... Abstract Managed Pressure Drilling (MPD) is a method of controlling wellbore pressure using specialized equipment and techniques that adjust bottom hole pressure in real time. It can be performed with automated or semi-automated systems and trained field personnel, including operators or rig...

... Objective To obtain the major benefits of having a long open hole completion with maximum multiple reservoirs contact, full control and optimization over the flow without coil tubing intervention have become a challenge for the operators. This paper presents a step change in the engineering...

... Abstract Casing Running Tool (CRT) combines many functions of other tools, such as circulation heads, casing and tubing rotation, and connection makeup. The technology's initial design was for drilling with casing. However, it is currently used widely in running and makeup operations...

... depletion in drilling through reservoirs. Several concepts were evaluated, and a packer in the drillstring was defined as a necessity by the major oil company. Drilling through depleted reservoirs has become more and more common in operations run by both oil operators and drilling companies, in fields...

... is made up and afterwards until the dual completion tubing hanger is finally landed in the wellhead. This simultaneous operation surely presents more operational as well as safety challenge to the tubular running and rig floor personnel. In addition, these, completion tubing come manufactured...

... Abstract In the past decade, the operators and service companies are seeking an integration solution which combines engineering and geology. Since our drilling wells are becoming much more challenging than ever before, it requires the office engineer not only understanding well construction...

... these issues in ensuring long-term well integrity and productivity. The factors affecting cement bond integrity are generally related to reservoir properties, well profile, cement design and recipes, general operational issues, and Wait on Cement time (WOC) ( Zulkipli, 2021 ). Evaluation of cement quality...

... Abstract Decommissioning of end-of-life wells is an essential operation in the lifecycle of a well and requires thorough planning and execution. The plug and abandonment of the wells contribute over 45% of the overall decommission costs and hence there is a clear mandate from the operators...

... Summary The bismuth alloy technology is capable of permanently and eternally shutting-off gas migration in single or multiple casing annuli by forming a V0 rated Metal-to-Metal gas tight seal. For P&A operations the bismuth alloy barrier technology results in a significantly higher level...

...) therefore, 3 × LCM pills of different concentrations were pumped and squeezed into the formation with SBP to enhance the NMWW to 0.035sg EMW (245 psi) deemed necessary to kill the well and retrieve BHA. MPD allowed efficient cement squeeze operations to be performed in order to cement the fractured/weak...

... well operations. Fortunately, with the wave of digital innovations that are sweeping the industry, most E&P organizations have a wealth of opportunities to streamline activity and increase efficiency while reducing the resources required. However, with the increasing array of digital opportunities...

... Abstract The reservoir formation in a major oilfield in South of Iraq is highly fractured. The operator has set as requirement that any losses had to be cured before drilling ahead. Whenever losses are encountered, drilling is stopped to cure the losses, most of the times spotting at least four...

... Abstract Drilling horizontal wells with a high dogleg severity (DLS) of 10–16 deg/30 m is the approach that one operator in Oman adopted to drill the buildup section. The 8½-in section used to be drilled with a conventional motor BHA, which took around 4 days to complete. Due to the high DLS...

... Abstract A 5-well rig-less & explosiveness abandonment campaign by 2 project partners operator and service provider was made a reality in Morocco whereby a novel method of cementing squeeze of perforations and an annular fill-up were established in one single operation. This is called LEAN...

... coiled tubing drilling (UBCTD) was introduced. In order to address the harsh downhole challenges such as high temperatures, deep burial depths, under pressured reservoirs, abrasive and hard sands and logistical constraints; a fully integrated well delivery solution was developed jointly by the operator...

... Abstract Managed Pressure Drilling (MPD) solutions are no longer the anomaly to Operator strategies, but rather another tool in their belts. With this continual utilization, MPD is evolving to become compact, more effective and safer. The inventive use of a Nitrogen Backup Unit (NBU) has...

.... When attempts to release the stuck pipe by jarring or acid fail, the operating company and drilling contractors are left with little option but to sever the drill string and prepare for side-track operations or even abandon the hole. Traditional pipe severance methods in the event of a stuck pipe...

... performance through autopiloting. Overall, these new products improve the working environment and overall efficiency, which also results in more cost-effective well construction and safer operations for the rig crew. Upstream Oil & Gas DCR active noise configuration mechanization Drilling...

...Lab testing Over the past several years, there has been an increased demand by both drilling contractors and operators on elastomer performance under chemical attack. Introduced chemicals like corrosion inhibitors in drilling mud as well as naturally occurring impurities like hydrogen sulfide...
