Integrating surface seismic, microseismic, rock properties and mineralogy in the Haynesville shale play
Gabino Castillo, Simon Voisey, Kevin Chesser, Norbert van de Coevering, Antoine Bouziat, Guy Oliver, Chi Vinh Ly and Lih Kuo illustrate a workflow integrating reservoir and geomechanical properties obtained from pre-stack seismic inversion and incorporating stress and fracture information extracted from azimuthal analysis of the seismic data.

Dynamic reservoir characterization using 4D multi-component seismic data and rock physics modelling in the Delhi Field, Louisiana
Authors Carla Carvajal, Indah Putri and Tom DavisCarla Carvajal, Indah Putri and Tom Davis use time-lapse AVO fluid inversion to quantify the probability of CO2, oil and water in the reservoir and demonstrate that reservoir heterogeneities and pore pressure gradients control the CO2 flow.

Diffraction imaging applied to pre-existing 3D seismic data to map fracture corridors in an unconventional play
Authors Marianne Rauch-Davies, Kostya Deev, Danil Pelman and Maria Kachkachev-ShuiferMarianne Rauch-Davies, Kostya Deev, Danil Pelman and Maria Kachkachev-Shuifer demonstrate how naturally occurring fractures in tight rocks can be detected using conventionally acquired seismic data.

Distributed Acoustic Sensing – a new tool for seismic applications
Authors Tom Parker, Sergey Shatalin and Mahmoud FarhadiroushanDistributed optical fibre sensors are established tools in the energy industry, finding many applications for production optimisation and integrity monitoring. Recently, a new class of instrument, the Distributed Acoustic Sensor (DAS), has been launched which adds seismic imaging to the list of energy industry applications. In this paper, we describe one such distributed acoustic sensor (named the iDAS) and demonstrate, through a series of lab experiments, the signal quality and performance that can be achieved. We show data which demonstrates the capability of the iDAS to measure the true acoustic signal (amplitude, frequency and phase) at all points along the sensing fibre length. We also compare the iDAS data with data collected from conventional point sensors and detail experiments which validate key performance criteria. We follow the lab experimental validation of the iDAS with a series of lab and field demonstrations. The lab demonstrations encompass localisation (ranging) of events away from the sensing fibre (for security applications) and acoustic imaging through the formation of a large acoustic camera using a single sensing fibre. The field demonstrations show comparisons of iDAS and geophone measurements in a surface seismic survey and improvements made by stacking shot records from an offshore VSP survey.

Recent emerging paradigms in hydrocarbon exploration
Authors J.J. Biteau, M. Blaizot, Dominique Janodet and Philippe de ClarensInteresting points can be made about hydrocarbon volumes discovered in the past decade: - 350 bboe of 2P (Proved and Probable) discovered volumes were found, and 91 of the fields have 2P volumes in excess of 500 million boe (‘elephant’) totalling approximately 200 billion boe, based on publicly available information. - This compares with 120 bboe in the period 1991-2001, and 140 bboe in the period 1981-1991 (From AAPG Memoir data) - six petroleum plays can be defined and ranked against the corresponding volumes: - Carbonates below salt and Large Delta Systems account for more than 85% of the discovered volumes; - A new play concept: Abrupt Margins has been proven, with the Jubilee Field in Ghana (disc 2007). Foinaven Field (West of Shetlands, disc. 1991) also goes into this category; - New Exploration Techniques will be needed in mature plays such as Foreland fold and Thrust belts. These discovered volumes are far from negligible in sustaining current worldwide production (2013) of almost 90 mmboe/d and 400 bcf/d, rates that will increase to 100 mboe a day by 2020 for oil and to 500 bcf/d by 2030 for gas, depending on demand and investment rates.
