Start of first offshore well in Abu Dhabi for Shuwaihat project / Own stand at the largest oil and gas conference in the Middle East region (Hall 6, Stand 6256) Kassel/Abu Dhabi, 14-Nov-2016 — /EuropaWire/ — Germany’s largest internationally active oil and gas producer will be showcasing its activities and technological expertise at the “Abu Dhabi International Petroleum Exhibition and Conference” (ADIPEC). Right on time for the annual meeting, Wintershall spuds its first offshore well for the Shuwaihat project in Abu Dhabi. In July 2015, Wintershall successfully completed the first onshore drilling of the sour gas and condensate field Shuwaihat together with its partner ADNOC and the Austrian OMV. After compiling and analyzing the data from the onshore field SH-5, Wintershall now spudded the first offshore well SH-6. “We have successfully completed the first project phase and are now ready to carry on with the planned activities, namely spudding the offshore well SH-6. Our technological expertise helps us to carry out drilling activities in challenging geological conditions in accordance with the highest HSE standards,” explains Uwe Salge, General Manager for Wintershall Middle East. Second well for Shuwaihat project: Focus on HSE and efficiency In order to establish a supply base, Wintershall has opted for a bespoke solution rather than a standard approach and has developed the local “Mugharraq” port for its operations. This way, Wintershall is saving time and money by building its first E&P supply base. For the offshore well SH-6, Wintershall has also implemented an extensive safety concept. For instance, Wintershall together with ADNOC has set up an extended oil spill response system, since operations are close to the shore. The Shuwaihat field is situated in the western region of Abu Dhabi, about 25 kilometers west of the industrial town of Ruwais. The reservoir evaluation includes up to three field appraisal wells and a 3D seismic survey. The third planned well (SH 7) will also be drilled offshore. Wintershall’s presence at ADIPEC underlines the strategic importance of the Middle East. The company has been active in the region for several years now and plans to do so in the future. For this purpose, in 2010 the company opened a regional representative office in Abu Dhabi. In June 2012, Wintershall signed an agreement with the Abu Dhabi National Oil Company (ADNOC) and the Austrian OMV company regarding the technical appraisal of the Shuwaihat sour gas and condensate field. As the operator, Wintershall is relying on its extremely high HSE standards and more than 40 years of experience in the safe development and production of sour gas fields. In 2015, a Memorandum of Understanding was also signed with ADNOC for a cooperation on a chemical EOR project, underlining the importance of research & development as well as technological expertise. In line with this year’s theme “Strategies for the new energy landscape”, Wintershall CEO Mario Mehren will participate in the Global Business Leaders Session to discuss “The Golden Age of Gas and LNG” with Gazprom’s Alexander Medvedev and Occidental Petroleum’s Vicky A. Hollub. Wintershall will also be showcasing its expertise and worldwide activities at its exhibition stand (Hall 6, Stand 6256). The company will provide “expert briefings” where Wintershall employees will present different aspects of their work. These presentations will take place up to three times a day in order to give a larger public at ADIPEC the opportunity to listen to the presentations. In addition, Wintershall has also submitted several papers and will present its findings during the official technical conference organized by the Society of Petroleum Engineers (SPE). Wintershall Holding GmbH, based in Kassel, Germany, is a wholly-owned subsidiary of BASF in Ludwigshafen. The company has been active in the extraction of natural resources for 120 years, and in the exploration and production of crude oil and natural gas for over 85 years. Wintershall focuses on selected core regions where the company has built up a high level of regional and technological expertise. These are Europe, Russia, North Africa, South America, and increasingly the Middle East region. The company wants to expand its business further with exploration and production, selected partnerships, innovation and technological competence. Wintershall employs about 2.000 staff worldwide from 50 nations and is now Germany’s largest, internationally active crude oil and natural gas producer. Wintershall. Shaping the future.

KASSEL, 13-Feb-2017 — /EuropaWire/ — From the Moskva to the Neva estuary: Wintershall is moving its Russian branch office, which currently has around 90 employees, from Moscow to St. Petersburg in August 2017. “Relocating Wintershall’s Russian branch office to St. Petersburg represents another step towards strengthening our cooperation with Gazprom. Our partnership is shaped by trust and stability. We therefore share the firm conviction that our presence in the same city will enable us to perform the tasks arising from our joint activities even more efficiently,” Thilo Wieland, Member of the Wintershall Board of Executive Directors, underlined. Gazprom has already moved its company headquarters to the northernmost metropolis in the world. Winterhall has been cooperating with Gazprom for more than 25 years. During this time a series of projects of strategic significance have been implemented, including the delivery of Russian natural gas directly to Europe. Furthermore, Wintershall was the first German company to participate directly in the joint production of natural gas in Siberia. The joint ventures OAO Severneftegazprom and ZAO Achimgaz alone produced 30 billion cubic meters of natural gas in 2016 and have thus become pillars of the European natural gas supply. Russian-German partners Wintershall and Gazprom are currently preparing the development of Blocks 4 and 5 of the Achimov formation in the Urengoy natural gas field. Wintershall Holding GmbH, based in Kassel, Germany, is a wholly-owned subsidiary of BASF in Ludwigshafen. The company has been active in the extraction of natural resources for 120 years, and in the exploration and production of crude oil and natural gas for over 85 years.

This paper describes the refraction statics processing based on tomographic inversion of a 503km2 subset of a modem marine 3D seismic dataset acquired in very shallow waters offshore Qatar. The objective of the seismic survey was imaging of the Mesozoic interval from 0.4-1.8 seconds two way travel time below sea level. Characteristic for the study area is the presence of local shoal bodies, often associated with coral reefs at sea bottom and in the near surface below sea bottom. These features can have a significant effect on the imaging of seismic data and therefore the prospectivity assessment of the exploration area as their typically high velocity introduces distortions in the timing of events, i.e. false structures might be generated or true structures suppressed. Compensating for the reef structures in the statics model results in a more accurate image of the subsurface. This was achieved by applying first-arrival travel time tomography to obtain the shallow velocity information needed to calculate refraction statics corrections. Refraction statics tomography uses the first break travel time picks of the seismic data to derive a velocity model of the near surface. This velocity model is then used to generate static shifts to correct the data to a final datum plane using a known replacement velocity, thereby removing the velocity variation caused by the sea bottom and near surface features. The tomographic inversion algorithm for land data was adapted to marine data by including a new option to freeze the water column velocity, which should be constant and not taken into account in the velocity updates. Refraction statics tomography is superior to conventional refraction statics because the inverted velocity model reveals the lateral and vertical velocity variations in the near surface. The dense shot and receiver spacing of this data set provided a large number of first break picks for the tomographic inversion process and resulted in a stable near surface velocity model. The computed static shifts corrected for some of the time shifts observed below the sea bottom features. The application of refraction statics tomography in this study provided an improved subsurface image compared to the original processing.

An integrated seismic reservoir characterization study is presented on data from the Yuzhno Russkoye gas field. The Upper Cretaceous reservoir sands have excellent porosities and are buried at a depth of about 1 km. The workflow includes amplitude mapping, trace classification, acoustic impedance inversions, crossplotting and reservoir modeling. Observations are calibrated with 88 wells (logs and core description). Cross plots of porosity versus acoustic impedance reveal relationships that match the log data in the blind holes rather well. Fluid contacts in the main two gas-bearing intervals coincide with flat events on seismics. Biot-Gassmann fluid replacement modeling demonstrates a consistent difference in acoustic impedance at the gas-water contact, confirmed by the inversion results. The gas-bearing reservoirs coincide with distinct bright spots. Forward modeling indicates a polarity flip near the fluid contact for the Cenomanian reservoir (AVO class 2). Sweet spots are outlined on various attribute maps. The reported gas production in the field is consistent with the reservoir inhomogeneities identified by mis study. The modelling and mapping results serve as input for the shared earth model and the subsequent reservoir simulation.

Fault and Top Seals: From Characterization to Modelling | Year: 2012
Geomechanical and kinematic modelling techniques were applied to support the trap integrity risking process for a North Sea appraisal project in faulted Carboniferous clastic strata. A key issue here is whether clay smearing has the potential to provide a valid seal across reservoir compartmentalizing faults. Standard fault seal analysis workflows use the critical clay smear factor (CCSF) to assess the potential for fault sealing. However in a mechanically layered sequence, the CCSF will vary between layers depending on the position of the layer within the overall stratigraphy and the rate of fault propagation. We use a combination of mechanical and kinematic models to predict (a) where the faults will nucleate in a mechanically layered sequence and how fast they will propagate through it, and (b) the resultant fault propagation folding in shale layers and hence the CCSF for each shale layer. We show that the development of clay smears is dependent on both the surrounding stratigraphy, the depth of burial at the time of faulting, and the rate of fault propagation.

Fault and Top Seals: From Characterization to Modelling | Year: 2012
Understanding the impact of faults on reservoir compartmentalization, hydrocarbon migration and fluid contacts is a key for the exploration and development in structurally complex areas of the North Sea and requires an integrated analytic approach. The structure discussed here is located in the Broad Fourteens Basin and underwent a complex multi-phase structural evolution of extensional episodes followed by contractional phases. Two different gas-water contacts were encountered in fault bounded compartments of Bunter reservoirs. Gas pressure points lie on the same gradient in both compartments whereas water pressure points indicate differently pressured aquifers. Another key observation is that the compartments are under-filled. The integrated trap analysis applied, allows proposing a two-phase scenario in order to explain the present day trap configuration and the observed gas-water contacts. Initially gas charging of the structure took place and resulted in a single gas-water contact. During the subsequent contractional event one compartment was uplifted along the main fault of the structure preserving the trap integrity. The gas pressure was able to equilibrate during geologic time across an upper low Vshale window but no pressure equilibration was possible within the water leg, leading to the water overpressures observed in the uplifted compartment.
