“…Notably, it can be employed to successfully predict viscosities for normal and branched alkanes, aromatics, and cycloalkanes, while the predictive power of the corrected PCSAFT-FT is sufficient only in the case of normal alkanes. [101]. This apparatus, which is located at NETL's Morgantown site, was designed to measure the viscosity of drilling fluids with viscosity values of 3-300 mPa s employed for ultradeep drilling.…”

The NETL-RUA leverages its expertise with current fossil energy sources to discover and develop sustainable energy systems of the future, introduce new technology, and boost economic development and national security. Cover Illustration:The image provides an inside view of the density cell, which is capable of getting density data at 500°F and 35,000 psi. The left side image shows the bubble point of the gas. The tiny bubbles can be seen at the top center of the cell. The middle image shows the liquid-liquid-gas equilibrium phase exhibiting two liquid phases at the bottom and in the middle sections as well as a gas phase at the top. The right side image shows the solid formation as the pressure is increased.

In this paper we report our new approach to synthesize cationexchanged Laponite suspensions. General observations of the prepared samples indicated that an aqueous suspension of 1 wt% Laponite retained its free flowing liquid phase characteristics even after aging for several weeks. When bivalent cationic metals (Cu, Co, Ni) were ablated into the suspension, the strong charge of the crystal face was reduced and, on standing, the suspension gelled becoming highly viscous. This solgel transition was induced by the formation of a spacefilled structure due to both van der Waals and electrostatic bonds between the pos itively charged rims and negatively charged faces. Rheological properties of such prepared suspensions were measured using a Brookfield DV1I Pro Viscometer with a small sample adapter (SSA18/13RPY). The yield strengths of 2.2 N/m 2 ,3.2 N/m 2 , and 1.7 N/m 2 were measured for Ni, Co, and Cumodified Laponite suspensions, respectively. These yield strengths are sufficiently high for suspending weighting materials such as barite which requires the gel strength of about 0.5 N/m 2 .Published by Elsevier B .V.

The design of an invert emulsion fluid that can hold up more than 24,000 psi and 435°F is a complicated and exhausting process. The challenges presented in the design of an UHPHT drilling fluid formulation are the base oil selection and the complete drilling fluid formulation. Flash point measurement of base oil before and after heat ageing to ensure that the base fluid were stable and the overall stability of the mud system need to be assured (rheology, gelation, fluid loss and weight material suspension) after both dynamic and static ageing for at least 96 hours at anticipated maximum BHST. Laboratory pilot testing allows us to find a chemical balance where the rheology profile and mud properties fulfill the UHPHT project requirements. The laboratory testing protocol validation is the most important factor to prevent different issues during the drilling phase. This testing will be a contributor factor to conclude a well successfully. Another phase of the design that we need to consider is an exact dynamic temperature modelling because a more precise Bottom Hole Temperature profile helps optimize the drilling process to increase the possibility of borehole stability.
