A Stability Analysis of Two Horizontal CBM Wells in the Deep Mannville Coals, Alberta Basin, Canada
Abstract This study describes the main technical challenges encountered while drilling the first horizontal coalbed methane well ever attempted in Canada. The well was drilled in the deep (>1,300 m), low-permeability (1–3 md) coals of the Lower Cretaceous Mannville Formation in the central Alberta Plains. The study also discusses the investigation that

Advances in Technology of CBM Horizontal Well Completion in Deep Area
Abstract In 2011, a deepest horizontal Coalbed Methane (CBM) well in China, with a total vertical depth in excess of 1100m, was successfully drilled by Shell China E&P Co. Ltd (SCEPCo). The well, located in the East Ordos Basin, achieved a total 'in-seam' length of nearly 3600 m.

Deep learning for quark–gluon plasma detection in the CBM experiment
Classification of processes in heavy-ion collisions in the CBM experiment (FAIR/GSI, Darmstadt) using neural networks is investigated. Fully-connected neural networks and a deep convolutional neural network are built to identify quark–gluon plasma simulated within the Parton-Hadron-String Dynamics (PHSD) microscopic off-shell transport approach for ...

Study on the Fracture Propagation Mechanism in Deep CBM Reservoirs
ABSTRACT: The matrix permeability of deep coalbed methane (CBM) reservoirs is extremely low, but they are abundant in bedding and cleats structures. Hydraulic fracturing is the most effective method for exploiting deep CBM reservoirs. Due to the characteristics of deep coal seam burial and high construction pressure,

Case Study: CO2 Foam Fracturing Accelerate Deep CBM Reservoir Development in Ordos Basin
Abstract The Ordos Basin is located in northwest China, where there is perennial drought, little rainfall, and a fragile ecological environment. Recently, operators have increased their exploration and production efforts on a deep coalbed methane (CBM) reservoir [true vertical depth (TVD) >2000 m], which is the cornerstone to ...

Abstract Deep coalbed methane (CBM) exploration presents unique challenges in reservoir characterization, particularly when dealing with thin coal seams. This study introduces a novel application of two-dimensional Convolutional Neural Network (2D CNN) based seismic impedance inversion for characterizing the No.
