PHPA Partial hydrolyzed polyacrylamide
Partially hydrolyzed polyacrylamide (PHPA) is a copolymer, substance formed when two or more substances are polymerized simultaneously, resulting in a product that is not a mixture of individual polymers, but a complex which has different properties from each polymer by separated. The PHPA case we refer to a polymer of high molecular weight whose main function is likely to inhibit shale hydration.
Partially Hydrolyzed Polyacrylamide (HPAM) in act with water after polymer flooding in oil filed reasons in environmental troubles, such as enhancement in the oil-water detachment trouble, natural degradation to make toxic acrylamide and jeopardize local ecosystem. Bio-degradation of HPAM may be a cost-efficient mode for solving these problems.

Poly Cat鈩?/b> is an Acrylamide based polymer having high degree of cationic charge. It has been designed specifically for sludge treatment and to aid the dewatering of drilling cuttings prior to processing on centrifuges, vacuum filters and belt press.
Partially hydrolyzed polyacrylamide (PHPA) is a widely used polymer in the oil and gas industry due to its lesser cost and good water solubility. PHPA is used as a functional additive in water-based drilling fluids. The PHPA mud system stabilizes shale formations and influences cuttings and wellbore stability. PHPA can be used in mud systems varying from low solids to weighted muds systems utilizing fresh or saltwater.

and research for this project. A deep study of Partially Hydrolyzed Polyacrylamide (PHPA) polymer is conducted and author had selected HyPR-CAP PHPA and Polymer Test Kit to be used in this project. The need for a reliable, quantitative analytical method for the determination of the PHPA polymer content of drilling
PHPA Polymer Concentration Test Instruction Manual
The PHPA test is a modified Kjeldahl method to measure partially hydrolyzed polyacrylamide (PHPA) concentration in mud systems. In this test, the sample is reacted with sodium hydroxide (caustic digestion) at 200 - 250. o. C (392 - 482. o. F). Ammonia is liberated as hydrolysis of the polymer occurs. The ammonia is distilled into a boric acid
Partially hydrolyzed polyacrylamide (PHPA) is the most frequently used polymer in this respect, owing to its low cost, viscosifying nature, and well-known physiochemical properties (Urbissinova et al. 2010). The molecule of this polymer is a flexible chain which remains in coil-like structure in the absence of a shearing effect.
Evaluation of polyacrylamide-grafted-polyethylene glycol
The most common polymer used for shale encapsulation and borehole stabilization is the partially hydrolyzed polyacrylamide (PHPA). The polymer based mud having PHPA as a mud constituent has tendency to form thin impermeable filter cake at the wellbore, which is advantageous to mitigate wellbore instability problems.
Preparation of stock polymer solution. Stock polymer solutions were prepared at a concentration of 0.01% for spiking in the samples. The polymers were prepared using a jar test apparatus (Phipps and Bird, USA) by mixing 0.1 g polymer in 1000 mL of deionized water at a speed of 220 rpm for 5 min, followed by mixing at a speed of 125 rpm for 55 min.
Polyacrylamide degradation and its implications
The hydrolyzed form of polyacrylamide (HPAM), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic PAM in oil and gas development as well as in soil conditioning. 1,9,12,21
(PAC) and partially hydrolyzed polyacrylamide (PHPA) polymers are chosen for studies. Each of these polymers at different concentrations was added to 3% bentonite-water suspension to obtain most suitable water based drilling fluid. Effect ofCMC The effect of concentration of CMC on rheological properties is shown in Table 2 and Fig.
