ExxonMobil, Hess Announce Oil Discovery Offshore Guyana
ExxonMobil and the Hess Corporation announced an eighth oil discovery offshore Guyana at the Longtail-1 well, creating the potential for additional resource development in the southeast area of the Stabroek Block. The companies said approximately 78 meters of high-quality, oil-bearing sandstone reservoir was encountered. The well was drilled to 5,504 meters depth in 1,940 meters of water by the Stena Carron drillship on May 25, 2018. The Longtail-1 well is located approximately 5 miles west of the Turbot-1 well and follows previous discoveries on the Stabroek Block at Liza, Payara, Liza Deep

Liza, Payara, Snoek, Liza Deep and Turbot, which are estimated to total more than 3.2 billion recoverable oil-equivalent barrels. ExxonMobil affiliate Esso Exploration and Production Guyana Ltd. began drilling the Ranger-1 well on November 5, 2017 and encountered approximately 70 meters of high-quality, oil-bearing carbonate reservoir. The well was safely drilled to 6,450 meters depth in 2,735 meters of water. “This latest success operating in Guyana’s significant water depths illustrates our ultra deepwater and carbonate exploration capabilities,” said Steve Greenlee
Petrobras' Production Crosses 1 bln barrels
are lifting 25,000 barrels per day, and productivity is up 30% from 2010. As a result, Petrobras has been able to interconnect fewer wells per production system. Pre-salt oil production is very important for the company’s financial recovery, representing large-scale production of excellent quality oil for refining, for lifting costs of less than US$8 per barrel. Today, thanks to the contributions of just 11 dedicated systems, nine in Santos Basin and two in Bacia de Campos, pre-salt already accounts for nearly 50% of the production led by Petrobras and around 35% of the company’s own
Petrobras Begins Early Production in Sépia Pre-salt
test period. Deployed in waters of approximately 2,200 meters depth, the FPSO is connected to the 1-RJS-691 well and will remain in its current location for 180 days. This is the fourth Early Production System set up in the Rights Transfer area of the Santos Basin. The oil is of good quality oil (26º API) and will be transported by shuttle tankers. The Sépia Early Production System is designed to collect technical data on the behavior of the reservoirs and oil outflow through underwater pipes, as well as other data. This will provide support for the development of
Cairn Confirms Successful Senegal Appraisal
API oil quality as seen in SNE-1 The SNE- 2 well is located in 1,200m water depth and is approximately 100 kilometres (km) offshore in the Sangomar Offshore block, reached the planned total depth (TD) of 2,800m below sea level (TVDSS). The well has been appraising the 2014 discovery of high quality oil in the SNE-1 well, some 3 km to the south. Cairn Energy Chief Executive Simon Thomson said, "We are delighted with the results of the SNE-2 well and in particular the well tests, which are significant in demonstrating the ability of the reservoirs to flow at commercially viable rates.

and an Albian gas condensate reservoir. The Aje-5 well is being drilled from a seabed location close to Aje-4 in 300 metres water depth. The well will be drilled as a deviated well targeting a location close to the Aje-2 subsurface location where that well encountered and tested high quality oil-bearing Cenomanian reservoir. Following drilling, the Aje-5 well will be completed as a subsea oil production well. The drilling and completion for Aje-5 is expected to take approximately 70 days. Following this the rig will be used to re-enter the existing Aje-4 well to complete it as a second
DoC for Iara Area, Brazil
, offshore Brazil. As part of the DoC, the consortium has suggested that the new fields be designated Berbigão, Sururu and Atapú West. The Iara area is located approximately 250 kilometres off the coast of Rio de Janeiro, in water depths of around 2 270 metres. All fields contain good quality oil, of approximately 24 to 30 degrees API. The DoC submission follows an exploration and appraisal programme which began in 2008 and consisted of acquiring 3D seismic data, drilling seven wells as well as performing an extended well test. The encouraging results from this programme continue to
Cairn Makes Second Senegal Find
Cairn has made a discovery of high quality oil in the second well in the Senegal exploration programme. The SNE-1 well is located in 1,100 metres (m) water depth and approximately 100 kilometres (km) offshore in the Sangomar Offshore block with a target depth of ~3,000 m and targeting the Shelf Edge Prospect. Intermediate logging of the SNE-1 well has confirmed hydrocarbons in the Cretaceous clastics objective which is of similar age to oil bearing sands found approximately 24 km away in FAN-1. As operator, Cairn has now issued Notices of Discovery for the SNE-1 well and FAN-1
First Libra Offshore Oil Well Confirms Discovery
Libra consortium reports that drilling the first well in the area extension of Libra, the 3-BRSA-1255-RJS (3-RJS-731), confirmed the discovery of good quality oil in the northwestern part of the structure . Well, informally known as NW1, is located in the pre-salt Santos Basin, approximately 170 km off the coast of Rio de Janeiro and about 4 km southeast of the discovery well, 2-ANP-2A RJS. The carrier oil interval was found through profiles and fluid samples, which will subsequently be characterized by laboratory analysis. The well is still being drilled at a depth of 5,326 meters
