... a significant impact on the well cost and time line. In addition, having the right placement and completion is important for optimizing the drainage contact. To address such challenges during the different stages of the drilling operation, different technologies were used. For example, while the well...

... A total of 28 wells targeting Najmah-Sargelu (NJ/SR) & Marrat reservoirs of Jurassic have been drilled so far in this field including one deep well in South UG in Divided Zone The Marrat Formation in Umm Gudair field is conventional reservoir with 800ft to 1000ft thick sequence comprising...

... Abstract Managed pressure drilling (MPD) helps operators efficiently navigate through narrow pore pressure-fracture pressure windows. The challenges encountered during one onshore drilling campaign included pore pressure uncertainty, high pressure influxes, total losses and high incidences...

... Abstract The ever more challenging environments in which new wells are to be drilled, the uncertainties of the current market, and the availability of effective secondary and tertiary enhanced recovery (EOR) technologies, make the extension of existing wells' life more advisable than drilling...

... LHR>20 C1/ROP is the methane measurement normalized by the Rate of Penetration. Assuming that for a particular formation drilled with constant bit size and constant mud flow rate the gas measurement can be normalized by ROP only Gas components are continuously extracted from the drilling...

... Abstract Horizontal, heterogeneous reservoirs of low permeability present various challenges and drilling risks. The likelihood of encountering potential problems can be greatly increased when there is a minimal understanding of geology and pressure regime in the area of interest. A similar...

... Abstract Most drilling-related incidents are caused by unstable boreholes, whether they are caused by lost circulation, packoff, or stuck BHA and/or casing. One of the main objectives of this study was reduction in drilling incidents and associated Non Productive time (NPT) while drilling wells...

..., structural geometry, mineralogical composition and lateral extent. Drilling wells of any profile has been more difficult than the shallower reservoirs overlying it. The wells have witnessed high non-productive time due to severe wellbore instability issues in the form of stuck pipes, tight holes, hole pack...

... of carbonate reservoirs with well-developed porosity, but low to moderate permeability. This paper discusses the implementation of acquiring Formation Pressure While-Drilling (FPWD) applied for better understanding and mitigating the geological structure uncertainties. The results were used to obtain accurate...

... systems are the primary flowing mechanism. The foremost challenge to produce from these reservoirs is the wellbore interaction with the natural fracture network systems. Despite drilling around 85 vertical and slightly deviated wells in this large challenging HP/HT reservoir complex, understanding...

... along with selection of completion strategy for current set of horizontal drilling Campaign. Drilling and testing results have been encouraging through enhanced reservoir performance in these tight carbonate reservoirs, based on these integrated studies. complex reservoir field development...

... on metals. Due to the continued growth in hydrocarbon demand, operators in the oil and gas industry are always looking to drill deeper wells in order to access previously unattainable hydrocarbons. High-Pressure High-Temperature (HPHT) wells are now broadly present in places like the Gulf of Mexico...

...Well Plan New Engineered Approach Kuwait Oil Company's deep drilling team determined that a new approach would be needed to efficiently drill this section to the desired inclination and azimuth in one run, while meeting the performance requirement. Extensive studies of bit-BHA and formation...

As an independent third party, QRI could be trusted...

... with conventionally drilled wells in mature and depleted reservoirs which have led in recent years to the very significant advances seen in the Advanced Drilling Techniques (ADT) and Technology arena. ADT provides a suite of tools and techniques which have enabled the technical and commercial development of numerous...

... ranges of mineralogy. The objective of this work is to provide a better understanding of SRR quality and deliverability to assist with maximizing well productivity, improving hydraulic fracturing stimulation, and optimizing drilling and completion efficiency. This paper identifies critical paths and key...
