Drilling

  Dr. Scott Mildren, Solution Lead - Geomechanics Centre of Excellence The importance of geomechanics in the productivity of unconventional plays is becoming more widely accepted.  It is known to directly control rock behaviour and consequently influence drilling ... Read More.

The elastic velocity and anisotropy of shales are significantly affected by the orientation distribution of clay minerals including mica. A lot of research has been done on elastic properties of clay and clay aggregates with varying degree of the platelet preferred orientation. H... Read More.

The results presented in this paper draws on a regional pressure analysis of the offshore areas of the Browse Basin and the southern Vulcan Sub-Basin. The presented study focuses on Late Permian to Recent stratigraphy and a new stratigraphic scheme consisting of 11 main sequen... Read More.

Well abandonment is driven by economic decisions, namely when unit lifting costs are no longer profitable. Generally, governmental authorities require that well operators perform safe and environmentally compliant abandonment operations by establishing a permanent barrier to reta... Read More.

Background and Context In 2016, the Loanan well (214/23-1) located in the Faroe-Shetland Basin was prematurely TD’d as a result of inadequate kick tolerance given the probability of encountering an overpressured igneous intrusion within the secondary target (see Mark et al... Read More.

Abstract Based on wireline logs, core data and pressure information obtained directly during drilling, the various shale units within the Wolfcamp Formation in the Delaware Basin are known to be variably pressured with depth, and the pressure can change laterally within the same... Read More.

  Abstract   This paper presents a case study showing that traditional pore pressure prediction techniques can be adapted to predict pore pressure in an unconventional play by using a newly defined Pressure Reference Trend (PRT) in-lieu of a Normal Compaction... Read More.

Abstract Unconventional operators require geomechanical reservoir characterization to improve well performance. Fit-for purpose solutions are needed to balance the accuracy of the solution and the time and cost involved to deliver products to ongoing operations. We show an examp... Read More.
