...The 25th Formation Evaluation Symposium of Japan, September 25-26, 2019 -1- FIRST HEXA-COMBO LOGGING WHILE DRILLING RUN IN KUWAIT: A CASE STUDY Khaled Saleh1, Abdulaziz Al-Khudari1, Mejbel Saad Al-Azmi1, Fahad Barrak Al-Otaibi1, Chinmaya Patnaik1, Girija Kumar Joshi1; Anar Abdulkarim2, Ahmet Aki2...

... Abstract Drilling a well safely is the cornerstone of our industry. Fields with complex geology add another set of challenges due to the higher uncertainty on formation dips, fractured or weak formation to name a few. The most unstable zones in the well construction process are thinly bedded...

... section (Sigma), have a high degree of uncertainty. The problem is further complicated by low-resistivity-pay, where the resistivity contrast between water and pay zones is quite small. In this case study, the client drilled a vertical well and acquired LWD triple combo and capture cross section (Sigma...

... Abstract One of the challenges in real-time geomechanics using logging-while-drilling data has been the lack of shear measurements in all formation/mud types. Traditional monopole acquisition only allowed the acquisition of shear in fast formations, so the shear in slower formations...

... Abstract The accurate prediction of the pore pressure and the in-situ stress field is becoming significantly important for deepwater drilling operations recently in the industry. From the past drilling operation experiences in the Sea of Japan, the overpressure and the borehole instability...

... Abstract Drilling in geologically complex or exploratory environments can increase the risk of bottom-hole assemblies (BHA) becoming stuck, with possible loss of chemical sources downhole. Despite this risk the need for accurate logging-while-drilling (LWD) formation evaluation measurements...

..., drilling induced fractures, and breakouts-and all of these properties can be observed through image log. Open fractures have a significant impact on system permeability and open fractures identified through wireline image logs help to estimate qualitative producibility. Permeability is a key factor...

... customization in the process and workflows. The differences were identified through detailed evaluations of reservoir quality(RQ) and completion quality(CQ). However, to address the local challenges during well construction, a new focus is needed with the introduction of drilling quality (DQ). In this aspect...

... Abstract In a large carbonate oilfield located in the United Arab Emirates horizontal drilling has been used to enhance well productivity, injectivity and to reduce water coning. A key to the development of this field is an improved understanding of reservoir characterization to better...

...The 19th Formation Evaluation Symposium of Japan, September 26 - 27, 2013 -1- Logging While Drilling for Shallow Hazard Detection; the Challenges of Large Hole Acoustic Logging Matthew Blyth1, Hiroaki Yamamoto2 and Vivian Pistre1 1 Schlumberger 2 Schlumberger K. K. This paper was selected...

... Abstract High temperature condition is one of the challenging subjects for scientific deep riser drilling. Therefore, precise and accurate prediction of temperature profile beneath deep riser drilling site is very important for the planning and actual operation. Conventional shallow heat flow...

... ABSTRACT Logging While Drilling (LWD) seismic technology has been around for the past decade. With the evolution of the technology comes an evolution in the service for delivering valuable answer products at the right time. This paper address the key components of seismic while drilling...
