Pengendalian tekanan selama pengeboran sangat penting untuk mencegah terjadinya kick yang dapat menyebabkan blowout dan gangguan keselamatan operasi. Salah satu metode efektif untuk mengatasi kondisi tersebut adalah Engineer’s Method, yaitu teknik well killing dengan satu kali sirkulasi menggunakan kill mud weight (KMW) menjaga kestabilan tekanan dasar sumur (bottom-hole pressure, BHP). Penelitian ini menganalisis pengaruh homogenitas fluida terhadap kestabilan tekanan selama penerapan metode ini dengan pendekatan analogi sistem pipa U. Hasil simulasi menunjukkan bahwa tekanan menurun secara bertahap dari Initial Circulating Pressure (ICP) sebesar 1.134 psi hingga stabil di Final Circulating Pressure (FCP) sebesar 422 psi, yang menandakan bahwa KMW telah sepenuhnya menggantikan fluida lama dan sistem berada dalam kondisi seimbang. Fluida yang homogen menghasilkan gradien tekanan hidrostatik yang konstan, menjaga fluida yang homogen sama dengan menjaga BHP tetap stabil. Dengan demikian, penerapan Engineer’s Method terbukti efektif dalam menjaga kestabilan tekanan yang homogen, mengoptimalkan proses pengeluaran fluida formasi, serta memastikan operasi well control berlangsung aman dan efisien.
