... of selected Drilling and Completion Fluids with the SMP from a chemical and mechanical perspective. Downhole conditions were reproduced to simulate Filter Cake flow back behavior in different cleanliness scenarios. 3D Cell with Tomography scan capacity was utilized to perform flow tests and quantify filter...

... the field life. The pressure drop is not constant and/or equal across the field gas levels and it may vary a lot between them. In many cases, the pressure of the single layers cannot be measured since two or more layers are completed to the same casing string. The following proposed methodology allowed...

... ABSTRACT Electrical Submersible Pumps (ESP) are the artificial lift system most used in Eni and its subsidiaries. Even if ESP is a field proven technology, ESP failures can jeopardize the final economic goal in complex projects. With the aim to increase the overall ESP completion run life...

.../day/well. A full-scale test was successfully carried out in 2014 to confirm the technical feasibility of such a system. Two completion designs, (Type A and Type B) were created to deploy the dual boost system in different casing sizes, with components selected to deal with the high stresses...

... reservoirs with the unconfined compressive stress varying between 1.5 and 70 bar. As the reservoirs are made up of unconsolidated sand, the wells are equipped with a mix of Stand Alone Screens (SAS), Expandable Sand Screens (ESS) and Frac Pack (FP) completions to mitigate sand production in producers...

Completion strategy consisted of open hole, ball activated multi stage frac sleeves that allowed to achieve stimulation effectiveness and efficient target reservoir coverage. Focus will also be given on how the selection of the technology to be used was carried out: acid...

... ABSTRACT In the gas fields Adriatic offshore Italy, it has been common practice to complete the wells using single and dual string tubulars to manage production from different reservoirs. These completions complicate the measurement of formation gas saturation using pulsed neutron instruments...

... ABSTRACT Chemical tracers have recently been used to identify oil and water production along different intervals in open hole slotted liner completion, compartmentalized with swellable packers. The reservoir is a fractured carbonate brown field containing several sub-areas producing asphaltene...

... ABSTRACT Total E&P operates several deepwater offshore fields on block 17 in Angola. Historically, due to the quality of the sands previously encountered, the preferred sand-control completion technique has been to use stand alone screens (SAS). However, with recent field developments...
