Coalbed Methane: Clean Energy for the World

As a global resource, coalbed methane holds great potential, and countries with coal deposits are actively pursuing its development. The oil industry is playing a major role in improving the recovery economics of this resource with new technologies for all phases, from evaluation to production. This article presents several recent developments in the evaluation, drilling, completion and production of this unconventional energy supply.

Basin and Petroleum System Modeling

Basin and petroleum system modeling tracks the evolution of a sedimentary basin and its fluids. This article explores the petroleum system concept and describes the types of information required to model the dynamic processes that lead to creation of hydrocarbons and their eventual accumulation. Case studies demonstrate how such modeling helps establish fluid presence and type and assess exploration risk before drilling.

Multiphase Fluid Samples: A Critical Piece of the Puzzle

Reliable metering of multiphase flow has been available for more than a decade. But an inability to capture and analyze representative fluid samples without first separating the phases has, until recently, hindered the full realization of its potential. A new multiphase sampling tool overcomes that hurdle.

Looking Deep into the Reservoir

With an electromagnetic transmitter in one well and an array of receivers in another, a new reservoir monitoring system is helping map the distribution of formation resistivity between wells. The results form the basis for crosswell tomographic images that assist asset managers in locating bypassed pay or mapping flow through a reservoir.
