Tech Paper: Design Procedure for Cementing Intercalated Salt Zones

Tailoring the right cement design to maintain well integrity across salt zones Wells often require being drilled through and cemented across salt formations. In many parts of the world, salt sections consist of multiple salt types. These include Halite, Carnallite and Tachyhydrite. The last two salt types could move one hundred times faster than Halite and are chemically reactive. Typically, Carnallite and Tachyhydrite occur as streaks...

Tech Paper – Behind Pipe Log Evaluation Study: Deepwater Subsea Abandonments in the Gulf of Mexico

Pipe evaluation techniques can help reduce the cost of removing casing strings during plug and abandonment activities New techniques for well abandonment log evaluations have been under study since 2012 in the Gulf of Mexico (GOM). Legacy practices typically used acoustic methods consisting of cement bond log and ultrasonic scanner devices. The new methods described in this paper consist of adding nuclear sensors to supplement the...

Tech Paper: Advanced Geosteering Technology Promotes the Accuracy of Well Placement in the Thin Reservoirs of China Mature Oilfield

Safely and efficiently maximize reservoir exposure in mature fields After more than a decade of producing oil from the thick marine sand reservoirs in the HaDeXun oil field in the Tarim basin of western China, focus has shifted to the challenges of drilling thinly laminated reservoirs. To maximize efficiency and production, geosteering services, as well as bottomhole assembly (BHA) and bit optimization, were used for the...

Tech Paper: Development and Field Application of an Innovative, Minimally Damaging, Low-ECD Invert Emulsion Fluid for Enhanced Drilling and Completion of HP/HT Wells

Multi-purpose fluid improves drilling efficiency, reduces cost and minimizes production impairment As known the first application experiment for lifting fluids was conducted in Germany in 1797. Then the idea was developed in 1846 utilized compressed air to lift oil from wells. This paper describes the first field application of a high-pressure/high-temperature (HP/HT) organophilic clay-free invert emulsion fluid (OCF IEF) weighted with small-particle-sized (SPS) barite, qualification of...

Case Study: eRED® Valve Saves Six Hours Rig-Time for BP

eRED® Valve opens and closes remotely, eliminating the need for wireline intervention CHALLENGE – BP needed a more efficient method to set a shallow barrier and to reduce rig time for pressure-control equipment (PCE). In doing this, BP wanted to ensure that the solution chosen would adapt to the existing completion infrastructure that was set in the well. SOLUTION – This water injection completion consisted of...

Tech Paper: Auto-Gas Lift and Smart Well Completion Challenges to Extend Well Life and Running toward Cost Effective Program, Field Case Study

The concept of this completion is to use the gas cap energy from different reservoirs to lift the heavy and high water cut wells As known the first application experiment for lifting fluids was conducted in Germany in 1797. Then the idea was developed in 1846 utilized compressed air to lift oil from wells. In year 1900 the lifting done by compressed air injected through the...

Tech Paper: Developments in Sandstone HF Acidizing: HF Fluid Compatible with Na or K Brines and Carbonate-Laden Mineralogy for High Temperatures (360°F)

Aminopolycarboxylic acid chelating agent helps with the removal of mineral buildup in sandstone formations Using hydrofluoric (HF) acid for the removal of clays and silica minerals impairing permeability in sandstone formations requires fluids free of sodium or potassium ions. High temperatures (> 300°F) further limit HF acid use and its effectiveness because of potentially damaging effects to the formation and its corrosivity. This paper discusses laboratory testing of...
