... Abstract This paper provides an overview of the main efforts that are being endeavored by Petrobras in order to contribute for developing a Brazilian regulation for use and discharge of drilling fluids and cuttings from offshore oil and gas operation, based on operational safety, well integrity...

... Abstract The production of S1 Greater Sirikit Oil Field production primarily contributes from waterflooding operation, where water is reinjected into reservoir to increase reservoir pressure and sweep movable oil to adjacent production wells. Estimated oil gain from waterflooding is expected...

... Abstract Baronia field is located in Sarawak Operations, Miri and started production in the year 1973. It consists of two process complexes BN–A and BN–B. Each of these complexes has its own satellite vent platform which are BNV-A and BNV-B. In line with PETRONAS statement of purpose...

The fluid is also compatible with all contaminants usually found during the drilling operation and meets all the regulatory requirements for the Gulf of Mexico and other deep-water operational areas...

... construction history, but standard simulations using a world-class commercial software was not enough to explain the failure. Thus, a modified thermal analysis for casing and tubing was made in order to evaluate the design safety factor during each operation. This modified thermal analysis consists...

After a period producing, the in-well ESP have failed, and the ALS became the main system to produce both wells, as planned. The project faced some challenges with ALS operation, since there was an expressive flow...

... of switchboards mode: single busbar and split busbar, each of them has yours own vantages and disvantages, but based in its past experienced, few years ago, Petrobras strongly recommended to all its drilling contractors to operate in split busbar instead of a single busbar mode, in order to prevent major failures...

... Abstract A major cause of remedial operations from production liner cementing is not achieving isolation from reservoir to surface. Occurrences increase in wells with inclinations of approximately 90° and necessitate isolating areas close to the liner overlap because of the difficulty reaching...
