... Abstract Offshore drilling is reaching for targets further from shore, at greater depths and in more hazardous geological settings such as in proximity to salt. All these factors heighten the risk of poorly managed mishaps evolving into a major emergency. Onshore monitoring centers observe...

... Abstract The Recôncavo basin is located in northeast Brazil and has several mature fields that have been producing for more than 40 years. After more than three years without drilling activity, an integrated services model was implemented as a different working methodology for optimizing well...

... Abstract The drilling of the evaporitic section using water-based mud (WBM) was always a challenge: even though there are already some wells drilled with saturated aqueous fluid, their use still divides opinions within the technical-academic community of the oil industry. Basically...

.... Other benefits observed are the decrease of the wellbore size required to drill into the reservoir as an openhole completion is to be installed instead of a case hole. In instance, the use of one of the casings is not required anymore. The proposed alternative was initially applied in one well...

... that our development of the Managed Pressure Drilling - MPD technique has helped to overcome the problems that arise due to that field development strategy. At Roncador field we build a trajectory that crosses multiple reservoirs before reaching the objective reservoir, we add to that difficult...

... the tool and the formation. The integration of this data results in better constrained reservoir models and an improved field development strategy. This paper will present the results of wells drilled using extra-deep azimuthal resistivity tools on the Peregrino Field in Brazil. The reservoir comprises...

... The main objective of this paper is to improve drilling performance by obtaining a representative dynamic model of a drilling system: top-drive, controls, drill-pipe and bottom hole assembly (BHA). High-fidelity simulations with a representative analytical model are a goal necessary...

... economic benefits, in such alluring area, local Government presented a series of adjustments in its regulations for E&P industry. However, drilling and producing in Presalt presents technology challenges, due to significant distances from shore, extreme water depths, thick and unstable salt layers...

... As petroleum reservoirs continue to be discovered in ever-increasing water depths, the challenges to drill in these environments become increasingly more difficult. Operations in deep and ultra-deep waters always involve serious risks, which have led the oil industry to invest greatly...

... Abstract While exploring deeper water depths, large hydrocarbon deposits have been found below salt formations. These reservoirs are located in formations called "pre salts". Salt formations create favorable conditions for trapping hydrocarbons but also introduce challenges in well drilling...

... Abstract Drilling and evaluation services require repair and maintenance (R&M) programs to ensure that assets are returned to the fit-for-purpose state before their next application. R&M costs constitute a large percentage of the cost of service for an oil field services company...

The host serves among other purposes as the key well/subsea system tie-in point, support structure, production processing system, (in some cases) drilling operations...

... Abstract The first Tension Leg Platform (TLP) was installed in 1984 to develop the Hutton field in the Central North Sea in about 500 ft of water. It successfully demonstrated the ability of a floating platform tethered to the seabed to drill and produce with surface trees. In the ensuing...
