings passed through the site of the wells. The fractures were propped with sand and, in each case, the geometry of the propped fracture was mapped during mining...

... Abstract Permeability anisotropy in a coal seam in the Bowen Basin has been measured by a multiple well interference test. The degree and orientation of the anisotropy was apparently influenced by coal structural features on various scales. Simulations of the field observations using a two...

... An integrated program of characterisation, stimulation, and post-stimulation trial production has been completed in three coal seams intersected by two HQ-size (96 mm diameter) boreholes located adjacent to Appin Colliery in NSW. Data on stress, seam permeability and pressure, formation mechanical properties...

... to base an assessment of a well's potential production performance. To minimise test time and properly isolate the different seams, resettable slimhole packer systems have been developed for different sized holes. This paper will discuss (1) the early testing practices, such as the slug testing approach...

... located south of Newcastle, NSW. The treatments fractured the 3- metre thick, 220-metre deep Great Northern coal seam and were designed to provide a direct comparison between a borate-crosslinked gel and a water treatment. The fracture geometries were mapped during mining of the coal seam. Geologic...
