Technical Meeting E Poster for August 2017Lagos

Topic: Impact of Full Waveform Inversion (FWI) on Fault Shadow Imaging: A Niger Delta Case Study
The Lagos August Technical/Business Meeting was held on August 16, 2017 at the Grand Ballroom of Eko Hotel and Suites, Victoria Island, Lagos. The technical presentation was made by Auwal Ya'u, a Chief Geophysicist with IDSL and the Acting Deputy Manager, Marine, IDSL Data Processing, Port Harcourt. The topic presented was "Impact of full waveform inversion (FWI) on fault shadow imaging: A Niger Delta case study - Yoho field". The project was executed by IDSL in conjunction with Western Geco. The major challenges in the Yoho field seismic was poor fault imaging, loss of frequencies, shallow gas, high velocities and very low velocity areas. In this environment, conventional tomography model building methods alone proved inadequate to resolve the highlighted challenges. However, FWI was used to derive high-resolution velocity models that define strong lateral subsurface heterogeneities associated with fault shadows mostly present within vicinity of shallow gas anomalies. The data was migrated using kirchoff prestack migration algorithm. FWI utilizes frequency, amplitude and phase information in recorded seismic data to estimate high-resolution models of subsurface properties. FWI models produces synthetic seismograms (modeled data) that is used to improve imaging of the recorded data. Input data used in this work was narrow azimuth towed streamer dataset. A multi-scale strategy was followed via first inverting lowest frequencies, progressively increasing input data bandwidth and accordingly updating the velocity profiles. The derived highly-resolved FWI velocity models was then followed by two high resolution tomography updates to better image deeper events. The final velocity model was used by KAPSDM algorithm to provide better quality images. The result of the FWI was crispier, sharper, clearer and generally improved the imagery of the faults and the entire seismic vintage. Alternatively, it was suggested from the audience that for improved seismic resolution, it is best to acquire wide azimuth/ broadband azimuth seismic data. The meeting was sponsored by Nigerian National Petroleum Corporation (NNPC)/Integrated Data Services Ltd.

NAPE Lagos July Technical Meeting

Topic: Opportunities and Challenges of Divested Asset Management - NPDC's Experience
July Technical Meeting: NAPE’s July Technical Meeting was held on July 26, 2017 at the Grandball Room, Eko Hotel and Suites, Victoria Island, Lagos. The technical presentation was made by Mr. Kareem Folorunso,Manager, NPDC Onshore Assets. The topic presented was "Opportunities and Challenges of Divested Asset Management – NPDC’s Experience”.
The event began with the traditional safety briefing anchored by Emmanuel Egbele, NAPE Publicity Secretary.  He stressed the value of vigilance and safety awareness in the work place.
Mr. Kareem’s presentation chronicled the beginnings of the oil industry from the late 1950’s up until the creation of NNPC tasked with managing Government’s majority interests in existing assets operated by the IOC’s and how this participation morphed into the creation of Nigerian Petroleum Development Company (NPDC). He highlighted the perspective of NPDC with regards to the opportunities in managing divested petroleum assets as well as the plethora of challenges that they encountered in achieving success in the operations.
He started by listing the reasons for divestment as:  production decline, high operating costs, community unrest etc., while highlighting the key attractions the assets presented.The divestments began from 2009, asset sales by SPDC, BG, NAOC, Total, Petorbras, Chevron, ConocoPhillips assets comprised OPLs 232, 284, 286; OMLs 4, 26, 30, 34, 38, 40, 41, 42 and 60.  These opened opportunities for indigenous companies to take on key role in growing the Nigeria oil and gas industry through exploration and production operations.  At the time, many industry watchers welcomed the move as a boost to the Nigerian content initiative.  The attractiveness of the divestments was seen in opportunities for quick wins in already existing production capacity, quick cash flow, an abundance of field data enhancing further development, gas potentials, proximity to third party facilities as well as anticipated growth of support institutions (local oil field service providers, banks, insurance etc).
However, four years down the line, the resolve of the NPDC to deliver value on these assets was tested.Key among these challenges included: poor condition of inherited surface facilities across the OMLs, youth unrest, militant activity, vandalization, insecurity, no community development projects; while from the NPDC internal standpoint, challenges such as organizational structure, leadership structure, poor data quality, etc. compounded the dilemma.  In addressing these challenges the NPDC worked out mitigation strategies that yielded results and scored successes in delivering value such as: growth in status to become a medium player in the industry; highest gas producer with the 4th largest gas reserves in the country(reserves growth from 2Tscf to 18.4Tscf); grew oil reserves from 313MMstb to 3.168Bstb; condensate reserves from 60MMstb to 330MMstb; repairing and returning the 87km Trans Forcados Pipeline to operational efficiency, supply of stable, constant power to host communities etc.
